The problem Im running into is when I fully loas the stove for an overnight burn. Everythings going fine, good secondaries, and I shut the air all the way off. The fire continues to burn like the gates of hell have been thrown open. Stovetop temp easily hit 800*, much hotter than Id like. Even shutting down the air completly won't bring it back under control. I know that there's no way to comletly shut all the air off, but it should be choked enough to maintain some control. Is this a problem with the air lever not functioning properly, or being damaged? These very hot fires make me a bit nervous. Any suggestions?
