Field Controls 46579100 Wiring Harness Kit

The Field Controls 46579100 Wiring Harness Kit is the essential universal wiring harness required for the proper integration and synchronization of GVD Series Vent Dampers with modern gas-fired appliances. As a direct 46390008 cross reference, this 8-foot kit provides the necessary low voltage connections to ensure the damper cycles correctly with the burner. The harness features a keyed plug design, a critical safeguard that prevents polarity errors or incorrect wiring during field installation. By utilizing the dual safety switches integrated into the damper motor, this harness ensures the burner circuit remains open unless the damper blade is in the fully open position, protecting against flue gas spillage. Contractors typically use this Field Controls GVD-UWK kit to replace damaged OEM leads or when extending the run between the damper and the 24V control transformer. The stainless steel construction of the damper components, paired with this robust harness, maintains system integrity by preventing heat loss through the flue during off-cycles.

Key Technical Benefits:

• Direct Compatibility: Engineered specifically for Field Controls GVD vent dampers, ensuring seamless 24V communication.
• Enhanced Safety Logic: Facilitates the interlock between the damper and burner to guarantee 100% natural draft before ignition.
• Universal Length: The 8-foot wiring harness provides ample slack for flexible mounting configurations on vertical or horizontal flues.
• Error-Proof Installation: Keyed connectors eliminate guesswork, reducing diagnostic time and potential board shorts.
• Draft Protection: Supports the normally closed operation of the GVD-UWK, preventing cold air infiltration and conditioned air loss.

Common Questions:

Can I use this 46579100 harness on other damper brands?
This kit is designed specifically for Field Controls GVD and OVD series dampers. Using it with non-compatible brands may bypass safety interlocks and is not recommended for code compliance.

What is the difference between the 46579100 and the 46390008?
The Field Controls 46579100 is the current replacement part number for the older 46390008, offering identical fit and function for modern vent damper motors.

How do the safety switches work with this harness?
The harness completes the circuit to the gas valve only after the internal limit switches confirm the damper has reached a 90-degree open position.
