W ARNINGS ABOUT USE AND OPERATION
KEEP SHIELDS, GUARDS AND COVERS IN PLACE. These safety devices are provided to protect everyone
from injury.
It is ABSOLUTELY ESSENTIAL that the dryer be grounded to a known earth (zero) ground in accordance with
local codes or, in the absence of local codes, with the latest editions of the National Electric Code, ANSI//NFPA 70
or Standard CSA C22.1 Canadian Electrical Code Part 1. This is not only for personal safety, but is necessary for
proper operation of the controller. Failure to do so will void the warranty of the controller.
LEAVE THE ELECTRICAL POWER TO THE DRYER ON AT ALL TIMES except when necessary for service
or other similar activities. The hourmeter function adds only full hours to its reading. If the power is shut off every night,
any fraction of an hour of time that is on the machine at that time will be lost. Turning the power off every night could
also have some effect on the long term life of the memory after a number of years. Turing power off occasionally won’t
affect the unit.
From a safety aspect shutting off the gas supply at night would be better than shutting off the electrical power.
THIS DRYER IS EQUIPPED WITH AN OVER-TEMPERATURE THERMOSTAT located on the end of the
burner housing above the gas valve. Should the dryer cease to operate, refer to your “Service Procedure and Parts
Data” book for instructions.
CHECK THIS THERMOSTAT WHEN INSTALLING DRYER to assure it is not tripped. Impacts such as rough
handling in shipment, may trip the thermostat. It may be reset by inserting a wooden pencil or dowel through the
bushing in the cover.

INSTALLATION AND OPERATING INSTRUCTIONS
UNCRATING AND PLACING DRYER
Tools Required: 3/4" hex socket & ratchet driver, wood block 4" or 5" thick, a knife and a groove joint plier which will
open to 1 3/8".
1. Remove and discard packaging.
2. The crate base is attached to the dryer by (4) cap screws driven upward from below the crate base. Remove crate
base from dryer, by tipping dryer sidewise and place block under crate base rail in center of dryer. Using a ratchet
and 3/4" hex socket remove and discard (2) crating bolts from side which is raised. Remove block from under crate
base. Repeat for other side.
3. Install leveling legs. Using a walking motion, move dryer sideways about 6" off crate base. Tip dryer up and place
block under edge of dryer. Thread two leveling legs about two-thirds into the T-nuts on the base from which the crating
bolts were removed. Remove block from under dryer.
With a walking motion move dryer completely off crate base. Discard crate base.
Tip dryer sidewise, as previously done, and place block under edge of dryer on raised side. Thread leveling legs
into nuts as was done for the first side.
Slide unit into position where it will be installed. Adjust leveling legs, using the groove joint plier, to level and align
dryer with adjacent units.
DRYER INSTALLATION
1. CODE OF CONFORMITY. All commercial dryer installations must conform with local codes or, in the absence
of local codes, with the Nation Fuel Gas Code ANSI Z223.1A. Canadian installations must comply with current
Standard CAN/CGA-B149 (.1 or .2) Installation Code for Gas Burning Appliances or Equipment, and local codes if
applicable. The appliance, when installed, must be electrically grounded in accordance with the National Electric
Code, ANSI/NFPA No. 70-1990, or, when installed in Canada, with Standard CSA C22.1 Canadian Electrical Code
Part 1.
2. INSTALLATION CLEARANCES: This unit may be installed at the following alcove clearance. (millimeters)
I. Left Side 0"
II. Right Side 0"
III. Back 18" (457) (Certified for 6" (152) clearance; however, 18" (457) clearance is necessary behind
the motors to allow servicing and maintenance.)
IV. Front 48" (1220) (to allow use of dryer)
V. Top Refer to figure labeled “Vertical Clearance Dimensions”.
AB. Certification allows 0" clearance at the top 4" (102) back from the front.
However, a 1/4" (6) clearance should be allowed in case the dryer needs moving.
C. A 10" (254) clearance is required from top at all other points.
VI. Floor This unit may be installed upon a combustible floor.
Do not obstruct the flow of combustion and ventilation air.
Maintain minimum of 1" (25) clearance between duct and combustible material.
Refer to the label attached to the Belt Guard on the rear of the dryer for other installation information and start-up
instructions.
3. MAKE-UP AIR. Adequate make-up air (600CFM/DRUM, 1200CFM/DRYER) must be supplied to replace air
exhausted by dryers on all types of installations. Provide a minimum of 1 1/2 square feet make-up air opening to outside
for each dryer. This is a net requirement of effective area. Screens, grills or louvers which will restrict the flow of air
must be considered. Consult the supplier to determine the free area equivalent for the grill being used.
The source of make-up air should be located sufficiently away from the dryers to allow an even air flow to the air
intakes of all dryers. Multiple openings should be provided.
NOTE: The following considerations must be observed for gas dryer installations where dry cleaners are installed.
4
The sources of all make-up air and room ventilation air movement to all dryers must be located away from any dry
cleaners. This is necessary so that solvent vapors will not be drawn into the dryer inlet ducts. Dry cleaner solvent
vapors will decompose in contact with open flame such as the gas flame present in clothes dryers. The decomposition
products are highly corrosive and will cause damage to the dryer(s) ducts and clothes loads.
4. ELECTRICAL REQUIREMENTS. The electrical power requirements necessary to operate the unit satisfactorily
are listed on the serial plate located on the back panel of each dryer. The electrical connection should be made to
the terminal board, on the rear of the unit, using #10 AWG wire for 120V, #12 AWG for 208-240V (neutral required).
It is absolutely necessary that the dryer be grounded to a known ground.
Individual circuit breakers for each stacked dryer are required. Use 30A circuit breakers for 120V and 15A or
20A circuit breakers for 208-240V. This dryer is adjusted for 120V as shipped. Conversion instructions to
208-240V (neutral required) are at the end of this booklet.
5. GAS REQUIREMENTS. The complete gas requirements necessary to operate the dryer satisfactorily are listed
on the serial plate located on the back panel of the dryer.
The inlet gas connection to the unit is 1/2 inch pipe thread. However, the size of the piping to supply the dryer should
be determined by reference to the National Fuel Gas Code ANSI Z223.1A and consultation with the local gas supplier.
A joint compound resistant to the action of liquefied petroleum gases should be employed in making pipe
connections.
A 1/8 inch NPT plugged tapping, accessible for test gage connection, must be installed immediately upstream of
the gas supply connection to the dryer.
A drip tee is provided in the unit gas piping to catch dirt and other foreign articles.
All pipe connections should be checked for leakage with soap solution. Never check with an open flame.
For altitudes above 2,000 feet (610m) it is necessary to derate the BTU input. Contact your local distributor for
instructions.
L.P. gas conversion kits are available for this dryer. Contact your local distributor.
