Ya that manual doesn't cover proper cleaning for some reason.. I have this stove, she's a work horse but a bit loud in the shop even, I can't see how it would scorch the pellets in the auger as its very far away in comparison to most stoves as long as the lid is closed and the combination motor is spinning, the Combi motor runs both intake and exhaust fans on one shaft. I modified the air intake behind the RH door and separated it so it only draws outside air(it passively sucks inside and outside air, there is a kit you can buy, I just cut up some sheet metal instead and fit it), I also modified the draft dial on the lower RHside so it would practically close as I run it on idle often and there is a ton of draft from this stove, you might wanna have this dial half-wide open for lighting.
*The manual does't show you how to clean it properly, you need to pull the 3 panels and upper shield, and stick a coat hanger through the top left corner and blindly scrape away and through the bottom left corner leading to the Combi motor exhaust side and vacuum using small hoses, you need to remove the access panel to the combi motor exhaust side and brush the fins and housing and vacuum it out, you'll need a new square gasket. The stove is the same as a Drolet ECO-55 and made buy SBI, all the parts are available from SBI Quebec and they will send you the proper cleaning instructions if you call them, but I will attach them here to save you some time.
