Hi all:
I've tried to find my answer through general searches, so forgive me if these are easy questions and I just couldn't answer them to my satisfaction.
I have a new green mountain 60 installed in my newly built home - just installed by the selling company, a reputable spot in southeastern PA. The stove pipe exiting the top of the stove is a double wall type to enable us to get as close to the wall as possible but otherwise is standard black stove pipe entering into a ceiling box where it becomes class a double walled chimney.
My questions are on the stove pipe install. Specifically (see pics)
The stove pipe shows 4 seams between the stove and the ceiling (~6' above the stove). The seams are as follows from the stove to the ceiling:
- At the stove flange where the pipe slips over the stove exhaust (makes sense to me)
- ~8" above the flange there's another seam - maybe where a connecting piece ends? I'm ok with this I think though I don't know why it needs to exist.
- ~30" above THAT there's a seam as if one piece of black stove pipe is being inserted into another. This is what I don't understand. Further, at this seam there's a gap as if the stove pipe metal is very thin and flexible and it's not seated between the top and bottom pieces perfectly flush.
- Last seam is where it hits the ceiling.
To me, this doesn't seem right. It's a 6' section. To me an ideal install would be a single piece of black double with a seam connection at the stove and the next at the ceiling. The stove has a standard 6" outlet, so i'm unsure why a flange is needed between the stove exit and the exhaust - but I'm not an expert. The seam in the middle of the pipe with a gap in it doesn't look right at all.
Checking with the forum - does this look correct or incorrect? On a side note, during the pre-install measurements we agreed to route the outside air intake down through the floor and out through the band board and we were discussing a plain black steel hearth pad or stone/tile underneath. We went with the plain steel pad supplied by the same company and now they are unsure about drilling through it. Lol.
