Forgive me for asking, I'm sure this is a dumb question but I have to ask.....I'm installing 6" stove pipe for my wood furnace. I got a 6" piece of double walled stove pipe/damper and I'm trying to figure out how smoke doesn't leak out the sides of it once it's installed. Whats to keep the smoke from coming out of the two holes they drill to install the damper in the pipe? Am I supposed to seal these up somehow?
