On 12/12/07 I had a Saranac Pellet insert installed and think I have a Problem. We are running the stove on setting #2 and find that after about 12 hours the Burn Pot gets plugged with ash that is not a powder. It is solid and has to be scrapped out. When this happens the Auger activates every 10 seconds. Could the Problem be the Pellets. We use the Barefoot Premium brand.
