White-Rodgers 36C03-300 Gas Valve

The White-Rodgers 36C03-300 Gas Valve is a 24V single stage universal solution engineered for standing pilot systems. Designed for high-capacity throughput, this combination gas valve features a 1/2" x 3/4" NPT connection and provides a 230,000 BTU/HR rating, making it a reliable field replacement for the 624537 gas valve as well as numerous Intertherm, Nordyne, and Miller models. It includes a thermocouple-actuated line interrupter for 100% shut-off safety and ECO terminals for integration with limit controls.

The 36C03-300 comes factory-set for natural gas at 3.5" W.C. but includes an LP conversion kit for liquid propane applications. Its fast opening design ensures immediate burner ignition, while the adjustable regulator allows for precise gas valve pressure settings ranging from 2.5" to 5.0" W.C. for natural gas. This straight-through valve allows for versatile mounting from upright to 90 degrees in any direction, accommodating tight plenum spaces during service calls.
