Reznor 221526 Gas Valve

The Reznor 221526 Gas Valve is a direct OEM replacement for 36H32-442, engineered for high-performance natural gas applications in Reznor gas-fired unit heaters and industrial HVAC equipment. This 24V gas valve features a redundant solenoid design to provide reliable gas flow control and safe combustion cycles. It is factory-set for a 3.5" WC (Water Column) outlet pressure, ensuring consistent manifold pressure for Natural Gas systems, though it includes a standard regulator for precision field adjustments by qualified technicians.

Built with robust 3/4" x 3/4" NPT inlet and outlet connections, this combination gas valve supports significant heating capacities and is a versatile fit for most electronic ignition systems including HSI, DSI, and intermittent pilot configurations. The Reznor 221526 is designed for demanding environments, maintaining stable operation in ambient temperatures from -40°F to 175°F. When troubleshooting intermittent heating or ignition lockouts, contractors often look to this 36H series valve to resolve issues related to faulty coils or inconsistent manifold pressure.

Key Benefits

• Universal Compatibility: Serves as a direct replacement for 36H32-442 and various Reznor heater parts, streamlining inventory for service calls.
• Precise Pressure Regulation: Features an adjustable 3.5" WC regulator to maintain optimal Natural Gas flow for efficient burner performance.
• Redundant Safety Design: Incorporates dual internal solenoid valves to provide an extra layer of protection during gas shutoff.
• Heavy-Duty Ports: Equipped with 3/4" NPT connections and inlet/outlet screens to prevent debris from fouling internal valve seats.

Common Questions

• Can this valve be field-converted for LP gas? While the 221526 is factory-calibrated for Natural Gas, many 36H series valves can be converted using a specific White-Rodgers LP conversion kit. Check the manufacturer's manifold pressure requirements for your specific Reznor model.
• Does this valve support pilot ignition? Yes, this fast-opening gas valve is designed for use with electronic ignition systems, including proven intermittent pilot and direct spark applications.
• How do I test the internal coil? HVAC technicians typically check for 24V at the terminals during the ignition trial. If voltage is present but no gas reaches the manifold, a resistance check across the coil terminals can confirm if the 24V gas valve has failed.
