I know it's been awhile since I have been on here eventhough I do read through on occasion...been a crazy year, but I am having issues with my serenity and right now am using kerosene heaters because there is no one in my area who will look at the pellet stove. I think it just needs a good cleaning but I am afraid to pull it off the stove pipe...it will light but the glass turns black within a minute or two and the stove shuts itself off with an ignition failure warning...but I am thinking that since it lights and the blower comes on it's just the stove not getting enough oxygen to make the fire hot enough
