made for the opening and closing of the control door, along with the removal of panels during maintenance.
D. FRESH AIR SUPPLY REQUIREMENTS
When the dryer is operating, it draws in room air, heats it, passes this air through the basket (tumbler), and
exhausts it out of the building. Therefore, the room air must be continually replenished from the outdoors. If the
make-up air is inadequate, drying time and drying efficiency will be adversely affected. Ignition problems and
sail switch “fluttering” problems may result, as well as premature motor failure from overheating.
Air supply (make-up air) must be given careful consideration to ensure proper performance of each dryer. An
unrestricted source of air is necessary for each dryer. An airflow of 1,700 cfm (cubic feet per minute) (48.14
cmm [cubic meters per minute]) must be supplied to each dryer. As a general rule, an unrestricted air entrance
from the outdoors (atmosphere) of a minimum of 2-1/2 square feet (0.23 square meters) is required for each
dryer. The dryer must be installed with provisions for adequate combustion and make-up air supply.
