Carrier EF34CW246 Gas Valve

The Carrier EF34CW246 is a robust, single-stage 24V natural gas valve designed for high-performance regulation in residential and commercial HVAC systems. This factory authorized part is engineered to maintain a precise 2.9" WC manifold pressure, ensuring consistent burner ignition and optimal combustion efficiency. Built with a 3/4" NPT inlet/outlet, the valve includes two 1/2" bushings for versatile piping configurations and a stainless steel seat within a brass body for long-term reliability in the field.

As a critical OEM furnace gas valve replacement, the EF34CW246 provides a drop-in solution for a wide range of legacy components. It is the direct replacement for the 36H32-403 and effectively replaces models such as the EF32CB194, EF32CB202, and EF34CW245. The unit features redundant solenoid coils for safety and is compatible with hot surface, direct spark, or proven pilot ignition systems. For technicians handling fuel conversions, this kit includes a gas valve LP conversion kit, allowing for seamless adaptation to liquid propane applications while maintaining precise pressure regulation.

• Versatile Compatibility: Functions as a universal service part for various Carrier, Bryant, and Payne furnaces, replacing the 36H32-403 and numerous EF-series valves.
• Flexible Installation: The 3/4 inch gas valve threading includes 1/2 inch reducers to match existing manifold piping without additional trips to the supply house.
• Multi-Ignition Support: Verified for use with hot surface ignition, direct spark, and intermittent pilot systems, providing broad application coverage.
• Durable Construction: Features a high-grade brass body and stainless steel internal components to resist corrosion and mechanical wear.
• Integrated Regulation: Factory-set for 2.9" WC for natural gas, with an adjustable range of 2.5" to 5.0" to fine-tune manifold pressure.

Common Questions

Is the EF34CW246 compatible with Liquid Propane (LP) systems?
Yes, while the unit is factory-configured for natural gas at 2.9" WC, it includes a gas valve conversion kit to safely adapt the regulator for LP applications, typically ranging from 7.0" to 12.0" WC.

Can I use this valve to replace a 1/2" inlet gas valve?
This 3/4" x 3/4" gas valve comes standard with two 1/2" bushings, making it compatible with systems using either 3/4" or 1/2" NPT piping connections.

What ignition systems does this valve support?
The EF34CW246 is a highly versatile Carrier replacement gas valve designed to work with 24VAC systems using hot surface ignition (HSI), direct spark ignition (DSI), or proven pilot configurations.
