Nordyne 624695R Gas Valve

Professional-grade Nordyne 624695R Gas Valve is a 2-stage gas valve engineered for precision fuel regulation in residential and light commercial furnaces. This OEM replacement gas valve is the direct successor to the Nordyne 624695 and is built for consistent performance in intermittent pilot and Hot Surface Ignition (HSI) systems. Operating on a standard 24V circuit, this valve facilitates tiered heating—low-fire and high-fire stages—to optimize combustion efficiency and temperature stability. For field versatility, it features 3/4" NPT threading and includes reducers for 1/2" applications, along with an LP conversion kit for liquid propane transitions. As a veterans’ choice for furnace gas valve replacement, it manages manifold pressure accurately, ensuring reliable burner ignition and quiet operation. Whether you are servicing an Intertherm, Miller, or Nordyne unit, this valve provides the exact fit and flow rate required to restore factory-spec manifold pressures and safe heating cycles.

• Dual-Stage Modulation: Enhances energy efficiency and shortens warm-up times by switching between low and high heating outputs.
• Direct OEM Compatibility: Specifically designed to replace Nordyne part 624695 and 6241100 without manifold modifications.
• Universal Fuel Options: Ships setup for natural gas but includes the necessary hardware for LP gas conversion in the field.
• Fast-Opening Design: Ensures immediate gas flow for direct spark ignition and hot surface systems, reducing ignition delay.
• Standardized Connections: Features a 3/4" x 3/4" NPT configuration with 1/2" reducers to match common gas lines.

Is the 624695R compatible with 624695?
Yes, the Nordyne 624695R is the official updated replacement for the original 624695 model, sharing identical mounting footprints and electrical requirements.

Does this valve support both natural gas and propane?
The valve is factory-configured for natural gas but includes an LP conversion kit, allowing technicians to adapt the unit for propane applications during installation.

Which ignition systems can use this valve?
This 2-stage replacement valve is compatible with most modern furnace ignition sequences, including hot surface ignition (HSI) and direct spark ignition (DSI) setups.
