I have a Breckwell P22 that isn't working well. I am burning Lignetics Premium Quality pellets. I don't know if they are to large for the auger to put out but on heat level 3 at 15 second intervals it drops 1-8 pellets. Most of the time it's 1-3. My house is 1100 square feet and it is only reaching 64 degrees. A little chili. Is there different size pelletts i can try? Also I purchased a thermostat and can't seem to get that to work either. I also have cleaned the stove top to bottom. Thanks in advance for the help. Happy Holidays everyone
