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 YOURSAFETY
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.
FIREAND EXPLOSION WILLOCCUR. NEVER PUT FABRICSTREATED WITH THESELIQUIDS
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.

Gas Piping Information
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.

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.

WARNING:
LIQUIFIEDPETROLEUMGASESONLY
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.

1. Make-upairfromoutsidebuildingmayenterenclosurefromtopor
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:3-12inch(305 mm) diameterduct=1-20.78inch
(528 mm) diameter duct in area. Use 21 inch (534 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.
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/hr per square foot.
6. Flangemounted,beltdriventube-axialfan.Fanmustrun
whenone or more dryersare running.See suggested
Automatic Electrical Control Wiring Diagram on previous
page. Must meet local electrical codes. Fan air flow (cfm) 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
locatedwithinenclosure.
CAUTION: Never install hot water heaters or other gas
appliancesinthe sameroomas dryers.Neverinstallcooling
exhaust fans in the same room as dryers.
