Gas Water Heater Vent Piping

[@80ajflores]

Thanks dude. I managed to replace mine with no problems thanks to your videos. Make more.

[@omargutierrez8840]

alex flores nice! saw this video and my mom needs hers replaced

[@lewiscruz3818]

Thank you so much for this video Claude. I hope you are getting some donations/tips or monetary compensation for sharing your know-how. Folks - this gentleman does not have to post any of this. And he has to work in cramped, hot, uncomfortable confined spaces to do this kind of work, so keep this in mind when you attempt to do this yourself or when you hire someone else to do any work up in your attic. Sometimes we forget or are fast to dismiss the rates people charge to do work for us, but forget to consider that they are doing the uncomfortable or dirty work or tasks we ourselves might not want to do or just do not know to do properly. If this helped anyone to save some money and time, be sure to throw him a few dollars he saved you from paying a professional plumber's hourly rate.

[@theartofplumbing]

Wow. I appreciate your kind comment and concern for monetary compensation. I am humbled. All the things you mention. Right on the mark I'm trying to give people an option. I'm a consumer too. I know what it's like when money is short and time is available. Let me give you a chance. Watch the video and you will know the extent of your own abilities. 😉

[@Milosz_Ostrow]

Good video. I'm having my house re-roofed now. I will instruct the roofer to install new flashing to accommodate a 3-inch double-wall vent pipe as shown in this video and abandon the 50-plus year old oval asbestos-cement vent that was built into the garage wall. We don't have hurricanes or tornadoes where I live, and I've only had the pilot blow out once in 25 years, but I think the new Amerivent and Duravent caps are much more wind resistant than the stuff from my father's day and if they're installed "in the clear" in a garage space, they're much easier to inspect and maintain. 🙂

[@theartofplumbing]

Nice great timing. I appreciate your comment.

[@Mgoods57]

I wanted to comment that I am having to do this now. I purchased a new model Whirlpool efficiency heater. The safety valve switch broke because my flue pipe was like this and had to have the 4 month old heater part replaced. I am in the process of installing this exact pipe/process today/tomorrow. I can tell you with 100% accuracy that this needs to be done if you purchase a new water heater. I am glad to have found this tutorial/information video. Thanks again!

[@theartofplumbing]

Thank you for Your imput. Yes it is very important and safe=. Again thank you.

[@ikennaq2]

Thanks. This is the one of the best water heater venting videos I have seen on KZbin. Well explained process of venting gas water heater.

Nwannaa Umuigbo Thank you.

[@BrandonRBatman]

Atmos just tagged and shut my heater off for this very problem and my plumber is in Alabama this week. By this video, I think I can do the old pipe myself. Thanks!

[@drex22]

Very helpful for my DIY hot water heater install. Thanks for posting!

[@wintermachine]

On my Ameri-Vent 4" The instructions say to line up the 2 seams for disassembly. When assembling it the instructions say to turn it to line up the seam with the X. then look at each tang to insure it is pressed into each square part. The triangle tang must be manually pressed into the long square part to LOCK the pipe. I used 1 older Ameri-Vent 12" pipe with the new Ameri-Vent B-Vent stuff, The older pipe didn't have an X on it but was the same in all other aspects.

[@torotheplumber3788]

This was a very good video super detailed thank you !

[@theartofplumbing]

I really appreciate your kind comments and support. 🙏

[@chelsey6893]

Thanks for showing this. Replacing our unsafe vent was easier because of this video. Thanks!

[@metusbatmanv1438]

Exactly what I needed, but I wish you showed how you made the connection to the top of the water heater. Do you screw in the duct hood connector to the connection sitting over the flue on the water heater? Also what do you do when you are screwing together the pieces of flue but the self-tapping screws are piercing the outside, but just bend the softer inside metal?

[@DanielGarcia-mf5nz]

Best Video I have seen. Thanks.

[@theartofplumbing]

I appreciate you, and I am humbled

[@shaffer4220]

Excellent video. One question, can’t you cut/shorten the vent pipe sticking outside the roof? I suppose it cannot be done due to the snap end? In other words, no way to adjust the length?

[@theartofplumbing]

Yes you can adjust vent pipe, but your right not by cutting the. You can buy them in different leagth 1' 2' 3' 4' 5' 6' 8' and 10' 👍 great question

[@KingNidus]

dO YOU HAVE TO ADD SHEET METAL SCREWS, at the base where the flue pipe meets the vent hood on the water heater?

[@theartofplumbing]

No you don't, but if this was single wall duck work yes.

[@KingNidus]

​@@theartofplumbing Thanks, I have a 12 inch b vent above my water heater in the attic but it doesnt protrude out the roof EXACTLY like your video with the same flashing and vent top. Im in houston also. This will help me alot

[@theartofplumbing]

Nice

[@ahjuns]

Do you need to use b vent for the entire run or just where it passes through the ceiling? Single wall is much cheaper and easier to work with. Thanks!

[@theartofplumbing]

Yes, you do. Most definitely no single wall should not be used with a B vent. Yes, the single wall may be easier, but B vents are made for going thru the roof and ceiling. The single vent can only be used going to a chimney with a vent liner.

[@sandyc1100]

you dont show /say if the vent cap goes inside the double wall pipe or on the outside?????

[@theartofplumbing]

Sorry, but yes it goes on the inside of vent. 👍

[@DanielLynds]

Good video. Needed this. Thanks!

[@theartofplumbing]

Glade I could help :-)

[@carlitovonflux3934]

Great information! Made me realize that my flu pipe is not up to spec.

[@theartofplumbing]

Thank you. Glad I could help

[@Billybobranders]

Maybe someone mentioned this already. 100% silicone is not paintable. There are other products that have good adhesive qualities that can be painted in case you want to paint the flashing.

[@theartofplumbing]

Good to know, thank you. I appreciate your input

[@Nutintoitbut2doit]

We see a lot of those, handyman special. Good video

[@jamesgreenblat3561]

My GF became a sheet metal products manufacturer in 1912. My father told my GF he wanted to go out to the field and created Able Furnace Sheet Metal & Chimney Company. He serviced the community for 56 years until cancer took him. I myself followed in their footsteps. I did everything from heating and Ventilating to roof repairs, gutter and downspouts, made to order roof outlets, downspouts, chimney decks (22ga.) and chimney sweeping (1st to charge by the hour). we reside in a HOA development, and I inspected the termination venting system for the waterheater & central heating. Much to my dismay I found that the roof flashing and termination cap is a .025 combo roofflashing and termination. thus, as you are well aware of the dura-vent is about 4 inches below the cone, and I can easily put my hand between the MB and the flashing cone. Thus, CO is entering into the attic and also in the master bathroom and hall bathrooms ceiling fans. Also, we're getting back draft from very high winds and I do believe this in all causes the heat exchangers of both appliances to burn more rapidly, and also causes heat loss because of the rapid exhausting (because the proper type-B termination cap somewhat reduces the rapid gases exhausting) and thus provides a more efficient heat exchange! I commend you for providing such a comprehensive and easy to understand for the layperson! I would like to send you a video of our situation, and I also have a few photos as well. Sincerely, James Greenblat

[@jen123317]

How much does replacing this vent cost? In Texas?

[@theartofplumbing]

Any where from around $6 hundred up to $2 thousand or more. This is one of those jobs a plumber would have to see. Is this a 1'2'or three story, does the roof have a sharp pitch not very safe for anyone to work off , some time it calls for a roofer to make adjustments then that's a added cost. Houston, TX area.

[@michellehood3345]

So the silicone caulk is used as a glue to adhere the plate to the drywall...will that heat up and fall off?

[@theartofplumbing]

No it's good.

[@drdoomecj]

There is red heat rated silicon as well

[@theartofplumbing]

Yes it work good. 100% silicone

[@donklaing]

Is there a protrusion height the vent must have above the roof?

[@theartofplumbing]

Yes 18" 👍

[@donklaing]

kzbin.info/www/bejne/Y6nGqpKJg7WlbNE this and other code requirements I'm seeing. 18" is all?

[@donklaing]

So your saying it should be 18" above the crown of the roof?

[@kmodbox3779]

Hi Claude. Thanks for the great video. I'm in Houston and wonder, why is it wrong to use the flexible pipe prior to wall penetration? Is this code? Thank in advance!

[@keninatlanta8452]

Thanks Claude, I appreciate you work.

[@wildamerican2771]

My pilot light keeps going out. I have a horizontal direct vent with a thick stainless steel pipe in the center, surrounded by a second pipe that seems like one of these tubes. The center pipe is not even connected to the center pipe going outside. I’m trying to find a horizontal kit that will fit for my unit. What do you recommend?

[@sipanon9711]

Wild American Just had same issue. Replaced the water heater to find out they come with a mesh “skirt” that goes around the bottom to keep dust/lint out of what I call an intake pipe that pulls air thru, up & out the flue. Mine was totally blocked with dust due to it being beside the dryer & back door. It was 11 years old, have never seen any mesh on a water heater but seems to make sense & no problem lighting the pilot now. I’m sure u’ve fixed it by now but just letting u know to keep the bottom clean & clear of dust, pet hair etc & attach the mesh to keep the pilot going. (My install guy apparently didn’t caulk something & it’s now leaking from the ceiling to the floor 🤦🏼‍♀️).

[@theartofplumbing]

I would call the manufacturer of the water heater. There going to ask for your model no, and serial no. Hope this helps.

Can you use tankless gas water heater vents on a 40 gal tank..are they interchangeable or should you use a different kind?

[@theartofplumbing]

90% of them you can't, but I believe the Brand water heater Navien water heaters makes one that will.

[@michellehood3345]

will the venting come inside the new water heater packaging...or will I jave to purchase it separately...im sorry for all the questions...I'm trying to educate myself before the professional comes into my home

[@theartofplumbing]

@@michellehood3345 No problem, but no it will not come with flue pipe, and you may need an electrician to install a plug outlet for it.

[@floydstearns9745]

Hi Claude...A very instructive video!! I'm in process of replacing the old water heater in my garage, which vents straight up thru the ceiling, then about another 5' thru a crawl space, and out thru the roof...about 10' total. I'll be replacing it with new B-vent pipe. My question: does the draft hood on the heater support the full weigh of the pipe in a case like this or do I have to add some type of clamp above the garage ceiling to handle it?

[@JDoe-hb7pc]

Someone terminated my old furnace but made it 6 inches. The buyers home inspector said it needed to be 12 inches. Do I really need to go into the attic to shove a new long 12 inch b-vent? Is there no other way than the attic spider route? I'm a woman. Is there no external jimmy rig thing to make it longer from the outside? Thanks!

[@theartofplumbing]

Sorry you or someone may have to get into attic. 😔

[@JDoe-hb7pc]

@@theartofplumbing Thank you so much for replying! The attic makes me cringe. By any chance do you think the inspector made a mistake? The furnace was like 80 years old and removed. It's not in use or ever will be. All equipment has been removed and thrown away. The floor was even sealed.

[@theartofplumbing]

Yes and no. In his mind, you may put the heater back in, but if you remove the vent from the roof and seal it off he may pass you. 😉Not unless he's an inspector with a God complex 🙄

[@JDoe-hb7pc]

[@dougharlow6037]

what's the proper length of the vent tube on the roof, to get a good updraft?

[@theartofplumbing]

No less then 18" from roof to flue pipe outlet.

[@theartofplumbing]

If there is a window or door with in 4' on same level. extend flue pipe 2' above window or door.

[@dougharlow6037]

@@theartofplumbing Thank you very much. Great video

[@CASANOVAPRO1985]

Good job, I’m running a job in Rockport Texas and was having a few words with the plumber about which one was the correct way. He said the first one was ok and it would pass inspection . But some of the others on the property are the way you did it sticking up about 2’ from the roof . What’s the code say ? And will inspector pass either one,? Do you have the code number ? Thanks for your video

[@theartofplumbing]

Abel Casanova 18" minimum from roof

[@burbs9607]

I have to replace and reroute my vent pipes. right now it comes up about 4 feet, 90 degree bend that turns into 4 more feet through an interior wall, then another 90 degree bend (exposed in the laundry room) and extends about 2 feet till it goes through the roof. this originally went through a drop ceiling then the roof but I have the room gutted. I have a small tight area but I will make the vent pipe come through the wall a little higher so it's not exposed and in the ceiling. also on the roof this pipe extends about 4 feet. is that necessary to be that long outside? it's a colonial but the laundry room is its own room off the back of the house. Another question is what type of plate (dont know the technical term) do I use on the inside of the roof where the hole is? I have a stud about 2 inches from the hole in the roof. And we use 3" pipe correct? These guys didn't use double wall either so I will be using double wall this time around and try using 45 degree bends rather than the 90.

[@sonicboomin]

I'm getting new water heater installed tomorrow. Apparently my 60 gallon was using the old vent pipe from older heater. Its 3 inch . What happens if he needs to install 4 inch vent ? Connection to chimney flute is 3inches.

[@theartofplumbing]

I would recommend you have your chimney checked for and clean fisrt. And yes if you go up in size you may need to make the opening at the chimney bigger. Again I would live that part up to a HVAC tech to check out. Good luck.

[@sonicboomin]

@@theartofplumbing thanks someone coming tomorrow to install new heater.

[@sonicboomin]

@@theartofplumbing is that something the tech installing heater should do? make opening bigger?

[@vacuumboy6.0]

I've got a what I think is a good question. I've currently got and electric water heater but we are going gas, what I'm asking is can I vent through a side wall? With it going up a quarter inch per foot?

[@eddiegenie]

You’re video was very helpful.I’m gonna change some faulty ventilation myself.But I heard that the flue pipe needs to extend out higher than the peak of the roof.Im guessing that’s optional though?

[@theartofplumbing]

eddiegenie Its possible its a code in your area. If you have a window are door close by. You want it to extend above that.

[@bigups8103]

Can u just replace the vent in basement only? Just found out it's been leaking. Scary!

[@theartofplumbing]

That is scare. If your gas water heater is in the basement, its most likely going strait to a chimney and its single wall flue pipe not the the flue pipe in this video, in that case you may need a liner installed in your chimney. I would recomend a heating and cooling tech have a look at it.

[@ririhope2672]

I've watched some of your video and have a question. A plumber recently unclogged a main drain outside of my home and broke the vent box to access it. Now my question is can I use a temporary fix to cover that drain until I can get the vent box fix. My concern is the cover for waste and I bought a new vent box but did not realize it was in cement..

Quick question for anyone knowledgeable ... I have a gas water heater in my garage an, it has the normal exhaust vent from the top to the roof ... But, I also have 2 huge vents ... one on top and on the bottom of my wall ... Both are leading outside causing freezing cold air to get into my garage ... I wanna close these vents but I am worried it might be bad ... Anyone with advice please help me out ... I am tired of having a freezing cold garage, what can I do?

National gas fuel code says 1 foot above the roof if it is at the peak, the way the vent was ok, it was probably grandfathered in, but changing the vent was probably for the best.

I can use silicone to do this on an furnace vent? It doesn't melt? Thanks so much for this video!!

I think you can find silicone sealant that is rated upwards of four or five hundred degrees.

The venting should also be strapped and secured properly..

[@Z-Ack]

Didnt think you had to use double walled for a wh vent pipe.. thought double was only required for a chimney pipe.. i know at least rigid metal pipe is but not double...

[@Z-Ack]

And i know about support requirements between the two with 3 sheet metal screws per connection along with a quarter inch rise per foot or whatever as well as downsizing being a no no but thought single was ok...
