I recently bought a very nice blaze king ktj-302. I have some questions about it. Im unsure of how to correctly use the thermostat. There are times where i have a great bed of red hot coals and reload the stove, wait for a active fire before sealing the door and it may be a great burn (600 to 700 degrees via pipe probe). Other times i can have a great bed of red hot coals, wait for an active fire and seal the door. My probe quickly tells me im burning way too hot (1100+ degrees) and other times i may burn to cold (less than 300 degrees). So how can i have a great burn for a load of wood with the thermostat set directly between low and high, reload, wait for active fire and not get back into the same temp range? Sometimes i get lucky but most times i have to fidget with the thermostat to tune it in. And im talking a few degrees one way or another could be the differences between burning to cold or burning the house down. Thoughts?
