Field Controls 46487201 Damper

The Field Controls 46487201 (Model GVD-7PL) is a 7-inch automatic gas vent damper engineered for professionals looking to enhance the efficiency of 24Vac gas-fired boilers and furnaces. This stainless steel unit acts as a direct replacement for Q35RG-1, ensuring a precise fit without the need for extensive field modifications. By sealing off the vent during off-cycles, the GVD-7PL prevents residual heat from escaping up the chimney and blocks cold air infiltration, significantly reducing standby energy losses. It features a dual safety switch system that prevents the burner from firing unless the 7-inch vent damper is confirmed in the fully open position, maintaining the integrity of the existing appliance limit controls. Designed for versatility, it is compatible with both intermittent ignition and standing pilot systems. Please note that this specific SKU is provided without harness; use a keyed wiring harness for a secure, one-way connection. The motorized damper operates with power-open and power-close functionality, completing its 90-degree rotation in approximately 15 seconds to ensure seamless HVAC flue venting performance.

• Direct Replacement: Specifically designed as an exact match for the Q35RG-1, streamlining the swap-out process for service contractors.
• Thermal Retention: Eliminates the "chimney effect" by closing the vent during standby, keeping conditioned air inside the building.
• Superior Durability: Constructed from high-grade stainless steel to resist corrosion and withstand the harsh environment of flue gases.
• Integrated Safety: Redundant internal switches ensure the damper is fully open before allowing the gas valve to energize.
• Service Mode: Includes a manual "hold open" switch to bypass the motor during troubleshooting or seasonal maintenance.

• Is the wiring harness included with this model? No, the Field Controls 46487201 is the damper and motor assembly only. A damper wiring harness must be sourced separately if the existing one is damaged.
• Will this work with a standing pilot furnace? Yes, the GVD-7PL is designed to operate with both 24Vac intermittent ignition and standing pilot ignition systems.
• What is the typical opening time? The unit utilizes a synchronized motor that fully opens or closes the 7" gas vent damper in roughly 15 seconds.
