On my F2400, I have to get it pretty warm to get secondaries going (Load N-S, bringing the stove up to at least 600 before I start closing down on the air. Usually peaks out at 700-750). After about an hour, get it closed down to 1/8 open and I'll have coals to re-light the next morning after about 9-10 hours. One other thing I've noticed with turning it down.... if I closed the air too quickly (say from 3/4 to 1/2) and it kills the flames, I can open it up all the way to get the flames roaring again, then close it down from full to 1/2 and it'll sometimes kick start the secondaries.
Where do you have your thermometer?
