Greetings everyone, new to the boards, and I have some questions/concerns...
I've got a late sixties Pine Barren Stove that's approximately 3'Lx2'Hx2'W with a 6" top mount flue. It was part of a forced air heating system (totally enclosed in galvanized sheet metal, squirrel cage fan, the works), and I tore it all apart because it was worn out and hadn't been used in decades. It's located in my basement and last year I piped it to the chimney with two 6" black elbows and a 4' section of black pipe. I had terrible back puffing and a poor burn efficiency so I made some changes. I moved it closer to the wall (and sheathed it with corrugated sheet metal) and lined the interior of my 9" square chimney with the left over 6" galvanized duct. Coming off the flue I've a clean out, a trimmed section of black pipe going through the wall, and a black elbow at the base of the chimney (al 6") before the 6" galvanized chimney liner ties into the elbow. Everything seems to be working fine, but I'm concerned about the longevity of the 6" galvanized duct I used to line my chimney. It's pretty thin stuff and I'm mainly concerned with it deteriorating and having to fish it all out of the chimney later on down the road.
I've attached a sketch to better explain...
