I have an Eleana Air Plus Pellet Stove that creates a lot of soot when burning. I've cleaned it, doesn't help. Tried pellets my sister burns in her stove which runs fine. No difference in mine. Auger runs every 3 to 4 seconds. Stove shuts down when ash pot becomes full of a hard tarry substance. I've been reading the forum here and it has good suggestions. I need some detailed instructions on how to adjust the auger speed and exhaust speed. Any information would be greatly appreciated as the company that sold it to me no longer sells this product and won't help me much at all.
