    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!!!!!

    Exactly! Such a deal I have for you....such a deal......get 'em while they are hot, since I'm either selling the company or putting it up on the shelf soon!

    I have to admit they look very nice and are perfect for the solution! I spent a chunk on the stove, I am kinda leaning towards a minimal cost fix. I was thinking of something like buying an 8" pipe to drop over the 6" - then filling the void between the two with something with a high R value for the 1" space - then adding an 8" cap???

    My flu is 32ft high - SS lined 6" pipe inside clay 9x12 - external masonary. Wonder what the worse case temps are up there???

    Sounds like you want a length of 6" class A factory chimney with a rain cap ? It would most likely have to be stayed because of the height and not so secure structural connection.
