Any comments about how I sealed my pipe? We had some smoke leakage out of the appliance adapter after initial install. We had a small bead of sealant so went back and loaded it up with more and that took care of it. While I was at it I sealed the gap between the outer wall and inner pipe that is down by the adapter. Someone made a comment that this needed to be open for air exchange but this pipe is not like the Selkirk where it is the fresh air space. I thought it was just double walled for cooling value. Only reason I put the sealant on was in case of internal joint leak. Figured it couldn't hurt.
