A. 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.
NOTE: For non-coin dryer models equipped with locks, the lock used is a dummy lock and no
key is supplied or needed. The lock can be turned with any key, a screwdriver, a small
coin, or any small sharp object. For coin-operated dryers, the MK-100 (master key for
both the control door and lint door) should be made accessible because it will be needed
throughout various phases in the installation of the dryer.
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 (4) bolts securing the base of the dryer to the wooden skid. Two (2) are at
the rear base (remove the back panel for access), and two (2) are located in the bottom of the lint chamber. To
remove the two (2) 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 (4)
leveling legs, so that the dryer will slide on the legs instead of the base frame.
Leveling Dryer
The dryer is equipped with four (4) leveling legs, one (1) at each corner of the base. Two (2) are located at the
rear of the dryer base, and two (2) are located in the lint chamber (coop). To increase bearing life and improve
efficiency, the dryer should be tilted slightly to the rear.

10 American Dryer Corp. 113235 -17
B. LOCATION REQUIREMENTS
Before installing the dryer, ensure the location conforms to local codes and ordinances. In the absence of such
codes or ordinances the location must conform with National Fuel Gas Code ANSI Z223.1/NFPA 54, or in
Canada, the installation must conform to applicable Canadian Standards: Natural Gas and Propane Installation
Code CSA B149.1.
1. The dryer must be installed on a sound level floor capable of supporting its weight. Carpeting must be

7. The dryer must be installed with a proper exhaust duct connection to the outside as noted in this manual
(refer to Exhaust Requirements in Section E).
8. The dryer must be located in an area where correct exhaust venting can be achieved as noted in this
manual (refer to Exhaust Requirements in Section E).
IMPORTANT: The dryer should be located where a minimum amount of exhaust duct will be
necessary.
9. 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 build up.
IMPORTANT: The dryer must be installed in a location/environment, which the ambient
temperatureremainsbetween 40° F(4.44° C)and130°F(54.44° C).

113235- 17 www.adclaundry.com 11
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; except along the front of the dryer, which may be closed if
desired.
NOTE: Allowances must be made for opening the control door.
X = 12-inch (30.48 cm) minimum, 24-inches (60.96 cm) is suggested for ease of maintenance.
NOTE: Airconsiderations areimportantfor properandefficientoperation.
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 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 above for details.

12 American Dryer Corp. 113235 -17
D. FRESH AIR SUPPLYREQUIREMENTS
This appliance may only be installed in a room that meets the appropriate ventilation requirements specified in the
nationalinstallation regulations.
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 72 inch2(464.51 cm2) is required for each dryer. (Based on 1 inch2[6.5 cm2] 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.
EXAMPLE: For a bank of 8 dryers, 2 unrestricted openings measuring 16-inches by 18-inches (40.64 cm by
45.72 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
exitthe 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-upairmust be free of dry cleaning solvent fumes. Make-up air thatis
contaminatedbydrycleaningsolventfumes willresult inirreparabledamagetothe
motorsandother dryer components.
NOTE: Componentfailureduetodrycleaningsolventfumeswillvoid thewarranty.

113235- 17 www.adclaundry.com 13
E. EXHAUST REQUIREMENTS
Exhaust ductwork shouldbedesigned 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.
The design of the flue system shall be such that any condensate formed when operating the appliance from cold
shall either be retained and subsequently re-evaporated or discharged.
CAUTION: Thisdryerproducescombustible lint and mustbeexhaustedtotheoutdoors.
When possible, it is suggested to provide a separate (single) exhaust duct for each dryer.
CAUTION: IMPROPERLY SIZED ORINSTALLEDEXHAUSTDUCTWORKCAN
CREATEAPOTENTIALFIREHAZARD.
IMPORTANT: Exhaustback pressuremeasuredby amanometer/magnehelicin theexhaustduct
must be no less than 0 and must not exceed 0.3 in WC (0.74 mb).
NOTE: Itisrecommendedthatexhaustorboosterfansnotbeusedintheexhaust ductwork system
exceptwherenecessary to maintainexhaustbackpressure(in the exhaustduct)betweenzero
and0.3inch water column. Whereemployed,boosterfans must notactivatethedryerairflow
provingswitch(sail switch)whenthedryer isnotinoperation.
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: Whenconnectingductworktothe dryer exhaust duct, be sure that whenscrewsare
usedtheyDONOTrestricttheoperation(both opening and closing) of the damper.
NOTE: Whentheexhaust ductworkpassesthrough awall,ceiling,or roofmadeof combustible
materials,theopeningmustbe2 inches(5.08cm)largerthan the duct (allthewayaround).
Theductmustbecenteredwithin thisopening.
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).

14 American Dryer Corp. 113235 -17
IMPORTANT: DONOTusescreens,louvers, or caps on the outside opening of the exhaust
ductwork.
NOTE: AspertheNationalFuelGasCode,“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.”
SINGLE DRYER VENTING
IMPORTANT: Forexhaustduct runs over 40feet(12meters)a minimum size of10-inches(25.4cm)
must be used.
HORIZONTAL VENTING OF MODEL ADG-285DH (With Heat Reclaimer)
When horizontal single 8-inch (20.32 cm) venting is used with modelADG-285DH, the ductwork to the outlet
cannot exceed 40 feet (12 meters) refer to Illus.Abelow. This calculation of 40 feet (12 meters) compensates
