Real quick question on 6" stove pipe damper.

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?

It can come out if draft is not sufficient. If you have good draft the smoke will be drawn straight up the chimney and not have to find other places to leak out. If your not using the damper and the holes are just open you can fill them in with furnace cement or you can put sheet metal screws in to plug up the holes.

But the double wall will retain heat to ensure proper and/or better chimney draft.

I would agree with that except in a situation where there is more than 8-10' of connector. I always have to clean those stoves 2 times per year where the double wall guys are 1 timers.

Shane, could you explain why 1 time for double, and what kind of stove/pipe again takes 2 ? Thanks.

Edit: I have double wall black from stove almost to wall, then double wall stainless out through wall and all the up the side of the house.

The ones I have to clean twice per year are the ones with large vaulted ceilings and 10+ feet of single wall (Not necesarily every one). The pipe loses alot of heat and does build up more when compared to other stoves in similar installations using double wall stove pipe. On older stoves where more of the heat is lost up the flue this is not as prevalent but with a 70+ efficient stove you can see huge difference.

Thanks, that helps a lot.

Ah, Ok. Thanks for the info. My main reason for double wall is my kids sometimes play in the basement and I thought the double wall pipe would reduce the chance of them getting burned if they touched the pipe.
