Key Features

• OEM replacement vent damper designed for Utica-Dunkirk heating equipment
• 7″ diameter for precise fit and optimal airflow control
• Automatically closes the flue when the burner cycles off, reducing standby heat loss

Why Use a Vent Damper?

Vent dampers are installed in the flue pipe between the heating appliance and the chimney. When the heating system shuts off between cycles, the damper blade closes automatically, sealing the flue and preventing warm air from escaping the living space up the chimney. This significantly reduces standby losses, helping homeowners and building operators save on fuel costs while maintaining system reliability.
