Stove getting too HOT

[BurningBrutus]

I have a PE super insert, i loaded it up tonight at 11pm got it going for about 20 min stepping it down until i closed there air all the way down at about 400F. For the next 40 min the temp slowly rises until it reaches to 750 and the metal in the upper right that also holds the firebrick in turns red! I have a very good draft as always and i seem like i can never turn my air down enough. I attached a pic at 12 midnight of it shut all the way down. It seems to be way to much flame. What do you guys think i should do?

Is there a different chimney cap i can put on that will slow down the draft?

From the pictures, it looks to me like the splits are too small and/or not packed tight enough- too much air space. Nice flame action though.

Bigger splits, for sure. Turn the air down sooner. I generally have it shut down quicker than that on a cold start. I don't go by temps as much as the way the fire looks.

Have you checked the door gasket? How tall is the chimney?

My temps peak in the 700 rang and then settle in the 600-650. With an 8 to 9 hour or so burn time. That is to say untill with coals racked forward again and temps at 250 for reload. Whats your burn time?

This. Once these stoves really get going it's hard to slow them down (AKA going nuclear). If I let mine get too established before turning it down it's a battle to get it to stay below 750.

And it appears that you may have load just a few smaller splits on a large coal bed. That is a recipe for big fire.

The Chimney is about 23 ft, but we got a wicked breeze back here and sometimes consistent good gust. I did the dollar bill test and towards the door latch and middle its not coming out unless you rip it, at the hinge side its pullable, but snug. Mind you this is a brand new unit. I did a full load, and yes i admit it might have not been the tightest packing job. I will try again this morning with a better stack and turn it all the way down sooner and see what happens.

Keep a good eye on it today, we're predicted to have pretty high winds at some point. I know ours gets harder to rein in when the winds are higher. Last night we had some good gusts and each time I could see the fire pick up, even with the air shut all the way down it got a good flame.
