White-rodgers 36C03 433S1 Standing Pilot Gas Valve

Product Description

The WHITE-RODGERS 36C03 433S1 is a standing pilot gas valve designed for use in residential and light commercial heating appliances. Operating on a 24 volt AC coil, it controls gas flow in natural gas and liquid propane (LP) systems that use a standing pilot ignition arrangement. The valve features 3/4 inch inlet and outlet pipe connections, an inlet pressure tap, and side taps, making it compatible with a variety of installation configurations. Licensed HVAC technicians and gas appliance service technicians are the primary installers of this component.

This gas valve is suited for standing pilot furnaces, boilers, wall heaters, and similar gas-fired appliances that require a 24 volt control circuit. The inlet pressure tap allows field verification of supply gas pressure without disturbing the line connection. Side taps provide convenient access points for manifold pressure measurement or additional control wiring as required by the appliance manufacturer. It is appropriate for both natural gas and LP fuel types, making it a versatile replacement option across a range of heating equipment.

Key Features

• 24 volt AC coil voltage compatible with standard low-voltage thermostat control circuits
• 3/4 inch x 3/4 inch pipe connections for direct inline installation
• Inlet pressure tap included for field gas pressure verification
• Side taps provided for manifold pressure measurement access
• Compatible with both natural gas and liquid propane (LP) fuel types

Compatibility

Designed as an OEM-style replacement standing pilot gas valve for residential and light commercial gas-fired heating appliances requiring a 24 volt coil and 3/4 inch pipe connections on natural gas or LP systems.

Installation Notes

Installation must be performed by a licensed HVAC technician or qualified gas service professional in accordance with applicable local codes and the International Fuel Gas Code (IFGC). Shut off the gas supply at the upstream shutoff valve and disconnect electrical power to the appliance before removing the existing valve. Verify supply gas pressure at the inlet tap after installation to confirm proper operating conditions. Do not exceed the valve's rated inlet pressure and ensure all pipe connections are leak-tested with an approved solution before returning the appliance to service.
