Modine 5H0797510000 Gas Valve

The Modine 5H0797510000 Gas Valve is the direct engineering update for the legacy 5H79751, designed specifically for high-efficiency unit heater applications. As a veteran-grade single-stage gas valve, this component is technically identical to 36G22-501, providing a seamless field 1:1 replacement for White-Rodgers equipped systems. Engineered for natural gas service, it operates on a standard 24V AC control circuit with a 0.28A current draw, regulating outlet pressure to a precise 3.5" WC. The 1/2" NPT inlet and outlet allow for straightforward manifold mounting in Modine Hot Dawg and HDS/HDC series heaters. This redundant solenoid valve is optimized for direct spark ignition (DSI) and hot surface ignition (HSI) systems, supporting a maximum inlet pressure of 0.5 PSI. Built to withstand demanding mechanical room environments, it maintains a wide operating range from -40°F to 175°F, ensuring reliable gas flow regulation and consistent burner performance during heavy heating cycles.

Key Benefits

• Universal Modern Replacement: Directly replaces the discontinued 5H79751 and matches the 36G22-501 footprint for zero-modification installs.
• Precision Pressure Regulation: Factory-set to 3.5" WC Nat with a ±0.1" WC accuracy to prevent over-firing and ensure optimal combustion.
• Multi-Poise Mounting: The combination control design allows for flexible mounting orientations in tight heater cabinets.
• Industrial Durability: Features an ambient temperature rating up to 175°F, ideal for high-heat HVACR environments.
• Enhanced Safety: Redundant solenoid design provides secondary shut-off protection for critical heating systems.

Common Questions

Can this valve be converted for Propane (LP) use?
Yes, while this is a natural gas valve, it is compatible with White-Rodgers F92-0659 conversion kits to achieve the required 10.0" WC for LP applications.

Will this work with my Modine Hot Dawg heater?
This OEM-spec valve is the standard replacement for most Modine HD and HDS units manufactured after May 2007 utilizing spark ignition.

What is the proper inlet pressure for this unit?
The maximum allowable inlet pressure is 0.5 PSI (approx. 14" WC). Exceeding this can damage the internal diaphragm and solenoid assembly.
