Field Controls 46487001 Vent Damper

The Field Controls 46487001 Vent Damper (Model GVD-5PL) is a critical component for optimizing gas-fired heating systems. As a 5-inch automatic vent damper, it is engineered to mitigate standby heat loss by sealing the flue when the burner is off. This 24VAC 60Hz unit features a robust stainless steel construction, ensuring long-term reliability in residential and light commercial applications. It serves as a direct replacement for Honeywell D896A1194, Q35RC-1, and previous GVD-5 models. By regulating exhaust flow, this energy-saving damper maintains internal heat during off-cycles, effectively increasing the overall efficiency of the appliance while preventing flue gas spillage.

Key Benefits for Contractors

• Broad Compatibility: Functions as a seamless retrofit vent damper for various 24V gas furnace and boiler configurations.
• Optimized Efficiency: Significantly reduces standby losses and fuel consumption by controlling ventilation exhaust.
• Industrial-Grade Build: High-grade stainless steel damper blade and housing resist corrosion and heat fatigue.
• Simplified Service: Designed for integration with the FC-6 wiring harness (sold separately) using dual Molex connectors for fast plug-and-play installation.
• Proven Performance: Provides a mechanical interlock to ensure the burner only fires when the damper is in a fully open position, ensuring safe combustion gas venting.

Common Questions

Is this damper compatible with my current Honeywell setup?
Yes, the 46487001 is the designated replacement for Honeywell D896A1194. It uses a 24VAC control circuit and is compatible with systems requiring a 5-inch flue diameter.

Does the GVD-5PL include the wiring harness?
No, this model is the damper unit only. If your installation requires a new harness, you must procure the FC-6 wiring harness separately. It is designed for plug-in applications using Molex connectors.

Can I install this on an oil-fired system?
No, the Field Controls GVD series is specifically engineered for gas-fired heating equipment. For oil applications, a different series of dampers must be utilized to meet specific code and temperature requirements.
