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 permit 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. The
installation clearance from all combustable material is 0" ceiling
clearance for the first 4" (102 mm)from the front of the dryer. After
the first 4" (102 mm), the ceiling clearance required is 6" (153 mm).
The rear clearance required is 0", and the side clearance is 1"
(26 mm).
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 clean daily to ensure
proper air circulation throughout the dryer.
IMPORTANT
Provide adequate clearance for air opening into the combustion
chamber.

Unpacking/General Installation (All Dryers)
GENERAL
INFORMATION
DRYER
“COOL-DOWN”
CYCLE
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.
Permanent press, durable press and other modern day
fabrics require the care that your 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
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.

Gas connection
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 important to have the connections done by a qualified technician, in order to
ensure that the installation is in accordance with the prevailing standards and
instructions.
The dryer should be connected to the type of gas indicated on the serial plate.
The use of too small gas pipes can result in insufficient gas supply, which can lead
to slow heat-up and poor drying quality.
I
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.
Test all connections for possible leaks by means of a soap solution, but
never with a flame.
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 be turned on
(clockwise).
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.

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.
For exhaust duct more than 14 feet (5 m) and 2 elbows equivalent and more
than 0.3 inches (8 mm) static pressure.
1.Make-up air from outside the 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: Six 8 inch (204 mm) diameter ducts = 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/hr (6.3 kcal/hr) for each cubic foot per minute
(cfm) used.
4.The installation clearance from all combustible material is 0" ceiling
clearance for the first 4" (102 mm) from the front of the dryer. After the
first 4" (102 mm), the ceiling clearance required is 6" (153 mm). the rear
clearance required is 0", and the side clearance is 1" (26 mm).
5.Heat loss into laundry room from dryer fronts only is about 60 Btu/hr per
square foot (15 kcal/hr 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 WiringDiagram on previous page. Must meet local electrical codes. Fan air
flow (cfm or m³/min.) is equal to the 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.

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 from outside the building may enter the enclosure from
the top or side walls. (See Dryer Make-Up Air Requirements 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/hr (6.3 kcal/hr) for each
cubic foot per minute (cfm) (.03m³/min.) used.
3.The installation clearance from all combustible material is 0" ceiling
clearance for the first 4" (102 mm) from the front of the dryer. After
the first 4" (102 mm), the ceiling clearance required is 6" (153 mm).

Exhaust and Venting
DRYER AIR FLOW
INSTALLATION
EXHAUST DUCT
MAKE-UP AIR
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 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
booster exhaust fans are required.
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.Do not install wire mesh or other restrictions in the exhaust duct.
5.Use clean-outs in the exhaust duct and clean periodically when needed.
6.Never exceed 0.3 inches (.8 mbar) water column static pressure in the
exhaust duct.
7.Inside surface of the duct must be smooth.
8.Recommend pop rivets for duct assembly.
FOR BEST DRYING:
1.Make-up air from outside the building may enter the enclosure from
the top or side walls. The area of the opening must be a minimum of
210 square inches (135484 mm²) for each dryer. This will deliver the
proper amount of make-up air at an air velocity of approximately
500 fpm (152 m/min) through the opening.
2.Use barometric shutters in the inlet air opening to control air when
dryers are not running.
OTHER
RECOMMENDATIONS
TROUBLESHOOTING
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 makeup 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. CAUTIONNever 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
Wiring diagrams are located on the rear cover 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 restart your dryer to remove wrinkles.

Direct-Spark Ignition Operation
DIRECT SPARK
IGNITION
OPERATION
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 as 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
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 basket shaft bearings 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 inside the rear
cover of the dryer, and front bolts are inside lint trap
compartment.

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.
