I believe that running the fan affects burn time and I see it affect the thermostat but I don’t understand how, being that the fan seems to be outside the firebox. I tam a week into a princess and the stove has exceeded my expectations. I am burning well seasoned dough fir and maple. I have had my heat pump turned to fan and it’s heating my 2500 sq ft rambler. There is an air intake above the stove, which helps. I am getting 15 plus hour burn times. These are amazing stoves.
 
The fan cools down the stove, so thermostat opens up more to keep the same temperature hence lower burn times (but more BTU per hour into your home) with the fan on.

If it's not needed for a higher btu rate (because very cold weather) or a better moving of the heat farther into the room, I suggest to leave the fan off. If you can heat sufficient without the fan, why not.
 
Stoveliker is 100% correct. It has been discussed many many times on here and I see it first hand.

I got A thermosat for my blower outlet. So I don't have to let the fan run all the time and waste wood. 20$ or so on Amazon. Best 20$ you will ever spend . Trust me. Ok now it's 25$ I guess.

The faster I have my fan speed on my insert, the faster the STT cools over the course of the burn.

Well, measuring stove top temperature on a BK is pretty silly anyway since there is a 1500 degree catalyst right underneath but also, the fan blows air onto the surface thermometer and artificially cools the bimettalic coil which shows a false low temperature.

I missed that this was in the blaze king sub forum. I was just speaking generally about non cat inserts
