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/General Installation (All Dryers)
UNPACKING
GENERAL
INSTALLATION
(ALL DRYERS)
This dryer is packed in a large (heavy-duty) protective wooden crate.
Upon arrival of the equipment, any damage in shipment should be
reported to the carrier immediately.
Upon determining permanent location of a unit, care should be
taken in movement and placement of equipment. To move dryer
through doorways, you may need to remove the top of the machine.
Follow instructions for disassembling.
See outline clearance diagrams for correct dimensions.
Remove all packing material such as: tape, manuals, skid, etc.
Check voltage and amperes on rating plate before installing the
dryer.
IMPORTANT
Before installing or operating this dryer, thoroughly read the owner's manual for correct instructions concerning electric connections, exhaust
ducting, gas piping, steam connections, make-up
air, etc.
IMPORTANT
Read the warnings in this manual.
IMPORTANT
Do not install this dryer in an area where it will be
exposed to water and/or weather.
IMPORTANT
Failure to follow these instructions and warnings
may create a safety hazard and may affect the warranty.
IMPORTANT
Follow all local codes.
IMPORTANT
If you have any installation questions, consult the
factory Service Department.

General Installation (All Dryers)
GENERAL
INSTALLATION
(ALL DRYERS)
GENERAL
IMPORTANT
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 for gas dryers is
18” (458 mm) ceiling clearance, 24” (610 mm) rear clearance, and 24” (610 mm) side clearance. Installation clearance from all combustable material for steam dryers is
14” (356 mm) ceiling clearance, 24” (610 mm) rear clearance, and 18” (458 mm)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.
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 venting and eventually to the atmosphere. The lint accumulates in the
drawer and should be removed as needed, minimum once
daily.
-
IMPORTANT
Provide adequate clearance for air openings into
the combustion chamber.
REPLACEMENT
PART S
Replacement parts for this dryer are available from your
distributor or by contacting the factory at the address or
phone number printed on the cover of this manual.
WARNING Unit is heavy!
NOTE
The gas installation must conform with local codes
or, in the absence of local codes, with the National
Fuel Gas Code, ANSI Z223.1 - “Latest Edition”.

GROUNDING
INSTRUCTIONS
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
No. 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 with the Service Connection Box on the rear of
the dryer. 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.
«Attention. Lors des opérations d’entretien
des commandes, ètiqueter tous les fils avant
de les dèconnecter. Toute erreur de câblage
peut être une source de danger et de panne»

GAS PIPING
INSTALLATION
Gas Piping Installation
1. Gas service 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 Rating Plate located on rear wall of dryer, for type of
gas to equip the dryer and the altitude (elevation).
3. Check with the gas supplier for the gas pressure and the
proper gas supply line installation.
NOTE: The dryer and its 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 psig (3.5 kPa).
The dryer must be isolated from the gas supply piping
system by closing its individual manual shutoff valve
during any pressure testing of the gas supply piping system at test pressures equal to or greater than 1/2 psig
(3.5 kPa).
CAUTION: Low gas pressure and intermittent gas will
cause gas ignition problems. This will cause inadequate
drying of the clothes load.
NATURAL GAS ONLY
NATURAL GAS ONLY: Check the gas pressure inlet supply
to the dryer, 11” w.c. (27.4 mbar) pressure maximum. Check
the manifold pressure, 3.5” w.c. (8.8 mbar) pressure inside
the dryer.
CAUTION: Gas loop piping must be installed as shown on
the previous page, to maintain equal pressure for all dryers connected to a single gas service. Install other gas
appliances upstream from the loop.
Specific gas pipe size should be obtained from your supplier or
refer to the Gas Pipe Size Chart in this manual.
