10 American Dryer Corp. 113362- 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-limit, or lint chamber hi-limit
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: 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.
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.
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.”
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. As a general
rule, an unrestricted air entrance from the outdoors
(atmosphere) of a minimum of 2-1/2 feet2(0.2322576 meters2)
is required for each dryer. (Based on 1 inch2[6.4516 cm2]
per 1,000 Btu [251.9958 kcal].)
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.
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 2 feet by 2-1/2 feet (0.61 meters by 0.762 meters)
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.

Single Dryer Venting
IMPORTANT: For extended ductwork runs, the cross-
sectional 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 20 feet (6.096 meters). The minimum diameter
of this ductwork must be at least 16-inches (40.64 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.
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 below).
IMPORTANT: Do not use screens, louvers, or caps on the
outside opening of the exhaust ductwork.
Vertical Venting
When vertical dryer venting is used, the length of the ductwork
from the dryer to the outside exhaust outlet, must not exceed
20 feet (6.096 meters). The minimum diameter of this
ductwork must be at least 18-inches (45.72 cm) even though
the dryer exhaust duct connection is only 16-inches (40.64
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 cross-sectional area of the ductwork
must be increased.

Multiple Dryer (Common) Venting
IMPORTANT: For extended ductwork runs, the cross-
sectional 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

The dryer is provided with a 1” N.P.T. inlet pipe connection
located at the upper right rear of the dryer. The minimum
pipe size (supply line) to the dryer is 1-inch 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.

Water Information ____________________
Before You Start
Check Local Codes and Permits
Call your local water company or the proper municipal
authority for information regarding local codes.
IMPORTANT: It is your responsibility to have all plumbing
connections made by a qualified professional to ensure
that the plumbing installation is adequate and conforms to
local, state, and federal regulations or codes.
It is the installer’s or owner’s responsibility to see that the
required water pressure, pipe size, or connections are
provided. The manufacturer assumes no responsibility if
the fire suppression system is not connected, installed, or
maintained properly.
Installation
Water Supply
The fire suppression system must be supplied with a minimum
water pipe size of 1/2-inch (12.7 mm) and be provided with
40 psi +/- 20 psi (2.75 bar +/- 1.37 bar) of pressure. For use
of optional manual bypass, a second source with the same
piping and pressure requirements is required.
If the rear area of the dryer or the water supply is located in
an area where it will be exposed to cold/freezing
temperatures, provisions must be made to protect these water
lines from freezing.
!WARNING
If the water in the supply line or water solenoid valve
freezes, the fire suppression system will be
inoperative!!
Water Connections
The water connection is made to the 3/4”-11.5 NH hose
adaptor, located in the upper right 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.
Consistent gas pressure is essential at all gas connections.
It is recommended that a 1-inch (2.54 cm) 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 12.0 in
WC (29.9 mb) pressure.
NOTE: A water column test pressure of 3.5 in WC (8.7 mb)
for natural gas and 10.5 in WC (26.1 mb) for propane
dryers is required at the gas valve pressure tap of each
dryer for proper and safe operation.
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.
IMPORTANT: Pipe joint compounds that resist the action
of natural gas and propane gas must be used.
Test all connections for leaks by brushing on a soapy
water solution (liquid detergent works well).
!WARNING
Never test for leaks with a flame!!!

16 American Dryer Corp. 113362- 25
Optional Manual Bypass
Provisions are made in the dryer’s fire suppression system
for the installation of an optional manual bypass. Depending
on the model dryer, the connections for the manual bypass
are made at the “T” or “three way” fitting, located in the outlet
supply side of the water solenoid valve. The manual ball
cock shutoff valve must be located outside of the dryer at a
distance from the dryer where it is easily accessible. The
use and connections of this manual bypass are at the option
or discretion of the owner.
The water connection for the manual bypass is made to the
“T” or “three way” fitting, which has a 3/8” F.P.T. and a coupling
must be used to provide the minimum 1/2-inch (12.7 mm)
supply (feed) line.
If the rear area of the dryer or the water supply is located in
an area where it will be exposed to cold/freezing
temperatures, provisions must be made to protect these water
lines from freezing.
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 from the
dryer controls.
!WARNING
Electrical power must be provided to the dryer at all
times. If the main electrical power supply to the dryer
is disconnected, the fire suppression system is
inoperative!!

113362-25 www.adclaundry.com 17
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.
Gas dryers are equipped with a DSI system, which has
internal diagnostics. If ignition is not established within 3
attempts, the heat circuit in the DSI module will “lockout”
until it is manually reset. To reset the DSI 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.
Safety Related Circuits
Make a complete operational check of all safety related
circuits:
• Door Switch(es)
• Hi-Limit Thermostats
• Sail Switch
Sail Switch Adjustment
To check for proper sail switch operation (for gas and electric
models only), open the main door and while holding main
door switch plunger in, start dryer. Dryer should start but
heat circuit should not be activated (on). If the heat system
is activated, the sail switch is improperly adjusted and must
be adjusted by bending the actuator arm of the sail switch
toward the burner box. If the actuator arm is bent too far
toward the burner box of the dryer, the dryer may not have
heat when needed. After any adjustment to the sail switch,
the above procedure must be repeated to verify proper
operation of the sail switch.
The dryer should be operated through 1 complete cycle to
ensure that no further adjustments are necessary and that
all components are functioning properly.
Make a complete operational check of all operating controls.
For microprocessor model check controller (computer)
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.
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.
!WARNING
ELECTRICAL SHOCK HAZARD
Electrical shock hazard can result in serious injury.
If the water dispensing system is activated do not
attempt to operate the dryer.
If the water dispensing system is activated have the
dryer inspected by a qualified agency before operating
the dryer.
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 data label. In the case of 208
VAC or 240 VAC, the supply voltage must match the
electric service exactly.
• GAS MODELS – Check to ensure that the dryer is
connected to the type of gas indicated on the data label.
• GAS MODELS – Be sure that all gas shutoff valves are
in the open position.
• 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. (Refer to Sail
Switch Adjustment in the Preoperational Test section.)
• Be sure all back panels (guards) and electric box
covers are in place.
• Be sure the service doors are closed and securely in
place.
• Be sure the lint door/drawer is securely in place.
• Rotate the tumbler (drum) by hand to be sure it moves
freely.
• Check bolts, nuts, screws, terminals, and fittings for
tightness and security.
• Check tumbler bearing setscrews to ensure they are all
tight.
• Check that the 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 Dryers
Open all shutoff valves.

18 American Dryer Corp. 113362- 25
Preoperational Instructions __________
IMPORTANT: For more detailed information regarding the
microprocessor controller (computer), refer to the
microprocessor user’s manual included with the dryer.
Microprocessor Controller (Computer)
The L.E.D. display reads “READY” (no cycle in progress).
Press the letter on the keypad corresponding to the cycle
desired (i.e., key “D”).
The dryer will then start (i.e., blower, tumbler, and heat).
The L.E.D. display will read MANUAL DRYING CYCLE D,
00:00 MIN REMAIN.
NOTE: The dryer can be stopped at any time by pressing
the “STOP/CLEAR” key, at this time the dryer will go into a
cycle pause. If the “STOP/CLEAR” key is pressed again at
this point, the cycle that was in progress will be cancelled
and returned to the “READY” state.
When the programmed drying time has expired, the Phase 7
non-coin microprocessor controller (computer) will proceed
into the Cool Down Cycle.
Once the Cool Down Cycle begins at the end of the heat
cycle, the L.E.D. display will read COOL DOWN TEMP
___/___ MINUTES remaining. At the end of the heat cycle,
the dryer will shut off the heat and continue the fan and
tumbler until the Cool Down Time or temperature is reached.
Shutdown Instructions _______________
If the dryer is to be shutdown (taken out of service) for a
period of time, the following must be performed:
Discontinue power to the dryer either at the external
disconnect switch or the circuit breaker.
Discontinue the heat supply:
Gas Models – Discontinue the gas supply.
SHUT OFF external gas supply shutoff valve.
SHUT OFF internal gas supply shutoff valve located in the
gas valve burner area.
3-Phase (3ø) Electric Service
Check the electric service phase sequence (3-phase [3ø]
models only). While the dryer is operating, check to see if
the blower/fan is rotating in the proper direction. Looking
from the front, the blower/fan should spin in the clockwise
direction, if it is, the phasing is correct. If the phasing is
incorrect, reverse 2 of the 3 leads at connections L1, L2, and
L3 of the power supply to the dryer.
IMPORTANT: If the blower/fan is rotating in the wrong
direction, it will drastically reduce drying efficiency and it
can also cause premature component failure.
Spin and Dwell (Stop) Times Adjustment
Reversing tumbler dryers should never be operated with less
than a 63 lb (28.57 kg) load (dry weight), since the load’s
weight affects tumbler coast time during a direction reversal
command. It is important that the tumbler comes to a
complete stop prior to starting in opposite direction.
Microprocessor Models
Spin and dwell (stop) times are adjustable in the Manual
(Timed) Mode. Spin and dwell (stop) times are not adjustable
in the Automatic Mode and have been preprogrammed into
the microprocessor controller (computer) for 150-seconds
spin time in forward direction, 120-seconds in the reverse
direction and a 5-second dwell (stop) time.
Mechanical Timer Models
Timer models have an electronic reversing timer in the
electrical service box, which is located in the upper right front
area of the dryer.
Both the dwell (stop) time and the tumbler spin time are
adjustable by mode selection switches, located on the
electronic timer (as noted in the illustration below).

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.
Weekly
Clean lint accumulation from lint chamber, thermostat, and
microprocessor temperature sensor (sensor bracket) area.
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.
!WARNING
To avoid the hazard of electrical shock, discontinue
electrical supply to the dryer.
90 Days
Remove lint from around the tumbler, fan blades, and
surrounding areas.
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: 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, right corner of the dryer.
When cleaning the dryer cabinet(s), avoid using harsh
abrasives. A product intended for the cleaning of
appliances is recommended.
Adjustments
7 Days After Installation
and Every 6 Months Thereafter
Inspect bolts, nuts, screws, setscrews, grounding connections
and nonpermanent gas connections (unions, shutoff valves,
and orifices). Motor and drive belts should be examined.
Cracked or seriously frayed belts should be replaced. Tighten
loose V-belts when necessary. Complete operational check
of controls and valves. Complete operational check of all
safety devices (lint door/drawer switch, door switches, sail
switch, and hi-limit thermostats).
Lubrication
The motor bearings, idler bearings, and under normal/most
conditions the tumbler bearings are permanently lubricated.
It is physically possible to relubricate the tumbler bearings if
you choose to do so even though this practice is not
necessary. Use Shell Alvania #2 grease or its equivalent.
The tumbler bearings used in the dryer do not have a grease
fitting. Provisions are made in the bearing housing for the
addition of a grease fitting, which can be obtained elsewhere
or from the manufacturer.
