Hi, I just had a Country Winslow insert installed (2nd one). The first one I had when I went to light it blew the glass out all over my room. Apparently the damper was closed from the factory. So they bring second one out..now I am having problems with it running and then shutting down after about 10 hours. It is not out of pellets. Called dealer they said to adjust the damper. The damper does not make a difference at all. The flame burns very low almost going out. Also it is burning the pellets and spitting them out before they totally burn creating a large amount of ash. According to the manual you only have to empty the draft drawer every 50 bags. I am burning cubex pellets and have an AOK installed. I am going to call Monday just hoping someone could give me some insight. Thanks, Shyann
