I'm renovating a 1975 vintage house and have a 30' vertical flue from
a gas fireplace that I need to deal with. The flue is ~16" in outside
diameter and ~6" interior (double walled) and apparently the space
between the inner and outer walls is filled with tightly packed
fiberglass. There is a nearly illegible label that says in part "...
123 starter section".
Can anyone tell me the name of this type of flue so I can figure out
how much it weighs, how the sections are joined, etc? I'm removing the
gas fireplace and want to decomission the flue as easily as possible,
but it is resting on top of the stove insert with no other visible
means of support. It was lifted into place with a crane as one piece
into a woodframed chase on the side of the house. I want to frame in
some sort of permanent support and cut the bottom section out, then
seal the flue. I don't want to mess with the roof cap or anything
else, if possible.
Any info or ideas would be appreciated.
