White-Rodgers 36C03-400 Gas Valve

The White-Rodgers 36C03-400 Gas Valve is an industry-standard universal standing pilot gas valve designed for high-capacity heating applications. As a veteran-grade 24V combination gas valve, it integrates a manual valve, pilot safety system, and pressure regulator into a single compact housing. This unit features a 3/4" x 3/4" NPT inlet and outlet, making it compatible with larger residential and light commercial furnaces or boilers. With a straight-through flow design and a high capacity rating of up to 280,000 BTU/HR, this fast-opening gas valve ensures reliable gas flow management. The 36C03-400 is factory-set for natural gas at 3.5" W.C. but includes a LP conversion kit for field versatility. Specifically engineered for thermocouple-actuated line interrupter systems, it provides 100% shut-off safety, ensuring the main burner cannot engage without a verified pilot flame. For contractors, the inclusion of reducer bushings (3/4" to 1/2") allows for flexible field adjustments during retrofits.

Key Benefits:

• Universal Compatibility: Serves as a versatile replacement for most standing pilot gas valves using a 30mV thermocouple.
• High Capacity Performance: Rated for up to 280,000 BTU/HR, suitable for high-demand HVAC gas valve applications.
• Field Convertible: Includes all necessary hardware for natural gas to liquid propane conversion to match site requirements.
• Flexible Installation: Multi-position mounting capability (upright to 90 degrees) facilitates easier fitment in tight cabinets.
• Integrated Safety: Features a 100% shut-off automatic pilot to prevent gas buildup in the event of pilot outage.

Common Questions:

Can this valve be used on 750mV millivolt systems?
No, this specific model is a 24VAC gas valve. For power-pile or self-generating systems, you must use the 750mV rated equivalent to ensure proper solenoid actuation.

Does this unit support electronic ignition (HSI/DSI)?
This is a standing pilot valve only. It is not designed for direct spark or hot surface ignition systems. Use the White-Rodgers 36E or 36J series for those specific ignition profiles.

What is the maximum pressure rating for this valve?
The 36C03-400 is rated for a maximum inlet pressure of 1/2 PSI (14.0" W.C.), which is standard for residential and light commercial gas manifolds.
