Williams P322399 Pilot Assembly

The Williams P322399 Pilot Assembly is a high-performance LP gas pilot burner engineered specifically for propane-fired Williams Gravity Direct Vent Wall Furnaces. Designed to replace the legacy part P179600, this genuine OEM component is critical for maintaining consistent burner ignition and system safety. It features a 90-degree left design and comes integrated with a thermopile generator, pilot tube, and orifice, ensuring seamless voltage output to the gas valve. This assembly is compatible with 14,000, 22,000, and 30,000 BTU models, including the 1403821, 2203821, and 3003821 series. For professional contractors, this replacement pilot assembly offers a precise fit to resolve common millivolt system failures, such as pilot outages or delayed main burner ignition. Note that the P142700 gasket is sold separately and should be replaced during installation to maintain the integrity of the combustion chamber seal.
