Lochinvar & A.O. Smith 100208366 Pilot Assy

The Lochinvar & A.O. Smith 100208366 is a professional-grade Natural Gas Standing Pilot Assembly designed for high-performance residential and commercial water heaters. This critical ignition component is a direct, drop-in replacement for obsolete part numbers PLT2016 and PLT2016K, as well as the older 100165894. Engineered to meet the exacting standards of original equipment manufacturers, this assembly ensures consistent pilot flame stability, which is essential for reliable main burner ignition and overall system safety.

When troubleshooting a water heater pilot light won't stay lit issue, veteran techs know that carbon buildup or a failing thermocouple within the assembly is often the culprit. The 100208366 features a robust thermocouple and pilot tube configuration that maintains the millivolt signal required to hold the gas valve open during heating cycles. Its durable construction is optimized for the high-heat environment of Lochinvar and A.O. Smith gas water heaters, providing the technical precision needed to restore hot water service quickly and reduce costly callbacks on the job site.

• Exact OEM Replacement: Seamlessly replaces PLT2016 and PLT2016K without the need for field modifications.
• Broad Compatibility: Verified for use in various Lochinvar and A.O. Smith natural gas models, including CWN399PM and CWN500PM.
• Optimized Ignition: Provides a steady standing pilot flame to ensure efficient burner cross-lighting and peak performance.
• Complete Assembly: Includes the pilot burner, thermocouple, and requisite fittings for a streamlined gas water heater repair.

• How do I confirm if this pilot assembly fits my specific water heater model? Check your data plate for the part number or verify against the 100208366 cross-reference list for PLT2016 or 100165894.
• Can I use this assembly with Propane (LP) units? No, the 100208366 is specifically calibrated for Natural Gas pilot assembly applications and should not be used with LP gas.
• Why is my pilot flame orange instead of blue? An orange flame often indicates a clogged pilot orifice or improper air-to-gas mixture; replacing the entire standing pilot assembly typically resolves these combustion issues.
