Need Advice: I want to temporarily install until I am satisfied that I like where stove is located before I make cuts and install correct. I want to remove window, frame in opening and use DuraVent thru-the wall kit with DoubleWall for now. This locates the stove close to where I plan to make final install thru ceiling if satisfied. What I want to know is if I can get by with not all insulated pipe on outside of house, as I need to make angle to avoid overhang at this point. It will look funny, but I want the trial, then if happy, I do full install. Stove is England NC 13, and will not be at high heat, we don't get that cold here. I will never push it at all. Also, how much flue length is necessary? This looks to be 6 feet insulated to get outside to verticle, then I can use another 3 feet insulated before it gets funny. Then there would be bends and singlewall... There would be plenty of clearance. I would appreciate any help.
