A damper control device may include an appliance control programmed processor for controlling a gas burner, the appliance control programmed processor including a lockout register for storing electronic data information, and a damper control programmed processor for controlling a damper, the damper control programmed processor including a damper request register for storing electronic data information. The damper control programmed processor may be configured for selectively opening or closing the damper responsive to status of the damper request register and controlling status of the lockout register to indicate status of the damper, and the appliance control programmed processor may be configured for controlling status of the damper request register responsive to a call for operation of the gas burner and operating the gas burner only if the lockout register is in an unlock status.

Integrated damper control system

An integrated damper control system is used with a gas fired appliance including a gas burner, a flue and a damper for selectively opening the flue. The damper control system comprises an appliance control including a programmed processor for controlling the gas burner and a communication interface device. A damper control comprises a programmed processor for controlling the damper and a communication interface device for communication with the appliance control communication interface device. The damper control programmed processor is programmed to selectively open or close the damper responsive to status of a damper request register and to control status of a lockout register to indicate status of the damper. The appliance control programmed processor is programmed to control status of the damper request register responsive to a call for operation of the gas burner and to operate the gas burner only if the lockout register is set to unlock.

A system for operating a damper comprises a flue pipe assembly, and a damper movable between an open position and a closed position within the flue pipe assembly. At least one thermoelectric generator is coupled to a surface of the flue pipe assembly. Operation of the damper is achieved by the thermoelectric generator harvesting thermal energy from the flue pipe assembly and converting it into usable electrical energy for actuation of the damper.
