Lochinvar & A.O. Smith 100109286 Pilot Assembly

The Lochinvar & A.O. Smith 100109286 Pilot Assembly is a critical OEM replacement component engineered for high-recovery commercial water heaters and boilers. This 200 DEG C pilot assembly is designed to withstand extreme thermal stress within the combustion chamber, ensuring consistent pilot burner ignition and reliable flame rectification. As a genuine FVIR pilot assembly replacement, it restores factory-spec safety and performance to Flammable Vapor Ignition Resistant (FVIR) systems. This kit typically includes the pilot tube, high-temperature lead wires, and the orifice assembly required to maintain precise gas-to-air ratios. For contractors performing scheduled maintenance or troubleshooting flame signal dropouts, utilizing this specific Lochinvar water heater part ensures seamless integration with the existing gas valve and control module. Replacing a fouled or degraded assembly with the 100109286 prevents nuisance lockouts and ensures the burner transition remains smooth under high-demand cycles in demanding mechanical room environments.

• Thermal Durability: Rated for 200°C to prevent premature sensor failure and lead wire degradation in high-BTU applications.
• OEM Compatibility: Precision-fit for A.O. Smith, Lochinvar, and State commercial units, maintaining the integrity of the sealed combustion system.
• Optimized Flame Signal: Clean-burning pilot design minimizes carbon buildup on the electrode, reducing callbacks for ignition failure.
• Complete Setup: Includes necessary mounting hardware and tubing for efficient field installation.

What are the symptoms of a failing 100109286 pilot assembly?
Common indicators include erratic flame signals, repetitive ignition attempts followed by lockout, or visible soot accumulation on the pilot burner head, which disrupts the thermocouple or flame sensor circuit.

Is this pilot assembly compatible with both Natural Gas and Propane units?
This assembly is primarily configured for specific fuel types based on the orifice size. Always verify the orifice stamping to ensure it matches the manifold pressure and gas type of the HVACR equipment being serviced.

Does this kit include the pilot tubing?
Yes, the assembly typically includes the pre-bent pilot gas line and the necessary electrical connectors for the ignition controller.
