as most of you know i have been having alot of issues with my stove and its settings.......as i have been told the bottom 3 buttons only apply when running on low 1&2...so last night at 10pm i filled the hopper and set the heat and blower on 4 because as i understand the stove controls itself higher then 2......well its 7:30 and the hopper is empty...thats 9.5 hrs on a bag....and still a pile of unburned fuel.
