White-rodgers 36C03 300S1 Standing Pilot Gas Valve

Product Description

The WHITE-RODGERS 36C03 300S1 is a standing pilot gas valve designed for use in residential and light commercial heating appliances that rely on a continuous pilot flame for ignition. Operating on a 24-volt AC coil, this valve controls gas flow to the main burner and is compatible with both natural gas and liquid propane (LP) fuel types. It features a 1/2-inch inlet pipe connection and a 3/4-inch outlet pipe connection, along with an inlet pressure tap for field measurement and diagnostics. Licensed HVAC technicians and gas service professionals typically install this valve during routine maintenance or component replacement on standing pilot furnaces, boilers, and floor heaters.

This valve is suited for standing pilot heating systems in residential single-family and light commercial applications. It is commonly found in older furnaces, wall heaters, boilers, and unit heaters that do not use electronic ignition. The inlet pressure tap allows a technician to verify incoming gas pressure without removing the valve from the line. No side taps are included on this valve, which simplifies installation in tight equipment cabinets where side-tap fittings would interfere with adjacent components.

Key Features

• 24-volt AC coil voltage for compatibility with standard low-voltage thermostat control circuits
• Dual-fuel rated for natural gas and liquid propane (LP)
• 1/2-inch inlet x 3/4-inch outlet pipe sizing for direct inline replacement
• Inlet pressure tap included for in-line gas pressure verification
• Standing pilot valve type — no electronic ignition module required
• No side taps, reducing fitting clutter in compact equipment compartments

Compatibility

Designed as an OEM-style replacement standing pilot gas valve for residential and light commercial heating appliances using 24-volt AC control circuits with 1/2-inch inlet and 3/4-inch outlet pipe connections on natural gas or LP systems.

Installation Notes

Gas valve replacement must be performed by a licensed gas technician in accordance with local codes and the International Fuel Gas Code (IFGC). Shut off the main gas supply and disconnect 24-volt control wiring before removing the existing valve. Verify inlet gas pressure at the pressure tap after installation and confirm there are no leaks at all pipe joints using an approved leak-detection solution. Do not apply pipe thread sealant to the first thread of the inlet or outlet connections in a way that blocks internal gas ports.
