Hey i have a quick question i converted an old insert to free standing put a 8" pipe up 3ft. to a 90 degree then 3ft. to the wall where it goes to double wall pipe. out to another 90 then up 25+ ft. All pipe was new and I have been operating this stove for 2 months i overheated my pipe after the first 90 degree once and it was my fault i opened the air to and made a blast furnace so I disasembled the pipe cleaned out the residue and reassembled, 2 weeks being later, now being more careful now we were running it more choked down I am getting a black resine leaking out the pipe even along the long seams running the lenght of the pipe. I tried a control burn in the pipe to clear out the resine but it just flames up and the pipe by the wall runs 600 +degress (red hot) then starts smoking off the paint and resine, basically scaring the hell out of the wife, my question is how do i reduce the fast buildup of creosote in the pipes it seems way to fast to start iternal fires in the pipe. or could it be the 8" pipe instead of a 6" just not sure? Thanks sme
