Reznor 110855 Pilot Assembly

The Reznor 110855 Pilot Assembly is a critical OEM replacement component designed for high-performance natural gas unit heaters. As a dedicated NG Pilot Assembly Standing Pilot, this part provides the consistent, stable ignition source required to maintain safe and efficient burner operation in industrial and commercial HVAC systems. This assembly is engineered specifically for Reznor's standing pilot configurations, where a reliable continuous flame is necessary to prevent nuisance lockouts and ensure the main gas valve opens correctly upon a call for heat.

Constructed with high-heat resistant alloys and precision-machined orifices, the Reznor 110855 includes the necessary pilot burner and mounting bracketry for a direct-fit installation. It is specifically calibrated for Natural Gas pilot ignition, ensuring optimized fuel-to-air mixture for a strong, blue flame that maintains proper thermocouple/thermopile voltage. When troubleshooting unit heater ignition failure, replacing an aged or clogged pilot assembly is often the primary solution to restore system reliability. This component is compatible with a wide range of Reznor gravity-vented and power-vented units utilizing a standing pilot gas valve.

Key Benefits

• OEM Precision: Genuine Reznor replacement part ensures exact mounting alignment and orifice sizing compared to universal alternatives.
• Enhanced Safety: Provides a stable flame to ensures the gas valve circuit remains energized during operation.
• Durability: Built with robust materials to withstand constant thermal cycling in high-demand heating environments.
• Natural Gas Optimized: Precision-drilled orifice specifically for NG combustion, preventing soot buildup and pilot outages.

Common Questions

How do I know if my Reznor pilot assembly needs replacement?
If the pilot flame is weak, yellow, or lifting off the burner, or if the system fails to stay lit after the 30-second thermocouple hold period, the Reznor 110855 may be clogged or damaged and requires replacement.

Is this part compatible with Propane (LP) units?
No, this specific assembly is for Natural Gas applications only. Using an NG pilot assembly on an LP system can cause dangerous combustion issues due to the different orifice size requirements.

Does this assembly include the thermocouple?
This item is the pilot burner assembly; it is best practice to verify the condition of your existing thermocouple or thermopile and replace it simultaneously to ensure the entire ignition circuit is refreshed.
