Hello
Well, I have read that 4" venting is recommended in long runs and installations way above sea level for better drafting.
The Avalon Astoria has a 4" stove pipe which needs 4" venting even though it is not much different than other stoves. I also have 3" venting for testing other pellet stoves. Now I have had more leakage problems with the 3" venting than the 4" venting. It seems that like a car muffler, there is more back pressure in the 3" venting and that requires much more sealing!
I have seen regular pellet stove installs with either 4" or 3" venting. The 4" installs have a 3" to 4" adapter coming out of the back of the 3" stove's exhaust pipe.
So even though it is more expensive for the 4" venting, it just seems better and not many leakage problems?
Does anyone else have any experience and comments on this?
