Lochinvar & A.O. Smith 100109365 Control Valve

Upgrade or maintain your water heating system with the Lochinvar & A.O. Smith 100109365 Natural Gas Control Valve. This genuine OEM component is the direct updated version for 9003638105 and replaces the legacy model 182791-005. Engineered specifically for residential and light commercial natural gas applications, this combination gas valve features a precise 4.0" W.C. manifold pressure setting to ensure optimal burner performance and efficiency. It incorporates a critical ECO (Energy Cut-Off) safety switch calibrated to 195°F, providing essential over-temperature protection for the tank.

Designed for professional installation, this thermostatic gas valve manages both the pilot flame and main burner flow. The fixed pilot pressure and 160°F maximum temperature rating make it a reliable choice for HVAC contractors servicing A.O. Smith and Lochinvar units. Utilizing this OEM replacement gas control valve ensures the unit maintains its original specifications and combustion characteristics, preventing common issues like pilot outage or improper manifold pressure often associated with generic alternatives.

• OEM Compatibility: Successor to part numbers 9003638105 and 182791-005, ensuring a perfect fit and factory-spec performance.
• Integrated Safety: Features a built-in ECO high-limit switch that interrupts gas flow if water temperatures exceed safe operating limits.
• Factory Calibrated: Pre-set to 4.0" W.C. for stable natural gas delivery to the main burner assembly.
• Genuine Reliability: Built by the original manufacturer to withstand the thermal cycling of high-demand water heating environments.

• Is this valve compatible with LP (Propane) units? No, current 100109365 specifications are strictly for natural gas applications with a 4.0" W.C. manifold setting.
• When should I replace the control valve? Typical indicators include a pilot that won't stay lit despite a healthy thermopile, or a main burner failing to ignite when the thermostat calls for heat.
• Does this include the thermopile? This SKU is the control valve assembly; verify if your specific repair requires a separate thermopile or igniter kit.
