Reznor 110857 Pilot Assembly
The Reznor 110857 Pilot Assembly is a critical replacement component for natural gas unit heaters equipped with spark ignition systems. This OEM Reznor pilot is engineered to deliver reliable ignition for Reznor F and B series heaters, ensuring the flame sensor communicates accurately with the ignition module. Designed for NG pilot assembly applications, it features a precise orifice size and electrode spacing to maintain a stable pilot flame, even in high-demand industrial environments. Replacing a fouled or corroded pilot assembly is essential for preventing nuisance lockouts and ensuring efficient combustion cycles. For contractors performing preventative maintenance or emergency repairs, this assembly provides a direct-fit solution that eliminates compatibility issues often found with universal alternatives. When installing, ensure the high-voltage ignition lead is properly seated and the pilot tubing is inspected for obstructions to maintain peak performance on Reznor power vented heaters.
Key Benefits:- OEM Compatibility: Precision-fit for Reznor unit heaters to ensure seamless integration with the existing gas valve and control board.
- Optimized Ignition: Specifically designed for spark-to-pilot ignition sequences, reducing delayed ignition and burner noise.
- Durable Construction: Built with high-temperature alloys to withstand continuous thermal cycling in commercial heating applications.
- Direct Replacement: Eliminates the need for field modifications, saving labor time during residential or commercial service calls.
Does this assembly include the spark electrode?
Yes, the Reznor 110857 includes the electrode and sensor required for the spark ignition process.
Will this work for propane (LP) units?
No, this specific part number is calibrated for natural gas units. A localized orifice change or a specific LP assembly is required for propane conversions.
Why is my Reznor heater clicking but not lighting?
This often indicates a cracked ceramic insulator on the spark ignition pilot or a dirty sensor rod, making a complete pilot assembly replacement the most reliable fix.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
