What is a key consideration for installations involving a power exhauster based on safety?

The correct choice emphasizes the importance of the proper connection location when installing a power exhauster. This consideration is crucial because the exhauster must be connected to the system in a way that ensures the safe and efficient removal of air or gas from the building. If the connection is not to an appropriate location, it can lead to improper ventilation, potential backdrafts, or the introduction of hazardous gases into occupied spaces.

Proper connection locations also take into account the flow dynamics of the system, ensuring that the exhaust is directed safely outside, away from windows, doors, or air intakes, which can compromise indoor air quality and safety. Therefore, ensuring that the exhauster is connected correctly is essential for both operational efficiency and the safety of the occupants.

While other considerations, like power supply reliability, proper labeling, and the type of flue material, are important in their own right, they do not hold the same immediate impact on the safe and effective operation of the power exhauster as the connection location does.
