Its gotten down to 34 degrees here in pa and i have had a few nights of experimenting with the p61a and i have learned what everything does and a few ways to increase effeciency with it. The only thing i cant figure out if how do you guys run it low on nights in the 30s and 40s? My 1800 sf home was 79 degrees upstairs with the stove set on auto/stove temp blower 75%/ feed adjust 3.5/ 2 on the temp dial. I dont see any smoke at running it this low and im not loosing the fire. Is it ok to turn even lower? I thought i read on here that anything under 2 is not recommended. My current assumption is that this p61 at full bore could heat the entire county.
