I just bought a used p61 Harman pellet stove that is manual light and does not have a temperature sensor so I was wondering do I use my stove on room temp or stove temp ? 2 what do I set the temp knob on ? 3 what do I set the pellet feed on to get the most efficient use of my stove, I used it a little bit the other night and in about 4 hrs it was about 80 in my house with it on stove temp. Lowest heat and lost feed will that feed more than a bag a day and then I was worried and turned to off position and it wouldn't go off even after a bit it keep feeding pellets so I had to unplug is that not good to do thanks so much for any help out there and God Bless !!
