Hi, new to this forum. I recently purchased a United States stove company "king" pellet stove from tractor supply 5502m. The pellet stove is working awesome and I love it, but my glass gets dirty fairly quickly.. Within 5 hours for sure. Is this normal? Also I notice a lot of pellets the blow out of the pot glowing. I've only ran it in auto. The inducer is a newer model I guess.. It ramps out and down instead of staying on continuously. It's functioning and heating great, but just bugs me the door gets dirty so quick. I'm burning pro pellets best ones in michigan.
