I have a 40 year old Vermont Casting Resolute stove before catalytic-Stove has worked flawlessly for 40 years - Now I open the bypass damper for about 15 minutes when starting the stove then shut it down after to hold heat - the stove vents up the chimney fine with the bypass damper open but when I go to close the bypass damper it vents smoke out the doors - Any solutions ? I just swept the chimney and cleaned the inside of the stove-Could it have something to do with the damper in the upper back part of the stove ? Is there a space or holes in that damper to let smoke thru when the damper is closed and could they be clogged ? thanx
