New here, lots of good info found so far. I have a plate steel insert that was never used and taken out of my inlaws house. Would like to set this up in my shop, don't have to worry about combustibles or fumes, cinderblock building, stove has a 3 and 1/2 inch X 14 inch rectangular opening for smoke on top. Is there an adapter for going from this to 6 or 8 inch pipe? Thanks, Jim. edit: Found another thread on this, stove in that one is a silent flame, mine looks identical. found a stack for it at hearthstove.net. Welcome other suggestions/sources though.
