Lochinvar & A.O. Smith 100111369 Control Valve

The Lochinvar & A.O. Smith 100111369 Control Valve is a critical OEM natural gas control valve and thermostat assembly designed specifically for residential high-efficiency water heaters. Engineered for Hot Surface Ignition (HSI) systems, this component manages gas flow and temperature regulation with precision. Primarily utilized in Series 200 and 201 residential gas units, this replacement water heater gas valve ensures the burner operates within safe thermal parameters. It features integrated lead wires for direct connection to the igniter and sensor array, streamlining the installation process for field technicians. Compatibility includes 40 and 50-gallon power vent water heaters, common in modern HVACR applications requiring external combustion venting. Professionals should verify the manifold pressure and gas type before installation to maintain unit integrity. This technical-grade control is a direct replacement for legacy part numbers 186300-000 and 9006655005, providing a seamless fit for legacy GCV, GCVL, and XCV models without the need for extensive retrofitting.

Key Benefits for Technicians:

• Direct OEM Match: Prevents gas flow inconsistencies often found in aftermarket universal valves, ensuring the A.O. Smith gas valve meets factory flow specifications.
• Integrated Lead Wires: Simplifies wiring for Hot Surface Ignition systems, reducing time spent on-site during emergency repairs.
• Broad Model Compatibility: Validated for use in GCV-40, GCVL-40, XCV-40, GCV-50, and XCV-50 model ranges.
• Thermostatic Precision: Provides accurate temperature sensing to prevent overheating and ensure consistent hot water delivery.

Common Questions:

Is this valve compatible with Propane (LP) units?
No, the 100111369 is specifically calibrated for natural gas (NG) applications. Using this valve with Liquid Propane without a factory-approved conversion kit is hazardous.
