Lochinvar & A.O. Smith 100171540 Gas Valve
The Lochinvar & A.O. Smith 100171540 Gas Valve is a high-capacity dual automatic gas control engineered for intermittent pilot systems in residential and light commercial heating applications. This Honeywell VR8404P series valve features a 24V, 60Hz solenoid-operated design with a straight-through body pattern, ensuring reliable fuel regulation for high-demand HVACR equipment. Designed with a fixed pressure regulator and 1/8 inch NPT pressure taps, it allows technicians to verify inlet and manifold pressures accurately during commissioning. As a non-convertible gas valve, it is purpose-built for specific fuel types (Natural Gas) and provides a safety shutoff with dual automatic operators. This replacement gas valve is essential for maintaining the combustion efficiency of Lochinvar boilers and A.O. Smith water heaters, integrating seamlessly with S8600 series ignition modules to provide Class A safety shutoff and precise pilot gas flow control.
Key Benefits- High-Capacity Performance: Rated for up to 720 ft³/hr, making it suitable for larger residential and commercial burners.
- Dual Automatic Operators: Provides redundant safety shutoff to prevent gas leaks and ensure secure operation.
- Technical Precision: Equipped with accessible 1/8" NPT inlet and outlet pressure taps for streamlined field diagnostics.
- Rugged Temperature Rating: Built to operate in ambient environments ranging from -40°F to 175°F.
- Standardized Integration: Features 1/4" quick-connect terminals for fast wiring to 24V control circuits.
Is the 100171540 gas valve convertible between Natural Gas and LP?
No. The Honeywell VR8404P is a fixed-regulation valve and is not field-convertible. You must ensure the valve matches the fuel source of the appliance.
What are the symptoms of a failing VR8404P gas valve?
Common indicators include the burner failing to ignite despite a spark, the valve clicking but not opening, or an ignition fault code on the Lochinvar SMART SYSTEM board. Always verify that 24V power is reaching the valve terminals before replacing.
Does this valve include the manifold?
Yes, this specific part number is a Dual Gas Valve with Manifold assembly, designed for direct fit in compatible Lochinvar and A.O. Smith units.
