WARNINGS ABOUT USE AND OPERATION
DO NOT MODIFY THIS APPLIANCE. KEEP SHIELDS, GUARDS AND COVERS IN PLACE. These safety
de ices are pro ided to protect e eryone 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 oid the warranty of the controller.
A DRYER SHOULD BE CONNECTED TO POWER FOR THREE (3) MINUTES before it is operated or
before a program change is made. Operation or program changes, which occur during this "power up" period, are
subject to loss in case of power interruption. After the initial three minutes, all programmed data is protected
from power interruptions of any length and the customer's indi idual cycle is protected up to 3 seconds. This is
done without batteries.
LEAVE THE ELECTRICAL POWER TO THE DRYER ON AT ALL TIMES except when necessary for ser ice
or other similar acti ities. The hour meter function adds only full hours to its reading. If the power is shut off e ery night,
any fraction of an hour of time that is on the machine at that time will be lost. Turning the power off e ery night
could also ha e some effect on the long-term life of the memory after a number of years. Turning power off
occasionally won’t affect the unit.
THIS DRYER IS EQUIPPED WITH AN OVER-TEMPERATURE THERMOSTAT located on the end of
the burner housing abo e the gas al e. Should the dryer cease to operate, refer to your “Ser ice 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 co er.
DO NOT SPRAY AEROSOLS IN THE VICINITY OF THIS APPLIANCE while it is in operation.
THIS APPLIANCE SHALL NOT BE USED TO DRY OFF CLOTHES CONTAINING SOLVENTS OR DRY
CLEANING FLUIDS.

INSTALLATION INSTRUCTIONS
This dryer may have been supplied as part of a washer/dryer stacked appliance. If
so, refer to the washer instructions for uncrating and hard mounting the stacked
unit to a concrete floor and observe the dryer clearances listed below.
STACK WASHER / DRYER INSTALLATION (when necessary):
1. Place dryer on top of washer and align (4) mounting holes. The front (2) mounting holes are located inside
the lint compartment 5 ¾” from the front of the machine. The back (2) mounting holes are located on the
right/left side of the machine, at the base of the back panel. Remo ing the rear guard is necessary to access
the back mounting hole located opposite the duct work.
2. Use (4) supplied 5/16” x 1-1/4 dog tip bolts to secure the dryer on top of the washer.
DRYER INSTALLATION
1. CODE CONFORMITY: All commercial dryer installations must conform with local codes, or in the absence of
local codes, with the latest edition of the National Fuel Gas Code ANSI Z223.1. Canadian installations must
comply with the current Standard CAN/CGA-B149 (.1 or .2) Installation Code for Gas Burning Appliances or
Equipment, and local codes if applicable. Australian installations must meet installation requirements and pipe
sizing requirements of AS/NZA 5601. The appliance, when installed, must be electrically grounded in
accordance with the latest edition of the National Electric Code, ANSI/NFPA70, 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 alco e clearances:
I. Left Side 0"
II. Right Side 0"
III. Back 18" (457 mm) (Certified for 6" (150 mm) clearance; howe er, 18" (457 mm) clearance is
necessary behind the motors to allow ser icing and maintenance.)
IV. Front 48" (1220 mm) (to allow use of dryer)
V. Top Refer to figure labeled “Vertical Clearance Dimensions”.
AB. Certification allows 0" clearance at the top 4" (100 mm) back from the front.
Howe er, a 1/4" (6 mm) clearance should be allowed in case the dryer needs to be
mo ed.
C. A 10" (250 mm) clearance is required from top at all other points.
VI. Floor If used as a stand-alone dryer, this unit is intended to be installed upon an ele ated
surface. The surface must be of suitable strength to support 450 pounds (205 kg),
and the dryer should be bolted or anchored to pre ent horizontal mo ement. This
unit may be installed upon a combustible floor.
Do not obstruct the flow of combustion and entilation air.
Maintain minimum of 1" (25 mm) 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.

8514-286-001 REV B PAGE 7
FIGURE 2 - VERTICAL CLEARANCE DIMENSIONS
3. MAKE-UP AIR: Adequate make-up air must be supplied to replace air exhausted by dryers on all types of
installations. Refer to specifications for the minimum amount of make-up air opening to outside for each dryer.
This is a net requirement of effecti e area. Screens, grills or lou ers, which will restrict the flow of air, must be
considered. Consult the supplier to determine the free area equi alent for the grill being used. The source of
make-up air should be located sufficiently away from the dryers to allow an e en airflow to the air intakes
of all dryers. Multiple openings should be pro ided.
The sources of all make-up air and room entilation air mo ement to all dryers must be located away
from any dry cleaners. This is necessary so that sol ent apors will not be drawn into the dryer inlet
ducts. Dry cleaner sol ent apors will decompose in contact with open flame such as the gas flame present
in clothes dryers. The decomposition products are highly corrosi e 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 and in the specifications section of
this manual. The electrical connections should be made to the terminal board in the electrical control box

8514-286-001 REV B PAGE 8
on the rear of the unit. It is absolutely necessary that the dryer be grounded to a known ground.
Indi idual circuit breakers for each dryer are required.
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 and in the specifications section of this
manual. The inlet gas connection to the unit is 1/2-inch pipe thread. Howe er, 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.
An indi idual gas shutoff al e is recommended for each dryer and may be required by local code (not
supplied).
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 pro ided in the unit gas piping to catch dirt and other foreign articles.
All pipe connections should be checked for leakage with soap solution. Ne er check with an open flame.
For altitudes abo e 2,000 feet (610m), it is necessary to de-rate the BTU input. Contact your local
distributor for instructions.
L.P. gas con ersion kits are a ailable for this dryer. Contact your local distributor.
CAUTION: The dryer must be disconnected from the gas supply piping system during any pressure
testing of that system. Do not expose the dryer’s gas control al e to testing pressure.
6. EXHAUST INSTALLATION. (Refer to Figure 3) Exhausting of the dryer(s) should be planned and
constructed so that no air restrictions occur. Any restriction due to pipe size or type of installation can
cause slow drying time, excessi e heat, and lint in the room.
From an operational standpoint, incorrect or inadequate exhausting can cause a cycling of the high limit
thermostat, which shuts off the main burners and results in inefficient drying.
The exhaust duct connection near the top of the dryer will accept a 6” (152 mm) round duct. Indi idual
exhausting of the dryers is recommended. All heat, moisture, and lint should be exhausted outside by
attaching a pipe of the proper diameter to the dryer adapter collars and extending it out through an
outside wall. This pipe must be ery smooth on the inside, as rough surfaces tend to collect lint, which
will e entually clog the duct and pre ent the dryer from exhausting properly. All elbows must be
smooth on the inside. All joints must be made so the exhaust end of one pipe is inside the next one
downstream. The addition of an exhaust pipe tends to reduce the amount of air the blower can exhaust.
This does not affect the dryer operation if held within practical limits. For the most efficient operation, it
is recommended that no more than 14 ft. (4.25 m) of straight 6 in. (152 mm) diameter pipe with two
right angle elbows be used for each cylinder.
Maintain a minimum of 1” (25mm) clearance between duct and combustible material.
If the exhaust pipe passes through a wall, a metal slee e of slightly larger diameter should be set in the
wall and the exhaust pipe passed through this slee e. This practice is required by some local codes and is
recommended in all cases to protect the wall.
This type of installation should ha e a means pro ided to pre ent rain and high winds from entering the
exhaust when the dryer is not in use. A hood with a hinged damper can be used for this purpose.
Another method would be to point the outlet end of the pipe downward to pre ent entrance of wind
and rain. In either case, the outlet should be kept clear, by at least 24 in. (610 mm) of any objects,
which would cause air restriction.

8514-286-001 REV B PAGE 9
Ne er install a protecti e screen o er the exhaust outlet.
When exhausting a dryer straight up through a roof, the o erall length of the duct has the same limits as
exhausting through a wall. A rain cap must be placed on top of the exhaust and must be of such a type
as to be free from clogging. The type using a cone shaped “roof” o er the pipe is suitable for this
application.
Exhausting the dryer into a chimney or under a building is not permitted. In either case there is a danger
of lint buildup, which can be highly combustible.
Installation of se eral dryers, where a main discharge duct is necessary, will need the following
considerations for installation (see Figure 3). Indi idual 6” (152 mm) exhaust ducts from each dryer
should enter main discharge duct at a 45-degree angle in the direction of discharge airflow.
NOTE: Ne er install the indi idual ducts at a right angle into the main discharge duct.
The indi idual ducts from the dryers can enter at the sides or bottom of the main discharge
duct. Figure 3 indicates the arious round main duct diameters to use with the indi idual
dryer ducts. The main duct can be rectangular or round, pro ided adequate airflow is
maintained. The total exhausting (main discharge duct plus duct outlet from the dryer)
should not exceed the equi alent of 14 ft. (4.25 m) and two elbows. The diameter of the
main discharge duct at the last dryer must be maintained to exhaust end.
NOTE: A small diameter duct will restrict airflow; a large diameter duct will reduce air
elocity - both contributing to lint build up. An inspection door should be pro ided for
periodic clean out of the main duct.
7. DRYER IGNITION (SOLID STATE IGNITION): The solid-state ignition system lights the main burner gas by spark.
The gas is ignited and burns only when the gas-relay (in the electronic controller) calls for heat. The procedure for
first-time starting of a dryer is as follows.
i. First re iew and comply with the "Warnings About Use and Operation" found on the inside front co er
of this manual. Be sure electrical power is connected correctly. The dryer must be properly grounded.
ii. Make sure all gas supply lines are purged of air. Close the main gas shut-off al e and wait for fi e
minutes before turning it back on.

8514-286-001 REV B PAGE 10
iii. Turn on the main electrical power switch. The dryer may be started by following the "Operating
Instructions" found later in this manual.
i . Natural gas and LPG fired dryers operate in the same manner. When the gas al e relay contacts are
closed (indicating a demand for heat), the solid-state ignition control will automatically supply energy to the
redundant gas al e. Sparking will continue until a flame is detected by the sensing probe, but not longer than
ten seconds. If the gas fails to ignite in 10 seconds, the gas al e closes and the gas system pauses to allow gas to
purge from the inside of the dryer. After the pause, the ignition control repeats the ignition trial cycle twice more.
If the gas system fails to detect ignition after the three attempts, the system will "lock out". No further attempts
will be performed automatically. To reset the ignition control electrical power to the ignition control must be
interrupted. This can be done by opening the dryer door (stopping the dryer) for 15 seconds. Closing the door and
pushing the "Start" button will repeat the ignition trial cycle.
DRYER SHUTDOWN
To render the dryer inoperati e, turn off the main gas shut off al e and disconnect the electrical supply to the
dryer.
NOTE: It is recommended that the installer test the dryer for operation and instruct the
user before lea ing the installation.
