Purchased a house that appears to have an old Buck Stove 28000 but there are a few things that make me think it's not a Buck. It has no damper control but a welded piece that simulates the damper handle. It has a 6" round flue outlet thst is connected to a 6" flue liner all the way up with a chimney cap. It is installed correctly. No fan visible. Anyone have a clue as to who makes this. There has been a little hasp added that seems to tighten up the doorl seal at the bottom. Wouldnt be needed if the seals were replaced. (Will do this).
