Utica-Dunkirk 240006940 Damper

Utica-Dunkirk 240006940 Damper

Upgrade your system’s efficiency with the Utica-Dunkirk 240006940 Damper, a 8 inch automatic vent damper engineered for precision airflow control in hydronic heating applications. Built with heavy-duty galvanized steel, this OEM replacement part is specifically designed for compatibility with Utica MGB Boiler Series and Dunkirk DXL Series units. The automatic actuator ensures the flue remains closed during the off-cycle to prevent standby heat loss, significantly improving the overall Annual Fuel Utilization Efficiency (AFUE) of the boiler. This UL listed component features a high-torque motor and an integrated proving switch that prevents burner ignition unless the damper is in the fully open position. Designed for vertical or horizontal flue installation, the 240006940 boiler part provides a reliable mechanical seal to resist harsh combustion environments and reduce energy waste. For contractors looking to restore factory-spec timing and safety, this authentic Utica-Dunkirk HVAC part eliminates the reliability issues typically associated with generic universal alternatives.

Key Benefits
  • Enhanced Fuel Efficiency: Minimizes standby heat loss by sealing the vent when the burners are not firing.
  • Robust Construction: Manufactured from corrosion-resistant galvanized steel to withstand high-temperature flue gases.
  • Plug-and-Play Integration: Features a dedicated wiring harness connector for seamless attachment to the boiler control system.
  • Critical Safety Proving: Integrated end-switch ensures the damper plate is completely open before allowing gas valve energization.
  • OEM Precision: Guaranteed fit for Utica and Dunkirk boilers, ensuring consistent draft performance.
Common Questions

Is the Utica-Dunkirk 240006940 compatible with other boiler brands?
This is an OEM replacement part designed specifically for the Utica MGB and Dunkirk DXL series. While it may match the diameter of other systems, use is restricted to specified models to ensure proper safety circuit integration.

What are the signs of a failing automatic vent damper?
Common indicators include the boiler failing to fire despite a call for heat, or the damper remaining in the closed position while the motor is energized. This often suggests a failed drive motor or a faulty proving switch.

Can this 8" damper be installed in any orientation?
Installation must follow the manufacturer’s instructions, typically allowing for vertical or horizontal placement, provided the actuator motor remains accessible for service and the position indicator is visible.
