8American Dryer Corp.113014-19
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.
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 110 inch2 (710 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.
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.
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.
The dryer shall not be exhausted into any gas vent, chimney ,
wall, ceiling or concealed space of a building.
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.
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. There should be a minimum
6-inch (15.24 cm) clearance between the back guard and
the first bend in the ductwork for ease of servicing. 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, overlap the duct being connected. All ductwork
joints must be taped to prevent moisture and lint from
escaping into the building. This unit is fitted with an integral
backdraft damper (inside the 8” [20.32 cm] exhaust
connection). Inspection doors should be installed at strategic
points in the exhaust ductwork for periodic inspection and
cleaning of lint from the ductwork.
A = 15-inches (38.1 cm)
B = 15-inches (38.1 cm)
EXAMPLE: For a bank of four dryers, two unrestricted openings measuring
15-inches by 15-inches (38.1 cm by 38.1 cm) are acceptable.
IMPORT ANT: 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.
IMPORTANT: Exhaust back pressure measured by a
manometer/magnehelic in the exhaust duct must be no
less than 0 and must not exceed 0.6 in WC (1.5 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 0.6 inch water column.
Where employed, booster fans must not activate the dryer
airflow proving switch (sail switch) when the dryer is not in
operation.
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.”
The ductwork for this appliance must be suitable for the
appliance category in accordance with national installation
regulations of the country of destination.
113014-19www.adclaundry.com9
Outside Ductwork Protection
T o protect the outside end of the horizontal ductwork from
the weather, a 90° elbow bent downward should be inst alled
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.
Single Dryer Venting
IMPORT ANT : For extended ductwork runs, the crosssectional area of the ductwork can only be increased to an
extent. When the ductwork approaches the maximum
limits as noted in this manual, a professional HVAC firm
should be consulted for proper venting information.
Horizontal Venting
When horizontal dryer venting is used, the length of the
ductwork from the dryer to the outside exhaust outlet, must
not exceed 25 feet (7.62 meters). The minimum diameter of
this ductwork must be at least 8-inches (20.32 cm). Including
tumbler/dryer elbow connections or elbows used for outside
protection from the weather, no more than 1 elbow should be
used in the exhaust duct run. If more than 1 elbow is used,
the cross-sectional area of the ductwork must be increased.
A = 25 feet (7.62 meters)
B = 8” (20.32 cm)
C = 25 feet (7.62 meters)
D = 8” (20.32 cm)
Vertical Venting
When vertical dryer venting is used, the length of the ductwork
from the dryer to the outside exhaust outlet, must not exceed
25 feet (7.62 meters). The minimum diameter of this ductwork
must be at least 8-inches (20.32 cm). Including tumbler/dryer
elbow connections or elbows used for outside protection from
the weather, no more than 3 elbows should be used in the
exhaust duct run. If more than 3 elbows are used, the crosssectional area of the ductwork must be increased.
NOTE 1 Opening from combustible materials must be 2-inches (5.08 cm)
larger than the duct (all the way around). The duct must be centered
within this opening.
NOTE 2 Distance should be 2 times the diameter of the duct to the nearest
obstruction.
Multiple Dryer (Common) Venting
IMPORT ANT : For extended ductwork runs, the crosssectional area of the ductwork can only be increased to an
extent. When the ductwork approaches the maximum
limits as noted in this manual, a professional HVAC firm
should be consulted for proper venting information.
If it is not feasible to provide separate exhaust ducts for each
dryer, ducts from individual dryers may be channeled into a
“common main duct.” The individual ducts should enter the
bottom or side of the main duct at an angle not more than
45º in the direction of airflow. The main duct should be
tapered, with the diameter increasing before each individual
duct is added.
IMPORTANT: No more than 4 dryers should be
connected to 1 main common duct.
The illustration on the next page shows the minimum crosssectional area for multiple dryer round or square venting.
These figures must be increased if the main duct run from
the last dryer to where it exhausts to the outdoors is longer
than 20 feet (6.1 meters) or has more than 1 elbow in it.

others will be N.P.T.
Installer within Australia – refer to AS/NZS5601.1 for
guidance on gas supply pipe sizing required for this
appliance installation.
There should be a minimum 6-inch (15.24 cm) clearance
between the back guard and the first bend in the gas piping
for ease of servicing. It is recommended that a gas shutoff
valve be provided to the gas supply line of each dryer for
ease in servicing.
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 L.P. gas, the supply tank, other gasoperated 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.
IMPORTANT: Pipe joint compounds that resist the action
of natural, L.P., and butane gases must be used.
Test all connections for leaks by brushing on a soapy
water solution (liquid detergent works well).

and Cyprus cannot be converted from one family of gas to
another.
Conversion from Natural Gas
to Propane or Butane Gas
The following conversion allows the dryer to be operated
with either propane, butane, or LPG. The use of gas valve
kit (ADC P/N 140414) disables the internal regulator of the
gas valve. Therefore, the gas supply is ungoverned and an
external regulator must be provided at the source of the
supply (example L.P. tank) or the gas supply line to the dryer.
The type of L.P. kit supplied will depend on the country the
dryer is installed in.
* Refer to page 14 for orifice (injector) size.
** Required for unregulated propane or butane only.
*** Required for regulated LPG or propane only.
Instructions
Consistent gas pressure is essential at all gas connections.
It is recommended that a 3/4-inch (19.05 mm) pipe gas loop
be installed in the supply line servicing a bank of dryers. An
in-line pressure regulator must be installed in the gas supply
line (header) if the (natural) gas pressure exceeds 13.0 in
WC (32.34 mb) pressure.
A plugged tap, accessible for a pressure gauge connection,
must be installed in the main gas supply line immediately
upstream of the dryers.

Gas Pressure Adjustment
Disconnect electrical power to the dryer.
IMPORTANT: It is required that the following procedures
be performed on both burner assemblies.
To adjust gas valve’s internal regulator, remove the regulator
vent cap with the regulator adjustment tool, which is located
on the back guard between the gas inlet and exhaust outlet
(refer to the illustration below for proper use of adjustment
tool). Be sure to use one of the wide ends of the adjustment
tool for removal of the vent cap. Once vent cap is removed,
the narrow end of the adjustment tool can be used to turn the
plastic adjustment screw in the valve. Turn the screw
clockwise to raise pressure and counterclockwise to lower
pressure.
Gas (burner) pressures are measured with the burner in
operation for all burner adjustment conditions. Therefore
once the necessary adjustments have been made, the dryer
must be operated in a heating cycle to verify that the pressure
is correct. Refer to “Gas Pressure Testing” on this page. If it
is not correct, you must discontinue the power to the unit
and make further adjustments. Repeat these steps as many
times as necessary to achieve the correct burner pressure.
Once the adjustment of the valve is complete, the vent cap
must be replaced and sealed with, for example, paint to
prevent maladjustment by the user.
WARNING(CE Dryers)
This appliance must only be operated with the gas
type indicated on the dryer’s data plate. If the
appliance is converted (gas type changed), a data
plate amendment must be obtained from American
Dryer Corporation.
Conversions done improperly can result in a fire or
explosion!
Gas Pressure Testing _________________
For proper operation, the gas pressure must be correct,
consistent and maintained at the gas pressure rates shown
on page 14. Provisions are made at the gas valve for taking
gas pressure readings.
There are 2 types of devices used to measure gas pressure.
They are the spring/mechanical type gauge and the
manometer. The use of the spring/mechanical type gauge is
not recommended because they are very easily damaged
and are not always accurate. The preferred type of gauge is
the manometer because it is a simple device to use and is
highly accurate. A manometer is simply a glass or transparent
plastic tube with a scale graduated in inches or millibar. When
it is filled with water and pressure is applied, the water in the
tube rises, showing the exact gas pressure.
Gas Pressure Test Procedure
Turn gas cock in gas supply line to “OFF” position.
50 Hz dryers: Back out miniature screw inside pressure tap
and attach manometer.
60 Hz dryers: Install pressure tap and attach manometer.
Turn gas cock to “ON” position.
Start the dryer in Heat Mode and wait for ignition. Gas
manifold pressure should be as shown on page 14.
Once test is complete, turn gas cock to “OFF” position.
Remove manometer. Tighten screw inside the pressure tap
or install plug.
Turn gas cock to “ON” position and check for leaks with soap
solution with main burner “ON.”
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, state, and
country 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 25 feet (7.6 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.
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 – High Pressure
Shaded areas are stated in metric equivalents
* The minimum operating pressure for optimum results is 100 psig (689.47
kPa).
Installation Instructions
T o 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.
18American Dryer Corp.113014-19
!
!
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 minimum capacity of 214 lb
(97.06 kg) of condensate per hour at 150 psi (1 MPa) is
needed for each unit. (Based on 2 times the steam
consumption per hour.)
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.
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 (0.31 meters)
back towards the steam supply header causing the
condensate in the line to drain to the header. Inst all 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.
Water Connections
The water connection is made to the 3/4”-11.5 NH hose
adaptor, which is shipped in the tumbler and must be inst alled
to the 1/2” N.P.T . water connection, located at the upper rear
of the dryer. A flexible supply line/coupling must be used in
an effort to avoid damaging the electric water solenoid valve.
NOTE: The 3/4”-11.5 NH is a standard hose coupling
screw thread. It is not to be confused with 3/4” N.P.T. The
sealing of an NH connection is made with a washer
opposed to the mating threads of an N.P.T. assembly. The
2 thread designs are not compatible.
It is recommended that a filter or strainer be installed in the
water supply line.
IMPORTANT: Flexible supply line/coupling must be used.
Solenoid valve failure due to hard plumbing connections
will void warranty.
The dryer is to be connected to the water mains using a
new hose set and the old hose set should not be reused.
Electrical Requirements
No independent external power source or supply connection
is necessary. The 24-volt power to operate the fire
suppression system is accomplished internally in the dryer
(from the dryer controls).
Water Information ____________________

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.
Microprocessor Programs / Selections
Each microprocessor controller (computer) has been
preprogrammed by the factory with the most commonly used
parameter (program) selections. If computer program
changes are required, refer to the computer programming
manual, which was shipped with the dryer.
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 Dryers
Open all shutoff valves.
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.
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) must be
verified.
IMPORTANT: In most cases there is no regulator provided
in an L.P. dryer. The water column pressure must be
regulated at the source (L.P. tank), or an external regulator
must be added to each dryer.
Preoperational Instructions __________
IMPORT ANT: For more detailed information regarding the
microprocessor controller (computer), refer to the
microprocessor user’s manual included with the dryer.

Routine Maintenance _________________
Cleaning
A program and/or schedule should be established for
periodic inspection, cleaning, and removal of lint from various
areas of the dryer, as well as throughout the ductwork
system. The frequency of cleaning can best be determined
from experience at each location. Maximum operating
efficiency is dependent upon proper airflow. The
accumulation of lint can restrict this airflow. If the guidelines
in this section are met, the dryer will provide many years of
efficient, trouble free, and most importantly, safe operation.
WARNING
Lint from most fabrics is highly combustible. The
accumulation of lint can create a potential fire hazard.
Keep dryer area clear and free from combustible
materials, gasoline, and other flammable vapors and
liquids.
NOTE: Suggested time intervals shown are for average
usage, which is considered 6 to 8 operational (running)
hours per day.
IMPORTANT: Dryer produces combustible lint and must
be exhausted to the outdoors. Every 6 months, inspect
the exhaust ducting and remove any lint buildup.
Suggested Cleaning Schedule
Every Third or Fourth Load
Clean the lint screen every third or fourth load. A clogged lint
screen will cause poor dryer performance. The lint door/
drawer is located just below the loading door of the dryer.
Open the lint door/drawer, brush the lint off the lint screen,
and remove the lint. Inspect lint screen and replace if torn.
NOTE: To remove the lint drawer from the dryer, pull the
drawer out loosen the torx screws on the sides of the rails.
This allows the metal clips to rotate and allow the drawer
to be fully removed. Reverse the above process for
installation.
IMPORTANT: The frequency of cleaning the lint screen
can best be determined from experience at each location.
Weekly
Clean lint accumulation from lint chamber, thermostat, and
microprocessor temperature sensor area.
WARNING
To avoid the hazard of electrical shock, discontinue
electrical supply to the dryer.
Steam Dryers
Clean the steam coil fins. It is suggested that compressed
air and a vacuum cleaner with brush attachment be used.
WARNING
When cleaning steam coil fins, be careful not to bend
the fins. If fins are bent, straighten by using a fin
comb, which is available from local air-conditioning
supply houses.
90 Days
Remove lint from gas valve burner area with a dusting brush
or vacuum cleaner attachment.
Clean any lint accumulation in and around the motor(s) casing
opening.
NOTE: To prevent damage, avoid cleaning and/or
touching ignitor/flame-probe assembly.
Every 6 Months
Inspect and remove lint accumulation in customer furnished
exhaust ductwork system and from dryer’s internal exhaust
ducting.
NOTE: To remove the lint drawer from the dryer, pull the
drawer out until it stops. There are two T-20 torx screws on
each side of the lint drawer holding down the lint drawer
catch brackets which must be loosened. Once they are
loose the drawer will be able to be pulled completely out
of the machine. To reinstall put the lint drawer back into
the machine, line up the lint drawer catch brackets with
the screws and tighten them down.
The accumulation of lint in the exhaust ductwork can
create a potential fire hazard.
Do not obstruct the flow of combustion and ventilation air.
Check back draft dampers in the exhaust ductwork.
Inspect and remove any lint accumulation, which can
cause the damper to bind or stick.
A back draft damper that is sticking partially closed can
result in slow drying and shutdown of heat circuit safety
switches or thermostats.
If the hi-limit trips due to a high temperature occurrence,
you must disconnect power before resetting. To reset,
press and release the reset button, which is located on the
top front, left corner of the dryer.
When cleaning the dryer cabinet(s), avoid using harsh
abrasives. A product intended for the cleaning of
appliances is recommended.
7 Days After Installation
and Every 12 Months Thereafter
A competent professional should inspect bolts, nuts, screws,
setscrews, grounding connections and nonpermanent gas
connections (unions, shutoff valves, and orifices). Belts
should be examined. Cracked or seriously frayed belts
should be replaced. Complete an operational check of
controls and valves. Complete an operational check of all
safety devices (lint door/drawer switch, door switches, sail
switch, and hi-limit thermostats).
