Williams P323700 Pilot Assembly

The Williams P323700 Pilot Assembly is the definitive OEM replacement for Williams wall furnaces, specifically engineered for Gravity Direct Vent systems using Natural Gas. Operating as a critical millivolt ignition system component, this assembly replaces the legacy part number P179500. It is built to interface seamlessly with the Williams 1403822 (14,000 BTU) model, ensuring the thermopile generates the precise millivoltage required to hold the gas valve open and maintain a stable pilot flame.

When troubleshooting standing pilot furnace ignition issues or erratic flame sensing, replacing the entire assembly is often more efficient than manual cleaning or component-level repairs. This Williams P323700 includes the orifice and generator lead wires, though technicians should note that the P142700 gasket is sold separately. By restoring the correct pilot burner geometry, you eliminate nuisance dropouts and ensure the direct vent furnace maintains high combustion efficiency throughout the heating season.

Key Benefits:

• Direct OEM Fit: Ensures exact alignment for Williams Gravity Direct Vent Wall Furnaces, bypassing the safety risks associated with universal aftermarket pilots.
• Superior Millivolt Output: The integrated pilot generator produces a consistent electrical signal to prevent unintended gas valve closures.
• High-Temperature Durability: Constructed with heavy-duty metals to resist oxidation and thermal stress in high-cycle environments.
• Streamlined Installation: Pre-configured for natural gas wall furnaces, reducing labor time during service calls.

Common Questions:

Is the Williams P323700 compatible with Propane (LP) models?
No, this specific assembly is configured for Natural Gas. For LP units, a different orifice and assembly are required to match the higher pressure and BTU characteristics of propane.

Does this unit replace the P179500?
Yes, the P323700 is the current manufacturer-certified successor to the P179500. It maintains the same mounting footprint and electrical specifications.

Why is my pilot flame orange instead of blue?
An orange flame usually indicates carbon buildup or a partially clogged orifice. Replacing the assembly with a new Williams P323700 restores the correct air-to-gas ratio for a clean, blue, high-energy flame.
