Abstract:
A piezoelectrically-ignited gas appliance comprising:a fuel regulator assembly having a fuel intake port removably attachable to a source of fuel, a fuel output port, and a valve mechanism separating the fuel intake port and fuel output port;a burner assembly includinga transfer pipe assembly having a proximal end and a distal end,an air/fuel mixing assembly having an air opening formed at the proximal end and a fuel injector formed at the fuel output port within the proximal end, anda combustion assembly having a combustion nozzle and a combustion flange attached to the distal end; anda piezoelectric ignition assembly including a piezoelectric charge generator coupled by a thermally and electrically-insulated, semi-rigid conductive wire within the transfer pipe assembly to an electrode having a stripped tip protruding from a terminal branch midway along the transfer pipe assembly, the generator and burner assembly being electrically grounded, the wire forming a bent part having at least two bends bracing the wire against the transfer pipe assembly prior to forming the terminal branch, the terminal branch extending away from the transfer pipe assembly so as to properly distance the stripped tip from the transfer pipe assembly.
