First I'll say that I have absolutely no prior experience with any type of wood burning or pellet burning appliances - so thank you for keeping a resource like this message board available for people like me! This season I acquired a new to me pellet stove. It's a 1991 Lopi Heritage Bay (Pioneer Bay) Insert. It had been sitting unused in a friends basement for a few years and had some surface rust so before I installed it I did a bit of work to it - all new paint (twice), all new gasketing. Seeing how it seemed pretty straight forward, I did the install myself - running a 4" stainless chimney liner up my existing chimney making sure to use excessive amounts of silicone and the high temp aluminum tape at the tee connections. No smells of a leak and no readings on the CO meter that I placed on the mantel next to the stove. The question I have though is what exactly is the ash output supposed to look like. It seems to me like I'm getting an excessive amount of ash from the pellets. I've tried multiple different brands from lowes, home depot, and tractor supply. I know they're probably not the most premium pellets but they're affordable. I've recently been purchasing stove chow - they seem to give the best heat output and lowest (by comparison) ash. The ash that I'm getting is pretty dark and very fluffy. I've tried adjusting the the damper and the flame itself will adjust but it doesn't seem to affect the ash output in the least. Is there anything I should be looking for or is that just the nature of the stove? BTW - I do a thorough cleaning of the stove about one a week but have to empty the ash box about every 3 bags of pellets because it's close to overflowing into the burn pot. after one bag the ash box is about 1/3 full of this fluffy ash. The flash from the camera made it appear much lighter than it really is.
