I doubt it. How are you starting the fire? I like using a top-down fire, criss-crossed kindling on top of the splits or wood briquettes. Heats up the flue super fast.Just a quick question. I have the wood stove in my garage. The garage is not finished, just shelled in. (No siding, insulation on walls and the attic is left open, not closed in.) Could this be a cause of my draft problems?
