American Dryer Corp.
113159-2
C. DRYER ENCLOSURE REQUIREMENTS
Bulkheads and partitions should be made of noncombustible material.
NOTE: Allowances must be made for opening the control door.
A 30-inches (76.2 cm) for optimum opening of load door.
B The maximum thickness of the bulkhead is 4-inches (10.16 cm). For electric dryers the maximum thickness
of the bulkhead is 1-inch (2.54 cm) within 3-inches (7.62 cm) from the top of the control door.
C For gas and electric dryers a minimum overhead clearance of 12-inches (30.48 cm) is required, providing no
sprinkler is located above the dryer. For steam dryers or if a sprinkler is located above the dryer, 18-inches
(45.72 cm) is required
D Dryer should be positioned 12-inches (30.48 cm) away from the nearest obstruction and 24-inches
(60.96 cm) is recommended for ease of installation, maintenance, and service.
E 2-inch (5.08 cm) minimum is required for opening the control door.
F Flooring should be level or below dryer cabinet for ease of removing panels during maintenance.
G Dryers may be positioned sidewall to sidewall, however a 1/16” (1.5875 mm) minimum allowance must be
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.
