Hello, getting a liner and insert installed soon. The installer measured the flue tiles to be 9x13, outside dimension. When asking about insulating the steel liner, he said 90% the time he does not do it. He usually insulates the top only. He said he would put insulation on the bottom if I wanted. Back to the liner, There is not enough room for an insulated wrapped liner, and he has never used vermiculite or blown in insulation. Can I use a smaller diameter liner to connect to the 6" stove? It is a 27' chimney, on outside wall of house.
Thanks.
Thanks.
