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, 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.
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: “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.

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” (1.59 mm) minimum allowance must be made for
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 above for details.
Dryer must be exhausted to the outdoors as noted in this
manual (refer to Exhaust Requirements).
Dryer must be located in an area where correct exhaust
venting can be achieved as noted in this manual (refer to
Exhaust Requirements).
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.
With the exception of the floor, clearances shown are for
combustible construction.

8 American Dryer Corp. 113229-25
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.
When possible, it is suggested to provide a separate (single)
exhaust duct for each dryer.
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: This dryer produces combustible lint and
must be exhausted to the outdoors.
Improperly sized or installed exhaust ductwork can
create a potential fire hazard.
IMPORTANT: 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: It is recommended that exhaust or booster fans
not be used in the exhaust ductwork system except where
necessary to maintain exhaust back pressure (in the
exhaust duct) between zero and 0.3 inch water column.
Where employed, booster fans must not activate the dryer
airflow proving switch (sail switch) when the dryer is not in
operation.
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: 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.
Fresh Air Supply Requirements ______
This appliance may only be installed in a room that meets
the appropriate ventilation requirements specified in the
national installation regulations.
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. As
a general rule, an unrestricted air entrance from the outdoors
(atmosphere) of a minimum of 1-1/2 square feet (0.14
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 separate
make-up air openings 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 3 feet by 2 feet (0.914 meters by 0.61
meters) are acceptable.
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.

113229 -25 www.adclaundry.com 9
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/
magnehelic in the exhaust duct must be no less than 0
and must not exceed 0.3 in WC (0.74 mb).
NOTE: It is recommended that exhaust or booster fans
not be used in the exhaust ductwork system except where
necessary to maintain exhaust back pressure (in the
exhaust duct) between zero and 0.3 in WC. Where
employed, booster fans must not activate the dryer airflow
proving switch (sail switch) when the dryer is not in
operation.
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 gauges
(0.0195-inches [0.50 mm]) thick.”
Single Dryer Venting
Horizontal Venting
When a single 8-inch (20.32 cm) horizontal vent is used,
the ductwork to the outlet cannot exceed 68 feet (20.7
meters), refer to Illus. A below. This calculation of 68 feet
(20.7 meters) compensates or allows for the use of a
maximum of only one elbow, (which is the outside outlet
protection).
Illus. A
Vertical Venting
When vertical single 8-inch (20.32 cm) venting is used (refer
to Illus. B below), the ductwork from the dryer to the outside
outlet cannot exceed 55 feet (16.7 meters). This calculation
compensates for the use of a maximum of three elbows
including the two elbows creating the 180° (turned
downward) outside outlet.
Illus. B
If the length of the duct run or quantity of elbows used
exceeds the above noted specifications, the cross-sectional
area of the ductwork must be increased in proportion to the
number of elbows or duct run added.
IMPORTANT: For extended ductwork runs, the cross
section area of the duct can only be increased to an
extent. For extended ductwork runs, a professional HVAC
firm should be consulted for proper venting information.
Multiple Dryer (Common) Venting
If it is not feasible to provide separate exhaust ducts for
each dryer, ducts for individual dryers may be channeled
into a common main duct. Each dryer is provided with a
back draft damper. The individual ducts should enter the
bottom or side of the main duct at an angle not more than
45° in the direction of the airflow.
The main common duct may be any shape as long as the
minimum cross-sectional area is provided. The main duct
should be tapered with the diameter increasing before each
individual 8-inch (20.32 cm) duct is added (refer to Illus. C
for horizontal venting and Illus. D for vertical venting on the
following page).
IMPORTANT: No more than four dryers maximum should
be connected to one main common duct with a vertical
run.
NOTE: Distance between dryer single ducts being
connected to the main common duct must be a minimum
of 34-1/4” (87 cm) dryer width.
Ductwork should be laid out in such a manner where
allowances are made at rear area of the dryer for removal
of rear service panels or guards.

10 American Dryer Corp. 113229-25
The illustrations below show the minimum cross section area for
multiple dryer venting. These figures must be increased in
proportion if the main duct run from the last dryer to where it
exhausts has numerous elbows or is unusually long.
IMPORTANT: For extended ductwork runs, the cross section
area of the duct can only be increased to an extent. For
extended ductwork runs, a professional HVAC firm should be
consulted for proper venting information.
Refer below for Multiple Dryer Horizontal Venting and Vertical
Venting examples/illustrations.

pressure must be regulated upstream of the dryer. The
pressure measured at each gas valve pressure tap must
be a consistent 10.5 in WC (26.1 mb). There is no regulator
or regulation provided in a propane dryer. The pressure
must be regulated at the source (propane tank) or an external
regulator must be added to each dryer.
Steam Information ___________________
It is your responsibility to have all plumbing connections
made by a qualified professional to ensure that the steam
plumbing installation is adequate and conforms with local
and state regulations or codes.
Care must be exercised when leveling steam dryers into
final position. After leveling the dryer, check the downward
pitch of the heat exchanger from front to rear with a level.
Likewise, check the downward pitch of the return condensate
manifold toward its outlet part. Absence of these downward
pitches will result in probable water hammer and premature
heat exchanger fracture and leakage.
The presence of condensate in the steam will cause water
hammer and subsequent heat exchanger failure. The steam
supply connection must be taken from the top of a
well-dripped steam main. If the supply run-out to the dryer
exceeds 20 feet (6.1 meters), it should be dripped just before
the control valve with a proper trap and dirt pocket.
IMPORTANT: Failure to comply with the requirements
stipulated in this manual can result in component failure,
which will void the warranty.
NOTE: This dryer is manufactured with a pneumatic
(piston) damper system, which requires an external
supply of air (80 psi +/- 10 psi [5.51 bar +/- 0.68 bar]).

General Installation and Gas Plumbing), as well as local
codes and ordinances and must be done by a qualified
professional. It is important that gas pressure regulators
meet applicable pressure requirements, and that gas meters
be rated for the total amount of all the appliance Btu being
supplied.
Installer within Australia – refer to AS/NZS5601.1 for
guidance on gas supply pipe sizing required for this
appliance installation.
The dryer is provided with a 1/2” N.P.T. inlet pipe connection
extending out the back area of the burner box. The minimum
pipe size (supply line) to the dryer is 1/2” diameter. For
ease in servicing, the gas supply line of each dryer must
have its own shutoff valve.
The size of the main gas supply line (header) will vary
depending on the distance this line travels from the gas
meter or, in the case of propane gas, the supply tank, other
gas-operated appliances on the same line, etc. Specific
information regarding supply line size should be determined
by the gas supplier.
NOTE: Undersized gas supply piping can create a low or
inconsistent pressure, which will result in erratic operation
of the burner ignition system.
A plugged tap 1/8” N.P.T. minimum, accessible for a
pressure gauge connection, must be installed in the main
gas supply line immediately upstream of the dryers.

16 American Dryer Corp. 113229-25
Water pockets in the supply line, caused by low points, will
provide wet steam to the coil possibly causing steam coil
damage. All horizontal runs of steam supply piping should
be pitched 1/4-inch (6.35 mm) for every 1 foot (0.30 meters)
back towards the steam supply header causing the
condensate in the line to drain to the header. Install a bypass
trap in any low point to eliminate wet steam.
IMPORTANT: Flexible hoses/couplings must be used.
Coil failure due to hard plumbing connections will void the
warranty.
Steam Damper Air System Connections
This dryer is manufactured with a pneumatic (piston) damper
system, which requires an external supply of compressed
air. The air connection is made to the steam damper
solenoid valve, which is located at the rear inner top area of
the dryer just in front of the electric service relay box.
Compressed Air Supply Air Pressure
Normal 80 psi 5.51 bar
Minimum Supply 70 psi 4.82 bar
Maximum Supply 90 psi 6.21 bar
Air Requirements
There is no air requirement for dryers with the
electromechanical steam damper option.
Shaded areas are stated in metric equivalents
Air Connection
Air connection to system — 1/8” N.P.T.
Air Regulation
No air regulator or filtration is provided with the dryer. External
regulation/filtration of 80 psi (5.51 bar) must be provided. It
is suggested that a regulator/filter gauge arrangement be
added to the compressed air line just before the dryer
connection. This is necessary to ensure that correct and
clean air pressure is achieved.
Steam Coil pH Level
The normal pH level for copper type steam coils must be
maintained between a value of 8.5 to 9.5. For steel type
steam coils the pH level must be maintained between a
value of 9.5 to 10.5. These limits are set to limit the acid
attack of the steam coils.
IMPORTANT: Coil failure due to improper pH level will
void the warranty.
Steam Requirements
Shaded areas are stated in metric equivalents
* The minimum operating pressure for optimum results is 100 psig (689.47
kPa).
Installation Instructions
To ensure an adequate supply of steam is provided, be
sure that the steam supply line and steam return line are
sized and laid out as stipulated in this manual. Inadequate
steam supply line and steam return line or improper steam
plumbing will result in poor performance and can cause
component failure. Clean, dry steam must be provided to
the dryer.
IMPORTANT: Steam coil failure due to water hammer by
wet steam will void the warranty.
The presence of condensate in the steam supply line will
cause water hammer and subsequent heat exchanger
(steam coil) failure. The steam supply connection into the
main supply line must be made with a minimum 10-inch
(25.4 cm) riser. This will prevent any condensate from
draining towards the dryer.
The steam supply line to the dryer must include a 12-inch
(30.48 cm) riser along with a drip trap and check valve. This
will prevent any condensate from entering the steam coil.
Flexible hoses or couplings must be used. The dryer
vibrates slightly when it runs and this will cause the steam
coil connections to crack if they are hard piped to the supply
and return mains.
Shutoff valves for each dryer should be installed in the
supply line, return line, and drip trap return line. This will
allow the dryer to be isolated from the supply main and the
return main if the dryer needs maintenance work.
Install an inverted bucket steam trap and check valve at
least 12-inches (30.48 cm) below the steam coil as close
to the coil as possible. A trap with a capacity of 350 lb (160
kg) of condensate per hour at 125 psi (8.61 bar) is needed
for each unit.
The supply line and the return line should be insulated.
This will save energy and provide for the safety of the operator
and maintenance personnel.

Steam Damper System Operation
The steam damper, as shown in the illustration below,
allows the coil to stay constantly charged eliminating
repeated expansion and contraction. When the damper is
opened, the air immediately passes through the already
hot coil, providing instant heat to start the drying process.
When the damper is closed, ambient air is drawn directly
into the tumbler, allowing a rapid cool down.
Diagram 1 shows the damper in the heating (open) mode,
allowing heat into the tumbler.
Diagram 2 shows the damper in the cool down (closed)
mode, pulling ambient air directly into the tumbler without
passing through the coils.
NOTE: With the dryer off or with no air supply, the steam
damper is in cool down mode as shown in Diagram 2.
Steam Damper Air Piston (Flow Control)
Operation Adjustment
Damper operation was tested and adjusted prior to shipping
at 80 psi (5.51 bar). If damper air adjustment is necessary,
locate the flow control valve and make the necessary
adjustments as noted below.

Gas model dryers are equipped with an ignition system,
which has internal diagnostics. If ignition is not established
after one time, the heat circuit in the ignition module will
attempt two more ignitions (total of three ignition attempts).
If there is no flame after the third ignition attempt the module
will lock out until it is manually reset. To reset the ignition
system, open and close the main door and restart the dryer.
A gas pressure test should be taken at the gas valve
pressure tap of each dryer to ensure that the water column
pressure is correct and consistent.
NOTE: Water column pressure requirements (measured
at the pressure tap of the gas valve body):
Natural Gas .............. 3.5 in WC (8.7 mb)
Propane Gas ............ 10.5 in WC (26.1 mb)
IMPORTANT: There is no regulator provided in a propane
dryer. The water column pressure must be regulated at
the source (propane tank), or an external regulator must
be added to each dryer.
Make a complete operational check of all safety related
circuits:
• Door Switch(es)
• Hi-Limit Thermostats
• Cycling Thermostat
• Gas and Electric Models Only – Sail Switch
NOTE: The sail switch can be checked for proper
operation by opening the lint drawer. While pushing the
lint drawer switch in, start a drying cycle. The heating unit
should not activate (wait 30-seconds). If heat does
activate, make the necessary adjustments to the sail
switch.
Make a complete operational check of all operating controls.
NOTE: If computer program changes are required, refer to
the computer programming section of the manual
supplied with the dryer.
The dryer should be operated through one complete cycle
to ensure that no further adjustments are necessary and
that all components are functioning properly.
Tumbler Coating
The tumbler is treated with a protective coating. We suggest
dampening old garments or cloth material with a solution
of water and nonflammable mild detergent and tumbling
them in the tumbler to remove this coating.
Check the electric service phase sequence (3-phase [3ø]
models only). While the dryer is operating, check to see if
the blower wheel (impellor/fan) is rotating in the proper
direction. Looking from the front, the blower wheel (impellor/
fan) should spin in the clockwise direction. If it is, the phasing
is correct. If the phasing is incorrect, reverse two of the
three leads at connections L1, L2, and L3 of the power supply
to the dryer.
IMPORTANT: If the blower wheel (impellor/fan) is rotating
in the wrong direction, it will drastically reduce drying
efficiency and it can also cause premature component
failure.
Preparation For Operation / Start-Up_
The following items should be checked before attempting
to operate the dryer:
• Read all “Caution”, “Warning”, and “Direction” labels
attached to the dryer.
• Check incoming supply voltage to be sure that it is the
same as indicated on the dryer data label.
• Gas Models – check to ensure that the dryer is
connected to the type of heat/gas indicated on the dryer
data label.
• Gas and Electric Models – the sail switch damper
assembly was installed and adjusted at the factory prior
to shipping. However, each sail switch adjustment
must be checked to ensure that this important safety
control is functioning.
• Check bolts, nuts, screws, terminals, and fittings for
tightness and security.
• Gas Models – be sure that all gas shutoff valves are in
the open position.
• Check that all back guard panels and service box
covers have been replaced.
• Check the lint drawer to ensure that it is closed and
secured in place.
• Rotate the tumbler (drum) by hand to be sure it moves
freely.
• Steam Models – check to ensure that a clean, dry,
regulated air supply (80 psi [5.51 bar]) is on the dryer
(with air-operated damper system only).
• Steam Models – check to ensure all steam shutoff
valves are open.
• Steam Models – check steam damper operation.
• Check tumbler bearing setscrews to ensure that they
are all tight.
• Check vent is connected to the dryer and is exhausted
to the outdoors.
Preoperational Test __________________
All dryers are thoroughly tested and inspected before leaving
the factory. However, a preoperational test should be
performed before the dryer is publicly used. It is possible
that adjustments have changed in transit or due to marginal
location (installation) conditions. Installer must instruct the
user on how to correctly operate the dryer before leaving.
Turn on electric power to the dryer.
Refer to the Operating Instructions for starting your particular
model dryer.
Gas Models Only
When a gas dryer is first started (during initial start-up), it
has a tendency not to ignite on the first ignition attempt.
This is because the gas supply piping is filled with air, so it
may take a few minutes for the air to be purged from the
lines.
NOTE: During the purging period, check to be sure that all
gas shutoff valves are open.
