Williams P501617 Pilot Assembly

The Williams P501617 Pilot Assembly is the definitive OEM replacement for aging or failed ignition components in Williams Floor Furnaces. This Natural Gas pilot assembly is purpose-built for compatibility with the 4505A and 6505A series, providing a precise mechanical fit that eliminates the need for field modifications. As the direct successor to the P323411, this assembly addresses common furnace ignition problems by utilizing a high-grade thermopile and thermocouple interface designed to maintain a stable pilot flame even in varying pressure conditions. Its construction ensures dependable performance across all elevations, crucial for HVAC contractors servicing high-altitude installations. By installing this genuine Williams furnace part, you restore the specific millivolt signal required for the main gas valve to cycle safely. Maintaining the integrity of the pilot burner is essential for preventing nuisance service calls and ensuring the long-term operational efficiency of the floor furnace system.

• Universal Elevation Performance: Engineered to provide consistent natural gas ignition without flame lifting or carboning at high altitudes.
• Direct OEM Specification: Verified P501617 component that bypasses the reliability issues associated with generic, non-branded HVAC replacement parts.
• Backwards Compatibility: Engineered as a drop-in replacement for the legacy P323411, ensuring zero-clearance issues during retrofits.
• Optimized Service Life: Features durable shielding to protect the sensing elements from excessive thermal stress within the combustion chamber.

What models can use the P501617 pilot assembly?
This assembly is specifically calibrated for Williams Floor Furnaces models 4505A and 6505A. It is not intended for use with Liquid Propane (LP) units without a conversion kit.

Does this replace the P323411 pilot?
Yes, the Williams P501617 is the official direct replacement for part number P323411, offering improved ignition stability and updated metallurgical standards.

Is this compatible with millivolt systems?
Correct. This natural gas pilot burner generates the necessary millivoltage to operate the gas valve, making it the standard choice for non-electric ignition floor furnace models.
