I recently installed a Century 2000sq.ft stove and have been running it with too short of a chimney due to ice on the roof keeping me from adding the last section, today I added the last section and started a fire with four 2to3 inch diameter logs and it is cooking me out I shut the air control down and closed the damper in the pipe and it still has a really good secondary burn going. I dont want to open it all the way up and get the pipe too hot or should I open it????
