It think you're stove will be ok at that temp. It happens every year a couple times to someone on the forum, believe it.
I was "freshening" up the fire in my cook stove one time and I didn't even have the ash door open, just had the slide wide open and the stove in direct draft (not circling the oven) and like William I smelled that hot metal smell, ran in the kitchen and the two burner plates and the piece that holds them on top of the firebox was just starting to get that dull pink they start at. I threw the oven switch, closed the MPD a bit and let her come down. When I used my infrared thermo on it I got the h signal which means it was hotter than the scale reads (950 degrees)
It was just a hair over though cause if I moved the lazer a bit I got the 900+ reading. As soon as it dropped down a little I tossed a couple scoops of fresh anthracite on top and it and that cooled it back to a reasonable level where I could set the controls normally.
Good old cast iron didn't really bother it a bit on the old gal but it was enough to scare me into a timer too.
