Lochinvar & A.O. Smith 100187872 Gas Valve
The Lochinvar & A.O. Smith 100187872 Gas Valve is an OEM Natural Gas Valve/Venturi Assembly designed for high-efficiency water heating systems. This critical component integrates the gas control valve and the venturi into a single, high-performance unit to ensure precise fuel-to-air ratios for optimal combustion. Engineered for A.O. Smith Cyclone and Lochinvar Armor series equipment, the 100187872 assembly eliminates the need for a traditional manifold gas line by flanging directly to the blower assembly. This replacement gas valve features an internal microprocessor for tighter differentials and enhanced operating parameters, ensuring the burner maintains consistent performance even under varying load conditions. For technicians, this genuine OEM part is the standard solution for resolving ignition failures, rough starting, or inconsistent flame signals in high-BTU condensing water heaters.
Key Benefits
- Direct Fit Integration: The combined gas valve and venturi assembly ensures seamless installation and maintains factory-specified combustion integrity.
- Precision Gas Regulation: Advanced internal microprocessor control provides accurate sensing and faster heating response times for high-efficiency operation.
- System Dependability: Designed as a specific Lochinvar replacement part to restore safe gas flow and prevent lockouts caused by off-ratio combustion.
- Rugged Construction: Built to withstand the demands of commercial HVACR environments, ensuring reliable gas flow regulation over the long term.
Common Questions
Does this assembly include the gas orifice and gasket?
Yes, the 100187872 is typically supplied with the gas orifice and required seals to ensure a leak-proof connection to the blower flange.
Can I use this valve for Liquid Propane (LP) conversion?
No, this specific part number is configured strictly for Natural Gas (NG) applications. Using this on an LP system without a manufacturer-approved conversion kit is hazardous.
What are the symptoms of a failing venturi assembly?
Common indicators include ignition failure, audible "rumbling" or rough operation during startup, and frequent "FLAME LOSS" or "CHECK IGNITER" error codes on the system controller.
