- 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.

If you have any questions or need technical help please e mail me your contact info at economyplmbg@aol.com
I will need the model number, fuel type, how old it is, where its located and any pictures of the install
I hope you enjoy this video.

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!!
Absolutely thorough- and EXACTLY what I needed to do my install.
Thanks
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.
Regards

Now that's the way you teach!!
Thank you very much
Love your videos! Takes the stupid out of me. Thanks for making me smarter ❤
Mike yours videos are great,you should be getting paid not only from Rinnai but also from UA-cam. I'm impressed with the detailed of each videos you make, appreciated for all your help. Thanks
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.
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 UA-cam. For the record, I have only uploaded one video on UA-cam, 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.
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
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.
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
Great individual, we need more caring people like Mike, Thanks for all his help.
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
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.
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..
Wonderfully clear and complete instructions. Thank you! 👍
awesome video! very proffesional , straight to the point, easy to understand. thank you.
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.
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.
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!
Mike, Thank You for all the expert advice.
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
Great video, answered ALL of my questions.
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.
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!!!!!
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!
Great video!! Extremely helpful. Mike also provide me great direction and suggestion as I am plannning an install!! Thank you Mike!
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.
Extremely helpful. Thank you so much, guys!
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
thank you. this was a great explanation and tutorial
You're very welcome!
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
Very informative and thanks for taking the to share your professional knowledge.
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.
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.
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!
Thank you for all the info. Very helpful!
Hello great instruction video on venting. My question is how close can the outside exhaust pipe be near a window. Thank you.
Very informative video...just the info I needed...thank you!
Thank you for your videos; This is Great information.
Thank you sir ..just what i was looking for
Very helpful! Great videos. Thanks.
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!
Nice Job!!
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
Great video and information, thank you
Thank you, very informative 👍
Thanks you for your videos keep up the great work
Fantastic video.
Very nice explanation!!
Very Helpful! Thank you! 🙏👍
great Video and very informative!!!!!!!
poor Michael! Nice videos.
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.
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
You guys get issues with ice buildup in winter time on these my systems seems to need a lot of clearing seems like a rubbish concept unless there’s something else causing it ( exhaust, intake single pipe )
Hi.
I have a Rinnai RL94 tankless with exhaust iced up from the horizontal pipe. Do you know where I can buy an extension?
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?
Does the Rinaii CU199IN require the 2"/4" or 3"/5" Concentric Vent for horizontal venting less than 4 foot long? Thanks
for venting out of masonry wall would you recommend concentric venting or 2 seperate vents
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.
Mike thanks for that video on venting properly a Rinnai tankless water heater. So, I’m in the market for a tankless and I had a guy give me a quote for the Rinnai Sensei RU160iN. He came by my home and took a look at my old 50 gallon heater. He talked about how he would install it and then said he would use my existing chimney metal vent off the top of my old heater with the new rinnai unit. You said that would burn the unit out in a year and it’s not covered under it’s warranty. So is this company worth dumping?
Matthew Ong call me at +19042385349 and I will go over it with you.
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.
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
I have a question if you can answer, i will have a 250 Gallon propane tank, and a Rinnai V65EP tankless Heater, that will be running just the Shower and The Kitchen/Bathroom sink, 3 people living in the house -- how long might that tank of Propane last?
Let me take this as far as I can and the Rinnai V65EP estimate could be useful for you. I can tell you how many gallons of water the Rinnai can heat based on it's 100% duty cycle run time. If you use it for say 2 hours per day total, your run time would be 2/24 or 1/12 or 8% of 100% run time until propane tank is dry.
Propane: 91,502 BTU per Gallon. x 250 gal, (assume 100% fill while 85% is more realistic). Rinnai V65EP spec: 150,000 BTU (Maximum) or 1 gallon propane is consumed every 37 minutes. Lets convert to hourly propane burn rate. 1.7 gallons propane consumed per hour of operation at MAXIMUM heating rate. So a 250 gal tank of propane will power this Rinnai continuously for 152 hours or 6 days and 8 hours. Factor in the claimed energy efficiency of 80% later. The Rinnai V65EP produces 6.5GPM of hot water or 390 gal hot water per hour. Measure your hot water consumption against this 390 gallons per hour times 6 days 8 hours to see where you stand. If you use a total of one hour of hot water per day, multiply 6 days, 8 hours times 24 and get 152 days from one 250 gallon propane tank. If you use two hours of continuous hot water, halve that to 76 days or more than two months. YMMV
@@dsweedler thanks so much for the reply -- the salesman told me it should get an average of 1 year on that 250 gal tank filled at 85 percent... i may rethink getting one on the info you told me -- Thanks so much for the reply.
@@kkandrettiTwo small things that could tend to make the run time closer to one year rather than my estimate of 152 days. The first is a biggie. If your hot water consumption is less than the rated 6.5gpm when you demand hot water, the estimate should be adjusted to the longer propane tank refill as the water heater is not consuming it's rated 150KBTU propane consumption. If you are typically using 50% of rated capacity when in use (3.25 GPM), then double propane tank refill time (and halve your propane cost per year!). I am not familiar with external propane tank installs but I don't believe they include a flow meter totalizer like standard metered natural gas installs to measure propane consumption. If yours does, then measure your current weekly propane consumption to get an idea of your needs. In general tankless on demand is much more energy efficient than any tanked water heater and the most modern Rinnai units are super efficient compared to older tank designs due to modern high efficiency heat exchangers.
The second is an error in my first paragraph. It is off bigly as I typed a percent or division rather the correct multiplication. So it is 12 times the one hour rated consumption for daily rate and not the 8% at a two hour demand usage per day.
@@dsweedler Thanks - takes note of what your said. :) Keep up the Good Work.
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 ??
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
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.
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?

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!
Having a problem with exhaust freezing over causing a code 10 on a rinnai rl94 unit.I live in Northern sask.where currently temp is > - 30.any recommendations to solve this problem
Unfortunately no you need to just check the vent often sorry
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.
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
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.
Appreciate all your Renaii videos. Do you have a video that explains a simple way to clean out any obstructions (wasp nests, dryer vent stuff, etc) that may be blocking either the exhaust or air intake on a vertical non-condensing vent pipe. The vent pipe goes directly up from the unit in the garage, through the attic, and terminates above the roof. Have read somewhere where people have used a leaf blower to blow air from the vent opening in the unit up and out. But will that clear out any debris in both the intake and exhaust parts on the non-condensing vent pipe?
unfortunately you have to remove the vent to clean it out. Mike
@@ThatTanklessGuy Thanks for the quick response. I think I’ll need to hire someone - don’t want to go on the roof and not sure how to take apart and reinstall the vent through the attic. By the way, your video on fan cleaning was excellent. After getting code 10s took out the fan and there was a lot of debris including two wasps, several moths and other stuff. Cleaned it all out, replaced the fan and the heater is working fine now. Finally, last time I flushed out the heater, I messed up the plastic water filter inlet cover (using pliers). Saw your video with the removal tool and ordered it ( came with two filter/cap assemblies). Made taking the filter cap off a very easy task! Thanks for your help!
Wait, what? Why would you need to prime a drain bottle? Is there a pump built-in?
Can I vent a Rinnai heater and Rinnai boiler and use the same venting exhaust ..I have a exhaust and fresh air going up?
david brinkman no you can not I would put two separate vents out the building 14” or better apart
Swim should use 3” schd 40 pvc only? Or can Swim use 2”?
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.
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?
How far away does the vent have to be away from windows and doors?
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?
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!
How would you adapt from the condensate trap to your cpvc? Fernco?
The bottom of Rinnai’s trap will fit into a 3/4” CPVC coupling. You don’t have to glue it just strap it to the wall very good and run the pipe to some type of drain.
Mike
Does the vent tube have to be 1 inch away from combustibles just like b vent?
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
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.
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!
I currently have a Rinnai that is malfunctioning. Getting a "10 code" on the control box. I've checked everything and it is all clean. The vent pipes are old and the gaskets are dry rotted. Could that cause the "10 code"?
cwestallen yes that could be the problem. But it also could me the heat exchanger is clogged
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.
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 ??
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.
Can I put inside my chimney concentric liner ?
Yes as long as it totally concentric venting and use a vertical termination. Seal the top and bottom and your good to go.
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?
I get a foghorn sound with my unit after running fine for about 2 years. I've flushed with vinegar a couple times, but it didn't help. Noise seems to come after the unit runs whether someone had just used water or not. I experimented by turning my recirculating pump on the lowest setting, and the sound became rarer. I have it back turned to high and now my hot water turns cold periodically. Super annoying. Even saw an error code 10 pop up. I've taken the fan out and exhaust. Everything is clean. Any thoughts on this?
what is the model number, gas type and about how old is it. Mike
@@ThatTanklessGuy Hey - Sorry - didn't get an alert on your response, but I posted and upvoted another video. I just came across your video and saw my post and your reply.... It's an RUC80. I replaced the burner unit myself (thanks to your video) and realized that the issue was dust build-up in the ceramic screen above the burner. I had same issue pop-up about a year later and paid $1000 to a plumber to disassemble and clean and reroute the intake to what they said was the correct way. I am now getting that sound again. I hate this unit for not having an easily removable and cleanable filter.
Oh, and the age of the unit at the initial foghorn was barely a year and a half. The age now is about 5 years.
so for the rl94 I cannot use pvc?
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.
What would you recommend for the smaller camp sized ones for venting through a diy outhouse wall
I would go with the concentric if it’s a non condensing unit like a V5.3
@@ThatTanklessGuy plz show me
