Ok guys - need thoughts. Maybe an easy one. I am hoping to get my new stove soon. I was informed that my single wall SS liner should be trimmed lower where it sticks out of my clay liner. Right now it sticks up 2 feet above the clay liner. Reasoning is it is a cold spot and will build up creosote quickly - it does exactly that - bad. BUT I have it 2 feet higher because my chimney has 2 side by side flues. One for the lower level where the stove is, and one for the upper level where my open fireplace is. Before I installed my original stove and liner, I had issues with smoke coming down lower level chimney while burning the open fireplace on the upper level. The 2 foot height elevation difference when I installed the liner seemed to fix the problem. My question: Instead of trimming down, what can I "wrap" the single wall pipe with to insulate the exposed 2 feet so that wont look like crap. Something like a foil or bubble foil insulation that will wrap the pipe and keep the last 2 feet warm, but still look ok as it is exposed. Thoughts??? Thanks in advance!!
