the lint panel. The heating systems should shut
off when the lint panel is opened a maximum of
1-1/2 inches (38 mm).
The airflow switch operation may be affected by
shipping tape still in place, lack of make-up air,
or an obstruction in the exhaust duct. These
should be checked and the required corrective
action taken before attempting to adjust the
airflow switch. To adjust the airflow switch refer
to Adjustments Section.
10. Wipe out the cylinder using an all-purpose
cleaner or detergent and water solution. Refer to

Installing Gas Drying Tumblers in
the European Union (EU)
General Information
This information is to be used when installing gas
tumblers in countries and/or on gases different than the
machine’s factory configuration. Tumblers are
supplied from the factory for operaton on Natural Gas
or L.P. Gas in the countries of GB/IE/PT/ES/IT. To
install machines in any other country or on any other
gas requires some level of modification.
Models are built in three 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 Natural Gas – Injector is sized for
Natural Gas, second family, group E+ at
20.25 mbar inlet pressure. Regulator/governor is
blocked open. Gas valve CAN be field-converted
to a regulating type.
●Unregulated L.P. (Liquified 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 one of the three gases for the countries of GB/IE/
PT/ES/IT. This information pertains to situations when
the country of use or gas supply is different than that
on the serial plate.
Table 3, Table 4 and Table 5 describe the different
gases that are available in different EU countries, and
how the machines need to be configured to operate
with those gases. In the EU, there are Natural Gases
that do not allow for machine regulation, and L.P.
Gases that must be regulated. For L.P. Gas, third
family B/P at 50 mbar, order Regulated Natural Gas
machines and convert according to tables.
WARNING
To reduce the risk of electric shock, fire,
explosion, serious injury or death:
• Disconnect electric power to the
tumbler before servicing.
• Close gas shut-off valve to gas tumbler
before servicing.
• Close steam valve to steam tumbler
before servicing.
• Never start the tumbler with any guards/
panels removed.
• Whenever ground wires are removed
during servicing, these ground wires
must be reconnected to ensure that the
tumbler is properly grounded.

Exhaust Requirements
Layout
Whenever possible, install tumblers along an outside
wall where duct length can be kept to a minimum, and
make-up air can be easily accessed. Construction must
not block the airflow at the rear of the tumbler. Doing
so would prevent adequate air supply to the tumbler
combustion chamber.
Make-Up Air
A tumbler is forced air exhausted and requires provisions
for make-up air to replace air exhausted by tumbler.
Refer to Table 6.
IMPORTANT: Do not obstruct flow of combustion
and ventilation air.
Table 6
Make-up air openings with louvers will restrict
airflow. The opening must be increased to compensate
for area taken up by louvers.
Make-up air openings in rooms containing tumbler(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 tumblers are in
operation. Do not locate gravity vented appliances
between tumbler(s) and make-up air openings. If it is
necessary to duct make-up air to tumbler(s), increase
area of ductwork by 25% to compensate for
restrictions in airflow.
Venting
For maximum efficiency and minimum lint
accumulation, tumbler air 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 or thin foil flexible ducts.
Use exhaust ducts made of sheet metal or other
noncombustible material. Use duct tape on all joints.
Verify that old ducts are thoroughly cleaned out before
installing new tumbler.
Improperly sized or assembled ductwork causes
excess back pressure which results in slow drying, lint
collecting in the duct, lint blowing into the room, and
increased fire hazard.
Exhaust ducts shall 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 inches (0.495 mm) thick.
Where the exhaust duct pierces a combustible wall,
ceiling, floor or partition an opening having a diameter
of 4 inches (102 mm) larger than the diameter of the
exhaust duct shall be provided, with the duct centered
in the opening. The space around the duct may be
sealed with noncombustible material. Refer to Figure 10.
IMPORTANT: For best performance provide an
individual exhaust duct for each tumbler. Do not
install a hot water heater in a room containing
tumblers. It is better to have the water heater in a
separate room with a separate air inlet.

WARNING
A drying tumbler produces combustible
lint. To reduce the risk of fire, the tumbler
must be exhausted to the outdoors.
W057
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 wall,
ceiling, crawl space under a building, or
concealed space of a building.
W059

Individual Venting
For maximum efficiency and performance, it is
preferred to exhaust tumbler(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 tumbler.
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
tumbler. Static back pressure must be measured with the
tumbler running (both pockets on stacked models).
The maximum allowable length of venting of the same
diameter as the exhaust thimble is 14 feet (4.3 m) 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 Tabl e 7 to
determine equivalent venting.
Example: A 12 inch diameter duct’s equivalent
length of 14 feet of duct and two 90° elbows is:
Equivalent Length = 14 ft. + (2) 90° elbows
= 14 ft. + 14 ft. + 14 ft.
= 42 ft. (12.8 m)
With the tumbler 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 cannot be maintained,
schedule a regular inspection and cleaning of the
ductwork.

Manifold Venting
While it is preferable to exhaust tumblers individually
to the outdoors, a main collector duct may be used if it
is sized according to Figure 12. This illustration
indicates minimum diameters, and should be increased
if the collector length exceeds 14 feet (4.2 meters) and
two 90° elbows. The diameter of a round duct must be
increased by 10% for each additional 20 feet
(6.1 meters). Cross sectional area of a rectangular or
square duct must be increased 20% for each additional
20 feet (6.1 meters). Refer to Tabl e 8 to determine
equivalent ducting sizing. The collector duct may be
rectangular or square in cross section, as long as the
area is not reduced. Provisions MUST be made for lint
removal and cleaning of the collector duct.
The vent collector system 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 tumbler. Static back pressure must be
measured with all tumblers vented into the collector
operating.
Never connect a tumbler duct at a 90° angle to the
collector duct. Refer to Figure 11. Doing so will
cause excessive back pressure, resulting in poor
performance. Never connect two tumbler exhaust
ducts directly across from each other at the point of
entry to the collector duct.
With the tumbler 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 cannot be
maintained, schedule a regular inspection and cleaning
of the ductwork.
The collector system 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 tumbler. This must be measured with all tumblers
vented into the collector operating.

Gas Requirements
IMPORTANT: Any product revisions or conversions
must be made by the Manufacturer’s Authorized
Dealers, Distributors or local service personnel.
IMPORTANT: 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 1/2 psig
(3.45 kPa, 34.5 mbar).
IMPORTANT: The tumbler and its manually
operated appliance gas valve must be disconnected
from the gas supply piping system during any
pressure testing of that system at test pressures in
excess of 1/2 psi (3.45 kPa, 34.5 mbar).
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 CSA-B149.1 or Natural Gas and Propane
Installation Code in Canada,
●and Australian Gas Association/Australian
L.P. Gas Association requirements in
Australia.
Obtain specific gas service pipe size from the gas
supplier. Refer to Table 9 for general pipe size.
A dirt and water vapor pipe trap must be furnished and
installed. Refer to Figure 13.
Install a 1 inch (25.4 mm) pipe gas loop to maintain
equal pressure at all gas connections. Refer to
Figure 14.
An in-line pressure regulator may be required on
Natural Gas models if the line pressure exceeds
8 water column inches (2.00 kPa) pressure with all gas
appliances firing.
NATURAL GAS service must be supplied at 7.0 ±
1.5 inch water column pressure (1.74 ± 0.37 kPa).
L.P. (Liquefied Petroleum) GAS service must be
supplied at 11 ± 0.3 inch water column pressure
(2.74 ± 0.07 kPa).
EUROPEAN GASES – The above data for Natural
and L.P. Gas does not apply in the EU. Refer to
Installing Gas Drying Tumblers in the European
Union.
Pressure checks can be made at the shut-off valve.
Refer to Figure 13.
WARNING
To reduce the risk of fire or explosion, DO
NOT CONNECT THE GAS LINE TO THE
TUMBLER IF THE GAS SERVICE IS NOT
THE SAME AS THAT SPECIFIED ON THE
TUMBLER SERIAL PLATE! It will first be
necessary to convert the gas burner
orifice and gas valve. Appropriate
conversion kits are available.
W060
WARNING
To reduce the risk of fire or explosion, if
the tumbler is to be connected to
Liquefied Petroleum (L.P.) gas, a vent to
the outdoors must be provided in the

Turn on gas and check all pipe connections (internal
and external) for gas leaks with a non-corrosive leak
detection fluid. Purge air in gas service line by
operating the tumblers in the drying mode. If burner
does not light and unit goes into lockout, open and
close the door and restart. Repeat these steps until
burner ignites. Use pipe compound, resistant to
actions of L.P. Gas, on all pipe threads.

Steam Requirements
Obtain specific steam service pipe sizes from steam
system supplier or a qualified steam fitter.
●Refer to Figure 15 for proper steam pipe
configurations.
●To prevent condensate draining from headers to
tumbler, 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.
●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 tumbler. 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.
●In both steam supply and steam return line, it is
recommended that each have a pipe union and
globe valve. This will enable you to disconnect
the steam connections and service the tumbler
while your laundry facility is in operation.
●Before connecting trap and check valve to
tumbler, open shut-off valve in steam supply line
and allow steam to flow through tumbler to flush
out any dirt and scale from tumbler. This will
assure proper operation of trap when connected.
●After flushing system, install vacuum breaker,
inverted bucket trap (with built-in strainer) and
check valve. For successful operation of tumbler,
install trap 18 inches (457 mm) below coil and as
near to the tumbler 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 tumbler. 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.
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 tumbler is on the end of a line of
equipment, extend header at least 4 feet
(1.2 meters) beyond tumbler. Install shut-off
valve, union, check valve and bypass trap at end
of line. If gravity return to boiler, omit trap.
●Insulate steam supply and return lines for safety
of operator and safety while servicing tumbler.
●Keep tumbler in good working condition. Repair
or replace any worn or defective parts.
Machines require a (constant) 80 to 100 psig (pounds
per square inch gauge) (5.62 to 7.03 kg/sq. cm) steam
service for optimum operation.
WARNING
All system components must have a
125 psig (10 bar) working pressure.
Shut-off gate 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 tumbler steam coil connections.

Installing Steam Trap and Making
Condensate Return Connections
The steam trap must be installed and the coil outlet
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 15 for typical
installations.
1. Connect a flexible hose to each steam coil outlet.
2. Install a strainer to the ends 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 globe shut-off valve to each steam trap.
5. Connect to the condensate return lines.
WARNING
The flexible steam hoses connecting the
coil outlet connections and steam traps
must have a minimum of 125 psig
(pounds per square inch gauge) (8.79 kg/
sq. cm.) working pressure. A shut-off
valve must be installed downstream from
each steam trap so the condensate return
line can be isolated in event a steam trap
requires maintenance.
Each steam trap must be supported so
minimum load is exerted on the coil outlet
connection.

Grounding Instructions
NOTE: To ensure protection against shock, this
tumbler MUST be electrically grounded in
accordance with the local codes or, in the absence of
local codes, with the latest edition of the National
Electrical Code ANSI/NFPA No. 70. In Canada the
electrical connections are to be made in accordance
with CSA C22.1 latest edition Canadian Electrical
Code or local codes. Electrical work should be done
by a qualified electrician.
This tumbler 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 tumbler 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 tumbler ground screw does not
constitute a ground.
●A dedicated ground conduit (wire) must be
connected between the electrical service box
ground bar and tumbler ground screw.
For CE Marked Models Only:
All OPL (non-vend) models are factory-equipped with
an emergency stop button on the front panel.
NOTE: Activation of the emergency stop button
stops all machine control circuit functions, but
DOES NOT remove all electrical power from

WARNING
To reduce the risk of electric shock, fire,
explosion, serious injury or death:
• Disconnect electric power to the
tumbler before servicing.
• Close gas shut-off valve to gas tumbler
before servicing.
• Close steam valve to steam tumbler
before servicing.
• Never start the tumbler with any guards/
panels removed.
• Whenever ground wires are removed
during servicing, these ground wires
must be reconnected to ensure that the
tumbler is properly grounded.
W002
To reduce the risk of fire and electric
shock, check with a qualified serviceman
for proper grounding procedures.
Improper connection of the equipment
grounding conductor may result in a risk
of electric shock.
W068
To reduce the risk of fire and electric
shock, if electrical supply is coming from
a three phase service, DO NOT connect a
“High Leg” or “Stinger Leg” to a single
phase machine. On a three phase
machine, if there is a “High Leg” or
“Stinger Leg” it should be connected to
L3.
W069
WARNING
To reduce the risk of electrical shock,
de-energize the electrical circuit being
connected to the tumbler before making
any electrical connections. All electrical
connections should be made by a
qualified electrician. Never attempt to

The following steps outline the procedure for
connecting the electrical service to the tumbler.
NOTE: The wiring diagram is supplied in
literature packet in cylinder.
1. Install a circuit breaker as close to the tumbler as
possible. If more than one tumbler is being
installed, a disconnect switch or circuit breaker
should be provided for each. This will make it
possible to disconnect each tumbler for
maintenance purposes.
2. Connect the conduit-encased leads to the disconnect
switch, or circuit breaker. Connect the 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 16.
3. Check the electrical service phase sequence
(three phase only) as follows:
a. Energize the electrical service (on reversing
tumblers, ensure nonreversing is selected) and
momentarily start the tumbler. Check the
direction of the cylinder rotation. If the
cylinder rotates clockwise (viewed from the
front), the phase sequence is correct. If the
cylinder rotates counterclockwise, proceed
with step b.
NOTE: On reversing tumblers, the fan
motor should also rotate clockwise (viewed
from the front) on all models except the
F75 models which rotate counterclockwise
(viewed from the front).
b. Disconnect and reverse any two service leads
on the terminal block.

configuration jumper may result in damage to
sensitive electronic controls and may void warranty.
Ferrite Ring Installation
Gas and Steam OPL Micro Control Models Only
The ferrite ring provided in the literature packet must
be installed over the power leads during connection of
electrical service. The ferrite protects the sensitive
electronic controls from destructive electrical
disturbances which may be present on power lines to
the machine. Failure to properly install the ferrite ring
may result in damage to the electronic controls and
will void control warranty.
To install:
1. Immediately after connection of power leads and
before applying power to machine, locate each of
the incoming service leads including ground.
2. Snap the ferrite ring closed over all the service
leads inside of the contactor box as shown. It is
important that the ferrite ring be installed inside

Adjustments
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.
Air shutter adjustments 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:
Refer to Figure 18.
1. Open the access panel.
2. Start the tumbler and check the flame pattern. If
the flame pattern is straight up, insufficient air is
flowing through the tumbler and air flow switch
is improperly set. A flame pattern that flares to
the right and left indicates no air is flowing
through the tumbler.
3. Correct air and gas mixture is indicated if the
flame pattern is primarily blue, with small yellow
tips, and bends to the right of the heater section.
Too little air is indicated if the flame if yellow,
lazy and smokey.
4. To adjust the air shutter, loosen air inlet shutter
adjusting screw.
5. Open or close air shutter as necessary to obtain
proper flame intensity.
6. After air shutter is adjusted for proper flame,
tighten air shutter adjusting screw securely.

Airflow Switch
Gas and Electric Tumblers
The airflow switch (located on the rear of tumbler,
Figure 19) is set at the factory for proper operation.
However, if there is a problem with the switch, it
should be adjusted as follows:
NOTE: Steam models do not have an airflow switch.
NOTE: Control panel must be in place and access
door closed before attempting to adjust airflow switch.
IMPORTANT: Airflow switch disc must remain
closed during operation. If it opens and closes
during the drying cycle, this indicates insufficient
airflow through the tumbler. 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 opened.
The airflow switch operation is controlled by the
counterweight position in the shaft. Moving the
counterweight either increases or decreases airflow
switch sensitivity. The counterweight should be
adjusted so the disc moves away from the cabinet
when the lint panel is opened 1.5 inches (38.1 mm) with
a full load. Adjust the airflow switch as follows:
1. Load the tumbler. This adjustment is much faster
to make with one person opening lint panel in
front and another adjusting the counterweight in
the rear of tumbler.
2. Start the tumbler. Open the lint panel 1.5 inches
(38.1 mm). The airflow disc should move away
from the cabinet, opening the switch contacts and
shutting off the heat system. This indicates
proper operation and proper adjustment.
3. If switch is not opening as described in step 2, it
should be adjusted so it is MORE sensitive.
Depress the spring clip and move counterweight
toward disc. Retest by opening lint panel and
continue moving counterweight toward disc until
switch operates as described in step 2.
4. If switch opens BEFORE lint panel is opened the
proper distance, step 2, it should be adjusted so it
is LESS sensitive. Depress the spring clip and
move counterweight away from the disc. Retest
by opening lint panel and continue moving

Loading Door Switch
Non CE Marked Models
The door switch should be adjusted so the cylinder
stops when door is opened 2 inches (51 mm), plus or
minus 1/4 inch (6 mm). This switch is a normally open
switch and is closed by the interlock rod when the
door is closed. If adjustment is required, refer to
Figure 20 and proceed as follows:
1. Close door and start tumbler, slowly open
loading door. Cylinder and heat system should
shut off when door is open 2 inches (51 mm) plus
or minus 1/4 inch (6 mm).
2. Slowly close loading door. When door is 2 inches
from being fully closed, the tab should contact
the interlock rod and depress it enough to operate
the switch arm closing the switch with an audible
“click.”
3. If interlock rod does not depress enough to
operate the switch, bend tab on loading door
OUTWARD 1/8 inch (3 mm) and repeat steps 1
and 2. Bend tab outward an additional 1/8 inch
(3 mm) if required to obtain proper rod
movement and switch operation.
4. If proper operation is not obtained by procedure
outlined in step 3, unlock and open access panel
and remove control panel. Loosen the two
adjusting screws holding the switch to the
bracket and move switch 1/8 inch (3 mm) toward
the front of the switch bracket and retighten the
screws. Repeat steps 1 and 2. If switch and rod
still do not have sufficient movement, move
switch forward an additional 1/8 inch (3 mm).

Chain Drive
There is proper tension when the chain can be
depressed approximately 1/2 inch (13 mm) by
applying light thumb pressure at a point midway
between the cylinder and drive sprocket.
IMPORTANT: After a tumbler has been in
operation over an extended period of time, a “High
Point” will develop on the cylinder drive sprocket
through use and wear. Turn the sprocket manually
with drive chain in place until this “high point” is
at the top center. The “high point” can be found by
noticing increased chain tensionwhile slowly
rotating the cylinder sprocket manually.
Nonreversing Models
Refer to Figure 23.
1. Remove guard from rear of tumbler.
2. Adjust belt first.
3. To adjust chain tension, loosen jam nut holding
idler sprocket to housing.
4. Move idler sprocket left or right until proper
chain tension is reached, then retighten the jam
nut.
5. Replace the guard on rear of tumbler.
Reversing Models
Refer to Figure 24.
1. Remove drive guard.
2. To adjust chain tension, loosen nut on idler
housing attaching bolt. Move entire idler housing
assembly up or down in the guide rails to change
tension.
3. When chain tension is correct, tighten idler
housing attaching bolt. Hold idler housing firmly
in position while tightening nut on attaching bolt.
4. Check chain tension after tightening nut on idler
housing attaching bolt.
WARNING
To reduce the risk of electric shock, fire,
explosion, serious injury or death:
• Disconnect electric power to the
tumbler before servicing.
• Close gas shut-off valve to gas tumbler
