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 Manufacture’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/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.
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.
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
INSTALLATION
(ALL DRYERS)
Page 9
Unpacking/General Installation (All Dryers)
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 the 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 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.
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.
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.

The gas supply pipe should be connected to the gas tap (I), which is on the right next
to the wiring box on the back.
It is very important to have the connections done by a qualified technician, in order
to make sure that the installation is effected in accordance with the prevailing
standards and instructions.
The dryer should be connected to the type of gas, which is indicated on the serial plate.
The use of too small gas pipes can result in unsufficient gas supply, which can lead
to a bad heating-up and a poor drying quality.
When the dryer is used in combination with a weighing platform, the gas supply pipe
has to be made of flexible material to allow the weighing system to keep moving
freely.
I
It is important to work with the right gas pressure (see technical remarks) in order to
obtain a good ignition, heating and consequently a good operation in general.
After the gas supply has been connected, the gas tap in the dryer should beturned on
(clockwise).
Test all connections for possible leaks by means of a soap solution, but
never with a flame.

Gas Piping Installation
1. The installation must conform with local codes, or in
the absence of local codes with the National Fuel
Gas Code as, 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” water column (27.4 mbar)
maximum. Manifold pressure—3.5” water column
(8.8 mbar) pressure .
6. L.P. gas only—manifold pressure—13” water
column (32.4 mbar) maximum.
CAUTION: Low gas pressure and intermittent
gas will cause gas ignition problems and
inadequate drying of laundry.

INSTALLATION
Page 15
Gas Piping Installation (Illustrations)
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 (.04 bar).
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 (.04 bar).
Page 16
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.
WARNING:
LIQUIFIED PETROLEUM GASES ONLY !
A gas pressure regulator for liquified petroleum gases is
not furnished on the 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.

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) static pressure.
(See illustration on page 21.)
1. Make-up air from outside building may enter enclosure from top
or side walls. (See Dryer Make-Up Air Chart)
2. Use constant diameter duct with area equal to the sum of dryer
duct areas.
EXAMPLE: Six 8 inch (204 mm)) diameter duct = one
19.6 inch (498 mm) diameter duct in area. Use 20 inch (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 (102 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/min.) 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.

Page 21
Dryer Installation With Separate Exhaust (Preferred)
For ductwork less than 14 feet (5 m) and 2 elbows equivalent
and less than 0.3 inches (8 mm) static pressure:
NEVER exhaust the dryer into a chimney.
NEVER install wire mesh screen over the exhaust or
make-up air area.
NEVER exhaust into a wall, ceiling, or concealed space.
1. Make-up air opening from outside the building may enter the
enclosure from the top or side walls. (See Dryer Make-Up Air
Chart)
2. Enclosure (plenum) with service door. This separates the
dryer air from the room comfort air. If dryers use room air
instead of outside air, additional heat loss can be another
25 Btu/h (6.3 kcal/h) for each cubic foot per minute (cfm)
(.03m³/min.) used.
3. Zero inches (mm) clearance to combustible material allowed on
sides and at points within 4 inches (102 mm) of front on top.
4. Heat loss into laundry room from dryer front panels is about
60 Btu/h per square foot (15 kcal/h per 0.1m²).
DRYER INSTALLATION

EXHAUST (PREFERRED)
Page 22
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 water column (.8 mbar) 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 (5 mm) 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 (0.7 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 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.
FOR BEST DRYING:
1. Provide opening to the out-of-doors in accordance with the
following:
For each dryer—
6 inches (2 m) diameter exhaust requires a 1 square feet
(0.1 m²) opening for make-up air.
8 inches (3 mm) diameter exhaust requires a 2 square feet
(0.2 m²)opening for make-up air.
12 inches (4 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
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.
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.
Page 24
NOTE: All dryers manufactured are equipped with the DSI
(direct spark ignition) modules. These are designed to increase
dryer efficiency and to reduce dryer operating costs. The main
burner is directly ignited from a spark electrode. A burning flame
provides an electrical path for a small amount of sensing current to
allow gas valve operation. If the main burner flame extinguishes for
any reason (aside from the thermostatic control) sensing current
will shut down the gas valve and the spark ignition circuit.
1. Once flame is established, the spark shuts off, and the main
burner flame is then electronically monitored by means of a
sensing spark probe which is located over the burner. The gas
valve remains energized (open).
2. If no flame is detected within the first 11 seconds the DSI will
go into a safety “lock-out”. The gas valve is de-energized.
3. Recovery from a safety lockout requires one of the following:
A. Opening the main door thus interrupting power to the DSI
module and allowing dryer diagnostic trouble shooting.
B. Disconnecting the entire dryer from a power source using a
circuit breaker or a switch.
4. By closing the main door the ignition circuit will be restored for
another trial of the ignition circuit.
5. Once the thermostatic control has been satisfied by reaching a
pre-set temperature or the drying timer has been timed out, the
ignition circuit will be de-energized thus extinguishing the
flames.
6. The dryer will continue to run in a cool-down mode without
heat. This process will cool the load to the touch and help to
eliminate wrinkling.
7. The cool - down time is pre-set on some models and manually set
on other dryer models. The cool-down cycle prevents fabric
wrinkles by allowing clothes to reach room ambient temperature
while still in a continuous levitation state until clothes are ready
to be folded or pressed.

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.
Page 27
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.
