Gas Hot Water Heaters need to be vented. The common method is using B Vent venting material. In this video we are going to go over proper installation and code requirements on B Vent water heater installation.
Thank you. That was excellent. A good overview of the correct way to vent an appliance. And lots of reasons & explanations why it has to be this way and not that way etc. Very good
Excellent tutorial ! Thank you 🙏🏼. Going to be moving my water heater to a outside metal enclosure(Currently in my kitchen ) . Going to run my B vent through the edge of the eve . I do plan on using all the materials you mentioned in this video .
Awesome video man, some one just took out my electric water heater n installed a natural gas 40 gallon tank, i was concerned about the venting, I'm in a trailer home going out side wall, I'm happy with the height but not the venting pipe, I'll go get b pipe n do it myself, the hard part was done, ☮️from🇨🇦
In this video, Plumbing Solutions provides an amazing explanation on venting a water heater. It leaves no room for error. -- JodyTucker | Jan. 28, 2022
I am replacing my water heater which has existing B vent. I want to buy a new water heater that is 2 inches taller - is it possible to modify current B vent or do I have to reinstall entire thing ? Thanks!
Roofers are not allowed to replace flue caps in Colorado. I thought the double wall was mainly for condensation. The single wall pipe would condensate moisture on cool down
damn good video! very informative, no bs. Super helpful with answering my question... can b vent be run from a basement, out the side wall rather than through the existing chimney flue (vertical termination)
What could you speculate if after a new home build, ticking noises come from the hot water heater vent which runs close to rooms as it goes up through the 2nd story subfloor to the roof? And what could be done about it?
Hello there! Is there such things as a 'low-height draft hood'? I'd like to increase the pitch of my 3" vent as much as possible. I cannot lower the water-heater or raise the other end of the vertical vent where it enters (or connects) to the vertical section of the vent. Currently, the pitch is quite alright but I just like to increase it. Thank you for your great videos. 👍.
Sorry, new to this thing. The code says the b vent should not exceed 45° (and one 60° is allowed). I am confused. Can I make a 90° angle just like you did in the attic? Thanks
I have a traditional water heater vented through my roof Is it possible to change the direction horizontally to go out the side wall with this water heater?
Yes but you can not terminate horizontally . You still have to go vertical above the roof line. You could get a direct vent heater they terminate horizontally and draw their air from out side. but they cost more.
Question: How do you air seal the B vent (Obviously that doesn't happen I don't see anyone doing it) Like HVAC ducts you can snap them together and then you need to tape and mastic them to keep the air in (even the factory joints). Why and how do you not do this with B vent carrying a more important gas? is it the capillary/ vacuum that keeps it from leaking?
Was hoping to see something on oval b vent. Manufactuer says 4 and 5 inch can go in a 2x4 wall but the numbers don't add up. The 5 inch b vent is 2 7/8 outside thickness so to maintain a 1 inch clearance one would need a 4 7/8 stud. ? Edit: I reread the instructions for hart cooley and it says a 1 inch clearance is required for draft hooded appliances except except when the b vent is used in the stud space. Now, I'm really confused 🙂
@@PlumbingSolutionsLLC all the major manufacturers say you can as long as you use their firestops which center the oval b vent in the 14.5 inch stud space at top and bottom. I don't understand why the oval b vent needs less clearance but the instructions seem quite clear that thats the case. Check out Selkirk's oval b vent instructions.
? I got a bradford White venting into an old asbestus vertical but condensation is dripping at the ceiling do i change to b vent. Will that get the moisture out?
I looked at my water heater installation directions. It says you need a minimum12" vertical section before any bends to insure proper drafting. Any comments?
@@dsbakp That is not a requirement it is only a recommendation! I started with a 45° on top of my draft hood to a 24” straight and my inspector passed me in New Jersey!
Is it expected and acceptable for small amounts of water drips to follow the B vent pipe down from the roof during very heavy rain? Mine does this, even with a termination vent cap inplace.
well, it shouldn't. The air moving through it should be hot enough to cook off any condensate especially in the summertime. You could be missing the end cap.
I couldn’t locate this pipe in attic, will this be connected to fireplace in some cases? There is no pipe at all in the attic, water is leaking to my basement where this vent goes into the ceiling of my basement, so I need to identify the source.
Manufacturers stamp on their b vent that it must be 1 inch from combustible material. Unfaced fiberglass and rockwool are considered non combustibles so why what code prevents their use in contact with b vent?
It's code 502.7 in the international fuel gas code book . but the code book also says follow Manufacturers guidelines.. so it what ever the Inspector thinks.. lol
Great video, but what does 'go back ten feet' in the attic mean?. Ten feet from what? Back from what? Toward what? I understood how you don’t want it terminating too close to the peak or the eaves, but that 'back ten feet' has me stumped.
