We have been running our stove now for a bit and my wife and I really like it. Just last week we had the stove top temp on the burn indicator go to the limit which is over 850 deg. F before we caught it. According to the burn indicator anything over 550 deg F. is considered overfiring. The stove and pipe never got red and nothing seemed harmed by it. I was worried that it may have voided the warrenty if it truly was overfired. What is truly considered overfireing? Just last night the stove temp went up to 850 and it appeared for no reason. I had all 3 vents shut rite down but could not seem to bring the temp down. There was no wind, the stove has an outside air source. I took off the side panel tonight after it cooled to reveal the 3 drafts vents. The burn rate air controll and the start up air control seemed fine but the rear air channel vent pad had some glazed creosote on the inside screw head and the was a small chunk of creosote inside the channel itself and the pad was indented some with the shape of the vent hole. There was what appeared to be a slight, very slight separation between the pad and the stove, but the vent was working properly. I've also been smelling some smoke at night rite over the stove. The piping is installed properly and has been sealed also. I tightened up the door latch just a bit in case there was a leak at the door gasket. Any ideas? It is a good stove and we love the glass door. My dad and I cut some wood with his little saw mill on Sat. I'll send some pictures as soon as I reduce the size.
