WARNING: To avoid fire hazard, do not dry articles containing foam rubber or similar texture materials.

Do not put into this dryer flammable items such as baby bed mattresses, throw rugs,undergarments
(brassieres, etc.) and other items which use rubber as padding or backing. Rubber easily oxidizes causing
excessive heat and possible fire. These items should be air dried.

WARNING: Synthetic solvent fumes from drycleaning machines create acids when drawn through the
dryer. These fumes cause rusting of painted parts, pitting of bright or plated parts, and completely
removes the zinc from galvanized parts, such as the tumbler basket. If drycleaning machines are in the
same area as the tumbler, the tumbler's make-up air must come from a source free of solvent fumes.

WARNING: Do not operate without guards in place.

WARNING: Check the lint trap often and clean as needed but at least a minimum of once per day.

WARNING: Alterations to equipment may not be carried out without consulting with the factory and
only by a qualified engineer or technician. Only Manufacturers parts may be used.

WARNING: Remove clothes from dryer as soon as it stops. This keeps wrinkles from setting in and

reduces the possibility of spontaneous combustion.

WARNING: Be safe - shut main electrical power and gas supply off externally before attempting
service.

WARNING: Never use drycleaning solvents, gasoline, kerosene, or other flammable liquids in the dryer.

FIRE AND EXPLOSION WILL OCCUR. NEVER PUT FABRICS TREATED WITH THESE LIQUIDS
INTO THE DRYER. NEVER USE THESE LIQUIDS NEAR THE DRYER..

WARNING: Do not place items exposed to cooking oils in your dryer. Items contaminated
with cooking oils may contribute to a chemical reaction that could cause a load to catch fire.

WARNING: Never let children play near or operate the dryer. Serious injury could occur if a child
should crawl inside and the dryer is turned on.

WARNING: Never tumble fiberglass materials in the dryer unless the labels say they are machine
dryable. Glass fibers break and can remain in the dryer. These fibers cause skin irritation if they
become mixed with other fabrics.

WARNING: Before operating gas ignition system - purge air from natural gas or propane gas lines
per manufacturer’s instructions.

WARNING: To reduce the risk of electric shock, disconnect this appliance from the power supply
before attempting any user maintenance other than cleaning the lint trap. Turning the controls to the
OFF position does not disconnect this appliance from the power supply.

The construction of the dryers permits installation side-by-side to

save space or to provide a wall arrangement. Position dryer for the
least amount of exhaust piping and elbows, and allow free access to
the rear of dryer for future servicing of belts, pulleys and motors.
Installation clearance from all combustable material is 0" ceiling
clearance, 0" rear clearance, and 0" side clearance.

Before operating dryer, open basket door and remove blocking
between front panel and basket. Read the instruction tags, owner's
manual, warnings, etc.

IMPORTANT
Opening the clothes loading door deactivates the door switch
to shut off the motors, fan, gas, steam, or electric element. To
restart the dryer, close the door and press in the push to start
button and hold briefly.

IMPORTANT
This dryer is designed for a capacity maximum load.
Overloading it will result in long drying times and damp spots
on some clothes.

IMPORTANT
Maximum operating efficiency is dependent upon proper air
circulation. The lint screen must be kept cleaned daily to
insure proper air circulation throughout the dryer.

IMPORTANT
Provide adequate clearance for air opening into the combustion
chamber.

General Information

GENERAL
INFORMATION

DRYER
COOL-DOWN

The dryer is so designed that when an operator opens the dryer door,
the basket and exhaust fan stops. You can expect fast drying from a
laundry dryer. Hot, dry air is properly and effectively moved through
the basket and exhausted through a lint trap to the atmosphere. The
dryer comes equipped with an inclined, self-cleaning lint screen. In
this system, lint accumulates on the underside of the screen until a
blanket approximately 1/4” (6 mm) thick is formed. This blanket of
lint will fall from the screen to the bottom of the dryer cabinet and
should be removed daily, or as required, to prevent an over
accumulation.

Permanent press, durable press and other modern day fabrics require
the care that your laundry dryers now provide.

At the end of the drying cycle, a timed “cool-down” control
automatically takes over and continues the rotation of the fan and
basket without heat until the garment load reaches a safe cool
temperature. This function is performed at the end of each drying
cycle and continues for two minutes.
Dryers must be electrically grounded by a separate #14 or larger
green wire from the grounding terminal within the service connection
box to a cold water pipe, or through the fourth green wire properly
grounded and connected to the grounding terminal. In all cases, the

Page 15

ELECTRICAL
CONNECTIONS

Grounding Instructions (Illustration)

grounding method must comply with local electrical code
requirements; or in the absence of local codes, with the National

Electrical Code, ANSI/NFPA 70 or the Canadian Electrical Code,
CA C22.1.

ELECTRICAL
CONTROLS SERVICING

See wiring diagram furnished with dryer. Your dryer is completely
wired at the factory and it is only necessary for the electrician to
connect the power leads to the wire connectors within the service
connection box on the rear of the dryer. Do not change wiring
without consulting factory as you may void the factory warranty. Do
not connect the dryer to any voltage or current other than that
specified on the dryer rating plate. (Wiring diagram is located on
rear wall of dryer.)

Caution: Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and dangerous operation.

Verify proper operation after servicing.

Attention. Lors des operations d’entretien des commandes,
etiqueter tous les fils avant de les deconnecter. Toute erreur
de cablage peut etre une source de danger et de panne.

Page 16

Piping Recommendations

PIPING
RECOMMENDATIONS

1. Trap each dryer individually. Always keep the trap clean
and in good working condition.

2. When dryer is on the end of a line of equipment, extend
header at least 4 feet (1.22 m) beyond dryer. Install globe
valve, union, check valve and by-pass trap at end of line. If
gravity return to boiler, omit trap.

3. Insulate steam supply and return line for safety of operator
and safety while servicing dryer.

4. Keep dryer in good working condition. Repair or replace any
worn or defective parts.

STEAM HEATING
UNITS

1. Keep steam coils clean.

2. Check periodically and clean as often as required.

3. Remove lint and dirt accumulation from coil fins periodically
as dirty lint-laden coil fins decrease the efficiency of steam­heated dryers.

Page 17

Gas Piping Installation

GAS PIPING
INSTALLATION

1. The installation must conform with local codes, or in the

absence of local codes with the National Fuel Gas Code,

ANSI Z223.1 or the CAN/CGA-B149, Installation Codes.

2. Check identification nameplate for type of gas for dryer.

3. Check the altitude of dryer.

4. Check with utilities company for proper gas pressure and gas
supply line.

5. Natural gas only—check the gas pressure inlet supply to
dryer, 11 inches (27 mbar) water column maximum. Manifold
pressure—3.5 inches (8.7 mbar) water column pressure.

6. L.P. gas only—manifold pressure—13 inches (32 mbar)
water column maximum.

CAUTION: Low gas pressure and intermittent gas will cause
gas ignition problems and inadequate drying of laundry.

Page 18

Gas Piping Installation (Illustration)

The dryer and it’s individual shutoff 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 (3.5 kPa).

The dryer must be isolated from the gas supply piping system by closing it's individual manual shutoff
valve during any pressure testing of the gas supply piping system at test pressures equal to or less
than 1/2 psi (3.5 kPa).

Page 19

Gas Service Installation Instructions

GAS SERVICE
INSTALLATION
INSTRUCTIONS

The size of the gas service pipe is dependant upon many variables,
such as tees, lengths, etc. Specific pipe size should be obtained from
the gas supplier. Refer to the “Gas Pipe Size” chart in this manual for
general gas pipe size information.

CAUTION: Gas loop piping must be installed as illustrated
to maintain equal gas pressure for all dryers connected to a
single gas service

Other gas-using appliances should be connected upstream
from the loop.

GAS PRESSURE
REGULATOR FOR
LIQUIFIED
PETROLEUM GASES

WARNING:
LIQUIFIED PETROLEUM GASES ONLY !

A gas pressure regulator for liquified petroleum gases is not
furnished on gas heated clothes dryers. This regulator is normally
furnished by the installer. In accordance with American Gas
Association (AGA) standards, a gas pressure regulator, when
installed indoors, must be equipped with a vent limiter or a vent line
must be installed from the gas pressure regulator vent to the outdoors.

Steam Piping Installation Instructions

STEAM PIPING
INSTALLATION
INSTRUCTIONS

1. Set and anchor dryer in position. Machine should be level to
assure proper steam circulation.

2. To prevent condensate draining from headers to dryer, piping
should have a minimum 12" (305 mm) above respective
header. Do not make steam connection to header with a
horizontal or downwardly facing tee or elbow.

3. Whenever possible, horizontal runs of steam lines must drain,
by gravity, to respective steam header. Water pockets, or an
imporperly drained steam header will provide wet steam,
causing improper operation of dryer. If pockets or improper
drainage cannot be eliminated, install a by-pass trap to drain
condensate from the low point in the steam supply header to
the return.

4. In both steam supply and steam retyrn line, it is recommended
that each have a 3/4" (DN 20) union and 3/4" (DN 20) globe
valve. This will enable you to disconnect the steam
connections and service the dryer while your plant is in
operation.

5. Before connecting trap and check valve to dryer, open globe
valve in steam supply line and allow steam to flow through
dryer to flush out any dirt and scale from dryer. This will
assure proper operation of trap when connected.

6. After flushing system, install bucket trap (with built-in
strainer) and check valve. For successful operation of dryer,
install trap 18" (457 mm) below coil and as near to the 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 check valve in return line near dryer.

7. Install union and globe valve in return line and make final
pipe connections to return header.

Dryer InstallationWith Multiple Exhaust

DRYER INSTALLATION
WITH MULTIPLE EXHAUST

For Exhaust Duct more than 14 feet (5 m) and 2 elbows equivalent and
more than 0.3 inches (8 mm) water column static pressure.

(See illustration on next page.)

1. Make-up air from outside building may enter enclosure from top or
side walls. (See Dryer Make-up Air Requirements Chart)

2. Use constant diameter duct with area equal to the sum of dryer duct
areas.
EXAMPLE: 6-8 inches (203 mm) diameter duct = 1-19.6 inches
(498 mm) diameter duct in area. Use 20 inches (508 mm) diameter
duct or diameter to match tube-axial fan.

3. Enclosure (plenum) with service door. This separates the dryer air from
room comfort air. If dryers use room air instead of outside air, the heat
loss can be another 25 Btu/h (6.3 kcal/h) for each cubic foot per minute
(cfm) used.

4. Zero inches clearance to combustible material allowed on sides and at
points within 4 inches (100 mm) of front on top.

5. Heat loss into laundry room from dryer fronts only is about 60 Btu/h
per square foot (15 kcal/h per 0.1m²).

6. Flange mounted, belt driven tube-axial fan. Fan must run when one or
more dryers are running. See suggested Automatic Electrical Control
Wiring Diagram on previous page. Must meet local electrical codes.
Fan air flow (cfm) (m³/h.) is equal to sum of dryer air flows, but static
pressure (SP) is dependent on length of pipe and number of elbows.

7. Barometric bypass damper—Adjust to closed flutter position with all
dryers and exhaust fan running. Must be located within enclosure.

CAUTION: Never install hot water heaters or other gas appliances
in the same room as dryers. Never install cooling exhaust fans in the
same room as dryers.

CAUTION: Never exhaust dryers with other types of equipment.

Exhaust and Venting

DRYER AIR FLOW
INSTALLATION

EXHAUST
DUCT

Nothing is more important than air flow for the proper operation of a clothes
dryer. A dryer is a pump which draws make-up air from the out-of-doors,
through the heater, through the clothes and then forces the air through the
exhaust duct back to the out-of-doors. Just as in a fluid water pump, there must
be a fluid air flow to the inlet of the dryer, if there is to be the proper fluid air
flow out of the exhaust duct.
In summary, there must be the proper size out-of-doors inlet air opening 4-6
times the combined areas of the air outlet) and an exhaust duct, size and length
of which allows flow through the dryer with no more than 0.3 inches (7.6 mm)
water column static pressure in the exhaust duct.
In some instances, special fans are required to supply make-up air, and/or boost
exhaust fans are required for both regular and energy saving models.

FOR BEST DRYING:

1. Exhaust duct maximum length 14 feet (4.3 m) of straight duct and

maximum of two 90° bends.

2. Use 45° and 30° elbows wherever possible.

3. Exhaust each dryer separately.

4. Use 2 feet (0.6 m) of straight duct on dryer before installing an elbow

on Energy-Saver models only.

5. Do not install wire mesh or other restrictions in the exhaust duct.

6. Use clean-outs in the exhaust duct and clean periodically when needed.

7. Never exceed 0.3 inches (7.6 mm) water column static pressure in the

exhaust duct.

8. Inside surface of the duct must be smooth.

9. Recommend pop rivets for duct assembly.

MAKE-UP AIR

OTHER
RECOMMENDATIONS

TROUBLESHOOTING

FOR BEST DRYING:

1. Provide opening to the out-of-doors in accordance with the following:

For each dryer—
6 inches (152 mm) diameter exhaust requires a 1 square feet (0.1 m²)
opening for make-up air.
8 inches (203 mm) diameter exhaust requires a 2 square feet (0.2 m

2

opening for make-up air.
12 inches (305 mm) diameter exhaust requires a 4 square feet (0.4 m2)
opening for make-up air.

2. Use barometric shutters in the inlet air opening to control air when

dryers are not running.

Other Recommendations

To assure compliance, consult local building code requirements.

Troubleshooting

Hot dryer surfaces, scorched clothes, slow drying, lint accumulations, or air
switch malfunction are indicators of exhaust duct and/or make-up air problems.

Rules for Safe Operation of Dryer

RULES FOR SAFE
OPERATION OF DRYER

1. Be sure your dryer is installed properly in accordance with the
recommended instructions.

2. CAUTION
Be safe—shut main electrical power supply and gas supply off
externally before attempting service.

3. CAUTION
Never use drycleaning solvents: gasoline, kerosene, or other flammable
liquids in the dryer. Fire and explosion will occur.

Never put fabrics treated with these liquids into the dryer.
Never use these liquids near the dryer.
Always keep the lint screen clean.
Never use heat to dry items that contain plastic, foam or sponge rubber,

or rags coated with oils, waxes or paints. The heat may damage the
material or create a fire hazard. Rubber easily oxidizes, causing
excessive heat and possible fire.
Never dry the above items in the dryer.

4. Never let children play near or operate the dryer. Serious injury will
occur if a child should crawl inside and the dryer is turned on.

5. Never use dryer door opening and top as a step stool.

6. Read and follow manufacturer’s instructions on packages of laundry and
cleaning aids. Heed any warnings or precautions.

7. Never tumble fiberglass materials in the dryer unless the labels say
they are machine dryable. Glass fibers break and can remain in the dryer
and could cause skin irritation if they become mixed into other fabrics.

8. Reference: Lighting and shut-down instructions and wiring diagrams
are located on the rear wall of the dryer cabinet.

9. The dryer must not be installed or stored in an area where it will be
exposed to water and/or weather.

ENERGY-SAVING TIPS

1. Install dryer so that you can use short, straight venting. Turned elbows
and long vent tubing tend to increase drying time. Longer drying time
means the use of more energy and higher operating costs.

2. Operate dryer using full-size loads. Very large loads use extra energy.
Very small loads waste energy.

3. Dry light-weight fabrics separately from heavy fabrics. You will use
less energy and get more even drying results by drying fabrics of
similar weight together.

4. Clean the lint screen area daily. A clean lint screen helps give faster,
more economical drying.

5. Do not open the dryer door while drying. You let warm air escape from
the dryer into the room.

6. Unload the dryer as soon as it stops. This saves having to re-start your
dryer to remove wrinkles.

OPERATION

NOTE: Some models are equipped with a dual ignition system.

The dual ignition system contains two direct spark
ignition modules in parallel. Each module has its own
flame sense circuit and acts independently of the other.
If either bonnet limit thermostat opens because of high
heat or flame impingement, the entire ignition system
will shut down.

1. When a call for heat is received from the control supplying
24VAC to the ignition control module, the pre-purge delay
timer begins. This delay time allows any air/sediment to be
ejected prior to burner ignition. Following the pre-purge delay
period, the gas valve is energized and the spark ignitor sparks
for the trial ignition period.

2. When a flame is detected during the trial for ignition period, the
spark ignitor shuts off and the gas valve remains energized.

3. If no flame is detected by the flame sense circuit, the ignition
control module will go into safety lockout. The valve will be
turned off immediately. If the module has multiple retries and
no flame is detected, the gas valve is de-energized and the
module goes into an interpurge delay. After this delay, the
module will attempt another trial for the ignition period. This
will continue until the number of retries has been used up. At
the time, the module will go into safety lockout.

4. Recovery from safety lockout requires one of the following:
a. A manual reset by opening and closing the loading door.
b. After one hour if the control thermostat is still calling for

heat, the module will automatically reset and the trial for
ignition period will start over.

5. Opening the loading door will cause the flame to extinguish.
Closing the door and starting the dryer will restart the trial for
ignition period.

6. Once the control thermostat has been satisfied and/or the
drying timer has been timed out, the ignition control
module(s) will be de-energized, the gas valve(s) will be de­energized and the flames will extinguish.

7. The machine will continue to run in a cooldown mode without
heat. This process will cool the load to the touch and help to
eliminate wrinkling.

General Maintenance

GENERAL
MAINTENANCE

1. Clean lint trap daily. Remove lint before or after each day of

operation. A clean lint trap will increase the efficiency of the
dryer and the moisture-laden air will be exhausted outside
more quickly.

2. Keep basket and sweep sheets clean. Clean as often as

needed. The basket and sweep sheets are accessible by
removing the front panel of the dryer.

3. Gas burners, steam coils, electric coils. Check and clean

often.

4. Pulleys and belts. Keep clean as oil and dirt will shorten the

life of a belt. Check periodically for alignment. Pulley shafts
must be parallel and the grooves must be aligned. Check belt
tension periodically. Adjust tension by movement of idler
bracket. Lubricate idler pulley once every two months using
six grams of high temperature grease. Do not over-grease.

5. Electric motor. Keep motor clean and dry. Motors are

packed with sufficient grease for 10 years normal service.
After that, bearings and housing should be cleaned and
repacked one third full with Chevron grease No. SR1-2. See
label on motor for further information.

If motor overheats, check voltage and wiring. Low voltage,
inadequate wiring and loose connections are the main cause
of motor failures.

6. Adjustable leveling bolts. One at each corner permits

accurate alignment of dryer.
To adjust: Block one corner of dryer up off the floor, loosen
hex nut. With wrench, turn bolt clockwise to raise dryer,
opposite to lower. Rear bolts are outside of dryer and front
bolts are inside lint trap compartment.

MAINTENANCE

7. Periodically clean and examine exhaust system.

8. Keep dryer area clean and free of gasoline, combustible
materials and other flammable liquids or vapors.

9. Do not obstruct the flow of combustion (make-up) air and
ventilating air.

10. Check gas pressure periodically.

11. Gas burners air inlet shutters can be adjusted for proper flame
by following instructions outlined on separate page of this
manual.

12. Main Basket Bearings. Lubricate once every six months
using six grams of high temperature grease. Do not over­grease.

13. Steam Heating Units. Keep steam coils clean. Check
periodically and clean as often as required. Remove lint and
dirt accumulation from coil fins to avoid decreasing their
efficiency.

14. Clean Out Panel (Energy Saver Gas Models Only). Remove
this panel located on the energy saver heating unit and clean
the inside area of lint and dirt on a regular basis.

TYPE OF GAS SHUTTER ADJUSTMENT

Natural gas 1/2 Open
Liquid petroleum 1/4 Open
Manufactured gas 1/16 Open

AIR SHUTTER ADJUSTMENT:

Proper Method

Close air shutters to yellow tip, then open air shutters to blue flame
tip. Orange tips are impurities in the air such as lint, dust, etc.

ADJUSTMENT

Burner air inlet shutters are adjusted closed. Insufficient air is
admitted through the burner. Flame pattern is straight up and flame
is yellow.

WRONG—NEED TO ADJUST SHUTTER

BURNER AIR INLET
SHUTTER ADJUSTMENT

This flame pattern indicates the burner air inlet shutters are correctly
adjusted, but air through the dryer is insufficient. This condition
indicates excessive lint in the lint compartment, lack of make-up air
in the room, restricted exhaust duct, or a vacuum in the room caused
by an exhaust fan.

Basket Shimming Instructions

BASKET SHIMMING
INSTRUCTIONS

This procedure is normally necessary when replacing either the
basket or the spider assembly on any dryer. Proper shimming is
crucial to obtain a true running basket.

A. Align the basket as per instructions in the manual.
B. Rotate the basket to determine where the most out-of-round

point is (where the basket scrapes or comes closest to
scraping the sweep sheet).

C. Mark this position and the nearest rib to this position.
D. Remove the basket (do not loosen the alignment bolts).
E. With the basket on the floor (spider up), place one or two

shims between the spider leg and the back of the basket at the
marked rib position. (See drawing.)

F. Re-insert spider and basket assembly and re-check cylinder.
G. If at this point, basket is still out-of-round, procedure must be

repeated starting with Step “B”.

H. Upon completion of shimming process, realignment of basket

is necessary.

NOTE
If the point mentioned in Step “B” is between two ribs, both
ribs might have to be shimmed.
