Please show me where you buy them, nothing but junk out here.

Most are now like this one

But you can pick up an older version like a Griswold on eBay.

What was your stovetop temp when you noticed it glowing? I have a Lopi Republic and the manual says to measure the stovetop temp centered above the door. I know when that area gets around 650 or so the exact center of the stove under the convection deck is always a bit hotter and I wonder it it glows a bit right around the flue there. I have also noticed that with good dry wood my stovetop will get very hot without the flue being dangerous - around 650-700 on a probe.

Thermometer was pegged. I'm guessing over 1000 degrees. I found the hottest spot is centered on the lower step of the stove. If I move the thermometer a couple inches either way there would be a big difference in temperatures. Like you I find the stove can get very hot and flue temps be well within a safe range
