WARNING: Purchaser must post the following notice in a prominent location:
FOR YOUR SAFETY
Do not store or use gasoline or other flammable vapors
and liquids in the vicinity of this or any other appliance.
WARNING: A clothes dryer produces combustible lint and should be exhausted outside the
building. The dryer and the area around the dryer should be kept free of lint.
WARNING: Be safe, before servicing machine, the main power should be shut off.
Page 2
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 Manufacturer’s 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.

UNPACKING
Unpacking/General Installation (All Dryers)
Upon arrival of the equipment, any damage in shipment should be
reported to the carrier immediately.
Upon locating permanent location of a unit, care should be taken in
movement and placement of equipment.
See outline clearance diagrams for correct dimensions.
Remove all packing material such as: tape, manuals, skid, etc
Leveling: Use spirit level on top of dryer. Adjust leveling bolts on
dryer (see adjustable leveling bolts in maintenance section).
Check voltage and amperes on rating plate before installing the dryer.
GENERAL
INSTALLATION (ALL
DRYERS)
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.
Page 9
Unpacking/General Installation (All Dryers)
GENERAL
INFORMATION
The dryer is so designed that when an operator opens the dryer
door, the basket and exhaust fan stop. 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 selfcleaning lint screen. In this system, lint accumulates on the
underside of the screen until a 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.
IMPORTANT
Provide adequate clearance for air openings into the combustion
chamber.
DRYER
“COOL-DOWN”
CYCLE
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.
REPLACEMENT
PARTS
Replacement parts for this dryer are available from your distributor
or by contracting the factory at the address or phone number printed
on the cover page of this manual.
ONLY CISSELL PARTS SHOULD BE USED.

Electrical Connections - All Dryers
ELECTRICAL
CONNECTIONS
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. In all cases, the 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.
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 the 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.)
All panels must be in position before operation of dryer.
ELECTRICAL
CONTROLS SERVICE
Caution: Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and dangerous operation.
Verify proper operation after servicing.

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 water column maximum. Manifold
pressure—3.5 inches water column (8.8 mbar) pressure.
6. L.P. gas only—check the gas pressure inlet supply to dryer,
13 inches water column(32.4 mbar) maximum. Manifold
pressure—11 inches water column (27.4 mbar) pressure.
CAUTION: Low gas pressure and intermittent gas will cause
gas ignition problems and inadequate drying of laundry.

Gas Piping Installation (Illustrations)
Gas shutoff valve is not supplied with dryer.
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).

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.

REGULATOR FOR
LIQUIFIED
PETROLEUM GASES
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 PIPINGINSTALLATION
INSTRUCTIONS
PIPING
RECOMMENDATIONS
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 improperly drained
steam header will provide wet steam, causing improper operation of dryer.
If pockets or improper drainage cannot be eliminated, install a bypass trap
to drain condensate from the low point in the steam supply header to the
return.
4.
In both steam supply and steam return line, it is recommended that each
have a 3/4" 20 mm) union and 3/4" (20 mm) 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.
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 beyond dryer. Install globe valve, union, check valve and bypass trap at
end of line. If gravity returned 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.

Page 28
Exhaust and Venting
DRYER AIR FLOW
INSTALLATION
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” w.c.
(.8 mbar) 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.
EXHAUST DUCT
FOR BEST DRYING:
1. Exhaust duct maximum length 14 feet (5 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” water column (.8 mbar) 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
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 m2)
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
Other Recommendations
To assure compliance, consult local building code requirements.
TROUBLESHOOTING
Troubleshooting
Hot dryer surfaces, scorched clothes, slow drying, lint accumulations, or air

4.
5.
6.
Be sure your dryer is installed properly in accordance with the
recommended instructions.
CAUTION
Be safe—shut main electrical power supply and gas supply off
externally before attempting service.
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.
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.
Never use dryer door opening and top as a step stool.
Read and follow manufacturer’s instructions on packages of laundry and
cleaning aids. Heed any warnings or precautions.
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.
Reference: Lighting and shut-down instructions and wiring diagrams
are located on the rear wall of the dryer cabinet.
The dryer must not be installed or stored in an area where it will be
exposed to water and/or weather.
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.
Operate dryer using full-size loads. Very large loads use extra energy.
Very small loads waste energy.
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.
Clean the lint screen area daily. A clean lint screen helps give faster,
more economical drying.
Do not open the dryer door while drying. You let warm air escape from
the dryer into the room.
Unload the dryer as soon as it stops. This saves having to re-start your
dryer to remove wrinkles.

This dryer is designed for a capacity maximum load. Overloading
it will result in longer drying time and damp spots on some of the
load.
Maximum operating efficiency depends on proper air flow. The

Direct-Spark Ignition Operation
DIRECT SPARK
IGNITION
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.

GENERAL
MAINTENANCE
(continued)
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 burner 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.
