“ I also have the M55 Cast. Love this thing! A little noisy. I have it set on #3 and I burn about 2 bags a day. My house is 4k sqf but I have shut most of it off since the kids are gone. Heats the hous nicley. I have had no issues at all. I clean it out about every 2 days. Very easy.
I have been using O'Malley and TSC Brand pellets and both are so so. Wish I could find better grade pellets. I also heard on here somewhere that by putting the setting on "Muliti Fuels" the stove will burn more efficient. Any ideas? ”
