Since I'm completely redoing everything on and around my hearth, I want to replace all my pipe with new double wall stuff (probably going with Selkirk DSP). Since I have only been burning the King in the garage with a relatively short flue (it's 6" also), I'm wondering how my 35+' x 6" flue will draft in the house with this stove using the double wall. I'm going to be ordering parts soon, and it's easy to install the damper now. I was wondering what the BK folks thought about using a damper with these stoves. I normally wouldn't consider it, but with my soon to be better insulated long flue, I'm a little concerned about over drafting, even though it's a cat stove. Thoughts?
