Hello! I have had my Regency GF55 Pellet Stove a few days more than a month. Earlier today, while cleaning the soot off the stove's glass, I discovered a crack in the front pane of the fire chamber's glass. I realize the fire chamber is supposed to be air-tight. I do have a CO sensor in the house, and it still shows "0" for CO ppm. I have two questions: 1) Until the cracked glass is replaced, is it still safe to use the pellet stove? [Keeping in mind, I do have a CO sensor that indicates 0ppm of CO.] 2) Could the cracked glass be contributing to the high burn level of pellets? [To date, my stove has consumed approximately 42 forty pound bags of pellets in about 33 or 34 days.] Thank you for your advice!
