Installation
Position and Level the Tumble Dryer
The tumble dryer may be moved with or without the
skid. To remove the skid, unscrew the four shipping
bolts, and discard them.
To fit a 170 pound tumble dryer (with shipping skid)
through an 8 foot (2.43 meters) high door, you must
remove the front access panel. The upper 3 inches
(76 mm) of the stove must also be removed on
170 pound gas tumble dryers. Removing the entire gas
or steam heater assembly and the shipping skid, will
reduce the height of the 120 pound tumble dryer to 70
inches (1778 mm), and the 170 pound tumble dryer to
75 inches (1905 mm).
Level the tumble dryer to within 0.125 inch (3 mm)
from front-to-rear (level on cylinder rib), and side-toside (level on top panel). Shim under corners to level
and stabilize unit. Tumble dryer must not rock.
Before Placing Tumble Dryer into
Service
1. Remove or open all panels and check accessible
bolts, nuts, screws, terminals and fittings for
tightness.
2. Check V-belt tension and adjust if necessary.
Refer to appropriate paragraphs in Adjustments
Section.
3. Replace all panels and guards.
4. Turn on electrical supply to tumble dryer.
5. Open supply valve for gas or steam heated
tumble dryers.
7. Gas tumble dryers: Start the tumble dryer and
check the burner flame. Adjust the gas inlet
shutter as required. Refer to Adjustments section.
IMPORTANT: The Electronic Ignition system will
attempt to light the gas by sparking for the “trial
for ignition” period. If gas does not ignite within
this period, the ignition control will go into a safety
lockout and the valve will no longer open until the
control is reset. Refer to Table 1. It may be
necessary to restart several times to bleed air out of
gas lines. To reset, open and close loading door,
then start.

General Information
This information is to be used when installing gas
tumble dryers in countries, and/or on gases, different
than the machine’s factory configuration. Tumble
dryers are supplied from the factory for operation on
Natural Gas 1000 Btu/cu. ft. (8914 kcal/m3), or L.P.
Gas 2500 Btu/cu. ft. (22,250 kcal/m3) in the countries
of GB/IE/PT/ES/IT/GR/LU/CH. To install machines
in any other country or on any other gas requires some
level of modification.
20
Models are built in two different configurations:
 Regulated Natural Gas – Injector is sized for
Natural Gas, second family, group H (E) at
20 mbar inlet pressure. Regulator/governor is
operational. Gas valve CAN be field converted to
a non-regulating type.
 Unregulated L.P. (Liquefied Petroleum) Gas –
Injector is sized for L.P. Gas, third family, group
3+ at 28.37 mbar inlet pressure. Regulator/
governor is blocked open. Gas valve CAN be
field-converted to a regulating type.
Serial plates supplied from the factory are configured
for the countries of GB/IE/PT/ES/IT/GR/LU/CH.
These instructions pertain to the situations when the
country of use or gas supply is different than that on
the serial plate.
Table 2 describes the different gases that are available
in different CE countries, and how the machines need
to be configured to operate with those gases. In the
CE, there are Natural Gas configurations that do not
allow for machine regulation, and L.P. Gas
configurations that must be regulated. For L.P. Gas,
third family B/P at 50 mbar, order Regulated Natural
Gas machines and convert according to Table 2.

Exhaust Requirements
Make-up air openings with louvers will restrict air
flow. The opening must be increased to compensate
for area taken up by louvers.
WARNING
A drying tumble dryer produces
combustible lint. To reduce the risk of fire,
the tumble dryer must be exhausted to the
outdoors.
W057R1
To reduce the risk of fire and accumulation
of combustible gases, DO NOT exhaust
tumbler air into a window well, gas vent,
chimney or enclosed, unventilated area
such as an attic, ceiling, crawl space under
a building, or concealed space of a
building.
W506
Make-up air openings in rooms containing tumble
dryer(s) and/or gas fired hot water heater or other
gravity vented appliances must be increased
sufficiently to prevent downdrafts in any of the vents
when all tumble dryers are in operation. Do not locate
gravity vented appliances between tumble dryer(s) and
make-up air openings. If it is necessary to duct makeup air to tumble dryer(s), increase area of duct work by
25% to compensate for any restriction in air
movement.
Venting
WARNING
Layout
Wherever possible, install tumble dryers along an
outside wall, where duct length can be kept to a
minimum and makeup air can be easily accessed.
Construction must not block the airflow at the top rear
of the tumble dryer. Doing so would prevent adequate
air supply to the tumble dryer combustion chamber.
Make-Up Air
A tumble dryer is forced air exhausted and requires
provisions for make-up air to replace air exhausted
by tumble dryer. Refer to Table 3.
IMPORTANT: Do not obstruct flow of combustion
and ventilation air.

Table 3
To reduce the risk of fire due to increased
static pressure, we do not recommend
installation of in-line secondary lint filters
or lint collectors. If secondary systems
are mandated, frequently clean the
system to assure safe operation.
W749
IMPORTANT: Installing in-line filters or lint
collectors will cause increased static pressure.
Failure to maintain the secondary lint system will
decrease tumble dryer efficiency and may void
machine warranty.
For maximum efficiency and minimum lint
accumulation, tumble dryer must be exhausted to the
outdoors by the shortest possible route.
Proper sized exhaust ducts are essential for proper
operation. All elbows should be sweep type. Exhaust
ducts must be assembled so the interior surfaces are
smooth, so the joints do not permit the accumulation
of lint. DO NOT use plastic, thin foil or Type B
flexible ducts – rigid metal ducts are recommended.
Use exhaust ducts made of sheet metal or other
noncombustible material. Use of duct tape or poprivets on all seams and joints is recommended, if
allowed by local codes.
Verify that old ducts are thoroughly cleaned before
installing new tumble dryer(s).

Exhaust Requirements
Alternate Venting for 120 Pound tumble dryers
WARNING
The 120 pound tumble dryer is equipped from the
factory to exhaust from the top; however, it may be
converted to exhaust out the rear by doing the
following (refer to Specifications and Dimensions
section):
Improperly sized or assembled ductwork
causes excess back pressure which
results in slow drying, lint collecting in the
duct, lint blowing back into the room, and
increased fire hazard.
1. Remove belt guard cover.
W355
NOTE: Exhaust ducts must be constructed of sheet
metal or other noncombustible material. Such
ducts must be equivalent in strength and corrosion
resistance to ducts made of galvanized sheet steel
not less than 0.0195 inch (0.495 mm) thick.
Where the exhaust duct pierces a combustible wall or
ceiling, the opening must be sized per local codes. The
space around the duct shall be sealed with
noncombustible material.
NOTE: For best performance, provide an
individual exhaust duct for each tumble dryer. Do
not install a hot water heater in a room containing
tumble dryers. It is better to have the water heater
in a separate room with a separate air inlet.
2. Remove 10 inch (254 mm) diameter elbow and
vertical duct.
3. Cut out shape from belt guard cover. Refer to
Figure 5.
4. Screw octagonal piece over 10 inch (254 mm)
diameter opening in top of belt guard.
5. Attach new exhaust duct to exhaust thimble on
rear panel, following all requirements in this
section.
6. Replace belt guard cover.

Exhaust Requirements
Individual Venting
For maximum efficiency and performance, it is
preferred to exhaust tumble dryer(s) individually to
the outdoors.
IMPORTANT: At no point may the cross sectional
area of installed venting be less than the cross
sectional area of the exhaust outlet of the tumble
dryer.
The exhaust duct must be designed so the static back
pressure measured 12 inches (305 mm) from the
exhaust outlet does not exceed the maximum
allowable pressure specified on the installation sticker
on the rear of the tumble dryer.
NOTE: Static back pressure must be measured
with the tumble dryer running.
The maximum allowable length of venting of the same
diameter as the exhaust thimble is 14 feet (4.3 meters)
and two 90° elbows or equivalent. If the equivalent
length of a duct required for an installation exceeds the
maximum allowable equivalent length, the diameter of
a round duct must be increased by 10% for each
additional 20 feet (6.1 meters). Cross section area of a
rectangular duct must be increased by 20% for each
additional 20 feet (6.1 meters). Refer to Table 4 to
determine equivalent venting:
Equivalent Length
of Rigid Straight Duct
10 in. (254 mm) One 90° elbow = 11.6 ft. (3.5 m)
12 in. (305 mm) One 90° elbow = 14 ft. (4.3 m)
14 in. (356 mm) One 90° elbow = 16 ft. (4.9 m)
16 in. (406 mm) One 90° elbow = 18.7 ft. (5.7 m)
18 in. (457 mm) One 90° elbow = 21 ft. (6.4 m)
Equivalent Length (ft.) = 1.17 x Duct Diameter (in.)
NOTE: The maximum length of a flexible metal
duct must not exceed 7.87 ft. (2.4 m) as required to
meet UL2158, claus 7.3.2A.
Manifold Venting
While it is preferable to exhaust tumble dryers
individually to the outdoors, a main collector duct may
be used if it is sized according to Figure 8. This
illustration indicates minimum diameters, and should
be increased if collector length exceeds 20 feet (6.1
meters). Manifold duct may be rectangular in cross
section, as long as area is not reduced. Provisions
should be made for lint removal and cleaning of duct.
Manifold duct must be tapered, as shown in Figure 6.
Individual tumble dryer ducts must enter manifold
duct at a 45° angle in the direction if airflow.
NOTE: Never connect a tumble dryer duct at a 90°
angle to a collector duct. Refer to Figure 6. Doing
so will cause excessive back pressure, resulting in
poor performance. Never connect two tumble
dryer exhaust ducts directly across from each other
at the point of entry to manifold duct.
Duct Diameter
Table 4
Example: A 12 inch (305 mm) diameter duct’s
equivalent length of 14 feet (4.3 meters) of duct and two
90° elbows is:
Equivalent Length: = 14 ft. (4.3 m) + (2) 90° elbows
= 14 ft. (4.3 m) + 14 ft. (4.3 m)
+ 14 ft. (4.3 m)
= 42 ft. (12.8 m)
With the tumble dryer in operation, airflow at any
point in the duct should be at least 1200 feet per
minute (366 meters per minute) to ensure that lint
remains airborne. If 1200 feet per minute (366 meters
per minute) cannot be maintained, schedule monthly
inspections and cleaning of the ductwork.
70420801 (EN)
T438I
Figure 6
Exhaust system must be designed so static back
pressure measured 12 inches (305 mm) from exhaust
thimble does not exceed maximum allowable pressure
specified on installation sticker on rear of tumble
dryer. This must be measured with all tumble dryers
running that are vented into collector.
With the tumble dryer in operation, airflow at any
point in the duct should be at least 1200 feet per
minute (366 meters per minute) to ensure that lint
remains airborne. If 1200 feet per minute (366 meters
per minute) cannot be maintained, schedule monthly
inspections and cleaning of the ductwork.

WARNING
To reduce the risk of fire or explosion, DO
NOT CONNECT THE GAS LINE TO THE
TUMBLE DRYER IF THE GAS SERVICE IS
NOT THE SAME AS THAT SPECIFIED ON
THE TUMBLE DRYER SERIAL PLATE! It
will first be necessary to convert the gas
burner orifice and gas valve. Appropriate
conversion kits are available.
W060R1
IMPORTANT: Any product revisions or conversions
must be made by the Manufacturer’s Authorized
Dealers, Distributors or local service personnel.
WARNING
The tumbler and its individual shut-off
valve must be disconnected from the gas
supply piping system during any
pressure testing of that system at test
pressures in excess of 0.5 psig (3.45 kPa).
The tumbler must be isolated from the
gas supply piping system by closing its
individual manual shut-off valve during
any pressure testing of the gas supply
piping system at test pressure equal to or
less than 0.5 psig (3.45 kPa).
W061R2
IMPORTANT: The installation must comply with
local codes or, in the absence of local codes:
 with the latest edition of the “National Fuel
Gas Code,” ANSI Z223.1/NFPA 54 in the
U.S.A.
 with CAN/CSA-B149.1 Natural Gas and
Propane Installation Code in Canada
 and Gas Installations Standard AS/NZS 5601
Part 1: General Installations in Australia and
New Zealand
Obtain specific gas service pipe size from the gas
supplier. Refer to Table 7 for general pipe size.
70420801 (EN)
The following must be furnished and installed by the
customer for the gas service line to each tumble dryer.
Refer to Figure 10.
 Sediment traps
 Shut-off valves
 Supply pressure taps
It is important that equal pressure be maintained at all
tumble dryer gas connections. This can be done by
installing a one inch (25 mm) pipe gas loop. Refer to
Figure 11.
WARNING
To reduce the risk of fire or explosion, if
the tumble dryer is to be connected to
Liquefied Petroleum (L.P.) gas, a vent to
the outdoors must be provided in the
room where the tumble dryer is installed.
W062R1
NATURAL GAS recommended line pressure is 6.5
water column inches (1.62 kPa), with no less than 5
water column inches (1.24 kPa) and no more than 10.5
water column inches (2.61 kPa), with all gas
appliances running (tumble dryers, water heaters,
space heaters, furnace, etc.). An in-line pressure
regulator may be required if the line pressure exceeds
10.5 water column inches (2.61 kPa) with all gas
appliances running.
LIQUID PETROLEUM GAS (L.P.) line pressure must
be maintained at 11 water column inches (2.74 kPa),
with no less than 10 water column inches (2.49 kPa)
and no more than 13 water column inches (3.23kPa),
with all gas appliances running (tumble dryers, water
heaters, space heaters, furnace, etc.).

Grounding Instructions
This tumble dryer must be grounded. In the event of
malfunction or breakdown, grounding will reduce the
risk of electric shock by providing a path of least
resistance for electric current. This tumble dryer must
be connected to a grounded metal, permanent wiring
system; or an equipment grounding conductor must be
run with the circuit conductors and connected to the
appropriate ground location.
Metal conduit and/or BX cable is not considered
ground. Connecting the Neutral from the electrical
service box to the tumble dryer ground screw does not
constitute a ground. A dedicated ground conduit (wire)
must be connected between the electrical service box
ground bar and the tumble dryer ground screw.

NOTE: The wiring diagram is located in the
junction or contactor box.
1. Install a circuit breaker as close to the tumble
dryer as possible. If more than one tumble dryer
is being installed, a circuit breaker should be
provided for each. This will make it possible to
disconnect each tumble dryer for maintenance
purposes.
2. Connect conduit-encased leads to the circuit
breaker. Connect wire leads to the appropriate
labeled terminal on the terminal block. The
ground wire must be connected to the ground
connection as shown in Figure 12.
3. Check the electrical service phase sequence
(three phase only). If one of the power leads is a
“high leg,” connect it to lead L3 in the tumble
dryer. The cylinder must rotate clockwise and the
fan must rotate counterclockwise (as viewed
from the front of the tumble dryer – with selector
switch in non-reverse position). If not,
interchange leads L1 and L2 in the tumble dryer
connection box.

Steam Requirements
NOTE: Machines require a constant 80 to 100 psig
(5.62 to 7.03 kg/sq. cm) steam service for optimum
operation. The maximum allowable steam pressure
for use with 60 Hertz or 50 Hertz tumble dryers is
125 psig (8.6 bar). In no case may the pressure
exceed the above value. Drying performance is
significantly reduced at lower steam pressures.
Obtain specific steam service pipe sizes from steam
system supplier or a qualified steam fitter.
 Refer to Figure 14 and Figure 15 for proper
steam pipe configurations.
NOTE: To prevent water hammering, route return
lines below outlets of steam coils.
Piping Recommendations
 Trap each steam coil individually. Always keep
the trap clean and in good working condition.
 When tumble dryer is on the end of a line of
equipment, extend header at least 4 feet
(1.2 meters) beyond tumble dryer. Install shut-off
valve, union, check valve and bypass trap at end
of line. If gravity return to boiler, omit trap.
 To prevent condensate draining from headers to
tumble dryer, piping should have a minimum
12 inch (305 mm) rise above respective header.
Do not make steam connection to header with a
horizontal or downward facing tee or elbow.
 Insulate steam supply and return line for safety of
operator and safety while servicing tumble dryer.
 Whenever possible, horizontal runs of steam
lines must drain, by gravity, to respective steam
header. Water pockets or an improperly drained
steam header will provide wet steam, causing
improper operation of tumble dryer. If pockets or
improper drainage cannot be eliminated, install a
bypass trap to drain condensate from the low
point in the steam header to the return.
WARNING
 In both steam supply and steam return line, it is
recommended that each have a pipe union and
shut-off valve. This will enable you to disconnect
the steam connections and service the tumble
dryer while your laundry facility is in operation.
 Keep tumble dryer in good working condition.
Repair or replace any worn or defective parts.
All system components must have a
125 psig (8.6 bar) working pressure.
Shut-off valves must be installed upstream
of the steam solenoid valve and
downstream of each steam trap so
components can be isolated for
maintenance or emergency purposes.
All components (solenoid valve, traps)
must be supported to minimize loads on
the tumble dryer steam coil connections.
W480R2
 Connect the steam solenoid valve to the related
steam coil inlet connection with nipples, flex
hoses, unions and tee.
 Strainers may require cleaning due to materials
from hoses or pipes.
 Install vacuum breaker (optional), bucket trap
with built-in strainer and check valve. For
successful operation of tumble dryer, install trap
18 inches (457 mm) below coil and as near to the
tumble dryer as possible. Inspect trap carefully
for inlet and outlet markings and install
according to trap manufacturer's instructions. If
steam is gravity returned to boiler, omit trap but
install vacuum breaker and check valve in return
line near tumble dryer.
 Gravity return requires entire return plumbing be
below steam coil outlets.
 Install union and shut-off valve in return line and
make final pipe connections to return header.

connections must be connected to the condensate
return lines. The following steps outline the procedure
for installing the steam trap and connecting the
condensate return lines. Refer to Figure 14 and
Figure 15 for typical installations.
1. Use flexible lines between steam inlet solenoid
and steam coils, as well as outlet between steam
coil and traps.
Thermal Oil Prep
It is the responsibility of the customer to install
appropriate coil and heating system for thermal oil
prep models. Alliance Laundry Systems, LLC. is not
responsible for the performance or safety of the
customer installed thermal oil system. To ensure
proper operation, refer to the Specifications and
Dimensions section for the BTU input of equivalent
steam models. Thermal oil systems that do not deliver
appropriate BTUs will dry slower. For solenoid valve
wiring connections, refer to the Wiring Diagram
supplied with tumble dryer.
2. If necessary, install a strainer to the end of each
flexible hose.
3. Install a steam trap to each strainer.
IMPORTANT: Steam trap must be installed a
minimum of 18 inches (457 mm) below the steam
coil outlet connections.
4. Install a shut-off valve to each steam trap.
5. Connect to the condensate return lines.
6. For steam solenoid valve wiring connections,
refer to Wiring Diagram supplied with tumble
dryer.
WARNING
All system components must have a
125 psig (8.6 bar) working pressure.
Shut-off valves must be installed
upstream of the steam solenoid valve and
downstream of each steam trap so
components can be isolated for
maintenance or emergency purposes.
All components (solenoid valve, traps)
must be supported to minimize loads on
the tumble dryer steam coil connections.

W002R1
INSUFFICIENT AIRFLOW
Gas Burner Air Shutter
NOTE: Air inlet shutters on the burner must be
adjusted so sufficient air is metered into the system
for proper combustion and maximum efficiency.
Before adjusting the inlet shutters, be sure that all
lint is removed from lint compartments and lint
screen.
1
Air shutter adjustment will vary from location to
location and will depend on the vent system, number
of units installed, make-up air and line gas pressure.
Opening the shutter increases the amount of primary
air supplied to the burner, while closing the shutter
decreases the primary air supply. Adjust air shutter as
follows:
NO AIRFLOW
Refer to Figure 16.
1. Remove the upper access panel and burner
inspection hole plate.
2. Start the tumble dryer and check the flame
pattern. If the flame pattern is straight up,
insufficient air is flowing through the tumble
dryer. A flame pattern that flares to the right and
left indicates no air is flowing through the tumble
dryer. Correct air and gas mixture is indicated if
the flame pattern is primarily blue, with small
yellow tips, and bends to the left of the heater
section. Too little air is indicated if the flame is
yellow, lazy and smoky.

WARNING
The tumble dryer must not be operated if
the airflow switch does not operate
properly. Faulty airflow switch operation
may cause an explosive gas mixture to
collect in the tumble dryer.
W072R1
IMPORTANT: Airflow switch vane must remain
closed during operation. If it opens and closes
during the drying cycle, this indicates insufficient
airflow through the tumble dryer. If switch remains
open, or pops open and closed during the cycle, the
heating system will shut off. The cylinder and fan
will continue to operate even though the airflow
switch is indicating insufficient airflow.
NOTE: To properly mount the airflow switch
bracket, or in case of a load not drying, the airflow
switch bracket may need to be checked for proper
alignment. Be sure the locator pins are securely in
their respective holes before tightening the bracket
mounting screws. This will assure proper
alignment of the airflow switch arm in the channel
of the airflow switch bracket and prevent binding
of the arm.

Belt Drive
The drive assemblies consist of motors, belts, eyebolts
and a step pulley.
The pulley diameters are sized to produce a cylinder
speed of 37-39 RPM for 120 pound models or
29-31 RPM for 170 pound models.
The step pulley assembly is used for speed reduction
as well as a means of adjusting belt tension. The pulley
mounting plate is attached to the cabinet. The frame
mounting plate has vertically slotted holes allowing up
and down movement of the step pulley mounting plate
for belt adjustment.
Adjust the belt tension as follows:
1. Disconnect electrical power to the tumble dryer
before attempting any adjustments to the drive
assembly.
2. Loosen pulley mounting plate bolts.
3. Loosen the upper nut on the final drive eyebolt.
4. Rotate the lower nut of the final drive eyebolt
clockwise until proper belt tension is achieved.
70420801 (EN)
5. Rotate upper nut clockwise against the lower nut
in order to lock it into place.
6. Tighten pulley mounting plate bolts. Recheck
belt tension.
7. If necessary, adjust the drive motor belt tension
eyebolt using a similar procedure.
8. Adjust blower belt tension on 120 pound
50 Hertz tumble dryers and all 170 pound tumble
dryers using a similar procedure.
NOTE: Proper tensions for new belts are
45-55 pounds for the motor belt, 55-65 pounds for
the final drive, 60-65 pounds for 120 pound blower,
and 75-80 pounds for 170 pound blower measured
with a Borroughs Belt Tension Gauge. Using a
Browning Belt Tension Gauge, the motor belt
deflection should be 0.31 inch at five pounds
pressure, and final drive belt deflection should be
0.25 inch at five pounds pressure.
Belts should not slip or make any noise when starting
up under normal load.
