IMPORTANT NOTICES—PLEASE READ

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 thegas 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 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 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.

General Installation (All Dryers)

GENERAL
INSTALLATION
(ALL DRYERS)

GENERAL

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 0” ceiling clearance, 24” rear clearance, and
0” side clearance. Installation clearance from all combustable material
for steam dryers is 0” 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

REPLACEMENT
PARTS

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.

General Information

GENERAL
INFORMATION

ELECTRICAL
CONNECTIONS

The dryer is so designed that when an operator opens the dryer door, the
basket stops. 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, self-cleaning lint screen. In this system, lint accumulates on the
underside of the screen until a blanket approximately 1/4” (7 mm) thick
is formed. This 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.

Gas Piping Information

GAS PIPING

NATURAL GAS ONLY

LP GAS ONLY

Check gas rating plate for type of gas to equip the dryer.

Check for altitude elevation of the dryer.

Check utility for proper installation of gas supply line and gas
pressure.

NATURAL GAS ONLY

Check the gas pressure inlet supply to dryer, 11 inches Water Column
Pressure (27.4 mbar) maximum. Check the manifold pressure,

3.5 inches Water Column Pressure (8.8 mbar) (Natural Gas).

LP GAS ONLY

11 inches Water Column Pressure (27.4 mbar) maximum.

CAUTION: Low gas pressure and intermittent gas will
cause gas ignition problems. This will cause inadequate
drying of the clothes load.

The dryer and its individual shut-off 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 (.04 bar).

The dryer must be isolated from the gas supply piping system by
closing its individual manual shut-off valve during any pressure
testing of the gas supply piping system at test pressures equal to
or less than 1/2 psig (.04 bar).

Gas Service Installation Information

GENERAL
INSTALLATION
FOR ALL DRYERS

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.
