I got an craft wood stove from my cousin and I've had it for about a month. I am BURNING through would like no other. If I put 4/5 pieces of split wood 4in thick, Itll burn through it in about an hour. Should this be happening? I am closing the bottom dampers about 90-95% of the way and closing the top damper( the rod that pulls out and controls the vent to the flue to the point where its almost closed as well. What am I doing wrong? I'm not sure of the model, the chimney exhaust exits the stove through a triangle duct like the one pictured below. Can anyone give me insight on these?
