My Clydesdale likes to get hot. This morning I was burning some of my so-so seasoned oak. When it goes into secondary mode I have the thing shut totally down but the fire continues to grow and the heat continues to rise. Stove top always likes 600-700 in this part of the cycle. Sometimes hitting 800+. This morning ... same thing. I tried the open door method. It cooled about 30 degrees and then started going back up again with a loud roar. So when she hit about 680 stove top I shoved in a nice ugly freshly split piece of cold green oak. Fire tamed. She started dropping and in about ten minutes was down to 600 and slowly falling. Looks like I'm going to be keeping some fresh split green wood on hand and also I'll be using one small one in the startup load to help control the overnight so I don't have to worry. Looks like a great way to use uglies too.
