I've been running this unit for a week(25 PUF). It seems to run good. I have it in my cellar, granite slabs and stone. The temp. can get to freezing on bitter cold days (like if it is 0 degrees F). I've insulated all cracks and have been able to keep the temp. @ 50F in the cellar. This keeps the floors warm, and that makes it easier to heat this house. The hopper holds 240lbs. I am looking for a balance and understanding of what to set the heat and the blower at. During the week I keep it at 7 heat and 7 blower. If I go away for the weekend I drop it to 3h 5b, just to be safe about ash build up. Any suggestions on a better balance. What do the settings actually do. The stove is new to me and this is my first post. If I seem a little windy forgive me. Thanks Dick
