I’ve got a new 590 that won’t heat up and it seems like the auger is over loading the fire box. I’ve talked to CS twice but didn’t get anyone who seemed to understand the problem or a solution. I’ve adjusted the delivery rate, manually lit the pellets and cleaned the fire box several times. Every time I start the fire the box (manually or auto) it eventually overloads and spills out pellets while only smoking. I don’t remember the brand but the pellets were a “premium, all natural” pellet from Lowe’s. Anyone had this issue, too? Any ideas other than changing out pellets?
