I think I have to much draft on my stove. I know when its cold outside you get a stronger draft. Last year I was getting a lot of smoke when I opened the door on my stove so I added one foot of chimney and replace all the black stove pipe with double wall. Now its seems that the smoke and heat are sucked right out the top. I run the stove from 500 to 675. the chimney has a probe thermometers that's is hotter then the stove sometimes or run almost the same temps until I shut down the air suppy. I want to know what everyone thinks if i add a inline pipe damper to slow the draft on real strong draft days . I would only use the damper on times when I was home and in front of the fire so I could watch whats was going on. I burn 100% 2 year old oak Any Ideas what would help would be great Thanks Frank
