DRYER ENCLOSURE REQUIREMENTS
Bulkheads and partitions should be made of noncombustible
materials and must be located a minimum of
12-inches (30.48 cm) above the dryer’s outer top; 18-inches
(45.72 cm) for steam dryers, except along the front of the
dryer which may be closed if desired.
X = 12-inch (30.48 cm) minimum, 24-inches (60.96 cm) is
suggested for ease of maintenance.
* 1-inch (2.54 cm) maximum for electric dryers.
** 18-inch (45.72 cm) minimum for steam dryers.
EXHAUST REQUIREMENTS
Exhaust ductwork should be designed and installed by a
qualified professional. Improperly sized ductwork will create
excessive back pressure which results in slow drying,
increased use of energy, and shutdown of the burner by the
airflow (sail) switch, burner hi-limit, or lint chamber hi-heat
protector thermostat. The dryer must be installed with a
proper exhaust duct connection to the outside.
NOTE:
Air considerations are important for proper and
efficient operation.
Allowances must be made for opening the
control door.
Dryers may be positioned sidewall to sidewall. However, a
1/16” (1.587 mm) minimum allowance must be made for the
opening and closing of the control door and the lint door. It is
suggested that the dryer be positioned about 2 feet (0.61
meters) away from the nearest obstruction for ease of
installation, maintenance, and service (to be measured from
the back guard). Refer to the illustration below for details.
FRESH AIR SUPPLY REQUIREMENTS
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. As a general rule,
an unrestricted air entrance from the outdoors (atmosphere)
of a minimum of 1 square foot (0.09 square meters) is required
for each dryer. If registers or louvers are installed over the
openings, then the area must be increased. It is not
necessary to have separate make-up air openings for each
dryer. Common make-up air openings are acceptable.
However, they must be set up in such a manner that the
make-up air is distributed equally to the dryers. The dryer
must be installed with provisions for adequate combustion
and make-up air supply.
EXAMPLE: For a bank of eight (8) dryers, two (2)
unrestricted openings measuring 2
feet x 2 feet (0.61 meters x 0.61 meters)
are acceptable.
IMPORTANT:
Make-up air openings should not be located
in an area directly near where exhaust vents
exit the building.
Allowances must be made for remote or constricting
passageways or where dryers are located at excessive
altitudes or predominantly low pressure areas.
IMPORTANT:
Make-up air must be provided from a source
free of dry cleaning solvent fumes. Make-up air
that is contaminated by dry cleaning solvent
fumes will result in irreparable damage to the
motors and other dryer components.
NOTE:
Component failure due to dry cleaning solvent
fumes will VOID THE WARRANTY.
