We bought an Englander, model 25-PDVE/55-SHP22E Mfg date of 02/05, from a friend. This is our 2nd year burning this stove. This week it burned back the auger shaft and burnt the gasket between the auger and the auger bearing. I have a new gasket on the way. I have noticed that when burning the pellets are not burning completely and it piles up on the burn pot. I clean my stove every 2 to 3 days. I just did a deep clean. I clean out my exhaust pipe about once a month. I am not sure what settings I should have the heat range and blower speed at. Our home is about 2000 square feet. Can anyone help?
