Ok, I know I'm going to get asked where it's at in the house, how old is the house, how well is it insulated.... all the questions.. But, If you have the stove set on stove mode, won't it burn the same amount regardless of where the stove is placed? Doesn't it monitor exhaust temp and control the rate of burn that way? I have a P68 and i'm not even getting 24 hours out of a bag. I have the feed rate on 3.5, the stove mode is set at low and the temp/rate (cant think of the name of that dial.. the one on the bottom left) at 4. I have a magnetic wood stove thermometer attached to the side of the stove and it's around 400-425. What do ya think???
