I'm building my (single story) house in S.W. Missouri and have a gently used, but older Jotul Castine F400. It's the one with the double front door. I'll also have a propane furnace, but hope to cut the propane bill a lot with the wood stove. I won't have the house finished this year, but I need to know how do I penetrate the wall for the stovepipe. I built the ext. walls with 2X6 studs. There will be an exterior chimney (also not built yet). I'm assuming there is some sort of special type of pipe for this--but what's it called? I'll be installing this myself and have done a lot of building over the years, so what's the absolute BEST, SAFEST way to penetrate the wall with the stovepipe?
