We are pellet stove newbies....we have suffered a flood in our area which took out our boiler and fuel tank in September and have received a Whitfield Avantage I. We are having a problem with the pellets getting stuck in the tube that the pellets come out of after about 35 min of burning this happens even if the heat output is on 3,2 or 1. I have been searching forums for two days and all I can seem to find is problems with the pellets not coming out. If anyone has any ideas it would be so appreciated. Going to get cold here in upstate NY real soon and we wont be able to leave the stove on when we go to work with this problem.
