Rinnai's Ubbink venting the difference between condensing and non condensing piping

- Well here is the video you all have been asking fore LOL No its the number one question I get asked what vent to use and what vent not to use.
When I train plumbers on Rinnai heaters I tell the the first rule of thumb with venting if its metal its wrong period.
An easy way to remember what vent to use it if its non condensing like a V or a RL series its metal inside.
Condensing like a RU or a RUR its plastic inside.
NEVER USE THE METAL b VENT OR FLUE PIPE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The advantage with the RU and The RUR series unites (Sensei) is you could also vent it with schedule 40 ( Red letter) PVC piping.
I hope this will answer a lot of questions on what to use and what not to use when venting a Rinnai tankless heater.

Mr. Mike
I listened to your Spotify podcast, wow what an interesting story! It is awesome that you are helping people around the world. We need more people like you to educate people!!
I appreciate your responses to my emails and our phone conversations have helped me better understand my tankless water heater project.
Thanks Mike
Hey Mike. Excellent videos. I am repositioning the Rinnai that came with my house to a different room. Very helpful information.
Great videos Mike! Thank you very much for taking the time to answer my questions!
Hey Mike - again, you saved me a lot of aggravation. While waiting for help at Lowes the other day, I was wondering about using metal duct. Luckily, 2" PVC is working fine. Thank you for all of your help on e-mails and the phone - my new i120C is up and running. Although I have a lot of fine-tuning to still do.
Now if I could just get that darn Control R v2.0 software to work, I'd be golden!
Great video, Amazing guy! Thanks Mike! I’ll keep you posted on my install
DeJuan from GA. Thanks Mike. Will keep you posted on the vertical install.
10:43 - Great videos and knowledge. Thanks for not editing that out.... it made the video even better to watch :P
thanks for the comment, I edit nothing out I shoot it and download it if it happens so be it. Thanks Mike
Hi, Mike!
Thanks so much for all your very informative videos concerning Rinnai maintenance procedures. You have greatly helped me to get out of my comfort zone which was electric or gas tank-style water heaters and become more comfortable with operation & maintenance of gas tankless heaters. I have been doing all the maintenance on my 4-year-old V65i and just recently removed the Fan to check for debris - currently having no problems. To my amazement it was clean & shiny as were the plenum and Burner inlet orifice plate. My Ubbink ducting is about a 10 foot long horizontal run to an outside wall in the garage (professionally installed). So, I was wondering where all the debris must be collecting and noticed a video where you showed the top view of the Heater with concentric duct removed exposing several small holes in the fresh air intake plate. I would like to check for debris but can't get the Duct out all the way - outer plastic duct easily pulls up about an inch but the inner metal duct then seems to be hanging up. Can you provide any tips on what techniques I should use to access those intake holes? Thank you so much.
Mike,
I've enjoyed your videos, great resource even for homeowner who is having installation done by others. I'm getting two RU199in units and due to location will be going with 1 - common intake and 1- common vent so two pipes going through the exterior wall. After the header, it is a short run to the outside about 5 feet with some elbows. Spec sheet says can use 3", would you use 3" or bump to 4"? I do intend to put some sort of rodent barrier in the outside 45 degree elbow.
Great video and advice. Do you have a video that shows strictly using the 2 inch piping system for venting?
my horizontal exhaust/intake will exit the exterior wall about 9 feet above (almost directly above) the outside ac unit. Do you think the air from the fan of the AC unit will cause issues forcing air into the exhaust outlet? My only other option is remove old B-pipe and go out the roof BUT this will be a much more difficult installation. Thanks for your time Mike I really appreciate your videos and wealth of knowledge that you so willing share.
Nice 👍
hi Mike, you are a great guy, thank you so much for your informative videos. I watched a lot of your videos about Rinnai tankless water heater. I am going to install a V65iN. According to Rinnai technical parts list, I have ordered concentric vents (metal) which is metal inside and metal outside. After watching this video, I am wondering those metal vents (metal inside and metal outside) are suitable for V65iN or not ?! Can you give me some comments? Thank you so much, have a great day!
Hi Mike, thank you for this information. Turns out I was about to purchase the wrong type of pipe. Would you be able to post the Part numbers for the condensing Ubbink pipes?
Hi Mike - Great videos!!!! In this video you talk about another video where you show us how to create a template to cut an existing metal roof jack to fit a vertical concentric condensing Ubbink exhaust termination. But I can't seem to locate it on your RUclips Channel. Can you please provide a link. Note: I sent you an e-mail too with my phone number. Thanks for all the super videos!!!
I have a tank water heater in a bedroom in my basement. It’s in a closet. The tank has gone out and I want to replace it with a tankless. It’s a long way to the roof. I want a condensing unit. Can I run the duel pipe until I get to the attic, then use a single PVC pipe to the outside on the roof?
Mike, for a Non-condensing RL75i, can I vent into a garage and then extend the exhaust pipe only to an outside release point? Using Schedule 40 to extend just the exhaust portion of the pipe?
Thanks.
My problem with horizontal vent coming out strait is that i am going to install the unit in my crawl space wich is at 4 feet high them when people walks near by the pipe will be caught by the exhaust gases . my question is this if i can install a ninety the grees elbow and turn it up has if is a roof vent thank you.
Hi Mike,
I'm have a horizontal exhaust tankless. It's about 9 years old. I recently started getting a small amount leaking from the white thimble. It is a very small amout but has sticky yellow consistentency. Would you be able to give your opinion?
I'm replacing a continuum with a v series v94in natural gas .. both are concentric exhaust..I checked with rannai to find the closest replacement model to what was here.. obviously I'd like a more efficient model but for ease of installation / to use old venting and same gas line etc I decided to just go with the cheaper(400$) model..I know.. not cheaper in the long run .. but I don't have a drain super close either. My question is on the concentric exhaust.. how is it attached to the water heater? Is there any adhesive used..a gasket etc? The old unit is leaking and works once a day when I turn the water on to it.. it's 20 years old so I'm not just having it repaired.. is that a sound judgement in your experience?
Great video, but now I'm confused. I have an old Rinnai condensing RC80HPi installed since 2011. It has a single white plastic (PVC?) 90 degree elbow between it and the wall it is mounted on, so I assume it's a concentric pipe. I'm replacing it with a newer condensing Rinnai and everyone is telling me I can't reuse that pipe and I need to use 2 separate PVC pipes? Sounds to me from your video I can actually reuse it and leave the second 2" pipe capped?
Can i use Rinnai venting for the A.O. Smith tankless water heater venting?
Hi Mike - any idea why my Rinnai tankless get CODE 79 every time we get heavy rain in the area? I am getting water leak through the vertical roof vent into the water heater as I see it dripping. Do you see anything wrong with the way I have it installed? I have pictures that I can share showing the installed vent, if that helps. Thank you in advance
Curious about venting replacing old r53 with rl75 vent is different is there a retrofit kit to adapt or do i need to replace entire vent
Hi Rinnai Guy! Thanks for the Videos, I have a question about my Riannai. I have a RUR199iN that was installed in my garage and vented vertical through our roof and takes in fresh air via the garage area. The installer used 2 inch PVC all the way through the roof and looks like a candy cane coming out of our roof. Does this sound like a sufficient vent solution, or should we install one of the Rinnai Condensing termination roof kits as shown in your video?
sorry for the delayed response yes that sounds good as long as he sealed the roof penetration good. mike
Since the venting install is the same for condensing and non condensing units (assuming you are concentric venting) why do plumbers always recommend condensing units? It’s just more work to install the condensate line.
I am replacing my Rinnai Tankless Water Heater (non-condensing) with a new condensing unit. We live at 4300ft in central Oregon and have cold weather to deal with in the winter. Since I already have the non-condensing venting installed through the ceiling and out the side of our log house. Can I use the existing venting? I am going to vent the intake from the heated garage. Don't know if it makes a difference but the garage has an electric furnace and stays around 60-65 degrees even in the coldest winter days. I have ordered a new Rinnai RU199iP Condensing Tankless Hot Water Heater, 11 GPM, Propane, Indoor Installation to replace our old C85 unit that gave out after 18years.
Did u ever find out if you could your existing non condensing pipe?
Hello, RUR199IN, concentric venting, straight up 8 feet, then horizonally out wall 21 inches. Do I need any sort of condensate collector in the venting?
No it will drain through the internal condensate trap.
Mike, I'm installing a V65ip this weekend. My engineer told be because of the extreme cold weather where I'm installing this water heater, I need to have my horizontal vent pipe slope to the unit not down and out. So, I have ordered the Vent kit with the plastic outside and the metal inside. That metal inside is ok for condensate?
Hey, did you figure this out? I’m installing a v65ip in a cabin and am unclear whether I need to use a condensate collector or not. I’m just doing a straight short horizontal vent through the wall. live in Ontario canada so definitely very cold winters!
@@AylaFenton I did order the vent piping from Rinnai which has exhaust and intake piping in one. I slightly slipped it towards the water heater. There is a condensate connection on the top of the water heater where I’ve connected a flexible tubing with a loop in the tubing to act as a trap. This has worked great for me, but I have a floor drain in that utility closet to allow the condensate to drain. Hope this helps
Can I use the existing 3" galvanized steel vent pipe termination and run the two inch PVC up through this existing vent pipe, so it is surrounded by the metal pipe?
Yes you can just make sure when you end it the two pipes are at least 12” apart
Does a non condensing unit do any damage right outside where it vents because it’s technically blowing out acidic gasses? (Where as a condensing unit collects this acid to be drained)
No it does not the gas is only 3% that is expelled.
I am wanting to install a Rinnai V65iP into a tiny home. Replacing the existing electric hot water tank. What venting do you reccomend for my application? Will be venting thru the side access panel out at a 90 degree from unit.. There are several choices.

Mike what dose a reu-v2520ffu use? Its old as in 2005 but the vent i purchased fallowing you video won't fit ontop on the water heater.
The manual is very vague.
You need a 224064 vent adaptor it’s around $50.00
@@TheBuddylab ubbink brand? The one they sent me was 223181.
@@TheBuddylab ahhh this is a adapter. Will this adapter work with 223181 on this reu-v2520ffu?
Im mounting my Rinnai RL94 on an interior wall due to existing plumbing, and wanting to go out exterior wall within 2 feet of unit. Is that acceptable?
Yes you can, if your going just up and out the two feet you can. Just remember to install the condensate drain off the top of the unit. Mike
Hi peeps ...does anyone know the "code" for the length of horizontal venting? I may try to run it throughmy garage and out, and if there's any limit to elbows? I may need 3 elbows but not sure
Thanks
What model number is it? If it a RU or RUR model it’s 65 feet of 2” over deduct 6’ per elbow 3’ per45*
Hello I just bought a Rinnai v75ip and I also bought a condensing elbow and pipe Can I use em together? And if I do? What’s the risk?
that vent will melt from the non condensing piping you need the piping with the metal inside only.
Hello.I need help! I have a rinnai tankless
All my sinks getting hot water without problems.the problem is that water from my ello allo shower tower will not stay hot. THE TANKLESS KEEPS shutting down when the shower is running.my tankless unit is new and I have no problem with the faucets in kitchen or the vanity sink.i have good pressure in the shower.can anyone help
Same problem here. I get a code 12 when I run the tub or shower faucets. I just learned that I have a venting issue by watching this video. I'm hoping fixing the vent will solve my problems.
still building new hampshire
i don't think my plumber knows what he is doing. i have the Rinnai V65IN model and he has 2 PVS pipes rough plumbed straight up through the roof. but they both are connected together just before going through the roof. none of the pipes are concentric.
