Just got it installed yesterday. I am brand new to this. I have gotten some good info from the web, from my dealer and from my installer but I am still having trouble with a couple of things. First, I am smell smoke...not a lot and it's only near the stove. Second, my glass is getting filthy! I am using great American pellets. I have adjusted the air flow numerous times. Too much and the fire goes out. I was told too little, and the glass will get brown. I need help
