All things being equal...................tell us about the "rogue load" that goes crazy/uncontrollable. I had one yesterday with the same white oak that I've been burning for the past month. I loaded the "little big stove" up on a regular bed of coals with 4 medium white oak splits, closed the door, and went to the laundry room to transfer a load from the washer to the dryer..............total time: less than 3 minutes. Get back to the stove room, and the stove is going "nuclear" with flames looking through the glass.................... although the stove top thermometers are only registering 450-500*F...................but my flue thermometer is running almost 1400*F!!!! Slam shut the air control and turn on the stove fan to cool thing down. Stove top maintained its temperature.................but the flue took a while to come back down. Wood seemed the same as most other loads................it just "TOOK OFF" for no apparent reason. And before y'all axe; I can verify the time away because I know the "commercial" time on the program I was watching at the time and I got back long before they were done!! What say y'all?
The only time I have gotten any "rogue" (if you will) burns is when the wind kicks up and the draft is affected. The draft control on the IS if pretty tight, other than windy times its well managed.
To me that's not really a rogue load since it came right back under control once you shut the air down. I consider it rogue when the air is shut down and the stove is still running away. When the temps are low outside a stove will draft like crazy in a short period of time. In fact with my stove when the temps are low outside I don't even open the air all the way up on a reload.
Agree with others heavy wind and cold air. Mine sounded like a train the other night. No my chimney wasn't on fire.
