Lochinvar & A.O. Smith 100093756 Pilot Assembly

The Lochinvar & A.O. Smith 100093756 is a professional-grade Propane LP Pilot Assembly engineered for precision ignition in residential and commercial high-efficiency water heaters. This OEM replacement part is critical for restoring the flame rectification circuit, ensuring the pilot burner consistently provides a reliable source for main burner ignition. Designed specifically for liquid propane (LP) systems, this assembly integrates a high-output thermocouple and durable pilot tubing to maintain system safety and prevent nuisance lockouts caused by weak pilot signals or carbon fouling. As a genuine Lochinvar service part, it meets exact factory specifications for gas orifice sizing and bracket alignment, which is vital for maintaining the heat exchanger's operational integrity. Whether you are performing routine maintenance or a full gas water heater repair, using this 100093756 pilot assembly ensures seamless compatibility with existing A.O. Smith gas valves and control modules, reducing diagnostic time and streamlining the installation process for field technicians.

• Precise LP Orifice: Factory-calibrated specifically for liquid propane to ensure stable flame characteristics and optimal ignition performance.
• OEM Compatibility: Exact fit for Lochinvar and A.O. Smith units, including select BTX-100 and GDHE-50 series models, eliminating the need for field modifications.
• Integrated Components: Includes the pilot burner and thermocouple to provide a complete solution for pilot assembly replacement in gas-fired systems.
• Professional Durability: Built to withstand high-temperature combustion environments, reducing the frequency of heating system maintenance.

• Is this assembly compatible with natural gas units? No, the 100093756 is strictly for Propane LP applications; using it with natural gas can lead to improper combustion and hazardous operation.
• What are the symptoms of a failing pilot assembly? Common indicators include a pilot flame that will not stay lit, orange/sooty flames, or a water heater failing to trigger the main burner due to low millivolt output from the thermocouple.
• Does this include the pilot orifice? Yes, this is a complete pilot burner assembly designed to be a drop-in replacement for the original OEM component.
