Reznor 110852 Pilot Assembly

The Reznor 110852 Pilot Assembly is a critical replacement component designed specifically for standing pilot LP gas heating systems. Engineered for high-temperature environments, this LP gas pilot burner ensures stable flame rectification and consistent ignition cycles in compatible Reznor unit heaters. It features a durable nozzle design optimized for liquid propane combustion, preventing soot buildup and premature thermocouple failure. When a Reznor heater pilot light fails to stay lit or exhibits erratic flame patterns, replacing the entire standing pilot assembly is often more cost-effective than troubleshooting individual burner ports. This assembly is built to OEM specifications, ensuring proper pilot tube fitting alignment and orifice sizing for safe gas delivery. As a professional technician, ensuring the millivolt output remains within spec is vital for system reliability; the 110852 provides the precise flame geometry required to heat the thermocouple efficiently and maintain the safety circuit during heavy run cycles.

Key Benefits

• OEM Compatibility: Designed for seamless integration with Reznor gas-fired unit heaters requiring a standing pilot LP setup.
• Optimized LP Orifice: Specifically calibrated for liquid propane to ensure clean combustion and prevent clogged pilot burner issues.
• Rugged Construction: Built to withstand high-heat stress, reducing the frequency of service calls for pilot outages.
• Drop-in Replacement: Simplifies installation for contractors by matching factory mounting points and gas line connections.

Common Questions

Will this work for natural gas units?
No, the 110852 is specifically configured for LP gas units. Using it with natural gas will result in improper combustion due to the different orifice size and pressure requirements.

Does this assembly include the thermocouple?
This part number refers to the pilot burner assembly; technicians should verify if their specific maintenance kit requires a separate thermocouple or if the existing one is compatible with the mounting bracket.

What are the signs of a failing Reznor pilot assembly?
Common indicators include a yellow or lift-off flame, difficulty maintaining the pilot light, or visible corrosion on the burner head that disrupts the flame signal.
