Bending/warped air tubes

First question is, how red does the insert get when this happens?

That insert is beat up. Like others have said, here’s what needs to happen next.

1. Get the insert inspected by a pro, as well as the chimney
2a. If the insert is damaged, will need to be replaced
2b. If the insert isn’t damaged, order new tubes

No matter what, get in the habit of setting a timer on a phone so you don’t forget about it.

Done right you won’t need to be cleaning it out like that. Get seasoned wood. Black on the glass indicates wet wood.

The tubes do kind of support the baffle above but they’re connected to an air supply. Under normal operation and even just slightly over firing the unit, they can turn red but not sag at all.

It would be great info for everyone if a pro could tell us what they are looking for when they inspect a stove that's been overfired, do they have the knowledge to identify problems in the field, and what are they looking for to identify a ruined stove. PROS, please share your expertise

No pro here, but I'd look for broken welds at all seams with a flashlight. In order to do this effectively, the insert has to be pulled. For most folks thats definitely a pro job.

Also, if the tubes were that hot, the chimney liner was glowing also, and sounds like for extended periods of time. That would need to be closely inspected for damage. I'd take a close look at the socket seam, and appliance connector where the liner attaches.

Sure I'm missing something.

It is nothing special and we do it for every stove we work on. You just go over it looking for damage of any kind.
