I turned the pellet stove off Wednesday morning and left to spend Thanksgiving with my in-laws. We got back Saturday night, and I figured that I'd be able to turn the pellet stove on and enjoy some heat. The stove was installed on the previous Saturday, so it hadn't even burned for a week yet. Well. I got a huge flame, tons of pellets in the burn pot, half burned pellets falling into the ash pan, and all the fire alarms in the house going off. My first thought was "I must have gotten a lemon." My second thought was "Those installers must have screwed up." Third thought, "Those guys on the forum say that 99% of all problems are caused by a dirty stove. I shut the stove down and turned on the electic heat for the night. This morning I went to Lowes and picked up a Shop Vac with a filter and some drywall bags. Upon arriving home, I pulled the stove apart and vacuumed all the crud out of it. I started up the stove, and its been running like a dream ever since. This forum is full of useful information, and I thank you for sharing it.
