What type of vent is this?
What type of vent is this and is it acceptable for use on a propane water heater?
I see them used as laundry vents quite often which I write up but I haven't seen one before on a WH.

Re: What type of vent is this?
We don't really use propane around here (except the yuppies for grilling). I would think that hood would create too much flue resistance to work well. I don't see many of those but when I do it's usually with a power assisted unit.

No, that is not an acceptable cap for a gas vent. Nor is it an acceptable gas vent or gas vent flashing either. |

Re: What type of vent is this?
Rick,
Roof Jacks are used to receive and cover venting duct pipe from kitchen and bath fans, and for attic ventilation. The steel design provides maximum leak protection with a press-sealed built-in roof flashing. Vent caps provide protection from rain, snow, debris and may also be designed to resist vermin.
I don't believe that is classified or designed for flue gases
The one in the background is an attic turbine vent, whirlybird

Re: What type of vent is this?
Yeah, but what kind of vent is it? That is my main question.
Not approved for a dryer vent either I know.
Is it possibly for a sewer vent?

Re: What type of vent is this?
Rick, I feel a trick question coming up.
Like Jerry has said in the past, just because they sell it at Home Depot does not mean it is ok to use it.

Jim,
Not a trick question.
Just in a p1ssing match with a plumber who owns this home.
He of course is BSing my client to think this vent is acceptable for use on WH's and furnaces.

Rick
I see those on some older roof replacement and they have used them on water heaters. I have also seen them on what barry said.
I did inquire about them some time ago and they are not allowed on gas appliances

Re: What type of vent is this?
Here's the trick question?
Is leather cover plates UL approved for switches and receptacles?
We're not talking about a few covers, they were used completely through the home.
Made in China so says the sticker on the metal plate on the backside.

Useless.

Correct.

Nope.
Go back up to the top - "useless".
I can't think of anything these are allowed or approved for use with nowadays.
Not bath fans, the duct needs to be sealed to the inside, and there is no way to do that. Bath fan roof vents require screens (or dampers), and those typically have neither.
Not kitchen hoods, the duct needs to be sealed to the inside, and there is no way to do that. Those require dampers.
Not clothes dryers, for the same reasons the those above.
Not Type B gas vents, those require the vent to be connected and sealed to the Type B Vent Gas Cap, and those have no way to seal the Type B vent to the flashing and those are not Type B Vent Gas Caps.
Back to "useless". |

Yes, if UL listed and labeled.

Don't care where it is made, if not UL listed and labeled for that use, then the answer is 'No'.
A "Made in China' sticker does not cut it. |
