Hi, I have a Sweet Home stove, model Apline Fir that needs some damper work. To me it looks like the current damper doesn’t open far enough, but I’m new to wood stoves. Is the damper in the stove ok, or should I replace it? The damper is housed inside the top of the firebox and is operated by a handle in the flue collar. Replacement will require some cutting I think, because the current damper won’t lift out of the flue collar.
