Pictures of a novices Blaze King burn last night,I think it's okay.

Stove top is hotter than I get with my Chinook for sure. BKVP said the cats can handle 1600+ degrees, so no worries there. I'd say it's perfectly fine. I don't know what the king stove top usually gets up to though. BK recommends 13% moisture or less, but 16% is fine... In my area I can't even get my wood lower than 15-16%. where's your stove top thermo sitting? If it's sitting right above the cat it'll probably read high.

Personally, I don't monitor stove top temps...the only thermometer I have is the cat thermometer.

1500* cat temp is fairly common for me after a reload, and I'll notice the cat temp drop some...near the 1100* - 1200* for a little while...then I'll notice it climb back up to the 1500* range. It'll do this for a few hours sometimes before settling out around the 1000* - 1200* range for the rest of the burn. Although, this scenario varies based upon T'stat setting...outside temps...inside temps...etc.

Cleans the combustor
Mine gets up there often, I was running near that allot when it was -20°.
No temp scale on the one on my stove, inactive & active. Only have a at temp probe.
No worries, you're having a good burn, more smoke & wood gasses, hotter the cat, it's doing what it is supposed to do

No flame and that cat temp is a good burn but you should turn the fans up so more of the heat ends up in your house.
