I clean my stove out every weekend. Which I did last week. After I cleaned the stove out. I cleaned out the chimney with the leaf blower. After I put it back together I fired up the stove. Shortly after the pellets started to light. I heard a very loud snap come from the stove. I did not notice anything till about an hour later. I saw that the stove had a lazy flame and the burn pot was full of smoldering embers. Which had me baffled due to the fact I'm burning pine pellets. I turned down the feed to the stove and it continued to burn like this all week. It still kept putting out ample amounts of heat. Today I shut the stove off for cleaning. I would have done it soon but I was busy trying to search for a reason plus work got in the way. After cleaning out the stove as usual and doing the leaf blower trick. I fired up the stove. Well after the stove started to light. I heard a loud snap come from the stove. Now the stove is burning nice and clean with an active flame. I don't know what the snap sound was.
