Reznor 222037 Gas Valve

The Reznor 222037 is a mission-critical 24V replacement gas valve designed for precision fuel regulation in natural gas-fired HVAC systems. Engineered for high-demand industrial and commercial unit heaters, this 3/4" NPT gas valve features a preset 3.5" WC output pressure to ensure optimal manifold performance and clean combustion. As an authentic OEM Reznor part, it provides a direct-fit solution for maintaining factory-standard safety and efficiency, eliminating the risks associated with generic alternatives during a service call. The rugged valve body is constructed to withstand the cycling stresses typical of duct furnaces and large-scale heating equipment. When diagnosing ignition failures or erratic flame signals, this Honeywell or White-Rodgers crossover component (often referenced by part number 96309) provides the reliable gas flow control necessary to bring your customer’s system back online efficiently. Ensure your unit heater serial number matches the Reznor HVAC replacement parts catalog for seamless electrical and mechanical integration.

Key Benefits:

• Precise 3.5" Water Column Regulation: Maintains consistent natural gas flow for stable burner operation and maximized heating efficiency.
• OEM-Grade Reliability: Built to Nortek Global HVAC specifications for heavy-duty commercial environments, ensuring long-term field performance.
• Standard 24V Configuration: Simplifies troubleshooting and replacement within existing unit heater control circuits and ignition modules.
• Dual 3/4" NPT Connections: Features robust inlet and outlet threading for secure, leak-proof installations in high-capacity furnaces.

Common Questions:

• What units is the Reznor 222037 compatible with? It is commonly utilized in larger-capacity Reznor duct furnaces and unit heaters; always verify your specific model and serial number to confirm 3/4" gas valve compatibility.
• Can this valve be field-converted to Liquid Propane (LP)? This specific iteration is calibrated for 3.5" WC Natural Gas. For LP applications, a designated conversion kit or an LP-specific model must be used to ensure safe manifold pressure.
• Does this include the ignition pilot assembly? This part number is for the gas valve kit only. If your electrodes or pilot burners are fouled, they should be inspected and ordered separately during the repair.
