C. DRYER ENCLOSURE REQUIREMENTS
Bulkheads and partitions should be made of noncombustible material.
NOTE: Allowances must be made for opening the control door.
A 38-inches (76.2 cm) for optimum opening of load door.
B The maximum thickness of the bulkhead for gas dryers is 4-inches (10.16 cm). For electric and steam 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
This appliance may only be installed in a room that meets the appropriate ventilation requirements specified in the
national installation regulations.
When the dryer is operating, it draws in room air, heats it, passes this air through the 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. The dryer must be
installed with provisions for adequate combustion and make-up air supply.
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 2,800 cfm (79.28 cmm) must be supplied to
each dryer. As a general rule, an unrestricted air entrance from the outdoors (atmosphere) of a minimum of 3
square feet (0.279 square meters) is required for each dryer.
To compensate for the use of registers or louvers used over the openings, this make-up air must be increased by
approximately thirty-three percent (33%). Make-up air openings should not be located in an area directly near
where exhaust vents exit the building.
