Williams P323648 Burner

The Williams P323648 Burner is a precision-engineered OEM replacement burner designed for high-performance combustion in Williams Monterey Top Vent and Forsaire Direct Vent furnaces. As a critical lead-free component for the 250, 350, and 500 Series furnaces, this burner with pilot bracket ensures optimal flame stability and thermal efficiency. Field-verified as the direct substitute for the legacy Williams 12B56 burner, it features a rugged, corrosion-resistant construction built to withstand the high-temperature demands of residential and commercial HVAC furnace repair. The integrated pilot assembly bracket simplifies the alignment of the ignition source, reducing labor time during gas furnace burner replacement for technicians. Whether you are servicing a single-burner 250/350 model or a dual-burner 500 Series unit, the P323648 provides the exact porting and BTU output required to restore factory-spec heat exchange performance without the risks associated with aftermarket "universal" alternatives.

• Exact OEM Fit: Drop-in replacement for the Williams 12B56, eliminating the need for field modifications or manifold adjustments.
• Versatile Application: Fully compatible with Monterey Top Vent and Forsaire Direct Vent heating systems.
• Reliable Ignition: Pre-welded pilot bracket ensures perfect thermopile and pilot light positioning for consistent startups.
• Durable Construction: Heavy-gauge material resists warping and port clogging, maintaining a clean combustion process over time.

Is the P323648 compatible with natural gas or LP units?
This burner is typically configured for the appliance's specific gas type; however, it is the standard replacement burner used in both natural gas and liquid propane Williams furnace assemblies when paired with the correct orifice.

How many burners are required for a Williams 500 Series furnace?
While the 250 and 350 Series use a single burner, the higher-output 500 Series models typically require two P323648 units for a full manifold overhaul.

Does this include the pilot assembly itself?
No, this part is the burner with pilot bracket. The pilot burner, thermopile, and tubing are sold separately or as part of a different pilot kit.
