Reznor 110851 Pilot Assembly

The Reznor 110851 Pilot Assembly is a critical replacement component designed for standing pilot gas valves on various Reznor unit heaters. Engineered for natural gas (NG) applications, this assembly ensures consistent ignition and reliable flame sensing for older generation heating equipment. Specifically utilized in Reznor F-series and Reznor B-series furnace models, this replacement pilot burner is essential for maintaining the thermocouple position relative to the main burner. It includes the necessary hardware for mounting and pilot orifice alignment to ensure a stable pilot flame. Technicians should verify millivolt output and ensure the pilot line connection is secure to prevent nuisance lockouts. This OEM-spec part provides the precision required to meet original equipment standards for HVAC unit heater ignition systems, making it a direct fit for Reznor heating system maintenance and repair projects.

• Direct OEM Fit: Engineered specifically for compatibility with legacy Reznor standing pilot configurations.
• Reliable Ignition: Maintains precise flame geometry for optimal thermocouple heating and valve activation.
• Durable Construction: Built to withstand high-temperature environments within the combustion chamber.
• Simplified Service: Facilitates rapid restoration of heating cycles in natural gas unit heaters.

Is this pilot assembly compatible with propane (LP) units?
No, the 110851 is calibrated with a natural gas pilot orifice. For propane applications, a specific LP conversion or dedicated LP pilot assembly is required.

Does this assembly include the thermocouple?
This part number typically refers to the pilot burner assembly; technicians should inspect the existing thermocouple and lead wires during installation to determine if they also require replacement.

Which Reznor models use the 110851?
It is widely used in Reznor F, FM, B, and BE models that utilize a standing pilot rather than electronic spark ignition.
