Good install or not?

[Tom Yeager]

Single wall H2O Heater vent connector. Does NOT pass through the real wall, but does pass through a single sheet of dry wall ("A" side in picture) beside the real wall ("B".) Obviously NOT 6 inches of clearance. The wood stud is protected by a piece of dry wall (arrows.) Adequate heat shield? Combustible? ( this makes it fun: http://www.rumford.com/drywall.html ) Good or bad install? Tell me what you think, because I can't find the answer!

It's snowing in Denver...

I would write it up as a lack of clearance to combustible material.

[Wayne B. Wilson]

To close , refer it to a qualified contractor.

[Jeffrey R. Pope]

It's wrong, and needs to be corrected.

In these situations, I usually suggest replacement with a B-vent as a simple and reasonable solution.

[Matthew M. Berman]

What Jeff says B vent only requires 1 inch clearance to combustables

[Tom Yeager]

That's what i thought, just seeing if anyone would support my client's theory that drywall is not combustible and is acting as an adequate heat shield over the wood. I know, I know, never let a client talk you out of what you know is wrong! But he king of had me going... Thanks ya'll!!!!

Yup, no reason for sgl wall to pass through a wall...
