I just purchased and installed a Quad 7100 in Montana for my (under construction) new house. I have stick framed the chase on the inside of my house (3 sides of the chase are inside the house, 1 side along an insulated and sheetrocked exterior wall). My question... should I insulate the remaining 3 interior chase walls? Will the chase be a major source of heat loss (or cold air radiating) in my house while I'm not burning? The total length of chimney is 34 ft., straight shot, 27 ft. of which is in a vaulted ceiling. Does the remaining 7 ft. above the roof need to be insulated as well, or is it to short to make a difference. Thanks for your time!
