- This video is to help understand the proper type of venting to use when installing a Rinnai tankless water heater.
You can find this venting on Rinnai's website Rinnai.US
If you not a qualified servise installer please find on on Rinnai website.
The vent pipe brand is Ubbink the standard venting with the plastic outer shell and the metal inner shell goes with the series Rinnai
V series all sizes
RL series all sizes
The plastic outer shell and the plastic inner shell goes with there condensing series.
RUCS all sizes
RUC all sizes
RU all sizes
RUR all sizes
With the above series you can double vent it with schedule 40 PVC pipe.
When vertical venting the V and RL series ( Standard Type) you must use a condensate trap off the 1/2" nub on the flue coller.

So I bought a Rinnai L94i and when I looked I noticed the vent was way different than my old Takagi. I watched this video and I sent Mike an email. About 2 hours later I get a call from a 903 area code. ITS MIKE!!!! this dude called me!!! How awesome!! Mike is a fantastic guy, great advice and he walked me through what I needed.... Thank you Mike, From Zac in Houston!!
Love your videos! Takes the stupid out of me. Thanks for making me smarter ❤
Mike The Rinnai Guy
Hi,
I got estimates and interviewed 4 Rinnai pros in order to purchase a tankless water heater. One said that we needed two RU199IN, another said that it wouldn't fit the job , another would only put in the RU199IN not the RUR, and the fourth only puts in RUR and said we would be able to run multiple appliances including the jacuzzi. I also spoke to Rinnai customer support and they were of minimal help.
When I spoke to Mike the Rinnai guy. he answered all our questions and clarified everything. Mike also made suggestions to swap controllers to get timed recirculation instead of wifi to overcome some issues.
Mike gave us the confidence in your product and we sealed the deal the next day. He is a great asset to your company.

Mike yours videos are great,you should be getting paid not only from Rinnai but also from RUclips. I'm impressed with the detailed of each videos you make, appreciated for all your help. Thanks
Thank you, Mike, and your assistant for your outstanding instructional videos. You helped me to understand the value of using the right installation methods and proper components necessary to do the installation correctly. The technique of using cut sheet paper to make a square cut on the tube is a fantastic (and simple) technique. This video is almost 2 1/2 years old and is as relevant now as when it was made. It's no doubt helped dozens, hundreds or thousands of us to get through a tankless water heater installation successfully, and I for one appreciate your having shared your experience via RUclips. For the record, I have only uploaded one video on RUclips, and it was an instructional on how to extract a cylinder sleeve from a tractor engine, so I have some sense of the gratification you must feel for having helped others. Highest regards.
Now that's the way you teach!!
Thank you very much
Mike, Thank You for all the expert advice.
Thanks for the great informative videos you are doing Mike! They are very informative and give us DIY folks the confidence to install these tankless systems in our homes.
Absolutely thorough- and EXACTLY what I needed to do my install.
Thanks
Boy am I glad I found these. Excellent, informative videos, Mike. Great tips and easy to understand. Thank you for helping me with deciding on a Rinnai model and installation recommendations for my basement.
Very, very helpful. Bought an open box briefly installed RUC series missing the vent termination and thimbles. Most of the websites have a single grainy picture and no directions so this was gold to me. Thank you.
Great video!! Extremely helpful. Mike also provide me great direction and suggestion as I am plannning an install!! Thank you Mike!
Wonderfully clear and complete instructions. Thank you! 👍
This is gold, I cant beleive I havnt stumbled across your videos untill now. You are a plethora of tankless knowledge. I really seriously appreciate your videos they have given me a lot of insight on proper tankless installs. Im a plumber of just a hair over 2 years, currently studying to get my P1 license in NC and have been assisting my supervisor on a free class he teaches on all things service plumbing every thursday morning 2 hours before clock in. Feburary has become tankless oriented. All the things you have talked about and explained definitely have been paramount to my level of knowledge on tankless installations and servicing. Once again I very much appreciate your time and willingness to share your expertise. Thank you.
Mike, amazing video thanks! I've been digging around trying to find some more information on the multiple venting options and you explained things very well.
Thanks!! I dont normally install these, we are doing a Reno with an existing rinnai. I was a bit confused what the venting was going to end up looking like/ how it works. This helped clear it all up!
Great video! Very informative. I'm in the process of installing my RUCS75i now. I was going back an forth on what venting to use and this video helped convince me to use the concentric piping. Thank you!
awesome video! very proffesional , straight to the point, easy to understand. thank you.
thanks mike... great guy and great plumber.. this guy no his field... called me up and explained everything to me... way to go thanks again..
Great video, answered ALL of my questions.
Mike, you’re the best! I had a problem with rain getting into my water heater. He emailed back right away, requested photos and then gave me his professional opinion as to the cause. It worked! Thanks, Mike!
What vent for a rinnia RE 140 ip
Thank you for all the info. Very helpful!
Great individual, we need more caring people like Mike, Thanks for all his help.
Extremely helpful. Thank you so much, guys!
thanks you very much Mike for you give some advance about the Vent. I Understand more clear. All the best to you and you family.
Very helpful. Thank you for making the video.
Mike-- Thanks so much for helping me diagnose a leak with my Rinnai tankless water heater over the phone! Also great advice for deciding whether to replace the heat exchanger or just buy a whole new unit. This guy is fantastic!
Thanks! Incredibly helpful! Definitely helps in making a decision about the Rinnai tankless water heaters. Rinnai should pay you! :D
Mike this is another great informative video. Keep it up. Great Job in explaining and showing all venting options.
Hiren Patel thank you very much
Love your videos, man! I love your paper trick for getting a straight cut. Quick tip on cutting the inner pipe, instead of measuring 1/2” out from the outer cut line, measure from the outer edge of the center pipe, and cut the same amount from the inner as you did from the outer. The inner pipe protrusion is set at the ubbink factory, so basically cut the same off the inner as you do off the outer and you’ll always end up with a factory-perfect inner-pipe protrusion. Love your channel!
Very helpful! Great videos. Thanks.
Thanks you for your videos keep up the great work
Very Helpful! Thank you! 🙏👍
Very informative video...just the info I needed...thank you!
Thank you for your videos; This is Great information.
Wow Mike I’ve been able to install my Ru199 confidently because of your completely informative videos. Thanks so much!!!
what is the diameter of the hole needed on the wall for both the vents
Thank you your videos helped me out a lot . I learned so much from your videos. I will be emailing you soon when I get my unit thanks so much mike
Your videos are very informative. Thanks. I wanted to replace 2 50 gallon water heaters with one tankeless but they are not close to outside wall and the exhaust tube are connected thru the chimney thought I can use it for tankeless ventilation but I guess this video changed my plan
Very informative and thanks for taking the to share your professional knowledge.
Great video and information, thank you
Fantastic video.
Very helpful video thank you. Mike what PVC elbows 90 and 45 go withe the red lettering pressure rated pvc ? I’m having a hard time finding them for 3inch pipe
Very nice explanation!!
Thanks for the great video. I was wondering how to get the proper pitch on the pipe when I cut the hole on the outside wall for the tankless. The template supplied with the heather says 5” from top of heater and was wondering if that will give me the 1/4” per foot required.
I did it with B Vent in my Garage Through the roof and it is working like a charm in the past 4 years. A poor family cannot spend another $600 on the termination kit.
Thank you, very informative 👍
great Video and very informative!!!!!!!
Thank you sir ..just what i was looking for
Hi, and thanks for the greatest videos on tankless venting. We just bought a RL94i Rinnai heater. Then purchased the two pipes in your videos: The 18" VERTICAL ROOF DISCHARGE TERMINATION PIPE (SKU# 184118-S) and a 19.5" NON-CONDENSING VENT PIPE EXTENSION (SKU# 224052) both UBBINK. The heater is installed, It is a straight shot from where the heater's vent is through the attic and roof. I think the installers made a big error with the venting...if I look at the section in the attic, I see a gap between the two white poly pipes. Inside is a smaller metal tube that is accordion-like. The plumber then taped around the gap with silver tape. I am sure they did some bad cutting and rigged this pipe, as it is NOT what came with the unit, which was straight and smooth. Assuming they have ruined the piping after watching your video, I went and bought two new pipe (same ones), and think I can do it myself whit the help of your videos and since the ceiling and roof holes are cut.
I assume the bottom of the roof termination pushes directly into the top of the extension (in the attic), even though the top metal (roof) piece protrudes only about 1/4" beyond it's poly.
Thanks again for the five-star videos!!!!!
Mike is the greatest. He emailed then called me to answer my questions. Where do you get that kind of service on youtube? Thanks again
Yup, same with me. This guy is the real deal. Thanks Mike.
poor Michael! Nice videos.
thank you. this was a great explanation and tutorial
You're very welcome!
Hi Mike thanks for the videos they are great. can you tell me when venting a non condensing horizontal through the wall do you leave it stick out from the exterior wall or cut it flush to the outside or ??
Hi Mike, Thank you for these videos, they are excellent and have inspired me to install my RUC98iN myself. I have a couple of questions about the venting that I'm hoping you can help me with. First is, what tool do you use to cut condensing vent pipe (all plastic) to size when needed? Second is how do I calculate the 1/4" per 12" slope required for condensate drainage? I'm in New Jersey and thank you in advance for your help.Tim Shannon
If you remove the metal tube from the plastic you can use a miter saw to cut both pieces individually that is the quickest way to cut both pieces in less than 3 minutes
Hey Mike. Thanks for the video. I was wondering if you have ever used the IPEX Low profile termination kit (196985) with 3" sch40 PVC pipe on the RUC80IN? I used a similar termination on my furnace and I liked the smaller holes through my rim joist and the look on the outside of the house. Any thoughts?
Hello great instruction video on venting. My question is how close can the outside exhaust pipe be near a window. Thank you.
Venting seems to be the biggest problem. The instructions are very vague and the translation into English don't help. Thank you for taking the time to make this video. Very helpful.
herman munster no problem glad it helped
Hi, Mike! Do you know how to solve the Rinnai Rl 75 error code 10 about air intake or exhaust vent? Because there is no hot water. Thank you for your excellent video!
Mike this is great! Is there any advantage to doing concentric venting vs PVC? I thought I’d save some money and do PVC on a 12 foot run. Any thoughts appreciated!
Hi Mike. My furnace is currently direct vented on the same wall I'd like to mount my Rinnai to. I'm uncertain which of the clearance rules i should use when running the vents for the Rinnai. Does the Rinnai exhaust need to be 3 feet above the furnace air intake if within 10ft horizontally? Or just 12 inches apart?
Your videos have been a wealth of information. Thank you for putting them together!
for venting out of masonry wall would you recommend concentric venting or 2 seperate vents
Hi Mike I just purchased a pre-owned RL94i series. The biggest question that I have of course is the Vinton. When I purchased a unit it did have a plastic gray venting pipe the per your instructions it should have the metal concentric venting pipe. The question I have is can I use some schedule 40 PVC pipe to vent the unit through the roof of my house because this will be going in the Attic?
Mike I a question.
We have a vertical vent out of the basement. We have a window pit for the clearance. We have a HVAC unit going in . The pad is covering that area.
Can I put an elbow go up 12 inches with a second elbow.
Just had my rinnai rl 75i non condensing tankless water water heater installed yesterday, works great but the exhaust is too long sticking out to the side , about a foot and a half long, can I cut that and make it shorter?
Hi Mike. I was wondering if you could talk about the clearance requirements for the venting. It's there a clearance requirement above a vent? I'm asking because the wall that we would be venting out of has an overhang.
Your videos are really helpful. However, I couldn't find one that shows how you seal the outside wall while using a concentric vent. My outside wall has flanges and the ring won't lay flush.
Mike, Thanks for video, it helped a great deal. I am replacing an old tank unit with the Rinnai rur160ie, in a walk-in crawl space. There is a pier 9” from the center of the existing vent hole. I am planning to use the concentric venting set up. Can’t I use a 45 degree elbow to give me the additional clearance that I need for this install?
Surfjunkie79 call me on Thursday after 6pm eastern time and I will go over it with you

Mike
I have a question for you. Just installed an R53i Rannai and it works well. I used Rannai concentric vent pipe. Plastic with the metal center. When I plug in the vent pipe which is 4' long total. 90 deg plus an extension through the wall to the outdoors. Now when I turn on the water the heater comes on. But, quite often the burner starts then the unit rumbles the flame turns orange but will go back to a blue flame??? So, I just put the 90 deg on the unit to see what happens. It still does the same??? I can't figure out why??? Without the 90 deg the unit seems to work all the time.
Mike in reference to the V series and the RL series what about rolling a 360 degree pee trap coming off of the 5/8 npt nipple leading to the condensate trap??? Should that be done?
Does the Rinaii CU199IN require the 2"/4" or 3"/5" Concentric Vent for horizontal venting less than 4 foot long? Thanks
For anyone with a long vent going straight up or up and then out, you may hear a loud noise due to the way long vents change the air mixture for the rinnai. First you gotta make sure you have plenty of gas available at the tankless, I had to install a bigger regulator (maxitrol 325-5L nat gas replaced old 325-3L). Then I had to tune the high and low burn mixtures. Check your manual but for me I had to turn on a bath tub full hot (triggers the loud noises), open the front, flip dip switch 8 on the top switches to put it in mixture tuning mode, hold down button B For 1 sec to put it in high burn tuning mode (starts flashing a small red light, the two black buttons are A and B). And used A and B to tune the mixture pressure, I turned it down (B) about 5 or 6 presses until the noise stopped. If I pressed it anymore the noise would return, and I could see the flame going out in the window, so I turned it back up a couple pushes until it was nice and quiet. According to documentation you should do this with a manometer attached and tune it to about 2.6"WC (from factory it comes around 2.8"WC high burn) however after playing with it, I had to turn mine down quite a bit more to about 2.3"WC to get rid of the loud flameout noise when mine was warming up for a high flow, like a bathtub. finally flipped off switch 8 and it was fixed. You can also tune it for low burn by following same process but holding button A for 1 second until you see red light. This might help with noises heard when first opening a small faucet tap. According to the documentation, it needs to be lower pressure high burn the longer your vent is. They really should make this more emphasized because I read so many comments complaining about the noises and lots of people just returned their rinnai tankless units rather than mess with it. Mike's a good guy he helped me test some things including tightening up all the vent pieces but ultimate fix was this high and low burn tuning process which my plumber did not know anything about. The documents are really poorly organized on the rinnai website with dumb file names but if you lookup your model on the website and click through the attachments you should find a file that has instructions for this process. Good luck! Hope this helps someone like me who had it all installed but was pulling my hair out with that loud noise when running a bath.
Not sure how to get a hold of you but we are putting in one our self the only question we are how far apart does it have to be from another intake or exhaust on the same wall outside
What sealant is used on the thimbles and where is it applied?
Hello, do you have any videos on how to align the vent pipe to get a strait shot to the outside? I only need about 14” of pipe to pop outside. Also for a 5” pipe what size hole.
Thanks
What about wall venting for condensation trap do you have to have it
can I run the schedule 40 PVC into schedule b after a long run. I have the upgraded unit with the separate intske. I Would like to avoid cutting into the roof.
Hi.
I have a Rinnai RL94 tankless with exhaust iced up from the horizontal pipe. Do you know where I can buy an extension?
Swim should use 3” schd 40 pvc only? Or can Swim use 2”?
I have a Rinnai V65i. I found a bunch of mud daubers nesting inside the vent from the outside wall. They are preventing cold air from coming in which in turn prevents hot water. I can't figure out how to take that black cap off so I can scrape the nests out, any ideas on how to do so? Should I take the pipe off of the water heater and pull the entire ventilation system off to scrape them off and then blow the debris out? Then after reinstall everything?
When venting the intake and exhaust from a basement (newer Rannai tanks) with 2" Sch 40 PVC , is there a limit to how high up the elbow is above the unit and can there be more than 1 elbow on the exhaust in case you cannot directly go straight up with the venting because of HVAC unit outside ??
I’m needing to go 13 foot to get out of my roof with a v94i but they don’t make a vent that long. Do the extension connect together like can I buy 4 extension and get out the roof
Mike, very helpful. Any tips on venting through a garage that is stick built with full size brick gender on the exterior?
Veneer not gender. Darn auto correct.
Eric Beach we would chop through the brick to wall vent it. Use the black thimble to mark the hole and drill small holes on the outside of the line then chop the center out.
Does the vent tube have to be 1 inch away from combustibles just like b vent?
How do I tell if my unit is a condensing or non-condensing unit. I am adding the snorkel exhaust to an existing unit. It is a Rinnai R75LS.
Hey Mike, Thanks for all the informative videos! I have three questions:
Background:
Previous homeowner installed a Jacuzzi non-condensing tankless indoors. Ran concentric Ubbink venting with a few 90s and 45s over 10-12 feet to a horizontal exit.
1. Is it ok if the installer kept the air intake portion of the termination INSIDE the house? (The larger black portion of the terminate with the intake vent is inside while the 3 inch exhaust is the only thing exiting the house.)
2. Installer did not orient the vent to slope away from unit but instead it’s about 2-3 degrees slopped back down to unit.
3. There is a black nipple at the base of the concentric venting but there is no condensate tube/tank being used, should I get one and install it?
Happy to chat if you’re willing and thank you so much for being so giving of your time!
Call me at +19042385349 today around 4pm eastern time and I will go over it with you Mike
@@TheBuddylab will do!! Thanks!
helpful!!!
I currently have a RL94IN but want to upgrade to a RU199IN since I need the additional flow it delivers to feed my hot water pressure washer. The pressure washer needs 4.5 GPM and the RL94IN won’t keep up at a 70 degree temperature rise. My question is, can I use my existing Ubbink non-condensing vent on the new condensing unit? Thanks in advance
JSEDecker no unfortunately you have to change the vent to the condensing one. It’s the same size the difference is the inner core is plastic. One other point make sure you connect the condensate drain from the unit to a proper drain. Thanks Mike
Mike please help what happens if I use a condensor elbow and tube? On a Rinnai v65ip?
Will Rinnai fittings and piping work with AO Smith 310c tankless water heater? It’s the exact same 3”X5” connector on the unit.
David Jimenez it should Ubink is a separate company that makes venting for different Heaters. Rinnai just approves them for use. Just make sure your using the rite tape for condensing or non condensing.
I installed a 1 foot condensing vent on my RU series and now I see wasps entering the intake . What is best way to stop this before a problem is created. I see about 15 or so wasps inside so far.
so for the rl94 I cannot use pvc?
Mike, I have a couple of questions, that I hope you can answer. I have a Rinnai RUC98iN installed in my attic. My question is on the condensate drain line...the plumber that installed the unit ran a piece of nylon tubing from the condensate drain line to my pan overflow drain (PVC) that drains to the outside of my house. I have my A/C condensate line running right beside it that drains into a bathroom sink drain line. Can I "T" into the A/C condensate drain that goes into the sink drain line with my Rinnai condensate drain line, too? The reason I ask is, when it freezes outside my Rinnai condensate drain line freezes too, giving me a error code 25. Unfortunately, there are no drain lines in my attic. Thank you, great videos, BTW!!
DJ Sco yes you can it’s not the best application to do buts it’s better then it freezing up. Just make sure that the pvc drain line stays clear at all times. If you can run a separate line to the sink it would be best. I hope that this was helpful. Mike
OK, thanks for the quick reply! Will the condensate (acid) mess with the Sink Drain Line which is PVC, long term? i.e. eating away the pipe?
DJ Sco no it won’t
Mike is great guy. I have took so many advise from him. DJ Sco the condensate is acidic but it won't affect PVC pipes (if there is copper line for the drain like in some old construction then you have to worry). Follow Mike's advice you won't have any troble.
Mike thanks for making these videos. I have really enjoyed them. I have one question I accidentally ordered the wrong exhaust vent for my noncondensing unit. Rl75i. Can I use the condensing vent until the correct one comes in? It will be here by Friday.
nielsengabe unfortunately no the exhaust will melt the center and clog the top of the heat exchanger. That will cause you a lot of trouble. Temperatures can reach around 300 degrees. Can you call a local Rinnai supply house to see if they have it.
Mikes wood shop unfortunately there isn’t one close. I think I know the answer but can I run it temporarily without the flue?
nielsengabe e mail me your phone number and I will call you with an idea.
Economyplmbg@aol. Com
Mikes wood shop thanks for the help. You really helped me out of a tough spot. I appreciate your taking the time out of your day to talk to me and answer my questions. Keep up the awesome work.
How far away does the vent have to be away from windows and doors?
I have a R75LSi. There is nothing connected to the plug on the top of my unit. I believe it is the condensate drain. it's plugged. Is the condensate drain necessary?
Alejandro Leyva if the vent is the standard horizontal vent which is a elbow on top of the unit and the vent pipe through the wall you don’t need the condensate drain connected. If there’s a lot of horizontal vent piping or the vent is going through the roof you need a condensate drain.
Hello,
Great video can you tell me where to get the the lower enclosure to cover the pipes. The RX199IN is going to be installed on the outside of a brick hose. On lowes web site is picture with it installed but i can seem to find how to purchase. Got the top cap on order as well.
Thanks
David
You can buy it from Rinnai direct or I think Amazon sells it
@@ThatTanklessGuy They referred me to Ferguson got it.
How far below a non-vented soffit of a garage does a Rinnai concentric (horizontal) vent need to be installed?? The manual doesn't give anything. 12" ??
Hey Mike, serious question here; What would happen if the condensate trap lost it's prime (the water that you added dries out)? Bob in Virginia.
Bob Troxell it may refill as the unit works but that’s a slim chance. You would have to refill it. Hope that was helpful Mike
Thanks Mike! I'll have to go over and check on my son's Rinnai venting and condensation trap. They have used the heck out of the system since it was installed and he and his wife both love the Rinnai! Thanks for these videos. They are most appreciated. Bob from Virginia.
Can I trim the horizontal exit pipe so that it is not sticking out so far from outside of house?.
Also I will be coming out to a brick exterior.. How would I seal that properly around the pipe because that black seal won't seal properly
Cutting a round hole in your brick exterior can be done with a wet core drill but it is expensive and messy and the large diameter (140mm or 5.25") is pretty dam expensive and the rig is pretty heavy to hold horizontally for any length of time. Rental yard is best bet to drill that hole cleanly. OR you could try to do it with a Morse carbide tipped hole saw. They are around $55 dollars each and can be run in a slow rpm drill, even some bigger slow speed cordless drills. You can use an acrylic sealant around the white PP plastic, perhaps roughen up the exterior with coarse sandpaper to increase adhesion. The spray foam polyurethane sealants do stick to plastic but have poor UV resistance over time. They expand greatly and may have to be cut back with a knife after curing hard to get a clean appearence. Use the black plastic trim piece to cover up the UV sensitive white plastic PP pipe and sealants.
You only need a couple of inches on the exterior termination unless you have an interference with a window, soffit or some other vents including dryer vents that will require you to have a greater penetration. There is a ton of info in the Rinnai manual on vent clearances and no go zones due to windows, doors and existing vents
