I have been thinking of putting in a woodstove and have a question about the chimney set-up. We are thinking about putting in a free standing woodstove on a bare interior wall. We have cathedral ceilings and my wife does not want to see 13' of interior stove pipe. My question: Can you box in that double walled stove pipe, say 2' from the stove top all the way to the top of the ceiling? I see that ICC Excel states that the double wall requires 6" to combustibles. If I were to frame, then use Durarock or similar, would that 6" still be required? I am trying to think of some way to box in the pipe without it looking too silly. I am concerned that if I box it in that the minimum requiremant to combustibles for the stove pipe would require a large box jetting out too deep into my living room. Please give me some advice. Thanks!
