Hi to all! Newbie here and my head is spinning with pipe choices to connect my wood burning stove! The facts: Pot belly wood burner (designed for 6" with an oval exit) I'm going up appr. 32", make a 90* and then out through a combustible wall (standard frame construction) Another 90* outside and then up 7 feet with chimney pipe to clear the 1 story roof line. My head is spinning with single wall, double wall, triple wall, the oval stove exit, the damper, the barometric damper, the thimble...i can't mix brands.....help! Here's what I think I know: Black stove pipe for interior Silver chimney pipe for exterior I need a damper I might need a barometric damper The thimble is what the pipe passes through to leave the house I need a single wall to bend/flex into the oval shape of the stove exit but i want to use double wall for better clearance to walls and ceiling. Cement the pipe joints? Pipes are VERY EXPENSIVE! It looks like the pipes will cost as much or more than the stove. Soooo...any help designing what i need would be greatly appreciated.
