hi everyone. this is my first winter heating primarily with wood and just am trying to get the hang of it. so once i get my fire going, what is the best position for my flue blocker? ive been keeping it about 3/4 closed and it seems to be the hottest. is it best to keep the door open a crack? my stove has a tiny little air vent, but it seems like it doesnt allow enough air in. ive been trying to get it so i can hear a woosh of air going through the coals. am i on the right track or is my method stupid?
