Hi all! Very interesting group here! So I have a new cast iron M55 insert burning Vermont Soft Wood pellets...(moisture 4.8% and ash content of 0.27) I love using the Premium pellet setting because it is extra quiet. I have noticed that when I use the regular or multi setting the augur dumps pellets into the ash bin....not good! All the settings are on the default "3" setting and I don't see any real differance in the Auto/Hi/Lo/Manual setting. I get a huge flame, must bigger than I thought I would get and a lot bigger than most of the competitors stoves. My question is on my dirty glass which gets dirty after only an hour or two! I guess I got suckered into all this Air Wash stuff and you only have to clean your glass once a week. After one to two hours, 40-50% of my glass is very dark gray to black. You can still see the flame through this part...but after 3- 4 hours the flame's visability id greatly reduced. I get no clinkers, I do get a small pile of ash on each end of the liner in the burn pot but I guess this is normal. Because the ash bin is so shallow, I was concerned that I would have to empty every other day but the ash is so minimal that once a week will be the time to empty. When the stove was installed, no magnehelic quage was used and I do have a very tight house. The flame however is vigoruos, bright yellow/orange, no black tips. Shortly after startup, I have a good pile of pellets, they are burning but I also get a lot of smoke....so I am curious, maybe this is all normal. Thanks, Bill ****I am only on day 7 and I have already done a full vac/cleaning of the entire inside!
