I dunno what you guys are doing, but there is no way the brick rails should be glowing. Ive had my Summit up to 800 degrees and no glowing.
First off, Check your doors with dollar bill. Secondly, do not confuse the s.s. heat shield over the ceramic blanket on top of the baffle as part of the baffle. It is only a heat shield clipped on over the blanket. Yes Mine bowed, I pulled it off and straightened. Didn't really need to, but had it out anyways.
As far as the baffle, yes it will bow slightly as you have a wide expansion of metal expanding and contracting as it is heated and cooled. Mine ever so slightly bows, but does not effect performance. As with any baffle, your going to have some expansion. Whether its a baffle plate setup., or tubes or ceramic. Some rot out, some get clogged, some bow, some break. Several of you admitted to over firing your stoves. Don't blame the baffle or manufacturer for damage caused by human error.
I am not trying to sound harsh, and hope you don't take it that way. But if your OL is overfiring the stove, tell her to stay the f away from it. Unless she wants to shell out the bucks for new parts or a new stove. Those photos show definite overfiring. Again, the plate on top over the blanket you see is not the baffle, it is a heat shield, and there is another on the inside of the stove top. Is that what the single pc of s.s. is laying in the picture? Take that off and see what the baffle itself looks like.. If its shot, get a welder to make you a new one. Cause if overfired, your stove warranty is spent anyways. And if you do, try having him make the baffle out of a lil thicker stainless and see how that works. I would have one made and have the fabricator add a couple long rails in the center of the baffle to help support that wide expansion of metal. Or let the OL pay for the new one and tell her each time she forgets to cut the air down to start saving for the next one.
You have to remember, although some of us are lucky enough to heat all or alot of our homes with these stoves, they are SPACE heaters, and not furnaces
