    Question Water heater venting

    I came across this venting set-up for a hot water heater in the basement. House is 20 years old. I immediately remembered the vent at the wall of the basement and thought that this was not acceptable because this is not a high efficiency water heater and should be vented above the roof. I have never seen this type of metal vent(single wall?). I was told by the owner that his contractor from the build did this installation and said it was acceptable. Any help would be appreciated. Thanks in advance.

    The vent shouldn't be in contact with the insulation and the paper facing shouldn't be exposed.

    I have called out the insulation. Is a direct vent water heater that is not high efficiency allowed to vent at ground level? What about gases and exposure to people around them. This is directly under a deck.

    AO Smith allows it to be under deck a min of 12", and if under the deck is open on at least two sides.

    This should answer any questions you have. I ran into the same type and found the manual.
