Where should a draft hood or barometric draft regulator be installed?

The correct placement of a draft hood or barometric draft regulator is in the same room as the appliance they are associated with. This allows for effective regulation of air flow and proper drafting of combustion gases, ensuring that the appliance operates safely and efficiently. Installing the draft hood in the same room allows for immediate response to any changes in pressure, which can affect the performance of the appliance.

Positioning it in the same area helps maintain consistent air pressure and prevents backdrafts or flue gas leakage that could occur if it were installed elsewhere. This location also makes it easier for service personnel to access and inspect the draft hood or regulator, ensuring it functions properly.

Options that suggest placing the draft hood in the basement, in a different room, or outside the building can create issues related to airflow and the safe expulsion of combustion gases. For example, placing it outside could lead to challenges in maintaining the necessary draft and could expose the system to weather-related issues. Therefore, situating the draft hood or barometric draft regulator in the same room as the appliance is best practice for safety and functionality.
