Hi, I’m new to pellet stoves. I bought this used and saw it working perfectly before I bought it. We cleaned it and got the damper unstuck and now it’s been one thing after another. It is burning very hot with a very high flame even on lowest setting. We’ve tried adjusting the damper and feed rate and it helped for a short time today then the flames got crazy again. I will include a video of what it’s doing. Appreciate any help I can get!
