Which issue is commonly associated with barometric dampers?

Barometric dampers are devices that help regulate the airflow in a ventilation system by opening and closing based on pressure changes. One common issue associated with these dampers is spillage, which occurs when flue gases do not properly exit through the chimney or venting system. This can lead to dangerous situations, as spillage can release harmful gases into the living space, posing health risks to occupants.

When a barometric damper is functioning correctly, it equalizes pressure in the system and ensures that combustion gases are effectively vented outside. However, if the damper is not set to the appropriate pressure levels or if it becomes obstructed, it can fail to close properly, allowing exhaust gases to spill back into the home. This highlights the critical role barometric dampers play in maintaining not only the efficiency of heating systems but also the safety of indoor air quality.

Understanding the risks associated with spillage emphasizes the importance of proper installation and maintenance of barometric dampers to safeguard against potentially hazardous situations.
