learnin to burn said:You got it, The coil is calibrated to the TStat so as the coil cools down the air opens to allow the stove to get back to it's set temp. Once there is no fuel left and the coals aren't producing enough heat to keep the coil hot the air will shut down unless the TStat is set to at least 3.
Before I hooked up my stove I played with the TStat and could hear the opening and closing of the air damper. From the 1 to 2.75 there was nothing and at 3 the damper would open. Lowering the Tstat from 3.5 I could hear it closing again as it passed 3.
Gotcha, thanks. Must be the temp of the firebox, not the cat? When I turn the fans on, the cat seems to cool down but I don't see any compensation in the firebox.
