Lochinvar & A.O. Smith 100165830 Pilot Assembly

The Lochinvar & A.O. Smith 100165830 Pilot Assembly is a critical combustion component engineered specifically for LPG Gas (Propane) water heaters and boilers. Designed for precise ignition in residential and light commercial systems, this assembly ensures a stable pilot flame is maintained to safely light the primary burner. As a direct replacement part for various Lochinvar and A.O. Smith models, including the BFL, ES, and ET series, the 100165830 features a durable construction that withstands high-temperature combustion environments. It integrates seamlessly with the existing gas control valve and thermocouple leads to prevent ignition failure lockouts caused by weak flame signals. For technicians performing routine maintenance or troubleshooting blocked orifices, this assembly provides the necessary pilot burner pressure (typically 10.0" W.C. for LPG) to maintain system efficiency. Utilizing a high-quality flame sensor and electrode configuration, it provides consistent spark-to-flame performance, ensuring the sealed combustion chamber operates within OEM specifications.

Key Benefits for HVACR Contractors

• Direct OEM Compatibility: Engineered as a precision fit for Lochinvar 100165830 and A.O. Smith 100165830 specifications, reducing field modification time.
• Application Specific: Calibrated strictly for LPG Gas systems, ensuring correct orifice sizing and fuel-to-air ratios for propane applications.
• Reliable Ignition: Features a robust electrode design to eliminate common ignition failure issues and "no hot water" service calls.
• Durable Construction: Built with high-grade alloys to resist oxidation and carbon buildup on the pilot hood and sensor.

Common Questions

Is the 100165830 pilot assembly compatible with Natural Gas units?
No, this specific assembly is designed and calibrated only for LPG Gas (Liquid Propane). Using it with natural gas will result in improper combustion and potential safety hazards.

What are the signs that this pilot assembly needs replacement?
Common indicators include a pilot that won't stay lit, yellow/lazy flames, or "Ignition Failure" fault codes on the water heater's diagnostic display. These often stem from a cracked ceramic insulator or a fouled flame sensor.

Does this assembly include the thermocouple or flame sensor?
Yes, this is a complete pilot burner assembly that typically includes the pilot tube, electrode/sensor, and mounting bracket to ensure a comprehensive repair of the ignition pilot circuit.
