What is a common operational issue faced by barometric dampers?

A common operational issue faced by barometric dampers is misadjusted air draft. Barometric dampers are designed to help regulate the air pressure within a flue system, ensuring that the exhaust gases are vented properly while allowing for the right amount of outside air to enter. If these dampers are misadjusted, they may not open or close correctly, leading to improper air drafts within the system. This can result in inefficient operation of the heating appliance, increased fuel consumption, or even backdrafting where combustion gases enter the living space rather than being vented outside.

Addressing the adjustment of the air draft is crucial for optimizing appliance performance, maintaining safety, and ensuring proper ventilation. Regular maintenance and checks are essential to keep the barometric damper functioning correctly, and any misalignments should be corrected for the system to work effectively.
