Does anyone know what the flame of a Harman p68 should look like. My dad gave me the stove this year so im new to the whole thing. The flame seem s to be very "aggressive", almost torch like. I have a small house so i installed outside air. I opted to use 3" vent pipe which is larger than the 2 3/8 pipe that you can buy from harman. is the stove getting too much air?? if so i thought the damper was contolled by the circut boeard of the stove? maybe this is normal for this brand of stove? any input would be most heplful!
