The Nordyne 624775 Gas Valve is a 24V natural gas furnace valve engineered for precision regulation in Nordyne, Miller, and Intertherm heating systems. As a direct OEM replacement gas valve, it replaces obsolete part numbers 624657R and Honeywell VR8215S1289. This single-stage, standard opening valve is factory-set to a 3.5" WC manifold pressure, ensuring optimal combustion efficiency and stable burner flame characteristics. Featuring a 1/2" NPT inlet and 3/4" NPT outlet, it provides the necessary flow capacity for residential gas furnaces while maintaining a compact footprint for easy installation in tight furnace vestibules.

Key Benefits for Contractors:

• Direct Fit Compatibility: Seamlessly replaces Honeywell VR8215S1289 without the need for manifold modifications.
• Reliable Ignition: Engineered for 24V control circuits, delivering consistent solenoid actuation for safe burner cycles.
• Technical Precision: Pre-calibrated for natural gas applications at 3.5 inches water column for out-of-the-box performance.
• Built to OEM Specs: Professional-grade construction ensures the mechanical integrity of the furnace gas control system.

Common Technical Questions:

Is the Nordyne 624775 compatible with LP (Propane) systems?
This valve is factory-configured for natural gas. For Liquid Propane conversions, a specific LP conversion kit must be installed per the manufacturer's instructions to ensure safe manifold pressure.

Can I use this to replace a VR8215S1289?
Yes, the 624775 is the direct service replacement for the VR8215S1289 and 624657R, maintaining the same electrical and physical specifications.

What are the connection sizes?
This 1/2" x 3/4" gas valve features a 1/2" NPT inlet and a 3/4" NPT outlet to meet the high-demand requirements of Nordyne furnace manifolds.
