IMPORTANTNOTICESPLEASEREAD
For optimum efficiency and safety, we recommend that you read the manual before operating the equipment. Store this manual in a
file or binder and keep for future reference.
WARNING: For your safety, the information in this manual must be followed to minimize
the risk of fire or explosion or to prevent property damage, personal injury or loss of life.
- Do not store or use gasoline or other flammable vapors or liquids in the vicinity of this or
any other appliance.
- WHAT TO DO IF YOU SMELL GAS
 Do not try to light any appliance.
 Do not touch any electrical switch; do not use any phone in your building.
 Clear the room, building or area of all occupants.
 Immediately call your gas supplier from a neighbor's phone. Follow the gas supplier's
instructions.
 If you cannot reach your gas supplier, call the fire department.
Installation and service must be performed by a qualified installer, service agency or the gas
supplier.
WARNING: In the event the user smells gas odor, instructions on what to do must be posted in a
prominent location. This information can be obtained from the local gas supplier.
WARNING: Wear safety shoes to prevent injuries.
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 3
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 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.

INSTALLATION
(ALL DRYERS)

Page 10
General Installation (All Dryers)
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 24 ceiling clearance, 24
rear clearance, and 0 side clearance. Installation clearance from
all combustable material for steam dryers is 24 ceiling clearance,
24 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.
The dryer is so designed that when an operator opens the dryer
door, the basket and exhaust fan stop. 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 collector and should be removed as needed,
minimum once daily.
IMPORTANT
Provide adequate clearance for air openings into the combustion
chamber.
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 or the CAN/CGA-B149, Installation Codes.

175 lb. Steam Heated Laundry Dryers - Specifications
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 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.
CAUTION: Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper operation.
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.
