Amazing how 2 diffrent owners can go from a creosote plant smoke dragon stove . To a clean burning almost zilch creosote with diffrent chimney . And aparently dryer wood? My grandfather owned this 80's built stove before me and i rember growing up the pouring smoke from his masonry chimney . The leakage and stinch of creosote how that thing never turned into a volcano up the stack i'll never know. Only time i get noticable smoke from chimney is when the thermo controled draft door shuts . And yet that not like i rember seeing years ago from the same stove. Now when i fuel it on coal well yeah then she smokes LOL
