Hey, I had this stove installed for last winter and had the same problem. When the temps get down to -10 or more it doesn't seem to matter how careful I am I can't control the fire. Maybe the thermometer is broken. Here is a video of the stove an hour after a cold start. I closed the damper all the way after about 5 minutes with six splits in it. I have a 35' chimney. Nothing is glowing. I don't know if this is normal or not: Any help would be appreciated.
