Is is absolutely necessary to insulate a stainless flue liner? I have seen some mention of it on here, but not much. I am refurbishing an old wood furnace to install in the basement of my house. The house has two clay lined flues side by side (from way back when of the coal furnace days) that run up the center of the house. I was thinking of purchasing a complete liner kit (from ebay). Do I really need the insulation?
