My DuraPlus double wall stovepipe length from flue exit to chimney support box is 6' 2". I've got it all screwed down. 3 Screws secured at the flue. 3 Screws secured in the middle. 3 Screws secured at the support box. The pipe is perfectly vertically level.
I know there's some differing opinions on whether to leave the middle screws in or not to allow for thermal expansion. With a ~6' stovepipe should I leave the middle screws in or take them out so the pipe can telescope in and out as the metal heats and cools?
