I have a Breckwell Big E pellet stove .It has a high BTU rating of 55000 Batu's .My question is what are the BTU ratings for the five thermostat settings?I ran mine on manual #3 and got my first floor 650 sqft up to 80 degrees in 20 degree weather. This was way way to hot for me and I put the stove back on high /low .I have 5 settings on this stove.
