I have been having problems with PE Summit insert putting out heat. I use oak that is 1.5 to 2 years old from my property. The wood lights easily, but lots smoke rolls out into room until the flue heats up enough to draft even with the window open. The problem is that I have a hard time getting the insert up to temperature. I can get it to 550 to 600 F, but it takes a long time and most of the wood is burned up by that time, and if I turn the air down, to soon, the temperature never gets above 400 F. Also, if I shutdown the air all the way when I reach 500 F, the temperature drops. I have been having this problem for almost 1 year.
I have an external chimney with terra cotta tiles and a flex SS liner to the top. The chimney is 2 feet above my roof peak. I installed a 24 gauge block-off plate with ceramic fiber insulation above it. The SS liner is not insulated. I have a corner fireplace with a long off-set, and the guys who installed it had an extremely difficult time getting the liner down the chimney. After I had problems with temperatures, the place where I purchased the insert said I could never get an insulated liner down the chimney with the long off-set. I have attached a crude drawing of my chimney setup. So is my problem the result of the uninsulated liner or the off-set? I thought about insulating with Thermix, but I'm not sure if that's a good idea in case the liner ever needs to be removed.
