What is the minimum required makeup opening size if the electric dryer is located in a closet?

The minimum required makeup opening size for an electric dryer located in a closet is set at 100 square inches to ensure proper ventilation. Adequate airflow is essential for the efficient operation of the dryer, preventing overheating and allowing it to function effectively.

Electrical dryers need adequate air circulation for the exhaust system to work properly. Insufficient air supply can lead to longer drying times, increased energy consumption, and potential damage to the appliance. The 100 square inch requirement is based on industry standards that specify sufficient venting to accommodate the needs of the dryer and ensure a safe operation, particularly when installed in a confined space such as a closet.

Larger opening sizes may also be specified for gas dryers or in specific installation conditions to ensure proper ventilation and safety.
