I'm reading my manual and I see that they do not list any specific desired temperatures for the break-in fires for a Hearthstone Tribute. It says the first fire should get the stove warm to the touch...but not too hot. I have a stove top thermometer. Should I concern myself with an actual temperature reading? Or should I just get the stove warm on the first run, and then progressively warmer w/ each additional fire allowing the stove to cool completely between fires? Do they forgo giving a desired burn temp. because of the variables in the heat absorption of the individual cuts of stone? I'm asking because a friend who just did this with a new stove(iron) had specific temperature guidelines to follow with the break-in fires for her stove listed in her manual. I appreciate your input!
