Lochinvar & A.O. Smith 100092742 Control Valve

The Lochinvar & A.O. Smith 100092742 Control Valve is a critical OEM replacement gas valve engineered specifically for natural gas water heaters and boilers. Designed for pre-FVIR power vent units, this combination gas valve manages the intricate balance of fuel delivery and safety. It functions as the primary regulator for the gas burner assembly, ensuring precise temperature regulation and consistent ignition control. By integrating an internal microprocessor, this valve provides high-accuracy sensing and faster response times, which are essential for maintaining high-efficiency system performance and reducing exhaust waste.

For service technicians, the 100092742 is the standard solution for resolving common "no-heat" calls related to pilot ignition failure or erratic flame behavior. This natural gas control valve is a genuine factory-spec component, ensuring native compatibility with original A.O. Smith and Lochinvar manifolds without the need for field modifications. Its construction is optimized for central heating environments where reliable manifold pressure management is necessary to prevent thermal switch trips and long-term hardware fatigue.

• Precise Gas Flow Regulation: Maintains consistent manifold pressure for stable burner operation and improved energy efficiency.
• Enhanced System Safety: Built-in ignition control logic prevents incomplete combustion and manages redundant safety shut-offs.
• OEM Compatibility: Specifically calibrated for Lochinvar and A.O. Smith pre-FVIR power vent models, ensuring a drop-in 1:1 replacement.
• Self-Diagnostic Capability: Designed to interface with modern electronic monitoring systems to identify ignition failures quickly.
• Durable Construction: Engineered to withstand the rigors of high-demand water heater and boiler service environments.

• Does this valve support Propane (LP) conversion? No, this is a dedicated natural gas control valve. Use only with NG systems as specified by the equipment nameplate.
• Will this fix a pilot light that won't stay lit? While this valve regulates the pilot ignition process, technicians should also verify the thermocouple voltage and thermal switch status before replacement.
• Is this compatible with newer FVIR (Flame Guard) units? This specific part number is designed for pre-FVIR power vent units. Always cross-reference the serial number to ensure exact fitment.
