Ok Jotul Oslo/500 (or any owners)... this morning...started to turn my air control down to 1/2 at stove top temp of 350. Temp kept creeping up. Got to 400 and turned the air inlet down to 1/4th. Temp crept to 500. Turned air inlet control all the way down. Temp crept to 570 and settled. This was all in the matter of 30 minutes before the temp settled and sat there at that 570 for 30 minutes before it started coming down to 560 and continue down. The flame was going pretty good with secondaries putting on quite a show which usually starts at about 350. Did not use my flue damper but was ready too as thought it was going to continue to rise. Don't mind saying...my heart was pounding. Got the fan out of the attic and started running it...and was just about ready to use the flue damper (would it have done any good). The splits were of good size and had about 3 of them in there. I know some of you probably will get a good laugh as I am now... but thought I was going to have to open the front load door as some has suggested here. The flue temp never got above 550. It makes me nervous to stuff this thing as once it's going...I'm going to try and get some chimfex today haha. What did I do wrong or is there something I could or should do different as I would like to stuff this stove for the long overnight burn? Jeff
