I've always tried to keep a close watch on my temperatures since I'm still learning my stove. The highest temp I've ever measured (above the doors with an IR thermo) is around 450. The night it got that high I was a nervous wreck. Today, I came home from lunch and arrived at the same time our nanny showed up from picking our girl up from school. I had given her some instructions on how I typically run the stove and all has been fine since. Well today as I got out of my truck at the house I could smell a metallic smell which is typical from running our stove. When I got inside it was pretty warm (with temps in the 30s) and I could tell the stove was pretty hot. I checked it with my IR and it was just under 500 and had probably been loaded an hour or so earlier. Needless to say I closed the air down all the way (which was probably 1/4 open at the time). Question- is it possible that any damage occurred from running this hot? I've been running the stove all day and things seem to be fine- just not sure exactly what/where to check. I've since given some more thorough instructions on how to load/run the stove to the nanny. By the way our unit is a Kozy Z42.
