Lochinvar & A.O. Smith 100111381 Pilot Assembly
The Lochinvar & A.O. Smith 100111381 Pilot Assembly is a high-precision OEM component specifically engineered for Liquid Propane (LP) water heaters. Designed for the 200 and 201 series, this assembly is a direct replacement for HSI control valves in 40 and 50-gallon residential units. As a veteran-grade LP pilot assembly with tubing, it ensures reliable pilot flame rectification and consistent ignition cycles, preventing common lockout issues associated with worn igniter-sensor probes. When troubleshooting "no hot water" calls, this kit provides the precise orifice diameter and thermocouple signal required for the Smart System control boards found in modern Lochinvar and A.O. Smith water heaters. Proper seating of the included aluminum pilot tubing is critical to maintain the FVIR system integrity and prevent flash-back. For contractors, 100111381 is the definitive solution for restoring LP gas combustion performance in GCV, XCV, and GVR model families without the risk of non-compliant aftermarket HVAC parts.
Key Benefits for Technicians- OEM Compatibility: Exact fit for A.O. Smith 100111381 and Lochinvar 100111381, eliminating field modifications.
- Comprehensive Kit: Includes the LP pilot burner, HSI igniter, and pre-bent pilot tubing for immediate installation.
- Combustion Stability: Engineered for Liquid Propane settings to yield a stable, blue pilot flame for fast sensor response.
- System Safety: Restores factory-spec flame sensing to prevent unburned gas accumulation and control board error codes.
Will this work for Natural Gas units? No, this assembly is strictly for Liquid Propane (LP). Installing this on a Natural Gas heater will cause dangerous combustion imbalances due to the LP orifice sizing.
Are the gaskets included with the assembly? This kit primarily features the pilot bracket and tubing; always inspect the burner door gasket and replace if the seal is compromised during the HVAC repair.
What models does the 100111381 fit? It is verified for Series 200/201 models including GCV-40, XCV-50, GVR-40, and XGV-50 residential water heaters.
