Well, I just had to coment on this subject. Travelnutz pretty much nailed it. Heating systems for the most part are closed loop. If the abient air recirculating inside is so cold that it cools the firebox down, then the blower control will close down so that the burner can raise the firebox temp back up. When the firebox reaches a certain temp then the blower switch closes and the blower engages, as the abient temp increases so does the blower on time. When the set abient temp is reached then the burner will close and then the blower.
