Dryer Enclosure Requirements __
Bulkheads and partitions should be made of
noncombustible material.
A. The requirement to allow the dryer door to open completely
is 331/2" (85.1 cm).
B. A minimum overhead clearance of 12" (30.48 cm) is
required.
C. Dryer should be positioned a minimum of 12" (30.48 cm)
away from the nearest obstruction. 24" (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" (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 in
2
(1,445 cm
2
) is required for each dryer.
(Based on 1 in
2
[6.5 cm
2
] per 1000 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.
EXAMPLE: For a bank of four dryers, two unrestricted
openings measuring 20" by 221/2" (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.
As per the National Fuel Gas Code, “Exhaust ducts for
type 2 clothes dryers shall be constructed of sheet metal or
other noncombustible material. Such ducts shall be equivalent
in strength and corrosion resistance to ducts made of
galvanized sheet steel not less than 26 gauge
(0.0195" [0.50 mm]) thick.”
