A common problem with barometric dampers is misadjusted air draft.

A common problem with barometric dampers is indeed misadjusted air draft. Barometric dampers are designed to help regulate airflow in heating systems, particularly those that use chimneys or flues for venting combustion gases. When these dampers are properly adjusted, they allow for the optimal amount of air to enter the system, helping to maintain efficiency and safety.

However, if the dampers are misadjusted, it can lead to insufficient or excessive draft. This can create several issues, including poor combustion efficiency, increased fuel consumption, and potential safety hazards such as the release of harmful gases into the living space. Proper maintenance and regular checks are essential to ensure the dampers are functioning correctly and that the air draft is set according to the specifications for the system in use. This understanding emphasizes the importance of attention to detail in HVAC system setup and maintenance, highlighting why misadjusted air draft is a noteworthy concern with barometric dampers.
