ABSTRACT:
Apparatus and a method for assuring safe retrofit installation of a flue damper in a hot air furnace. The flue damper is electrically connected to the original furnace control circuit by engaging a flue damper connector with a portion of a printed circuit board containing part of the furnace control circuit. The physical configuration of the adapter and the printed circuit board require removal of a jumper conductor within the printed circuit board prior to connection of the adapter thereby assuring that the flue damper is correctly installed so that it will be in the open position before the furnace may be ignited.
