I started a fire this evening with a good bed of coals with 3 pieces of wood loaded n/s and 2 loaded e/w on top of that. Let the fire get hot and started shutting down the air in stage as I always do. Watched the fire for an hour or so and the temperature was holding at 625 with the air control just slightly open so I decided to go up stairs and get on hearth.com. I was searching the pages and I thought it seems to be getting hot up here pretty fast so I went down stairs to check the fire and when I turn the corner I found the stove have one he** of a secondary burn going on with a stove top temperature of 900 degrees maybe hotter and stove pipe temperature of 500 degrees. I shut the air ALL the way down and turn the blower on high until the temperature came down to 550. This stove like to run hot, and a stove top temperature of 700 to 750 is not uncommon, but when it gets to 750 I turn on the blower. This is the first time it has ever been above 750 but I think I caught it in time so I don't think it did any damage to the stove. Just one more runaway stove.
