I’m on day three of using our new IS stove and am looking for some assurance that I’m not doing it wrong. On almost every load of wood I’ve burned so far the fire gets to a point where the cat probe goes up to 1400+ or even 1500 degrees even though the air control is all the way closed. On one fire this happened when the air control had been closed for well over an hour. STT is in the 350-400 range measured to the left of the flue collar. The manual states the cat is best run between 500-1400 which is the reason for my concern. Is there a max temperature limit for the cat probe? If necessary, is there anyway to bring the cat temp down besides having the air all the way closed?
