I emailed Mike about my Rinnai issue. Very soon after, we spoke over the phone. I can't say enough what a kind and intelligent person this guy is. Thanks for all your help!
One of the Best Instructional Videos Ever! Clear, tight, concise. Information in every sentence. No wasted time. Right to the point with accurate info. You could teach in a Vo-Tech School. Thanks.
Thanks again for your advice ! I swapped out an old unit that had a leaking heat exchanger for a whole new, identical unit. All the plumbing and vent lined up without much problem. Hot water again! For those of you out there who are contemplating work on a rinnai ....listen to Mike ! He really knows what he's talking about.
I will be installing my first Rinnai in a month. I may need to call you to discuss whether or not I will need a PRV. Thank you for these videos man, they are priceless. You are doing God's work for plumbers.
As Jay Leno says, “there is always a guy who knows it like none other.” You are the Rinnai. We just installed our exterior unit. Best videos on tankless. Also love your shop! Thank you video on my channel!
I just completed my RUC98i install in Michigan. I could not have finished without Mike as a resource. I called him 4 times over the weekend and he could not have been nicer or more helpful, especially since there was nothing in it for him. Rinnai should be thankful to have an dealer/installer like Mike. After Mike clued me into the aggravating hidden mixer valves in my master bath (no more daily complaints from wife about bath water temp), the unit is running great. Even with very cold incoming Michigan water, it is cranking out 130 degrees no problem.
Mike, thank you so much for taking time on a Sunday night to call someone 2000+ miles away! We appreciated your troubleshooting our lack of power on our Rinnai propane water heater. It was great talking with you. You are definitely an expert on Rinnai!
This guy is awesome. I needed several answers regarding my Rinnai tankless install. I am not even in his area and he still took the time to talk. If it wasn’t for Mike my local installer would have made a few poor choices when installing my Rinnai. Thanks to Mike several counties over....I had a good install. Thanks Mike!!!!!!!!!
Thanks Mike. I have a Rinnai unit in my house, been operating flawlessly foe 16 years. I clean it with a pump, a couple of buckets and vinegar. When I need a new unit it will be a Rinnai. Excellent video(s), keep up the great work!
Bob Colorado wow that’s great! I tell all my customers if you take care of the tankless it will last 20 years. I will forward your comment to the Rinnai Rep. I glad to hear it’s working good for you. Could you send me the model number and the state you live in. Mike
First let me thank you for answering my call, and giving me the information I needed. I will continue to watch your videos, and try to learn as mush as I can. You are a very good teacher. Thank you once again for your training.
The Rinnai Guy is the Man to watch! Clear, precise, and extremely informative. He even utilized his personal time to return my call and personally assist me with my questions that I posted to RUclips. Pleasant man to speak to. Thanks again Mike. Your help is truly appreciated.
This guy is frikkin AMAZING!! I had some questions about installing a V65i on my converted skoolie and he called me and helped me out! makes the internet worthwhile. Am going to post pictures when I'm done - THANKS MIKE!
I'm so glad that I found this. Other than contractors that hate DIY home owners (including my electrician brother some of the time) I don't see why anyone would give this video a thumbs down. I was trying to decide which brand of tankless water heater to buy with the Rinnai definitely up in the running. I will go with the Rinnai mainly because of your videos and clear explanations. You have removed any reservations I had and answered any questions I have (and probably many I would have had). I have a 1100 square foot house (built around 1945) in Michigan with one bathroom, kitchen sink, washing machine and laundry tub with a (new) well for a water source. This used to be our summer cottage and now a full time home. It's a small house but being I traded square footage for lake frontage it's what I have. There is just my wife and I now so there is no big drain (pun intended) on the water system so I figure that a 6.5 GPM 150K BTU system should work out fine. My one significant concern is the well water quality but being I am also doing a major upgrade on the water filtration system (which will probably include a poly-phosphate filter) I don't think it will be that much of a problem as long as I do the maintenance on the tankless. My current project is replacing the mix of copper, galvanized and PVC plumbing with PEX and moving all plumbing mechanicals into a small utility room that also contains my force air furnace. I only decided to move everything into the furnace utility room because of the space saving feature of a tankless water heater. So being the current water tank is 14 years old and won't fit comfortably in this utility room and to me a tankless water heater is a 'no-brainer' it is the path I am going on. I would add that I am doing much of the plumbing work in an 18 inch high encapsulated (previous project) crawl space. I think I will be going with the Rinnai V65iN. I would go with the Energy Star rated top line model however Rinnai 'mandates' that it ONLY be installed by a licensed professional or the warranty will be voided. With the Value line it is only 'recommended' to have a professional install it and there is no mention in the warranty that it would be voided if not using a pro. The price difference between the two would be slightly offset by the $100 rebate ONLY for an Energy Star rated water heater. Personally I can't understand why warranty is voided if a pro doesn't install the luxury Energy Star line but not the Value line. Over the last forty years I have probably installed over twenty standard water heaters not to mention done ALL maintenance and renovation on any house I have owned for personal use or rentals including two that I built from the ground up. I always go by code and don't cut corners but I have done a LOT of cussing dealing with work that previous owners have done far to many times to count. On the few occasion that I have missed meeting code on anything the building inspectors always point it out and have me correct it. The inspectors have always been fairly strict with home owners over pros and I have learned that it is NEVER a good idea to argue with an inspector - even when they are wrong. I have had follow-up inspectors tell me that I did NOT have to make a change because the work was actually up to code before hand. It's not uncommon for building inspectors to disagree with what is code. But again it is not worth it to argue. So after reading my very long winded comment I would appreciate it if you have any comments or suggestions. Thanks!
Huge help brother. I know you must get a lot of calls and I truly appreciate you taken the call and helping us out! You answered questions for us that even tech support couldn’t. Thanks again!
Super guy! Emailed him a question this morning and got a reply around noon! He told me to call after 6 pm if I had any more questions. I called and he discussed the issue completely and offered more help, if needed. Very knowledgeable. I am extremely impressed!
Wanted to thank you for this amazing video - I was able to buy this unit and install it myself, replacing my tanked water heater, and I couldn't have done it without this video and a couple of your other videos. My RL94iN has worked for over a year now with heavy use without even a single issue, and I give you all the credit for this. The detail you go into was just priceless and right on every time.
@@humblebragger500 at the time I purchased it, it did not come with wifi - I think they sell a few compatible kits that add on this and other capabilities.
Mike, good job on explaining the basics of a tankless water heater. This is much needed, I find many plumbers shy away from installing tankless heaters because they don't understand them, or they have had a bad experience with one when they first became available in the United States. I'm looking forward to future videos and will be telling folks to check out your channel.
R. Dowden thank you very much, that's why I started this channel. I too had very bad experiences with tankless heaters when my business was in NY. When we moved to Florida I researched and tried out Rinnai and never looked back. Thanks for the comment Mike
First off, I want thank you so very much for your videos. They are awesome and gave me the confidence to tackle my installation after several attempts at getting a pro to do it (either they never replied or gave me a $5k+ estimate). We were without hot water for two weeks! It took me several days doing it alone, but I took my time, especially with the venting. Unit works great 👍. We have hot water 🙏🏻😁 Also, thank you for answering my questions via email! I seriously could not have done this install without your help!
I was looking for all the extra part that goes with Rinnia, in this unit that is not included. And I enjoyed your presentation on the Rinnia tankless water heater.
This was an exact replacement for the old one that lasted about 10 years. ruclips.net/user/postUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh The top of my mitigation tube by my roofline was just a 90 elbow which allowed too much debris to fall down into the fan, eventually ruining it. Without this issue, I bet it would have kept running another 10 years. When I replaced this fan, I added an extra elbow joint so the top tube now it does a 180, which should solve that problem. The radon guys around here wanted to charge me a $300 diagnostic fee, then parts/labor (probably close to $600 total). I installed this all by myself in about an hour for the cost of the fan; it would probably be even easier/faster with two people. FYI the manufacturer's warranty greatly differs depending on whether you install it yourself (1 yr warranty) or have a licensed installer do it (10 yrs).
Just ordered a rinnai RU160 and vent kit to install under the house in place of the old tank heater. I'll be watching your videos for awhile, I'm sure. Wish me luck (and thanks for the videos)!
Mike-THANK YOU for answering my email and taking my phone call after your work day to walk me through my attic install. You are a gracious wealth of info. Sei fantastico.
Mike thanks for answering all of my questions regarding how best to vent a tank less condensing water heater in my basement that needs to vent via my abandoned oil furnace masonry chimney. If you ever get to Seattle, look me up and the coffee or beer is on me! Frank in Seattle
mike, love your videos. between your videos & reading the installation manual cover to cover (several times), i have no doubt i can install the RU199iN i want and do it just as well as a pro, for about a 1/4 of the cost. however, if i do install myself, Rinnai WILL NOT honor their warranty. "In order for this warranty to apply, it is required that you use a trained and qualified professional who has attended a Rinnai installation training class before installing this water heater." that is straight out of their installation manual. i contacted Rinnai and they confirmed this is 100% true. Not telling you what to do, but maybe you should mention this in your videos. All of the confidence i have gained to DYI this unit almost made me make a $2000+ mistake. it's a machine, things will go wrong, and Rinnai would not have covered the repairs. because of this, i have no choice but to install a Rheem. i can replace the Rheem 4 times for what it would cost for me to have someone else install a Rinnai just once. still, your videos have been a HUGE help. thank you!
Thank you. This was very helpful. A different video mentioned the exhaust / intake as concentric; I had no clue what they were talking about except that I "assumed" (correctly). You went out of your way to describe the exhaust/intake vent kit. Very helpful. More and more people are going this way to save money and not waste ... ideal ... and even so equipment is getting more and more efficient. The only issue is the cost of installation; pricey up here in the northeast.
Thanks so much for posting this Mike. My son is going to get a tankless water heater very soon. This video as well as your "installation" video are very helpful! Bob in Virginia
Bob Troxell he will not regret it. The new Rinnai units are so very well made and if maintained every year will last 20 years. Thanks for the comment Mike
Just a fyi if you cut 3 inches off the plastic you still cut 3 inches off the stainless. It starts 1/2 inch longer so you take the same amount off each and its still half inch longer
Thanks Rinnai Guy! You just saved me money, and time. I have been fretting over how I was going to run this 3/4 inch pipe which I would have run off a capped 3/4" Tee coming off of an 1" pipe approx. 10ft away. Especially when I have a 1/2 inch pipe approx. 2 feet away from where I need to install my RL94I. I will used a Tee to increase that line to a 3/4" directly to the Rinnai as you said at 14:02 in the video. Oh yeah Mike, This statement is also a request for confirmation if I should proceed with this plan as I suggested.. Thanks for you knowledge. Looking forward to your reply. Thank you.
I have to get back to work but I wanted to say, this is an Excellent Video, Thank You Very Much, You are an Excellent Speaker and I am going to subscribe. I am putting a Rennai 199 Hot water heater, pulling my own permits after our gas company wanted to charge me $4000 dollars to install. Thank You, Robert
Tilting the vent to drain the condensation outside is a great idea for places in a warmer climate. The manual says tilted back so that the condensate comes inside. I believe the reasoning is that you could build up a giant stalagmite of ice and clog the vent
Hi , I’m hoping you check in often! I live in Belmont Maine in a Log Cabin that we purchased in 2021 , I would like to upgrade to a Tankless hot water heater. Please Know that this cabin is 100 percent off Grid with Solar and a Windmill and a 12,000 watt generator. With this being said this cabin has everything you need and does not suffer any power issues at all . 4season home with no problem, for 17 yrs by the Previous owner , we So the stand up hot water heater is propane fed , we would like to stay with Propane!! Also when we are not here the cabin is shut down completely!!!!! So the unit would have to have the capability of being shut off and restarted by myself . Just like the existing hot water heater,Gas stove, gas Fridge,we have now. The cabin has plenty of electrical boxes for power source, the unit would be in the concrete basement where the hot water tank is now . The Venting of the hot water tank comes out of the top , turns into a 90’ goes straight for 36’ thru wall to outside with a cap on it . If you could make any Recommendations for this Project ! I would Appreciate it . Thank You
Thanks a bunch for the videos. Am going to be installing the RUR199IP. I've seen some Rinnai diagrams and other videos that include an Expansion Tank. Noticed that your installations do not. Can you please tell me when I should/shouldn't use one with the 199IP? Also, the instructions note that there is an internal check valve in the supplied hot water return fitting, do I need an additional check valve on the return line as you demonstrated? Thanks much
If you have a lawn sprinkler system with a RPZ back flow device I would def install a ex. tank. If not you can if you like it won’t hurt nothing. As far as a check valve on the hot you do not need one. I hope this Mike
Just wanted to publicly thank you for responding to my Hail Mary call last month. We truly appreciate your call, follow-up and are hoping that your reference comes through. Sincere Thanks To You Either Way!! 🙏🏽
Great video! I have a question. I am installing a Rinnai non condensing unit. The vent needs to go 3ft to the ceiling and another 12ft horizontally out the side of the house. Do I need a condensate trap if I slope the horizontal section? Thank You!
SO my only hang up in swapping to tankless would be the venting. Current tank is in the middle of the basement venting out a chimney. It would be a long run (15 FT) of venting to get it to an outside wall.
What happens if my home is ran with half inch copper height no 3/4 should I not put a tankless in and stay with the tank I'm worried about a half inch lines not being sufficient thank you appreciate everything you do
Thanks for your efforts here. I have an 11 year old RL75i that is leaking water from the copper boxes above the box that holds the flame. It still works and heats the water but water is dripping out of the unit. Seems like some crack or something inside? Anyways, I may want to replace the whole thing rather than paying somebody $600-700 to take it apart to try to fix it. I can buy one for $1200. It seems it wouldn't be too much work to switch in a new unit since all the plumbing and venting are in place already. Can I do this myself? Or is ther a lot more to this than I'm thinking?
excellent video thanks - busy installing a rsc199EN after our little takagi blew out after 15 years and this is worth gold! Will def be following up on that vinegar trick, maybe a short detailed video on that showing what u do (filter in/ out etc?). Thanks!
First of all I live in ILL. purchased a Rinnai tankless ( in transit ) tried to locate the gas pressure reg. you use. did not find yet, however all info I came across indicates one is not needed due to it is built in the unit???? With that said MY total system requires at max. cap 359CFH. Gas Co. installed a meter with 10lbs pressure and a cap for 425CFH. I believe a pressure reg. is needed to handle the 10lbs. What you say? Thanks for all that you do. You help a lot of people!
The hot water valve I have won’t screw on to the hot outlet pipe on my Rinnai, model #RUCS65i. I’m use the Rinnai valve kit #MIVK-T-LW. It appears that the hot outlet pipe is ¾” NPT and the valve appears to be ¾” SPT. The cold water valve works fine. It just screws on and seals to the cold inlet. At 13:01 on this video, I’m looking at your hot/cold hookups. On the hot side, I’m seeing what appears to be a bushing between the hot outlet nipple and the hot valve. Can you tell me if I’m seeing this correct and where to get that bushing? I called Rinnai and they couldn’t/wouldn’t help me. I’m not a plumber. Thanks in advance.
Mike I got a brand new V75in Unit. It vibrates when washer is turned on? Any idea of what it could be? It does not vibrate when kitchen/ shower faucets are on? Please advise. Great videos. Watch them all. Thank you.
Great video Mike. Just a quick question. Is there a building code restriction about how far the exhaust termination needs to be from an operable window? What about a roof overhang?
Hi Mike. We have a Rinnai tankless for 7 months. After about 5.8 minutes, the heater shuts down and cold water flows. After sitting for several minutes, hot water will flow again, but for only 5.8 minutes. From what I can observe, the installation was properly done. No error codes come thru. Also, I cleaned the water inlet filter. Any advice would be appreciated. Model RUCS75i. Purchased new from Big Box. Installed by plumber. Vented outside. Concentric? 1 exhaust.
I had the same issue with my tankless. Turns out my showerhead was getting clogged up with scale. We have hard water in our area. Remove the showerhead and clean the screen. It does the same thing with our faucets. Remove the aerators and clean them out.
Great videos Mike. Because of you I purchased and installed a RL94i around mid March 2019 and it has worked great and would reccomend it to others. But now we have a problem and hate the thought of taking such relatively new unit apart for repair. We have not been home for the last two days so no hot water use. Now the unit is showing an error code eleven when we turn on hot water. After turnning the hot water back off the code clears. I have turned the heater off then on via the key pad, un-plugged the hearter electrical cord, then I removed cover and all looks good. Lastly I removed and inspected the igniter and flame sensors which were clean but wiped them off anyways, reinstalled the assembly and tested for good ingniter spark. But, still code eleven each time we try to use hot water. Next was search RUclips for a fix. I cant beleive the burner is dirty or plugged already. Any suggestion would be appreciated.
I am installing a Rinnai RL75eP TWH. My home has vinyl siding and my question is, are there any precautions or special instructions for mounting on vinyl siding? In one of your excellent videos you showed installing the interior models on 2x4s for the vent spacing. I was wondering about the heat from the back side of the exterior unit. Thanks...
Hey Mike thankyou for explaining we have a Rinhnni 160 in the main gas line is hitting the top of the concentric pipe rt below the 90, I'm thinking about hitting in with a heat gun and while pressing a 1 1/2 pipe to mold it . Another question 🤔 it says i need to pitch up 1/4" per foot so only 1/2 " rise. To have exhaust rise out, but did you say point vent down for condensed. Thank Mike ill send a picture if I can Sincerely Dan O'Brien
Thank you Mike. This is probably the most informative video I've seen on RUclips. My question is about how to vent this unit if its on an interior wall? How far can I run the vent stack.
a question. I have a rinnai v94ip and I ordered the vent but it came with the plastic inside pipe (gray color), can I connect it? or do I need the vent with the metal pipe inside. I think mi rinnai is non-condensing. Thanks so much
I have purchased a Rinnai V65ip that I'm installing this weekend at my cabin. You mentioned that you have a video of the install from start to finish. I have watched several of your videos, but I can't find that one. Could you guide me to it. Also, I can't find your email you mentioned. Thank you so much for your videos. You have done an amazing job and given me what I need to do this right. Thank you!
Nice Video. 3 Questions: 1-Would you install 2 units (so that both units go on as soon as hot water is needed) I will have 4.5 baths, 3 kitchens, 3 laundries rooms/ between 7/9 adults in the house. Planing on getting 2- v75in 2-Whats the longest Exhost distance to outside allowed?/ Whats the minimum clearance from both exhost (assuming Scenario 1)/ Would unit come with 8'/10' of duct, would i be able to purchase coupling and extra pipe just anywhere, whats the cost? 3-Would my V75in package bring service valves?, If not, Would I be able to purchase them just anywhere? 3-Would you, or your supplier, supply me the Units/ exhost lines, service valves? Thank you
What I’ve been trying find out is does Rinnai make an attachment to cover the intake, the outdoor aspect, screen to cut down on the amount of larger insects from entering the unit? It can be a problem especially during years of a lot of moths or wasps, I think I can design one that won’t interfere with the exhaust. My intake/exhaust pipe is longer than the one shown since it’s about 13 years old. I’ve been looking for such an attachment pretty much everywhere.
Great Video! Although asked by another guest I was unable to find a response? Installing a RL75IN in a home with 1/2” plumbing. I can step up the line to 3/4 supplying the unit w cold water and obviously do the same to the line delivering heated water to main 1/2” water line supplying the house. Will this work or do you have to step up more if not all hot water delivery plumbing? Thanks
Such a fantastic video! I just had one installed yesterday and way too much of the white plastic sleeve was sticking out the side of the house. Looks like a missile hit us! I’ve asked him to trim it back and make it flush...I’m hoping he stands by his work and will do it for us. Also, how can I be sure that there is a proper pitch for drainage?
Thomas Yergovich yes you can. You have to cut the outer pipe first and then you need to cut the inner pipe 1/2” longer then the outer pipe. The inner pipe the exhaust goes in 1/2” more then the outer pipe the air intake. I hope this was helpful. Mike
You mentioned 3/4 inch cold water intake as a requirement. My house has 1/2 inch pipes. I plan on installing the Rinnai High Efficiency Plus 7.5 GPM Residential 180,000 BTU Natural Gas Interior Tankless Water Heater. Are the requirements 3/4 inch on that unit as well? Is there a unit that allows 1/2” ? Thanks
Thank you for the videos. I am trying to troubleshoot the operation of RL94iN. When opening, then closing a cold valve anywhere in the house, the RL94iN exhaust motor turns on for a second or two. I am told something is wrong. I am the homeowner.
There is something bypassing to make the water servo valve turn for a few seconds. Did you add or repair anything in your plumbing system. You can call me at +19042385349 and I could go over it with you
When installing multiple units utilizing concentric vent pipe. What is the minimum distance horizontally from each exterior wall penetration, between Rannai and furnace concentric venting? And if a dedicated re-circulation vs. cold water return where should the expansion tank be installed? If the cold water return is used with a bypass valve is a external pump needed?
Alan Kunkes the vents should be a minimum of 12” apart. I like them to be 14” apart. The themed tank should be put on the cold water feed. If you have a dedicated recirculating loop and the Rinnai units are the condensing models the pump should be put on the last units cold water line. If you want to call and talk to me e mail you contact info at Economyplmbg@aol.com Mike
Hi Mike, Thank you for the quick response. I very much appreciate it. Yes, I will contact you at some point in the near future with a couple of questions. I have found your videos to be very good and useful. Thanks again.
Hello Mike, I have a 21” vent for the non condensation unit and need to cut it down. Do you cut it down from the elbow end? If so, how do you remove the elbow. Thank you
Hi Mike , great videos !!! I have a question , You explained how to do vertical venting through a roof but I'm in a basement and need to do vertical venting and go above the snowline. I'm coming out just above ground level and need to go up. Any advice ?
Jerry L from Philly Great videos Mike Thankyou...installing a rinnai v95in tankless with horizontal exhaust thru the rim joist of a basement ceiling. Horizontal exhaust will terminate about 3 inches off the ground.. I know it should be at least 12 inches. Vertical venting is not an option....any suggestions
Thanks for making these videos, they are great and helpful for DIY community. I am also planning to upgrade to tankless water heater next week. I live in Texas and my unit will be in a closet 2nd floor. My vents are going over the roof. I do not have a luxury to drill a new hole for the new exhaust. I am thinking to use the existing vent for the final 2 feet of the pipe (PVC pipe from the unit to the roof and connecting PCV to the metal pipe 1 to 2 feet below the roof). Also I am planning to use intake pipe ending in attic instead of going out. Attic is huge not sure if it makes difference. If possible, can you please let me know if it is OK to connect to the last two feet of the existing exhaust and leaving intake end in the attic. Appreciate your (any one in the community) response. Advance thanks.
hello, purchased the Rinnai RUC98in and my existing natural gas line that is plumb inside of wall, to old water heater is 1/2", should I get a 1/2" to 3/4" connector and run 3/4" to the unit, and possibly lose some gas pressure psi, or just run the 1'2" gas line?
Don Smith go with the 3/4” line to the tankless. We use a 3/4”x1/2” ell and a nipple or a piece of pipe depending on how far the gas is from The tankless. Hope that is helpful Mike
Don’t know which way to go. Indoors or outdoors... Got a Bradford White hot water heater I hate indoors. Need the space and want to lower gas bill. I’m confused now. For indoors I believe I’d need another plug outlet 🤨 So that’s not gonna work. House is already maxed on volts. Two bathroom home, just hubby and I. Can you suggest a Energy efficient Rinnai possibly! I watched and subscribe to your channel. Great info.
I would go with a RL7.5E that’s the external model. you will still need a plug for the inside or outside model but you only need a 15 amp breaker to run the Rinnai. You could share an outlet to operate the tankless. I hope this helped Mike
very fine explanation and good work, could you please how to get practice or knowledge from Rinnai to fix of the part and maintenance of the product. I still work as a plumber but I need more practice I live in Australia. I Still study as a plumber in the TAFE, but the Teacher doesn't know too much. thank you very much. for you show how to install.
this country needs more people like you who are straight up and honest!!!
I emailed Mike about my Rinnai issue. Very soon after, we spoke over the phone. I can't say enough what a kind and intelligent person this guy is. Thanks for all your help!
One of the Best Instructional Videos Ever! Clear, tight, concise. Information in every sentence. No wasted time. Right to the point with accurate info. You could teach in a Vo-Tech School. Thanks.
Thanks again for your advice ! I swapped out an old unit that had a leaking heat exchanger for a whole new, identical unit. All the plumbing and vent lined up without much problem. Hot water again! For those of you out there who are contemplating work on a rinnai ....listen to Mike ! He really knows what he's talking about.
I will be installing my first Rinnai in a month. I may need to call you to discuss whether or not I will need a PRV. Thank you for these videos man, they are priceless. You are doing God's work for plumbers.
As Jay Leno says, “there is always a guy who knows it like none other.” You are the Rinnai. We just installed our exterior unit. Best videos on tankless. Also love your shop! Thank you video on my channel!
Wow why thank you very much.
I just completed my RUC98i install in Michigan. I could not have finished without Mike as a resource. I called him 4 times over the weekend and he could not have been nicer or more helpful, especially since there was nothing in it for him. Rinnai should be thankful to have an dealer/installer like Mike. After Mike clued me into the aggravating hidden mixer valves in my master bath (no more daily complaints from wife about bath water temp), the unit is running great. Even with very cold incoming Michigan water, it is cranking out 130 degrees no problem.
Great Instructional! I love this guy. I'm a 30+ year gas tech. Never put in a Tankless. Your videos are going to be priceless. Thank you.
Mike, thank you so much for taking time on a Sunday night to call someone 2000+ miles away! We appreciated your troubleshooting our lack of power on our Rinnai propane water heater. It was great talking with you. You are definitely an expert on Rinnai!
This guy is awesome.
I needed several answers regarding my Rinnai tankless install. I am not even in his area and he still took the time to talk. If it wasn’t for Mike my local installer would have made a few poor choices when installing my Rinnai. Thanks to Mike several counties over....I had a good install.
Thanks Mike!!!!!!!!!
I guess Im kinda randomly asking but does anyone know a good website to watch newly released series online ?
@Chase Tommy lately I have been using FlixZone. You can find it on google :)
Thanks Mike. I have a Rinnai unit in my house, been operating flawlessly foe 16 years. I clean it with a pump, a couple of buckets and vinegar. When I need a new unit it will be a Rinnai. Excellent video(s), keep up the great work!
Bob Colorado wow that’s great! I tell all my customers if you take care of the tankless it will last 20 years. I will forward your comment to the Rinnai Rep. I glad to hear it’s working good for you. Could you send me the model number and the state you live in. Mike
First let me thank you for answering my call, and giving me the information I needed. I will continue to watch your videos, and try to learn as mush as I can. You are a very good teacher. Thank you once again for your training.
The Rinnai Guy is the Man to watch! Clear, precise, and extremely informative. He even utilized his personal time to return my call and personally assist me with my questions that I posted to RUclips. Pleasant man to speak to. Thanks again Mike. Your help is truly appreciated.
This guy is frikkin AMAZING!! I had some questions about installing a V65i on my converted skoolie and he called me and helped me out! makes the internet worthwhile. Am going to post pictures when I'm done - THANKS MIKE!
I'm so glad that I found this. Other than contractors that hate DIY home owners (including my electrician brother some of the time) I don't see why anyone would give this video a thumbs down.
I was trying to decide which brand of tankless water heater to buy with the Rinnai definitely up in the running. I will go with the Rinnai mainly because of your videos and clear explanations. You have removed any reservations I had and answered any questions I have (and probably many I would have had).
I have a 1100 square foot house (built around 1945) in Michigan with one bathroom, kitchen sink, washing machine and laundry tub with a (new) well for a water source. This used to be our summer cottage and now a full time home. It's a small house but being I traded square footage for lake frontage it's what I have. There is just my wife and I now so there is no big drain (pun intended) on the water system so I figure that a 6.5 GPM 150K BTU system should work out fine. My one significant concern is the well water quality but being I am also doing a major upgrade on the water filtration system (which will probably include a poly-phosphate filter) I don't think it will be that much of a problem as long as I do the maintenance on the tankless.
My current project is replacing the mix of copper, galvanized and PVC plumbing with PEX and moving all plumbing mechanicals into a small utility room that also contains my force air furnace. I only decided to move everything into the furnace utility room because of the space saving feature of a tankless water heater. So being the current water tank is 14 years old and won't fit comfortably in this utility room and to me a tankless water heater is a 'no-brainer' it is the path I am going on. I would add that I am doing much of the plumbing work in an 18 inch high encapsulated (previous project) crawl space.
I think I will be going with the Rinnai V65iN. I would go with the Energy Star rated top line model however Rinnai 'mandates' that it ONLY be installed by a licensed professional or the warranty will be voided. With the Value line it is only 'recommended' to have a professional install it and there is no mention in the warranty that it would be voided if not using a pro. The price difference between the two would be slightly offset by the $100 rebate ONLY for an Energy Star rated water heater. Personally I can't understand why warranty is voided if a pro doesn't install the luxury Energy Star line but not the Value line.
Over the last forty years I have probably installed over twenty standard water heaters not to mention done ALL maintenance and renovation on any house I have owned for personal use or rentals including two that I built from the ground up. I always go by code and don't cut corners but I have done a LOT of cussing dealing with work that previous owners have done far to many times to count. On the few occasion that I have missed meeting code on anything the building inspectors always point it out and have me correct it. The inspectors have always been fairly strict with home owners over pros and I have learned that it is NEVER a good idea to argue with an inspector - even when they are wrong. I have had follow-up inspectors tell me that I did NOT have to make a change because the work was actually up to code before hand. It's not uncommon for building inspectors to disagree with what is code. But again it is not worth it to argue.
So after reading my very long winded comment I would appreciate it if you have any comments or suggestions. Thanks!
Huge help brother. I know you must get a lot of calls and I truly appreciate you taken the call and helping us out! You answered questions for us that even tech support couldn’t.
Thanks again!
Super guy! Emailed him a question this morning and got a reply around noon! He told me to call after 6 pm if I had any more questions. I called and he discussed the issue completely and offered more help, if needed. Very knowledgeable. I am extremely impressed!
Wanted to thank you for this amazing video - I was able to buy this unit and install it myself, replacing my tanked water heater, and I couldn't have done it without this video and a couple of your other videos. My RL94iN has worked for over a year now with heavy use without even a single issue, and I give you all the credit for this. The detail you go into was just priceless and right on every time.
The RL94IN has wifi?? To be honest i want it as basic as it comes. I dont need extra shit on my wifi
@@humblebragger500 at the time I purchased it, it did not come with wifi - I think they sell a few compatible kits that add on this and other capabilities.
Mike, good job on explaining the basics of a tankless water heater. This is much needed, I find many plumbers shy away from installing tankless heaters because they don't understand them, or they have had a bad experience with one when they first became available in the United States. I'm looking forward to future videos and will be telling folks to check out your channel.
R. Dowden thank you very much, that's why I started this channel. I too had very bad experiences with tankless heaters when my business was in NY. When we moved to Florida I researched and tried out Rinnai and never looked back. Thanks for the comment Mike
First off, I want thank you so very much for your videos. They are awesome and gave me the confidence to tackle my installation after several attempts at getting a pro to do it (either they never replied or gave me a $5k+ estimate). We were without hot water for two weeks! It took me several days doing it alone, but I took my time, especially with the venting. Unit works great 👍. We have hot water 🙏🏻😁 Also, thank you for answering my questions via email! I seriously could not have done this install without your help!
I was looking for all the extra part that goes with Rinnia, in this unit that is not included. And I enjoyed your presentation on the Rinnia tankless water heater.
I watch your festool videos! I didn't know you have this plumbing content. I'm so grateful. Thanks for the videos as I'm trying to DIY this
This was an exact replacement for the old one that lasted about 10 years. ruclips.net/user/postUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh The top of my mitigation tube by my roofline was just a 90 elbow which allowed too much debris to fall down into the fan, eventually ruining it. Without this issue, I bet it would have kept running another 10 years. When I replaced this fan, I added an extra elbow joint so the top tube now it does a 180, which should solve that problem. The radon guys around here wanted to charge me a $300 diagnostic fee, then parts/labor (probably close to $600 total). I installed this all by myself in about an hour for the cost of the fan; it would probably be even easier/faster with two people. FYI the manufacturer's warranty greatly differs depending on whether you install it yourself (1 yr warranty) or have a licensed installer do it (10 yrs).
Just ordered a rinnai RU160 and vent kit to install under the house in place of the old tank heater. I'll be watching your videos for awhile, I'm sure. Wish me luck (and thanks for the videos)!
Mike-THANK YOU for answering my email and taking my phone call after your work day to walk me through my attic install. You are a gracious wealth of info. Sei fantastico.
Can I have the email please or phone number????
Mike thanks for answering all of my questions regarding how best to vent a tank less condensing water heater in my basement that needs to vent via my abandoned oil furnace masonry chimney. If you ever get to Seattle, look me up and the coffee or beer is on me!
Frank in Seattle
mike, love your videos. between your videos & reading the installation manual cover to cover (several times), i have no doubt i can install the RU199iN i want and do it just as well as a pro, for about a 1/4 of the cost. however, if i do install myself, Rinnai WILL NOT honor their warranty. "In order for this warranty to apply, it is required that you use a trained and qualified professional who has attended a Rinnai installation training class before installing this water heater." that is straight out of their installation manual. i contacted Rinnai and they confirmed this is 100% true. Not telling you what to do, but maybe you should mention this in your videos. All of the confidence i have gained to DYI this unit almost made me make a $2000+ mistake. it's a machine, things will go wrong, and Rinnai would not have covered the repairs. because of this, i have no choice but to install a Rheem. i can replace the Rheem 4 times for what it would cost for me to have someone else install a Rinnai just once. still, your videos have been a HUGE help. thank you!
Call me at 19042385349 tomorrow after 5pm eastern time before you do anything and I will go over it with you.
Mike
Thank you for the detailed description of the connection for the venting.
Glad it was helpful!
The Cold Water Inlet must be 3/4 Inch MNPT and Hot Water Outlet: 3/4 Inch MNPT? or I could connect to a 1/2 Inch line with a 3/4 adapter fitting?
Liviu Vasilică try to go as far back with the 3/4” as you can
Thank you. This was very helpful. A different video mentioned the exhaust / intake as concentric; I had no clue what they were talking about except that I "assumed" (correctly). You went out of your way to describe the exhaust/intake vent kit. Very helpful.
More and more people are going this way to save money and not waste ... ideal ... and even so equipment is getting more and more efficient. The only issue is the cost of installation; pricey up here in the northeast.
Thanks so much for posting this Mike. My son is going to get a tankless water heater very soon. This video as well as your "installation" video are very helpful! Bob in Virginia
Bob Troxell he will not regret it. The new Rinnai units are so very well made and if maintained every year will last 20 years. Thanks for the comment Mike
Mike was great! He spend a long time on the phone with my husband and I on how to install the tankless water heater. Very informative. Thanks Mike
Just a fyi if you cut 3 inches off the plastic you still cut 3 inches off the stainless. It starts 1/2 inch longer so you take the same amount off each and its still half inch longer
Thanks Rinnai Guy! You just saved me money, and time. I have been fretting over how I was going to run this 3/4 inch pipe which I would have run off a capped 3/4" Tee coming off of an 1" pipe approx. 10ft away. Especially when I have a 1/2 inch pipe approx. 2 feet away from where I need to install my RL94I. I will used a Tee to increase that line to a 3/4" directly to the Rinnai as you said at 14:02 in the video. Oh yeah Mike, This statement is also a request for confirmation if I should proceed with this plan as I suggested.. Thanks for you knowledge. Looking forward to your reply. Thank you.
I have to get back to work but I wanted to say, this is an Excellent Video, Thank You Very Much, You are an Excellent Speaker and I am going to subscribe. I am putting a Rennai 199 Hot water heater, pulling my own permits after our gas company wanted to charge me $4000 dollars to install. Thank You, Robert
Tilting the vent to drain the condensation outside is a great idea for places in a warmer climate. The manual says tilted back so that the condensate comes inside. I believe the reasoning is that you could build up a giant stalagmite of ice and clog the vent
Hi , I’m hoping you check in often! I live in Belmont Maine in a Log Cabin that we purchased in 2021 , I would like to upgrade to a Tankless hot water heater. Please Know that this cabin is 100 percent off Grid with Solar and a Windmill and a 12,000 watt generator. With this being said this cabin has everything you need and does not suffer any power issues at all . 4season home with no problem, for 17 yrs by the Previous owner , we So the stand up hot water heater is propane fed , we would like to stay with Propane!! Also when we are not here the cabin is shut down completely!!!!! So the unit would have to have the capability of being shut off and restarted by myself . Just like the existing hot water heater,Gas stove, gas Fridge,we have now. The cabin has plenty of electrical boxes for power source, the unit would be in the concrete basement where the hot water tank is now . The Venting of the hot water tank comes out of the top , turns into a 90’ goes straight for 36’ thru wall to outside with a cap on it . If you could make any Recommendations for this Project ! I would Appreciate it . Thank You
Thanks a bunch for the videos. Am going to be installing the RUR199IP. I've seen some Rinnai diagrams and other videos that include an Expansion Tank. Noticed that your installations do not. Can you please tell me when I should/shouldn't use one with the 199IP? Also, the instructions note that there is an internal check valve in the supplied hot water return fitting, do I need an additional check valve on the return line as you demonstrated? Thanks much
If you have a lawn sprinkler system with a RPZ back flow device I would def install a ex. tank. If not you can if you like it won’t hurt nothing. As far as a check valve on the hot you do not need one. I hope this Mike
@@TheBuddylab Thank you very much for the reply! System going in beginning of March thanks to your videos.
Great video. It was exactly what I needed to answer the questions I had to install mine.
Mike, God bless you for these videos. Truly appreciate it!
Just wanted to publicly thank you for responding to my Hail Mary call last month. We truly appreciate your call, follow-up and are hoping that your reference comes through. Sincere Thanks To You Either Way!! 🙏🏽
Super helpful. I just bought at 7.5i and plan to install myself. This is so helpful - thanks
Great video! I have a question. I am installing a Rinnai non condensing unit. The vent needs to go 3ft to the ceiling and another 12ft horizontally out the side of the house. Do I need a condensate trap if I slope the horizontal section? Thank You!
Thank you Mike !!!
Happy Holidays!!!
SO my only hang up in swapping to tankless would be the venting. Current tank is in the middle of the basement venting out a chimney. It would be a long run (15 FT) of venting to get it to an outside wall.
What happens if my home is ran with half inch copper height no 3/4 should I not put a tankless in and stay with the tank I'm worried about a half inch lines not being sufficient thank you appreciate everything you do
Thanks for your efforts here. I have an 11 year old RL75i that is leaking water from the copper boxes above the box that holds the flame. It still works and heats the water but water is dripping out of the unit. Seems like some crack or something inside? Anyways, I may want to replace the whole thing rather than paying somebody $600-700 to take it apart to try to fix it. I can buy one for $1200. It seems it wouldn't be too much work to switch in a new unit since all the plumbing and venting are in place already. Can I do this myself? Or is ther a lot more to this than I'm thinking?

excellent video thanks - busy installing a rsc199EN after our little takagi blew out after 15 years and this is worth gold! Will def be following up on that vinegar trick, maybe a short detailed video on that showing what u do (filter in/ out etc?). Thanks!
First of all I live in ILL. purchased a Rinnai tankless ( in transit ) tried to locate the gas pressure reg. you use. did not find yet, however all info I came across indicates one is not needed due to it is built in the unit???? With that said MY total system requires at max. cap 359CFH. Gas Co. installed a meter with 10lbs pressure and a cap for 425CFH. I believe a pressure reg. is needed to handle the 10lbs. What you say? Thanks for all that you do. You help a lot of people!
Very knowledgeable , and easy on the ears ... it all makes sense.... Subscribed !
Awesome, thank you!
Finally someone who an explain why...Thanks Mike
If you happen to read this, please link the videos that you reference in the videos in the description
The hot water valve I have won’t screw on to the hot outlet pipe on my Rinnai, model #RUCS65i. I’m use the Rinnai valve kit #MIVK-T-LW. It appears that the hot outlet pipe is ¾” NPT and the valve appears to be ¾” SPT. The cold water valve works fine. It just screws on and seals to the cold inlet. At 13:01 on this video, I’m looking at your hot/cold hookups. On the hot side, I’m seeing what appears to be a bushing between the hot outlet nipple and the hot valve. Can you tell me if I’m seeing this correct and where to get that bushing? I called Rinnai and they couldn’t/wouldn’t help me. I’m not a plumber. Thanks in advance.
Mike I got a brand new V75in Unit. It vibrates when washer is turned on? Any idea of what it could be? It does not vibrate when kitchen/ shower faucets are on? Please advise. Great videos. Watch them all. Thank you.

1961CDAVDABREEZER no problem. Thanks Mike
Great video Mike. Just a quick question. Is there a building code restriction about how far the exhaust termination needs to be from an operable window? What about a roof overhang?
If your in the US it’s one foot from a window three feet from a overhang
Mike you are the best at explaining details thank you 😊 🙏
Excellent video you covered everything i didnt know. Too much trouble . gonna take the unit back and settle for a regular heater
Hi Mike. We have a Rinnai tankless for 7 months. After about 5.8 minutes, the heater shuts down and cold water flows. After sitting for several minutes, hot water will flow again, but for only 5.8 minutes. From what I can observe, the installation was properly done. No error codes come thru. Also, I cleaned the water inlet filter. Any advice would be appreciated. Model RUCS75i. Purchased new from Big Box. Installed by plumber. Vented outside. Concentric? 1 exhaust.
peter borys call me at +19042385349 and I will go over it with you
Is tomorrow after 5pm EAT Michigan, ok with you? I really appreciate your time and experience. Thank you very much.
I had the same issue with my tankless. Turns out my showerhead was getting clogged up with scale. We have hard water in our area. Remove the showerhead and clean the screen. It does the same thing with our faucets. Remove the aerators and clean them out.
Great videos Mike. Because of you I purchased and installed a RL94i around mid March 2019 and it has worked great and would reccomend it to others. But now we have a problem and hate the thought of taking such relatively new unit apart for repair. We have not been home for the last two days so no hot water use. Now the unit is showing an error code eleven when we turn on hot water. After turnning the hot water back off the code clears. I have turned the heater off then on via the key pad, un-plugged the hearter electrical cord, then I removed cover and all looks good. Lastly I removed and inspected the igniter and flame sensors which were clean but wiped them off anyways, reinstalled the assembly and tested for good ingniter spark. But, still code eleven each time we try to use hot water. Next was search RUclips for a fix. I cant beleive the burner is dirty or plugged already. Any suggestion would be appreciated.
New watcher and new subscriber. I've recently purchased a RL94iN. Gathering info for me to install. Thanks for making these videos!
Thanks Mike for the tutorial. Might you know the exact amps and voltage needed for the RL94iP?
Amy Moravec all you need is a 15 amp circuit. It is very important that it’s grounded. Hope this was helpful. Mike
I am replacing my water heater with a tankless rennai. Should I use the indoor or outdoor unit in an exterior water heater closet?
If the shed is water tight you can use an interior unit

Thanks...
Thank you for excellent explain.
It’s necessary at the tankless heaters installation of extension tank for reducing the pressure

Hey Mike thankyou for explaining we have a Rinhnni 160 in the main gas line is hitting the top of the concentric pipe rt below the 90, I'm thinking about hitting in with a heat gun and while pressing a 1 1/2 pipe to mold it . Another question 🤔 it says i need to pitch up 1/4" per foot so only 1/2 " rise. To have exhaust rise out, but did you say point vent down for condensed. Thank Mike ill send a picture if I can Sincerely Dan O'Brien
Thank you Mike. This is probably the most informative video I've seen on RUclips. My question is about how to vent this unit if its on an interior wall? How far can I run the vent stack.

a question. I have a rinnai v94ip and I ordered the vent but it came with the plastic inside pipe (gray color), can I connect it? or do I need the vent with the metal pipe inside. I think mi rinnai is non-condensing. Thanks so much
Henry Salazar you need the vent with the metal inside. The box will day for NON CONDENSING ONLY. I hope this helped.
@@TheBuddylab Thanks so much...
I have purchased a Rinnai V65ip that I'm installing this weekend at my cabin. You mentioned that you have a video of the install from start to finish. I have watched several of your videos, but I can't find that one. Could you guide me to it. Also, I can't find your email you mentioned. Thank you so much for your videos. You have done an amazing job and given me what I need to do this right. Thank you!
Nice Video.
3 Questions:
1-Would you install 2 units (so that both units go on as soon as hot water is needed) I will have 4.5 baths, 3 kitchens, 3 laundries rooms/ between 7/9 adults in the house. Planing on getting 2- v75in
2-Whats the longest Exhost distance to outside allowed?/ Whats the minimum clearance from both exhost (assuming Scenario 1)/ Would unit come with 8'/10' of duct, would i be able to purchase coupling and extra pipe just anywhere, whats the cost?
3-Would my V75in package bring service valves?, If not, Would I be able to purchase them just anywhere?
3-Would you, or your supplier, supply me the Units/ exhost lines, service valves?
Thank you
nat bosco this requires a phone call lol. Call me tomorrow Saturday after 12 pm at 904-238-5349.and we can go over it.

What I’ve been trying find out is does Rinnai make an attachment to cover the intake, the outdoor aspect, screen to cut down on the amount of larger insects from entering the unit? It can be a problem especially during years of a lot of moths or wasps, I think I can design one that won’t interfere with the exhaust. My intake/exhaust pipe is longer than the one shown since it’s about 13 years old. I’ve been looking for such an attachment pretty much everywhere.
Do you have a video of the Rinnai RSC199IN installation
If I have a external closet where my existing tankless lives, do I need to get an external or internal Rinnai unit? Great video !!!!
Can I use cpvc for the hot and cold water lines.How close can cpvc be to heater? Do u have a video showing how to hook up water lines
Great Video! Although asked by another guest I was unable to find a response? Installing a RL75IN in a home with 1/2” plumbing. I can step up the line to 3/4 supplying the unit w cold water and obviously do the same to the line delivering heated water to main 1/2” water line supplying the house. Will this work or do you have to step up more if not all hot water delivery plumbing? Thanks
Considering adding a portable AC to my garage. Is it possible to vent that from my tankless water heater? Example, using a Y vent?
NO it’s has to be a separate vent ONLY
Came across this informative video. I am basically looking for opinion are you able to convert RL94eN to RL94iN ?
Sunday Olufelo no you can’t there’s is nothing available to do that.
Can you please answer how to attach the exhaust vent to the heater unit itself
Hello Mike can you please helping me on making the right decision on what model of Rinnai and the cost of installing. Thank you
Such a fantastic video! I just had one installed yesterday and way too much of the white plastic sleeve was sticking out the side of the house. Looks like a missile hit us! I’ve asked him to trim it back and make it flush...I’m hoping he stands by his work and will do it for us.
Also, how can I be sure that there is a proper pitch for drainage?
Thank you for your videos. Very instructive. Question: Can you cut the concentric vents to shorter lengths? Thank you.
Thomas Yergovich yes you can. You have to cut the outer pipe first and then you need to cut the inner pipe 1/2” longer then the outer pipe. The inner pipe the exhaust goes in 1/2” more then the outer pipe the air intake. I hope this was helpful. Mike
You mentioned 3/4 inch cold water intake as a requirement. My house has 1/2 inch pipes. I plan on installing the Rinnai High Efficiency Plus 7.5 GPM Residential 180,000 BTU Natural Gas Interior Tankless Water Heater. Are the requirements 3/4 inch on that unit as well? Is there a unit that allows 1/2” ? Thanks

What is your install charge to the customer if they buy the RUCS75i tankless water heater?
It would depend on the installation location ( garage, attic etc) but figure around $1,500.00
To $2,000.00
@@TheBuddylab ok thank u!
@@TheBuddylab would that price include removal of old hot water heater?
Thank you for the videos. I am trying to troubleshoot the operation of RL94iN. When opening, then closing a cold valve anywhere in the house, the RL94iN exhaust motor turns on for a second or two. I am told something is wrong. I am the homeowner.
There is something bypassing to make the water servo valve turn for a few seconds. Did you add or repair anything in your plumbing system. You can call me at +19042385349 and I could go over it with you
When installing multiple units utilizing concentric vent pipe. What is the minimum distance horizontally from each exterior wall penetration, between Rannai and furnace concentric venting? And if a dedicated re-circulation vs. cold water return where should the expansion tank be installed? If the cold water return is used with a bypass valve is a external pump needed?
Alan Kunkes the vents should be a minimum of 12” apart. I like them to be 14” apart. The themed tank should be put on the cold water feed. If you have a dedicated recirculating loop and the Rinnai units are the condensing models the pump should be put on the last units cold water line. If you want to call and talk to me e mail you contact info at

Hi Mike, Thank you for the quick response. I very much appreciate it. Yes, I will contact you at some point in the near future with a couple of questions. I have found your videos to be very good and useful. Thanks again.
Hello Mike, I have a 21” vent for the non condensation unit and need to cut it down. Do you cut it down from the elbow end? If so, how do you remove the elbow. Thank you

Scott Lundy thanks
Hi Mike , great videos !!! I have a question , You explained how to do vertical venting through a roof but I'm in a basement and need to do vertical venting and go above the snowline. I'm coming out just above ground level and need to go up. Any advice ?
Jerry L from Philly Great videos Mike Thankyou...installing a rinnai v95in tankless with horizontal exhaust thru the rim joist of a basement ceiling. Horizontal exhaust will terminate about 3 inches off the ground.. I know it should be at least 12 inches. Vertical venting is not an option....any suggestions
Thanks for making these videos, they are great and helpful for DIY community. I am also planning to upgrade to tankless water heater next week. I live in Texas and my unit will be in a closet 2nd floor. My vents are going over the roof. I do not have a luxury to drill a new hole for the new exhaust. I am thinking to use the existing vent for the final 2 feet of the pipe (PVC pipe from the unit to the roof and connecting PCV to the metal pipe 1 to 2 feet below the roof). Also I am planning to use intake pipe ending in attic instead of going out. Attic is huge not sure if it makes difference. If possible, can you please let me know if it is OK to connect to the last two feet of the existing exhaust and leaving intake end in the attic. Appreciate your (any one in the community) response. Advance thanks.
hello, purchased the Rinnai RUC98in and my existing natural gas line that is plumb inside of wall, to old water heater is 1/2", should I get a 1/2" to 3/4" connector and run 3/4" to the unit, and possibly lose some gas pressure psi, or just run the 1'2" gas line?
Don Smith go with the 3/4” line to the tankless. We use a 3/4”x1/2” ell and a nipple or a piece of pipe depending on how far the gas is from The tankless. Hope that is helpful
Mike
Did it work? It helped?
Did it work? It helped?
Don’t know which way to go. Indoors or outdoors... Got a Bradford White hot water heater I hate indoors. Need the space and want to lower gas bill. I’m confused now. For indoors I believe I’d need another plug outlet 🤨 So that’s not gonna work. House is already maxed on volts. Two bathroom home, just hubby and I. Can you suggest a Energy efficient Rinnai possibly! I watched and subscribe to your channel. Great info.
I would go with a RL7.5E that’s the external model. you will still need a plug for the inside or outside model but you only need a 15 amp breaker to run the Rinnai. You could share an outlet to operate the tankless. I hope this helped Mike
very fine explanation and good work, could you please how to get practice or knowledge from Rinnai to fix of the part and maintenance of the product.
I still work as a plumber but I need more practice I live in Australia. I Still study as a plumber in the TAFE, but the Teacher doesn't know too much.
thank you very much. for you show how to install.
