This is in a garage closet with no visible combustion air return. And not 18 inches off floor.
Could it be a sealed combustion chamber and if so can you tell with out removing cover?

FNG so be nice.

No, this is not not a sealed combustion chamber.

Yes, this w/h must be 18" off the floor in any garage installation. It appears to be placed on a 3 1/2 inch platform, so 14 1/2 additional inches is needed.

Hi to all,


Chip, from what I can see from the pictures the installation would not meet current codes, both in terms of combustion air supply, and also as you state insufficient height above the garage floor.

Are you sure there was no other air supply inside the closet ?

regards

Gerry

It looks as though the closet/enclosure was added around the unit. Is it possible the unit was relocated to the garage from an interior portion of the main structure? In either case, simply removing the door will in most cases provide sufficient combustion air for residential water heaters of 75 gallon and smaller capacity located in a garage. I also agree, the unit is not properly elevated above the interior slab surfaces.icon_idea.gif

I see you edited it from “visible venting” to “visible combustion air”.



A louvered door will also work.

So does that mean this w/h needs to be raised and add a louvered door?

When was the home built? I too am in the Panhandle of Florida and I see water heaters in MOST garages and many if not most older ones do not have the WH built up off the floor to meet the 18 inches requirement because that was not a requirement at the time of construction. Typically we see all kinds of things that are either not “code compliant”, unsafe or poorly installed at the time of construction. Just from looking at this WH I know it is not a recently built home. Here is where you have to advice your customer in particular what is safe and what is unsafe while avoiding the dreaded “C” word (code). I personally often tell them that something that was allowed at the time of construction no longer is allowed by code. GFCI is a perfect example of a safety item that I routinely recommend upgrading to if not present or required at the time of construction.

Joe,


A simple recommendation will suffice. Observe and report. If they fail to take your advice, it's not your problem.

House was built in 87.


No visable air combustion venting.

I would recommend a louvered door, an increase in the platform and the installation of a CO detector in that room, to guard against any backdraft.
