The smoke smell issue -I had it- IS RESOLVED %100! Call BK or PM BKVP. A new big fat gasket is the fix. The installation MUST be accomplished as per given instructions. Not hard to do, though. My Ashford 30.1 is perfectly smoke-tight. The gasket installation is not in the usual manner as the larger gasket diameter has to be accommodated by special means.
Satisfaction guaranteed.

All this time, everyone says, firebox is under a negative pressure. Can’t be the gasket since any leak would suck air in! Great news that a fix/cause was determined.
