Barometric dampers must be installed in what location?

Barometric dampers must be installed in the same room as the oil heating unit to ensure proper functioning within the system. This placement allows the damper to effectively manage the airflow from the furnace or boiler, optimizing combustion efficiency and overall system performance. When a barometric damper is correctly located with respect to the heating unit, it can properly respond to the fluctuations in pressure, helping to maintain balanced chimney draft and preventing issues such as backdrafts or excessive draft.

This ensures that the system operates safely and efficiently, ultimately extending the life of the heating equipment and enhancing the comfort of the space being heated. Placing the damper outside or in an attic would hinder its ability to regulate the air flow properly, leading to potential operational issues. Additionally, positioning it in a separate room from the unit would disconnect the damper's function from the system it is intended to serve. Such a configuration could lead to inefficiencies or safety hazards.
