Field Controls GVD-5PL Automatic Vent Damper for Gas Systems - 5-Inch 24V

The Field Controls GVD-5PL is a 5-inch automatic vent damper designed for use with 24-volt gas heating systems. This energy-saving device automatically closes the vent pipe when the heating system is not operating, preventing heated or cooled air from escaping up the chimney and reducing standby heat loss.

Key Features:

• 5-inch diameter fits standard vent pipe applications
• Compatible with 24-volt gas heating systems including furnaces and boilers
• Automatic operation—opens during heating cycle and closes when system shuts off
• Reduces energy waste by preventing conditioned air loss through the vent
• Heavy-duty construction for reliable, long-term performance
• Wiring harness sold separately (not included with this unit)

This vent damper helps improve heating system efficiency by minimizing heat loss during non-operation periods. Professional installation is recommended to ensure proper operation and compliance with local building codes. Field Controls part number 464 provides the same functionality as this GVD-5PL model.
