Loving my Osburn 2400 insert. It took me a while to get used to an EPA stove, having burned the last 30 years in an older Jotul cat stove. The thing I find trying to burn down coals is I have to pull the coals forward, crack the door a bit, and pull the air out half way. It will maintain temp for the hour I do this and it really burns down the coals. The question I have is the air control. If I open it all the way, will the stove allow all the heat to go up the chimney? I have tried to just rake the coals forward, door closed, and open the air all the way, but it does not really burn them down as well! Suggestions?
