Copeland Comfort Control (White Rodgers) 36H33-412 Gas Valve

The Copeland Comfort Control (White Rodgers) 36H33-412 is a professional-grade 3/4 inch slow-open gas valve engineered for high-demand residential and commercial heating applications. This 24V gas valve is designed for natural gas systems, providing precise regulation with a factory setting of 3.5" W.C., though it is field-adjustable to meet specific manifold pressure requirements. The slow-open characteristic is critical for technical setups requiring controlled ignition, as it prevents pressure surges and ensures a smooth transition to steady-state combustion. As a versatile White Rodgers 36H replacement, this unit features a high-capacity flow rate and a compact footprint, making it the standard choice for technicians servicing multi-stage or high-efficiency furnaces and boilers. It serves as a direct drop-in for multiple legacy models, including 12826-06S, B1282606, and 28W66, ensuring seamless integration with existing 24V control circuits and burner assemblies.

• Universal Compatibility: Serves as a direct replacement for 36E24-214, 36E52-214, 36E98-304, and 025-30888-000.
• Optimized Ignition: Slow-open gas valve design reduces noise and mechanical stress during the startup cycle.
• High Flow Capacity: 3/4" x 3/4" NPT inlet/outlet supporting large BTU inputs for commercial and residential hardware.
• Field Practicality: Includes clear terminal markings for 24V wiring and accessible pressure taps for accurate manometer readings.
• Reliable Regulation: Maintains consistent natural gas manifold pressure to ensure stable burner flames and efficient fuel consumption.

What is the primary application for the 36H33-412?
It is primarily used in natural gas heating systems that require a slow-opening 24V redundant valve to manage burner ignition and gas flow safety.

Can this valve be converted for Propane (LP) use?
While optimized for natural gas (2.1" to 3.5" W.C.), these valves can typically be converted using a manufacturer-approved LP conversion kit to reach 9" W.C. requirements.

Why use a slow-open valve instead of a fast-open model?
Technicians specify slow-open valves like the 36H33-412 to eliminate "delayed ignition" issues and combustion rumble, providing a safer and quieter startup sequence.
