Dryer must be located in an area where correct exhaust venting
can be achieved as noted in this manual (refer to Exhaust
Requirements).

Unpacking/Setting Up _________________

Remove protective shipping material (i.e., plastic wrap and
optional shipping box) from dryer.

Important

Dryer must be transported and handled in an

!

upright position at all times.

The dryer can be moved to its final location while still attached
to the skid or with the skid removed. To unskid the dryer,
locate and remove the four bolts securing the base of the
dryer to the wooden skid. Two are at the rear base (remove
the back panel for access), and two are located in the bottom
of the lint chamber. To remove the two bolts located in the lint
chamber area, remove the lint door.

With the skid removed, to make it easier to slide the dryer
into its final position, slightly lower all four leveling legs, so
that the dryer will slide on the legs instead of the base frame.

Leveling Dryer

The dryer is equipped with four leveling legs, one at each
corner of the base. Two are located at the rear of the dryer
base, and two are located in the lint chamber (coop). To
increase bearing life and improve efficiency, the dryer should
be tilted slightly to the rear.

Location Requirements _______________

Before installing the dryer, be sure the location conforms to
local codes and ordinances. In the absence of such codes or
ordinances the location must conform with the National Fuel
Gas Code ANSI.Z223.1 LATEST EDITION, or in Canada, the
installation must conform to applicable Canadian Standards:
CAN/CGA-B149.1-M91 (Natural Gas) or CAN/CGA-B149.2­M91 (L.P. Gas) or LATEST EDITION (for General Installation
and Gas Plumbing).

The dryer must be installed on a sound level floor capable of
supporting its weight. Carpeting must be removed from the
floor area that the dryer is to rest on.

Important

Dryer should be located where a minimum amount

!

of exhaust duct will be necessary.

The dryer must be installed with a proper exhaust duct
connection to the outside.

The dryer must be installed with provisions for adequate
combustion and make-up air supply.

Caution

This dryer produces combustible lint and must be

!

exhausted to the outdoors. Every 6 months,

inspect the exhaust ducting and remove any lint buildup.

Important

Dryer must be installed in a location/environment,

!

which the ambient temperature remains between

40º F (4.44º C) and 130º F (54.44º C).

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.

Note

Allowances must be made for opening the control

!

door.

Important

“The dryer must be installed on noncombustible

!

floors only.”

The dryer must not be installed or stored in an area where it
will be exposed to water and/or weather.

The dryer is for use in noncombustible locations.

8 American Dryer Corp. 113237- 4

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.

Note

Air considerations are important for proper and

!

efficient operation.

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. 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 on the previous page for details.

Fresh Air Supply Requirements _______

The 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 460 cfm (cubic feet per minute) (13 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 1 square foot (0.093 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 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 the dryers. The dryer
must be installed with provisions for adequate combustion
and make-up air supply.

EXAMPLE: For a bank of eight dryers, two unrestricted
openings measuring 2 feet by 2 feet (0.61 meters by 0.61
meters) (4 square feet [0.372 square meters]) are acceptable.

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.

When possible, it is suggested to provide a separate (single)
exhaust duct for each dryer.

Caution

This dryer produces combustible lint and must be

!

exhausted to the outdoors.

Improperly sized or installed exhaust ductwork can create a
potential fire hazard.

The exhaust ductwork should be laid out in such a way that
the ductwork travels as directly as possible to the outdoors
with as few turns as possible. The shape of the ductwork is
not critical as long as the minimum cross section area is
provided. Single or independent dryer venting is
recommended.

It is suggested that the use of 90° turns be avoided; use 30°
or 45° angles instead.

The ductwork should be smooth inside with no projections
from sheet metal screws or other obstructions, which will
collect lint. When adding ducts, the ducts to be added should
overlap the duct to which it is connected. All ductwork joints
must be taped to prevent moisture and lint from escaping into
the building. Additionally, inspection doors should be installed
at strategic points in the exhaust ductwork for periodic
inspection and cleaning.

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.

Important

When connecting ductwork to the dryer exhaust

!

duct, be sure that when screws are used they do
not restrict the operation (both opening and closing) of the
damper.

Note

When the exhaust ductwork passes through a wall,

!

ceiling, or roof made of combustible materials, the
opening must be 2-inches (5.08 cm) larger than the duct (all
the way around). The duct must be centered within this
opening.

To protect the outside end of the horizontal ductwork from the
weather, a 90° elbow bent downward should be installed where
the exhaust exits the building. If the ductwork travels vertically
up through the roof, it should be protected from the weather
by using a 180° turn to point the opening downward. In either
case, allow at least twice the diameter of the duct between
the duct opening and the nearest obstruction (i.e., roof or
ground level).

Important

Do not use screens, louvers, or caps on the

!

outside opening of the exhaust ductwork.

Exhaust back pressure measured by a manometer at the
dryer exhaust duct area must be no less than 0 and must
not exceed 0.3 in WC (0.74 mb).

It is recommended that exhaust or booster fans not be used
in the exhaust ductwork system.
