Lochinvar & A.O. Smith 100208610 Gas Valve

The 100208610 Gas Valve is a direct replacement standing pilot gas valve designed for specific Lochinvar and A.O. Smith commercial water heaters and boilers. This critical fuel-path component, also identified by part numbers VAL2920 and VAL2920K, regulates gas flow to the burner assembly to ensure precise combustion cycles. As a specialized HVAC replacement part, it features a 1/2" NPT inlet and outlet configuration with a side tap for pilot tubing connection. It is engineered to manage manifold pressure effectively, maintaining stable operation in high-demand hydronic systems. When performing a water heater gas valve replacement, technicians must verify that the millivolt output from the thermocouple is sufficient to hold the electromagnetic coil open. This OEM gas control valve is built for durability in commercial mechanical rooms, providing a reliable solution for restoring pilot ignition systems. Proper gas valve troubleshooting during installation is required to confirm leak-free seals and correct gas pressure settings according to the appliance rating plate.

• Direct Compatibility: Exact fit for units requiring 100208610, VAL2920, or VAL2920K, eliminating the need for manifold modifications.
• Industrial Build Quality: Designed to withstand the high-temperature environments of commercial boiler rooms.
• Standard NPT Ports: Utilizes universal 1/2" piping connections for straightforward integration into existing gas trains.
• Reliable Pilot Control: High-precision internal diaphragm ensures consistent gas flow to the standing pilot assembly.

What are the symptoms of a failing 100208610 standing pilot valve?
Common indicators include the pilot flame failing to stay lit despite a functioning thermocouple, or the main burner failing to engage when the thermostat calls for heat due to internal coil failure.

Can this valve be used for Propane (LP) or Natural Gas?
This valve is typically configured for Natural Gas. Technicians must verify the specific gas type and orifice requirements of the appliance before installation, as using the wrong gas type can cause hazardous combustion issues.

Is the VAL2920K version different from the 100208610?
No, these part numbers are interchangeable. The 100208610 is the updated manufacturer part number that replaces the legacy VAL2920 and VAL2920K designations.
