Field Controls 46487601 GVD-12PL 12-Inch Automatic Gas Vent Damper

The Field Controls GVD-12PL (Part # 46487601) is a high-performance, stainless steel automatic vent damper designed for 24 VAC gas systems. This gas venting damper works automatically to allow natural draft during appliance operation while preventing residual appliance heat and conditioned air from escaping during off cycles. It also prevents the infiltration of cold air during down drafts.

Key Features:

• Stainless steel construction provides superior corrosion resistance
• Dual safety switches allow the burner to fire only when the damper is in the open position
• Operates with all 24 VAC 60Hz intermittent ignition and standing pilot ignition systems
• Opening and closing takes approximately 15 seconds
• Damper can be locked in the open position for service and troubleshooting
• 12-inch diameter for larger vent pipe applications
• Made in the USA

How It Works:

The gas venting damper is installed in the vent pipe, after the draft hood, or draft control. During off cycles, it remains in the closed position, preventing air flow through the vent. When there is a call for heat the motor is energized rotating the damper 90° to an open position. When the damper is fully open the burner is allowed to fire and flue gases pass freely through the vent. When the thermostat is satisfied the burner stops and the damper automatically closes.

Note: This unit is sold without the wiring harness. We recommend that this appliance only be installed by a licensed professional to ensure safety and performance.
