Nordyne Intertherm 624434 Robertshaw Gas Valve Natural Gas Lp Convertible Pilot Light Replaces 624583 624583R

Product Description

The NORDYNE INTERTHERM 624434 is a Robertshaw 7200ERCS-1 gas valve designed for use in many Nordyne, Miller, and Intertherm furnaces equipped with a pilot light ignition system. This valve controls the flow of gas to the burner assembly, regulating pressure and ensuring safe, reliable ignition during each heating cycle. HVAC technicians working on Nordyne-brand furnaces will find this a direct replacement for a wide range of original equipment valves, making it a practical choice for service calls and scheduled maintenance alike. The valve ships preset for natural gas operation, so it is ready to install on most residential and light commercial systems without any additional adjustment. The gas line inlet measures 1 half inch and is positioned on the left side of the valve body. The outlet measures 3 eighths of an inch and exits from the back of the valve. These port dimensions are important to verify against the existing piping before installation. Conversion to propane or LP gas is straightforward. Remove the cap marked NAT, flip it over so the LP side faces outward, and reinstall it. This field conversion requires no special tools and can be completed in minutes. When converting fuel types, technicians must also swap the burner orifices to match the new fuel. Failure to change orifices can result in improper combustion, unsafe operation, or equipment damage. This valve carries internal part reference 7C7-H8F-545. It replaces several legacy part numbers commonly found in Nordyne service records, including 624370, 624466, 624491, 6244913, 624581, 624583, 624583B, 624583C, 624609, and 624621. Because furnace gas valves vary in appearance across production runs, the replacement unit may not look identical to the original. Physical differences do not affect function or compatibility. Always verify the replacement part number against the furnace model and service manual before installation.
