Is the side of your stove the combustion chamber or blower shroud/heat exchanger? Harmon is certainly a heavier gauge than the posters stove (at least the ones prior to the "take over"), 600 is generally the max point of recommendation on a combustion chamber top (its very hard to get those temps on any secondary layer of the stove and if you did... something is warping someplace i assure you!)... the combustion chamber would need to be at 800 to enable a blower shroud to reach 600.
On the posters stove those side panels are HUGE fields of flat steel sheets!
gauge wont save those from distortion after 600 degrees unless they built in a gusset system or supporting stiffeners of some kind.
