White-Rodgers 36C01A-405 Gas Valve

The White-Rodgers 36C01A-405 Gas Valve is a technical-grade standing pilot gas valve designed for heavy-duty furnace gas valve replacement in residential and light commercial heating systems. Operating on a 120V gas valve circuit with a 0.23 Amp draw, this 3/4" x 3/4" NPT combination control integrates a manual gas cock, pilot safety, and a fast-open pressure regulator into a single, compact manifold. It provides a high flow capacity of approximately 280,000 BTU for natural gas (at 1" W.C. pressure drop), making it a versatile HVAC gas valve replacement for older standing pilot boilers and unit heaters. The unit features built-in White-Rodgers 36C01A-405 troubleshooting ports with a 1/8" NPT pressure tap for accurate manifold checks and a 1/4" compression fitting for the pilot line. Included with the 36C01A-405 is an LP conversion kit (F92-0866) and three reducer bushings, enabling immediate field adaptation from natural gas to propane gas valve configurations.

• Universal Compatibility: Includes two 3/4" to 1/2" and one 1/2" to 3/8" reducer bushings to fit a wide range of manifold sizes.
• Flexible Mounting: This multi-function control can be mounted in any orientation except upside down, simplifying retrofits in tight cabinets.
• Convertible Logic: Standard 3.5" W.C. natural gas regulator setting is field-adjustable from 2.5" to 5.0" W.C.
• Complete Installation Kit: Ships with the F92-0866 LP conversion kit, allowing for high-pressure regulator settings of 4.2" to 11.0" W.C.
• Reliable Pilot Safety: The redundant solenoid design ensures positive shut-off and safe standing pilot operation in demanding environments.

Can I use this valve for HSI or DSI ignition systems?
No, the 36C01A-405 is specifically engineered for standing pilot systems where a continuous flame is present. For Hot Surface Ignition (HSI) or Direct Spark Ignition (DSI), a different 36C series model without the manual pilot gas cock is required.

What is the purpose of the 'plugged pilot' feature?
The pilot outlet comes plugged from the factory to protect the internal seals. For installation, simply remove the 1/4" plug to connect your pilot tubing. If you're replacing a 36C01A-284, this valve is the direct technical successor.

Does this valve handle high-pressure environments?
The maximum inlet pressure is 0.5 PSI (14.0" W.C.). If your supply pressure exceeds this, an external regulator must be installed upstream to prevent damage to the valve diaphragm.
