A power generation system for use with a gas fired appliance including a main burner and a gas supply line includes a pilot burner assembly for igniting gas supplied to the main burner and a controller. The pilot burner assembly includes a thermo-electric device configured to convert thermal energy into electrical energy, and a pilot guard. The pilot guard has a first end defining a gas inlet and a second end defining a gas outlet. The controller is configured to receive a signal from the thermo-electric device, and control the supply of gas to the main burner based on the signal. The controller is powered by electrical energy generated by the thermo-electric device. The thermo-electric device has an internal resistance matched to a load resistance of the controller to facilitate maximum power transfer between the thermo-electric device and the controller.

Power generation system for gas-fired appliances

A method of assembling a pilot burner assembly for use with a gas fired appliance includes inserting a retention element of a gas supply line through a slot defined by a retaining ledge of a second bracket plate, rotating an outlet orifice of the gas supply line such that the second retention element engages the retaining ledge, and inserting a pilot guard through first and second pilot guard apertures defined by respective first and second bracket plates such that a retention element of the pilot guard cooperatively engages the retention element of the gas supply line to maintain a connection between the pilot guard and the gas supply line.

Method of assembling pilot burner assembly

A pilot burner assembly includes a bracket, a thermo-electric device configured to be connected to the bracket, and a unitary pilot guard. The bracket includes a first plate and a second plate spaced from the first plate. Each of the first and second plates have a pilot guard aperture defined therein. The pilot guard has a first end defining a gas inlet configured to receive a gas supply line, and a second end defining a gas outlet. The pilot guard includes an elongate body and a pilot hood disposed at the second end, and is configured be inserted into the pilot guard apertures. The pilot guard further includes a first retention element configured to cooperate with a second retention element on the gas supply line to maintain a connection between the pilot guard and the gas supply line.
