Which of the following statements is true regarding the installation of exhaust systems?

The statement that proper make-up air supply is necessary is true regarding the installation of exhaust systems. In any exhaust system, especially those in industrial or commercial settings, it is critical to maintain an adequate balance of air within the space. When air is exhausted from a building, an equivalent amount of make-up air needs to be introduced to prevent negative pressure, which can lead to insufficient airflow, impaired combustion processes, and even the backdraft of harmful gases. This balance is vital for both safety and efficiency in heating, ventilation, and air conditioning (HVAC) systems.

Ensure that the make-up air is provided in a manner that does not disrupt the intended operation of the exhaust system. Moreover, the sources of make-up air should be free from contaminants and should be appropriately filtered and conditioned as needed to maintain indoor air quality.

This critical aspect emphasizes the importance of having a properly designed exhaust system in conjunction with a well-planned make-up air supply to ensure safe and efficient operation.
