supporting its weight. Carpeting must be removed from the
floor area that the dryer is to rest on.
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.
Provisions for adequate air supply must be provided as noted
in this manual (refer to Fresh Air Supply Requirements
section).
Clearance provisions must be made from combustible
construction as noted in this manual (refer to Dryer Enclosure
Requirements section).
Provisions must be made for adequate clearances for
servicing and for operation as noted in this manual
(refer to Dryer Enclosure Requirements section).
The dryer must be installed with a proper exhaust duct
connection to the outside as noted in this manual (refer to
Exhaust Requirements section).
The dryer must be located in an area where correct exhaust
venting can be achieved as noted in this manual (refer to
Exhaust Requirements section).
The dryer can be moved to its final location while still attached
to the skid or with the skid removed. To remove the skid from
the dryer, locate and remove the 4 bolts securing the base of
the dryer to the wooden skid. 2 are at the rear base (remove
the back panel for access) and 2 are located in the bottom of
the lint chamber. (Remove the lint drawer/door for access.)
With the skid removed, to make it easier to slide the dryer
into its final position, slightly lower all 4 leveling legs, so
that the dryer will slide on the legs instead of the base frame.
Leveling Dryer
The dryer is equipped with 4 leveling legs, 1 at each corner of
the base. 2 are located at the rear of the dryer base, and 2
are located in the lint chamber. To increase bearing life and
improve efficiency, the dryer should be tilted slightly to the
rear.
Dr yer Enclosure Requirements ______

material.
Note
Allowances must be made for opening the
!
control door.
Important
The dryer should be located where a minimum
!
amount of exhaust ducting will be necessary.
The dryer must be installed with adequate clearance for air
openings into the combustion chamber.
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.
113610-1 www.amdry.com 7
A 30-inches (76.2 cm) for optimum opening of load door.
B The maximum thickness of the bulkhead is 4-inches (10.16 cm). For
electric 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.
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. As a general
rule, an unrestricted air entrance from the outdoors
(atmosphere) of a minimum of 150
required for each dryer. (Based on 12 inch per 1,000 Btu.)
A = 17-inches (43.18 cm)
B = 18-inches (45.72 cm)
2
inches (967.742 cm) is
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.
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 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. Single or independent dryer venting
is recommended. It is suggested that the use of 90° turns
be avoided; use 30° and/or 45° bends instead. The radius of
the elbows should preferably be 1-1/2 times the diameter of
the duct. All ductwork should be smooth inside with no
projections from sheet metal screws or other obstructions,
which will collect lint. When adding ducts, the duct to be
added should overlap the duct to which it is to be connected.
All ductwork joints must be taped to prevent moisture and lint
from escaping into the building. Inspection doors should be
installed at strategic points in the exhaust ductwork for
periodic inspection and cleaning of lint from the ductwork.
To compensate for the use of registers or louvers used over
the openings, this area must be increased by approximately
thirty-three percent. Make-up air openings should not be
located in an area directly near where exhaust vents exit the
building.
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 4 dryers, 2 unrestricted openings
measuring 17-inches by 18-inches (43.18 cm by 45.72 cm)
are acceptable.
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
It is recommended that exhaust or booster fans
!
not be used in the exhaust ductwork system.
Exhaust back pressure measured by a manometer/
magnehelic in the exhaust duct must be no less than 0
and must not exceed 0.3 in WC (0.74 mb).
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.
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-inches [0.50 mm]) thick.”
Outside Ductwork Protection
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 (refer
to the diagram).
Important
Do not use screens, louvers, or caps on the
!
outside opening of the exhaust ductwork.
