For make-up air, an opening must have an area of not less than how many square inches when a closet is designed for a dryer?

• A. 80 sq inches
• B. 100 sq inches
• C. 120 sq inches
• D. 150 sq inches

Answer: (B)

The requirement for make-up air openings for a closet designed for a dryer is essential for ensuring proper ventilation and preventing the buildup of heat or harmful gases. The specified minimum area of 100 square inches helps facilitate adequate airflow for the dryer to operate efficiently. This airflow is crucial, as it supports optimal combustion and drying processes, maintaining the safety and performance of the appliance. In practice, the 100 square inches standard is derived from guidelines that aim to balance the air exchange effectively. Adequate make-up air allows the dryer to exhaust air without creating negative pressure, which can lead to hazardous situations. Therefore, this requirement ensures that the appliance can draw enough fresh air when it is in operation. Those values might vary in different contexts or jurisdictions, but the specific regulation in this case emphasizes the importance of sufficient make-up air for safety and functionality.
