Lochinvar & A.O. Smith 100208365 Pilot Assembly

The Lochinvar & A.O. Smith 100208365 Pilot Assembly is a critical OEM ignition component engineered for high-recovery natural gas water heaters and commercial boilers. As a direct replacement for legacy part numbers PLT2908, PLT2908K, and 100165916, this intermittent pilot assembly is designed to integrate seamlessly with Lochinvar Solution (CB) and Copper-Pak (CP) series units. This assembly features a robust pilot burner and integrated flame sensor (thermocouple/thermopile logic) to ensure precise signal transmission to the ignition module, preventing gas flow in the event of a flame-out.

For service technicians, the 100208365 provides the exact physical dimensions and orifice sizing required to maintain the original intermittent pilot ignition (IPI) sequence. It is compatible with a wide range of models, including CWN399PM, CWN500PM, and the CB 045 to 260 boiler series. Utilizing genuine Lochinvar and A.O. Smith parts ensures that the combustion chamber maintains its factory-specified efficiency and safety parameters, reducing callbacks and diagnostic errors related to weak pilot signals or carbon buildup on the electrode.

Key Benefits

• OEM Precision: Drop-in replacement for 100208365, PLT2908, and PLT2908K to ensure proper mounting and electrode alignment.
• System Compatibility: Verified for use in Lochinvar CB, CP, CW, and A.O. Smith natural gas commercial platforms.
• Safe Ignition: Engineered for intermittent pilot systems, providing reliable arc-to-gas timing for immediate burner crossover.
• Durable Construction: High-temperature alloy components are built to withstand heavy-cycle commercial heating applications.
• Reduced Maintenance: Restores stable pilot flame geometry, minimizing soot accumulation and premature sensor failure.

Common Questions

Is the 100208365 compatible with LP (Propane) systems?
No, this specific assembly is calibrated for Natural Gas applications. Converting to propane requires the correct LP orifice and assembly to ensure proper BTU output and safe combustion.

Can I use this to replace the PLT2908K?
Yes, the 100208365 is the current manufacturer-recommended replacement for both PLT2908 and PLT2908K, maintaining identical technical specifications.

Does this assembly include the flame sensor and igniter?
Yes, this is a complete pilot burner assembly. It includes the necessary ignition and sensing components to restore the unit's pilot lighting sequence to factory standards.
