Installation Instructions
RECEIVING INSPECTION
Upon delivery, visually inspect crate carton and parts
for any visible shipping damage. If crate, carton
or cover are damaged or signs of possible damage
are evident, have carrier note condition on shipping
papers before shipping receipt is signed, or advise
carrier of condition as soon as it is discovered.
Advise carrier of any damaged or missing articles as
soon as possible. A written claim should be filed with
carrier immediately if articles are damaged or
missing.
IMPORTANT: Remove shipping tape from two
back draft dampers located in exhaust thimble.
Remove crate and protective cover as soon as
possible and check items listed on packing list.
MATERIALS REQUIRED (Obtain Locally)
GAS, ELECTRIC OR STEAM DRYING
TUMBLERS
•
Two steam shut-off gate valves for each
condensate return line.
•
•
Flexible steam hoses with a 125 psig (pounds per
square inch gauge) (8.79 kg/sq. cm) working
pressure for connecting steam coils, Figures 24
and 25.
•
Two steam traps for steam coil outlet to
condensate return line.
•
One steam pressure relief valve rated at 125 psig.
(8.79 kg/cm2).
One circuit breaker.
GAS DRYING TUMBLERS ONLY
•
One gas shut-off valve for gas service line to each
tumbler.
STEAM DRYING TUMBLERS ONLY
•
One steam shut-off gate valve for steam service
line to be connected upstream of solenoid steam
valve.
FACILITIES REQUIRED
FLOOR
Construction must not block airflow at top rear of
tumbler. Doing so would prevent adequate air supply
to tumbler’s combustion chamber.
Drying tumbler may be installed on any level floor
capable of supporting 100 pounds per square foot
(488 kg/m2). Floor covering materials such as
carpeting or tile should be removed.
VENTING
For maximum efficiency and minimum lint
accumulation, tumbler air must be exhausted to
outdoors by shortest possible route.
LAYOUT
Whenever possible, tumbler should be installed along
an outside wall where duct length can be kept to a
minimum, and make-up air can be easily accessed.
M412616
31
Proper sized exhaust ducts are essential for proper
operation. All elbows should be sweep type. Do not
install elbows with a radius less than shown in table
below. Exhaust ducts must be assembled so interior
surfaces are smooth to reduce accumulation of lint.
Do not use sheet metal screws to join vent sections.
Improperly sized or assembled ductwork causes
excess back pressure which results in slow drying,
lint collecting in duct, lint blowing back into room, and
increased fire hazard.
With tumbler in operation, airflow at any point in
duct must be at least 1200 feet (366 m) per
minute to insure that lint remains airborne.
•
NOTE: This illustration indicates minimum
diameters, and should be increased if collector
length exceeds 20 feet (6.1 m).
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.
Collector duct may be rectangular in cross
section, as long as area is not reduced. Provisions
should be made for lint removal and cleaning of
collector duct.
Where exhaust duct pierces a combustible wall or
ceiling, an opening having a diameter of 4 inches
(10.2 cm) larger than diameter of exhaust duct shall
be provided, with duct centered in opening. When
ducts pass through walls, ceilings, floors or partitions,
space around the duct shall be sealed with noncombustible material. See Figures 1, 2 and 3.
•
Collector duct must be tapered, as shown in
Figure 3. Individual tumbler ducts must enter the
collector duct at a 45° angle in direction of air flow.
Never connect a tumbler duct at a 90° angle to
collector duct. Doing so will cause excessive
back pressure, resulting in poor performance.
Never connect two tumbler exhaust ducts
directly across from each other at point of
entry to collector duct.
Individual Venting
For maximum efficiency and performance, it is
preferred to exhaust tumbler(s) individually to
outdoors. At no point may cross area of
installed venting be less than cross area of
exhaust thimble of tumbler.
Collector system must be designed so static back
pressure measured 12 inches (30.5 cm) from
exhaust thimble does not exceed maximum
allowable pressure specified on installation sticker
on rear of tumbler. Measured with all tumblers
running that are vented into collector.
Maximum allowable length of venting is 14 feet
(4.3 m) and two 90° elbows or equivalent. If
equivalent length of a duct required for an
installation exceeds maximum allowable
equivalent length, diameter of a round duct must
be increased by 10% for each additional 20 feet
(6.1 m). Cross section area of a rectangular duct
must be increased by 20% for each additional 20
feet (6.1 m). Table below shows how to determine
equivalent venting:
DUCT
EQUIVALENT LENGTH OF
DIAMETER
STRAIGHT DUCT
6" (15.2 cm)
8" (20.3 cm)
10" (25.4 cm)
12" (30.5 cm)
Collector Venting
While it is preferable to exhaust tumblers
individually to outdoors, a main collector duct may
be used if it is sized according to Figure 3.
MAKE-UP AIR
A tumbler is forced air exhausted and requires
provisions for make-up air to replace the air
exhausted by tumbler.
Manufacturer’s recommended make-up air opening
for each tumbler is 144 square inches (928 sq. cm)
for 30 and 50 pound tumblers and 195 square inches
(1258 sq. cm) for 75 pound tumblers. At a minimum,
tumblers must have at least 1 in2 (2.54 cm2) of
opening for every 1000 BTU/hr (252 Kcal/hr) of
input rating for proper combustion.
One 90° elbow = 7' (2.1 m)
One 90° elbow = 9.3' (2.83 m)
One 90° elbow = 11.6' (3.5 m)
One 90° elbow = 14' (4.3 m)
Example: A tumbler with a rated input of 120,000
BTU/hr (30,240 Kcal) requires 120 in2
(774 cm2) of free opening.
Protective louvers in opening to outdoors can reduce
air movement by approximately 40%. Opening must
compensate for area taken up by louvers.
Equivalent Length (feet) (m) =
1.17 x Duct Diameter (inches) (cm)
Make-up air openings for a room containing
tumbler(s) and/or gas fired hot water heater or other
gravity vented appliances must be increased
sufficiently to prevent downdrafts in any 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 work by 25% to
compensate for any restriction in air movement.
Example: A 6-inch (15.2 cm) diameter duct’s
equivalent length of 14 feet (4.3 m) of duct
and two 90° elbows is:
Equivalent length
= 14 feet (4.3 m) + (2) 90° elbows
= 14 feet (4.3 m) + 7 feet (2.1 m) + 7 feet (2.1 m)
= 28 feet (8.5 m)
32
M412616
維WARNING
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.
維WARNING
Solvent gases and vapors from dry
cleaning machines create acids when
drawn through the heater of a drying
tumbler. These acids are corrosive to
the drying tumbler as well as to the
laundry load being dried. Be sure
make-up air is free of solvent gases
and vapors.
If the dry cleaning machines are in the
same area as the tumbler, then the
tumbler make-up air must come from
a source free of solvent gases and
vapors.
FOR BEST PERFORMANCE
Provide an individual exhaust
duct for each tumbler. Do not
install a hot water heater in
room containing tumblers. It is
better to have the water heater
in a separate room with a
separate air inlet.
NOTE: Do not install wire
mesh or screen in this
opening as lint will build up
and prevent proper discharge
of air from tumblers.

To reduce the risk of electrical shock,
de-energize the electrical circuit being
connected to the tumbler before making any electrical connections. Never
attempt to connect a live circuit.
NAMEPLATE
Use the following steps to connect electrical service
to the tumbler:
GUARD
1. Install a circuit breaker, as close to tumbler as
possible. If more than one tumbler is being
installed, a circuit breaker should be provided
for each tumbler. This will make it possible to
disconnect each tumbler for maintenance
purposes.

3. Check electrical service phase sequence
(three phase only) as follows:
a. Energize electrical service and momentarily
start tumbler. Check direction of the cylinder
rotation. If cylinder rotates clockwise (viewed
from front), phase sequence is correct. If
cylinder rotates counterclockwise, proceed
with step “b”.
b. Disconnect and reverse any two leads at

POSITIONING DRYING TUMBLER
Screw four leveling legs back into level adjusting
fittings from top. Slide tumbler to its permanent
location and level. Keep tumbler as close to floor as
possible. All four legs must rest firmly on floor so
weight of tumbler is evenly distributed. Tumbler must
not rock.
Tumbler may be removed from skid before moving to
installation location or moved while still attached to
skid. Remove tumbler from skid by unscrewing four
shipping capscrews (one at each corner) and remove
tumbler from skid. Lint panel door will have to be
removed in order to remove two front capscrews.
NOTE: Do not throw these four capscrews away
— they are the leveling legs.
LEVELING DRYING TUMBLER
Each tumbler should be leveled within ¹⁄₈ inch
(3.2 mm) from front to rear, and ¹⁄₈ inch (3.2 mm) from
side to side. Check front to rear level by rotating
clothes cylinder until one rib is at bottom, then place a
level on bottom rib. Side to side level should be
checked by placing a level on front and rear of top
panel.
GAS REQUIREMENTS (Gas Drying Tumblers)
維 WARNING
Size of gas service pipe is dependent upon many
variables (lengths, tees, etc.). Specific pipe size
information should be obtained from gas supplier.
Refer to table in Figure 22 for general pipe size data.
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 room where the tumbler is
installed.
It is important that equal gas pressure be maintained
at all tumbler gas connections. This can best be done
by installing a one inch pipe gas loop as shown in
Figures 20 and 21.
42
M412616
Example of Gas Loop Piping
IMPORTANT: Gas loop piping must be installed
as illustrated to equalize gas pressure for all
tumblers connected to single gas service.
Other gas using appliances should be
connected upstream from loop.

GAS CONNECTIONS (Gas Drying Tumblers)
Before connecting gas piping to tumbler, make
certain gas service is same as that specified on
nameplate (near gas connection), Page 5.
Purge air and sediment from gas service line before
connecting it loosely to tumbler. Purge remaining air
until odor of gas is detected, then tighten connection.
Use pipe compound, resistant to actions of L.P.
gas, on all pipe threads.
NATURAL GAS service must be supplied at 6¹⁄₂ ± 1¹⁄₂
inch water column pressure (1.62 ± .37 kPa).
維 WARNING
Check all pipe connections, internal
and external, for gas leaks using a
soapy solution. To reduce the risk of
explosion or fire, DO NOT USE AN
OPEN FLAME TO CHECK FOR GAS
LEAKS! Gas connections should be
checked annually for leakage.
L.P. GAS service must be supplied at 11 ± .3 inch
water column pressure (2.74 ± .07 kPa).
If gas service is not same as that specified, DO NOT
CONNECT THE GAS LINE TO TUMBLER! It will first
be necessary to convert gas burner orifice and gas
valve.
IMPORTANT: Any product revisions or
conversions must be made by the Manufacturer’s
Authorized Dealers, Distributors or local service
personnel.
維 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 1/2 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 1/2 psig (3.45 kPa).

DRYING TUMBLER ENCLOSURE CONSTRUCTION
維 WARNING
IMPORTANT: DO NOT block airflow at top rear of
tumbler with laundry, etc. Doing so would prevent
adequate air supply to tumbler’s heat chamber.
To reduce the risk of serious injury,
install lockable doors to prevent public
access to rear of tumblers.
A typical tumbler enclosure is shown in Figure 23.
Note that enclosure does touch tumbler top and side

INSTALLING STEAM TRAP AND MAKING
CONDENSATE RETURN CONNECTIONS
Steam trap must be installed and coil outlet
connections must be connected to condensate return
lines. The following steps outline the procedure for
installing steam trap and connecting condensate
return lines. See Figure 24 for a typical installation.
High pressure machines require a (constant) 80 to
100 psig (5.62 to 7.03 kg/sq. cm) steam service for
optimum operation. Low pressure machines require a
(constant) 10 to 15 psig (.70 to 1.05 kg/sq. cm) steam
service for optimum operation. The following steps
outline procedure for installing steam solenoid valve
and connecting steam service.
a. Connect a flexible hose to each steam coil outlet,
Figure 24.
b. Install a strainer to the ends of each flexible hose.
c. Install a steam trap to each strainer.
a. Install a manual shut-off gate valve in condensate
return line after steam trap for each coil.
IMPORTANT: Steam trap must be installed a
minimum of 10 inches (25.4 cm) below steam coil
outlet connections, see Figure 24.
b. Connect steam solenoid valve to related steam
coil inlet connection with nipples, flex hoses,
unions, tee and pressure relief valve. See Figure
24 for a typical installation.
d. Install a gate shut-off valve to each steam trap.
e. Connect to condensate return lines.
c. Install a gate shut-off valve in steam supply
line, Figure 24. Connect shut-off gate valve
outlet to solenoid steam valve inlet connection.
aWARNING
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
shutoff gate valve must be installed
downstream from each steam trap so
the condensate return line can be
isolated in event a steam trap requires
maintenance.
aWARNING
The flexible steam hoses connecting
the solenoid steam valve to the coil
inlets must have a 125 psig (pounds
per square inch gauge) (8.79 kg/sq.
cm) working pressure. A shut-off gate
valve must be installed upstream from
the solenoid steam valve. This way,
steam can be shut off for maintenance
purposes, or in the event the hose
ruptures.
Each steam trap must be supported so
minimum load is exerted on the coil
outlet connection.

Adjustments
MAIN GAS BURNER AIR SHUTTER
(All Gas Models)
5. After air shutter is adjusted for proper flame,
tighten air shutter adjusting screw securely.
Control panel may have to be removed
temporarily to loosen air shutter screws to turn
shutter.
NOTICE: Both air inlet shutters on burner must
be adjusted so sufficient air is metered into
system for proper combustion and maximum
efficiency. Before adjusting inlet shutters be sure
that all lint is removed from lint compartment and
lint screen.
6. If shutter is correctly adjusted, but flame pattern is
straight up, (Figure 29), insufficient primary air is
flowing through tumbler and airflow switch is
improperly set. A flame pattern that flares to right
and left (Figure 29) indicates no air is flowing
through tumbler.
Air shutter adjustments will vary from location to
location and will depend on vent system, number of
units installed, make-up air and line gas pressure.
Opening shutter increases amount of primary air
supplied to burner while closing shutter decreases
primary air supply. Adjust air shutter as follows:
AIR FLOW SWITCH
(Gas and Electric Models, see Figure 30)
Air flow switch is set at factory for proper operation.
Steam models do not have an air flow switch.
However, if there is a problem with airflow switch, it
should be adjusted as follows:
1. Unlock and open access door.
2. Start tumbler and check flame pattern. Correct air
and gas mixture is indicated if flame pattern is
primarily blue, with small yellow tips, and bends to
right of heater section. (See Figure 29.) Too little
air is indicated if flame is yellow, lazy and smokey.
NOTICE: Control panel must be in place and
access door closed before attempting to adjust
air flow switch.
3. To adjust air shutter, loosen air inlet shutter
adjusting screw, see Figure 29.
IMPORTANT: Air flow switch disc must remain
closed during operation. If it opens and closes
during drying cycle, this indicates insufficient air
flow through tumbler.
4. Open or close air shutter as necessary to obtain
proper flame intensity.

Electric Models: If switch remains open, or pops
open and closed during cycle, heating system will
shut off. Cylinder and fan will continue to operate
even though air flow switch is malfunctioning.
Counterweight should be adjusted so air flow will
force disc away from cabinet when lint panel is
opened 6 inches (15.24 cm) with a full load. Adjust air
flow switch as follows:
1. Load tumbler.
Gas Models: If switch remains open, entire unit
will shut down when Push-to-start button is
released. Once tumbler starts and continues to
run, a loss of air flow, air flow switch jams or a
bouncing air flow switch will shut entire tumbler
down.
NOTE: This adjustment is much faster to make
with one person opening lint panel in front and
another adjusting the counterweight in rear of
tumbler.
2. Start tumbler. Open lint panel 6 inches (15.24 cm).
Airflow disc should move away from cabinet,
opening switch contacts and shutting off heat
system. This indicates proper operation and
proper adjustment.
維 WARNING
To reduce the risk of fire, air flow
switch operation may be affected by a
clogged lint screen, lack of make-up
air, obstructions in the vertical
recirculation stack or in the customer
installed main or collector ducts.
These conditions must be checked
and necessary corrections made
before adjusting air flow switch.
Always adjust air flow at installation.
3. If switch is not opening as described in step “2”, it
should be adjusted so it is MORE sensitive.
Depress 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
proper distance, step “2”, it should be adjusted so
it is LESS sensitive. Depress spring clip and move
counterweight away from disc. Retest by opening
lint panel and continue moving counterweight
away from disc until switch operates as described
in step “2”.
Air flow switch operation is controlled by counterweight position on shaft. Moving counterweight either
increases or decreases air flow switch sensitivity.
