* }4 `7 M8 q: ]2 q* t) rIf close a lot of vents then the heat generating by the furnace can not completely bring out to the house from the heat exchange( the amount of the heat generate by the furnace is not changed), then the temperature of the furnace is going up slowly, eventually the high temperature cut-off sensor will work to stop the flame, the blower will keep running until the temperature come down. The furnace will run again automatically.
