EXAMPLE: For a bank of 4 dryers, 2 unrestricted openings
measuring 20-inches by 22.5-inches (50.80 cm by 57.15 cm)
are acceptable.
To compensate for the use of registers or louvers used over
the openings, this area must be increased by approximately
33%. 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 high altitudes
or predominantly low pressure areas.
IMPORTANT: Make-up air must be 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.
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-limits, or lint chamber hi-limit
protector thermostat. The dryer must be installed with a proper
exhaust duct connection to the outside.
A = 20-inches (50.80 cm)
B = 22.5-inches (57.15 cm)
Dryer Enclosure Requirements _______
A The requirement to allow the dryer door to open
completely is 33.5-inches (85.1 cm).
B A minimum overhead clearance of 12-inches (30.48 cm)
is required.
C Dryer should be positioned a minimum of 12-inches
(30.48 cm) away from the nearest obstruction. 24-inches
(60.96 cm) is recommended for ease of installation,
maintenance, and service.
D 1/16” (1.5875 mm) minimum is required.
E Flooring should be level or below dryer cabinet for ease
of removing panels during maintenance.
F 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.
G 4-inch (10.16 cm) maximum.
Fresh Air Supply Requirements _______
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. Fresh air
ventilation openings shall not be blocked and/or sealed. As
a general rule, an unrestricted air entrance from the outdoors
of 224 inch
2
(1,445 cm
2
) is required for each dryer. (Based on
1 inch
2
[6.5 cm
2
] per 1,000 Btu [252 kcal].)
It is not necessary to have a separate make-up air opening
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 all the dryers.
Fire Hazard
Use a heavy metal vent.
Do not use a plastic vent.
Do not use a metal foil vent.
Failure to follow these instructions can result in
death or fire.
