This is my first post on here but I have been reading this board for a while and I love it. I have ta U.S Stove 6041tp that I am using as primary heat. during the day we leave it on a lower heat setting and at night we turn it up a bit. the problem I am having is that for the past week it has been overflowing with pellets sometime during the night and last night we woke up to a house full of smoke. Any ideas why this is happening. My daily settings are heat range-3 room fan-5 draft fan-3 and auxillary-3. At night I increase all of these setting by 1 or 2. I would really appreciate any input. Thank you.
