Lochinvar & A.O. Smith 100111891 Gas Valve
The Lochinvar & A.O. Smith 100111891 Gas Valve is a critical OEM replacement part engineered for high-efficiency natural gas commercial water heaters and boilers. This K Series gas control valve is a direct replacement for obsolete part number 9007295005 and is essential for maintaining precise manifold pressure and air/gas mixtures within the combustion chamber. Designed for compatibility with the Lochinvar BTH series (including BTH-400 and BTH-500 models), this assembly ensures stable ignition control and consistent thermal efficiency. As a veterans in the field know, securing a genuine factory-authorized part is non-negotiable for system safety and avoiding the leakages or irregular firing associated with generic alternatives. The valve integrates seamlessly with the SMART SYSTEM control modules and existing venturi gaskets to optimize domestic hot water delivery in demanding commercial HVACR environments.
Key Benefits- Precise Gas Regulation: Maintains exact natural gas flow for optimal combustion efficiency and stable heater performance.
- Direct Cross-Reference: Serves as the factory-validated replacement for part 9007295005, ensuring electrical and physical compatibility.
- Enhanced System Safety: Redundant valve seating prevents gas migration, critical for high-output commercial boiler safety protocols.
- Durable OEM Build: Manufactured to original specifications for reliable operation in high-cycle HVAC recovery applications.
Is this valve compatible with Liquid Propane (LP) systems?
No, the 100111891 is strictly for Natural Gas (NG) configurations and should not be used on LP units without the appropriate factory-certified conversion kit.
Which Lochinvar and A.O. Smith models use this part?
This gas valve assembly is commonly found on Cyclone Xi and BTH-400/500 series models. Always verify your specific 104 series serial number before installation.
Does this include the replacement venturi gasket?
This SKU covers the gas valve assembly. It is professional best practice to inspect and replace the venturi gasket (e.g., 100146546) during installation to ensure a gas-tight seal.
