FWIW I wanted to post this for some reference on this stove.
I loaded er up with small split black locust on a good bed of coals and things got a little bit too hot before I could ease it back down. Shut the Primary off and the secondaries kept raging and climbing. I took the ash pan out and was able to locate the secondary air intake. It's all the way to the back above the OAK and its about a 1/4" x 2 1/4" rectangle opening behind the primary. Stuffed it with foil until things got controllable again.
