material.
NOTE: Allowances must be made for opening the control
door.

113279-9www.adclaundry.com 9
Domestic Type I
EXAMPLE: Two unrestricted openings measuring 6-inches
by 10-inches (15.24 cm by 25.4 cm) are acceptable.
If a closet door is installed: unobstructed air openings are
required. The air openings shall be located 3-inches
(7.62cm) fromthe loweropening(above floorlevel) andupper
opening(below ceiling). Thetotalfree areaof theairopenings
in the door shall not be less than 130 inch2(838.708 cm2).
Louvered doors with equivalent air openings are acceptable.
No other fuel-burning appliance shall be installed in the same
closet as the dryer.
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 timeand dryingefficiency willbe adversely
affected. Ignition 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 26 inch2(168 cm2) 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.
EXAMPLE: For a bank of four dryers, two unrestricted
openingsmeasuring 10-inchesby 6-inches(25.4 cmby 15.24
cm) are acceptable.
IMPORTANT: 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.
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
burnerhi-limitsor blowerhousing hi-limitprotector 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
thatthe useof 90°turns beavoided; use30° and/or45° 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. Back draft dampers must be installed in all
commonly ducted systems. Inspection doors should be
installed at strategic points in the exhaust ductwork for
periodic inspection and cleaning of lint from the ductwork.
A = 6-inches (15.24 cm) B = 10-inches (25.4 cm)
A = 10-inches (25.4 cm)
B = 6-inches (15.24 cm)

10 American Dryer Corp. 113279-9
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
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
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: 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 in WC. 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.”
The ductwork for this appliance must be suitable for the
appliance category in accordance with national installation
regulations of the country of destination.
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.
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 (6.10 meters). The diameter of this
ductwork must be 4-inches (10.2 cm). Including tumbler/
dryerelbow connectionsor elbowsused foroutsideprotection
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.
Vertical Venting
Whenvertical dryerventing isused, thelength ofthe ductwork
from the dryer to the outside exhaust outlet, must not exceed
12 feet (3.66 meters). The diameter of this ductwork must
be 4-inches (10.2 cm). Including tumbler/dryer elbow
connections or elbows used for outside protection from the
weather, nomore than3 elbowsshouldbe usedin theexhaust
duct run. If more than 3 elbows are used, the cross-sectional
area of the ductwork must be increased.

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.
Thereare twotypes ofdevicesused tomeasure gaspressure.
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
highlyaccurate. Amanometer issimply aglass ortransparent
plastictube witha scalegraduated ininches ormillibar. 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 (refer to the illustration on page 15).
60Hz dryers:Installpressure tap andattachmanometer(refer
to the illustration on page 15).
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.
If the gas pressure needs to be adjusted, refer to “Gas

dryer, and test for leaks.
Operate the dryer through one complete cycle to ensure
proper operation.
With dryer operating, check the manifold (burner) pressure
at the tap on the gas valve to ensure proper operating
pressure (refer to chart on page 14).
Gas Pressure Adjustment
Disconnect electrical power to the dryer.
To adjust gas valve’s internal regulator, remove the regulator
vent cap. Once vent cap is removed, 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. If it is not correct, you must discontinue the power
tothe unit andmake furtheradjustments. Repeat thesesteps
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.

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.
Agas 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 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.
Electrical Dryers
Check to ensure that electric oven/contactor assembly is
activating.
Safety Related Circuits

Routine Maintenance _________________
Cleaning
Aprogram 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
After Each Load
Clean the lint screen after each load. Aclogged lint screen
will cause poor dryer performance. The lint door is located
just below the loading door of the dryer. Open the lint door,
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 area.
!
WARNING
To avoid the hazard of electrical shock, discontinue
electrical supply to the dryer.
90 Days
Remove lint from gas valve burner area with a dusting brush
or vacuum cleaner attachment.
Cleanany lintaccumulation inand aroundthe 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 removed. Once they are
removed 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.
Aback 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 lint box.
When cleaning the dryer cabinet(s), avoid using harsh
abrasives. Aproduct intended for the cleaning of
appliances is recommended.
7 Days After Installation
and Every 12 Months Thereafter
Acompetent professional should inspect bolts, nuts, screws,
setscrews, grounding connections and nonpermanent gas
connections (unions, shutoff valves, and orifices). Belts
shouldbe examined. Crackedor seriouslyfrayed 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).
