    Default Direct vent flue location

    What do you make of a direct vent PVC flue routed out the side of the home, but located inside of the cold air return? I wrote it up for several reasons, but mainly as a safety hazard. If that PVC joint hidden inside the cold air ever gets compromised, the carbon monoxide and other hot gases go right back into the system for re-distribution throughout the home.

    No authority in this area, but I think you did well by your client. The possibility of CO leakage is worthy of advisement, regardless of the codes and the mere presence of PVC inside breathable air chambers is another concern. If it's not a code violation, it should be.
