I just bought an englander evolution pellet stove to heat my basement. I live in a raised ranch with 10 inch uninsulated block walls in the basement and looking to heat about 1300 sq feet area. I installed the stove with about 5 feet vertical vent inside and horizontal through wall. I have ran the stove for about 12 hour stints and the basement temperature only moves about 2 degrees. It has been cold with temps in single digits but basement stays between 54-57. I cleaned the baffles of the stove and heat is coming from the blower and ran the diagnostics and all checks out. I just burned New England pellets and now I have an overflowing burn pot. I have tried running the stove at all levels. The bottom 3 buttons are at factory settings. This is my first pellet stove. Any suggestions would be greatly appreciated as I am about ready to sell it. The stove is rated up to 2000sq feet
