i loaded my stove (napoleon 1400) up tonight north south with alot of wood on a nice bed of coals. then i damped it down once it got going alittle no its still damped all the way and the fires roaring. the stove top temp went to 750 so i wanted to check the temp uper right corner and the temp there is 500. manual says best is between 500-600 do not exceed 700. do you thingk im overfiring what should i do? i heard stoves with ash pans let some air in that effects the damper. what do you guys thingk could there be something wrong with the stove? how do i stop a run away fire?
