WARNINGS ABOUT USE AND OPERATION
DO NOT MODIFY THIS APPLIANCE. KEEP SHIELDS, GUARDS, AND COVERS IN PLACE. These
safety devices are provided to protect everyone from inj ry.
It is ABSOLUTELY ESSENTIAL that the dryer be gro nded to a known earth (zero) gro nd 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, b t is necessary
for proper operation of the controller. Fail re to do so will void 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 occ r d ring this "power p" period, are
s bject to loss in case of power interr ption. After the initial three min tes, all programmed data is protected
from power interr ptions of any length and the c stomer's individ al cycle is protected p to 3 seconds. This is
done witho t batteries.
LEAVE THE ELECTRICAL POWER TO THE DRYER ON AT ALL TIMES except when necessary for service
or other similar activities. The ho r meter f nction adds only f ll ho rs to its reading. If the power is sh t off every night,
any fraction of an ho r of time that is on the machine at that time will be lost. T rning the power off every night
co ld also have some effect on the long-term life of the memory after a n mber of years. T rning power off
occasionally won’t affect the nit.
THIS DRYER IS EQUIPPED WITH AN OVER-TEMPERATURE THERMOSTAT located on the end of
the b rner ho sing above the gas valve. Sho ld the dryer cease to operate, refer to yo r “Service Proced re and
Parts Data” book for instr ctions.
CHECK THIS THERMOSTAT WHEN INSTALLING DRYER to ass re it is not tripped. Impacts s ch as
ro gh handling in shipment, may trip the thermostat. It may be reset by inserting a wooden pencil or dowel
thro gh the b shing in the cover.

INSTALLATION AND OPERATING INSTRUCTIONS
This dr er ma have been supplied as part of a washer/dr er stacked appliance. If
so, refer to the washer instructions for uncrating and hard mounting the stacked
unit to a concrete floor and observe the dr er clearances listed below.
STACK WASHER /DRYER INSTALLATION (when necessary):
1. Place dryer on top of washer and align (4) mo nting holes. The front (2) mo nting holes are located inside
the lint compartment 5 ½” from the front of the machine. The back (2) mo nting holes are located on the
right/left side of the machine, at the base of the back panel. Removing the rear g ard is necessary to access
the back mo nting hole located opposite the d ct work.
2. Use (4) s pplied 5/16” x 1-1/4 dog tip bolts to sec re the dryer on top of the washer.
DRYER INSTALLATION
1. CODE CONFORMITY. All commercial dryer installations m st conform with local codes or, in the absence of
local codes, with the latest edition of the National F el Gas Code ANSI Z223.1A. Canadian installations m st
comply with c rrent Standard CAN/CGA-B149 (.1 or .2) Installation Code for Gas B rning Appliances or Eq ipment,
and local codes if applicable. A stralian installations m st meet installation req irements and pipe sizing
req irements of AS/NZA 5601. The appliance, when installed, m st be electrically gro nded in accordance with
the latest edition of the National Electrical Code, ANSI/NFPA70, or, when installed in Canada, with Standard CSA
C22.1 Canadian Electrical Code Part 1.
2. INSTALLATION CLEARANCES. This nit may be installed at the following alcove clearance. (millimeters)
I. Left Side 0”
II. Right Side 0” *
III. Back 18” (457) (Certified for 1” (25) clearance; however, 18” (457) clearance is necessary behind
the belt g ard to allow servicing and maintenance.)
IV. Front 48” (1220) (to allow use of dryer)
V. Top Refer to fig re on the next page labeled “Vertical Clearance Dimensions”.
Certification allows 0” clearance at the top 1” (25) back from the front. However, a 1/4” (6)
clearance is req ired to allow opening the pper service door.
A 10” (254) clearance is required fro the top at all other points.
VI. Floor This nit may be installed pon a comb stible floor.
Do not obstr ct the flow of comb stion and ventilation air.
Maintain minim m of 1” (25mm) clearance between d ct and comb stible material.
Refer to installation label attached to the rear g ard of the dryer for other installation information.

8514-272-001 REV C page 8
3. MAKE-UP AIR. Adeq ate make- p air m st be s pplied to replace air exha sted by dryers on all types of
installations. Refer to specifications for the minim m amo nt of make- p air opening to o tside for each dryer. This is a
net req irement of effective area. Screens, grills or lo vers, which will restrict the flow of air, m st be considered.
Cons lt the s pplier to determine the free area eq ivalent for the grill being sed. The so rce of make- p air sho ld be
located s fficiently away from the dryers to allow an even airflow to the air intakes of all dryers. M ltiple openings
sho ld be provided.
The so rces of all make- p air and room ventilation air movement to all dryers m st be located away from any
dry cleaners. This is necessary so that solvent vapors will not be drawn into the dryer inlet d cts. Dry cleaner
solvent vapors will decompose in contact with open flame s ch as the gas flame present in clothes dryers. The
decomposition prod cts are highly corrosive and will ca se damage to the dryer(s) d cts and clothes loads.
4. ELECTRICAL REQUIREMENTS. The electrical power req irements necessary to operate the nit satisfactorily are
listed on the serial plate located on the back panel of each dryer and in the specifications section of this man al.
The electrical connection sho ld be made to the terminal board, on the rear of the nit. It is absol tely necessary
that the dryer be gro nded to a known gro nd. Individ al circ it breakers for each dryer are req ired.
Individ al circ it breakers for each nit are recommended. Do not se gro nd-fa lt circ it breakers or gro nd-
fa lt circ it interr pter o tlets. The wiring diagram is located on the belt g ard on the back of the machine.
IMPORTANT: TRANSIENT VOLTAGE SURGE SUPPRESSORS
Like most electrical eq ipment, yo r new machine can be damaged or have its life shortened by voltage s rges
d e to lightening strikes which are not covered by factory warranty. Local power distrib tion problems also can
be detrimental to the life of electrical components. We recommend the installation of transient voltage s rge
s ppressors for yo r new eq ipment. These devices may be placed at the power s pply panel for the complete
installation and don’t req ire an individ al device for each machine.
These s rge protectors help to protect eq ipment from large spikes and also from small ongoing spikes in the
power that occ r on a day to day basis. These smaller s rges can shorten overall life of electrical components of
all types and ca se their fail re at a later date. Altho gh they can’t protect against all events, these protective
devices have a good rep tation for significantly lengthening the sef l life of electronic components. Electronic

8514-272-001 REV C page 9
components are helped to have a longer sef l life when they are s pplied with the clean stable electrical power
they like.
We are incl ding the following names and phone n mbers of a few s ppliers of these devices for those who don’t
c rrently have a so rce.

5. GAS REQUIREMENTS. The complete gas req irements 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 nit is 1/2 inch pipe thread.
An individ al gas sh toff valve is recommended for each dryer and may be req ired by local code (not
s pplied).
A joint compo nd resistant to the action of liq efied petrole m gases sho ld be employed in making pipe
connections.
A 1/8 inch NPT pl gged tapping, accessible for test gage connection, m st be installed immediately pstream
of the gas s pply connection to the dryer.
A drip tee sho ld be provided in the gas piping entering the nit to catch dirt and other foreign articles.
All pipe connections sho ld be checked for leakage with soap sol tion. Never check with an open flame.
For altit des above 2,000 feet (610m) it is necessary to de-rate the BTU inp t. Contact yo r local distrib tor
for instr ctions.
L.P. gas conversion kits are available for this dryer. Contact yo r local distrib tor.
CAUTION: The dryer m st be disconnected from the gas s pply piping system d ring any press re testing of
that system. Do not expose the dryer’s gas control valve to testing press re.
6. EXHAUST INSTALLATION. Exha sting of the dryer(s) sho ld be planned and constr cted so that no air
restrictions occ r. Any restriction d e to pipe size or type of installation can ca se slow drying time, excessive
heat, and lint in the room.
From an operational standpoint, incorrect or inadeq ate exha sting can ca se a cycling of the high limit thermostat
which sh ts off the main b rners and res lts in inefficient drying.
Individ al exha sting of the dryers is recommended. All heat, moist re, and lint sho ld be exha sted o tside
by attaching a pipe of the proper diameter to the dryer adapter collar and extending it o t thro gh an o tside wall.
This pipe m st be very smooth on the inside, as ro gh s rfaces tend to collect lint which will event ally clog the
d ct and prevent the dryer from exha sting properly. All elbows m st be smooth on the inside. All joints m st be
made so the exha st end of one pipe is inside the next one downstream. The addition of an exha st pipe
tends to red ce the amo nt of air the blower can exha st. This does not affect the dryer operation if held within
practical limits. For the most efficient operation, it is recommended that no more than 20' (6m) of straight 8”
(204mm) diameter pipe be sed with two right angle elbows. When more than two elbows are sed, 2' (600mm)
of straight pipe sho ld be removed for each additional elbow. No more than fo r right angle elbows sho ld be
sed to exha st a dryer.
Maintain minim m 1” (25) clearance between d ct and comb stible material.
If the exha st pipe passes thro gh a wall, a metal sleeve of slightly larger diameter sho ld be set in the wall and
the exha st pipe passed thro gh this sleeve. This practice is req ired by some local codes and is recommended in

8514-272-001 REV C page 10
all cases to protect the wall. This type of installation sho ld have a means provided to prevent rain and high winds
from entering the exha st when the dryer is not in se. A hood with a hinged damper can be sed for this p rpose.
Another method wo ld be to point the o tlet end of the pipe downward to prevent entrance of wind and rain. In
either case, the o tlet sho ld be kept clear, by at least 24” (610), of any objects which wo ld ca se an air
restriction.
Never install a protective screen over the exha st o tlet.
When exha sting a dryer straight p thro gh a roof, the overall length of the d ct has the same limits as exha sting
thro gh a wall. A rain cap m st be placed on top of the exha st and m st be of s ch a type as to be free from
clogging. The type sing a cone shaped “roof” over the pipe is s itable for this application.
Exha sting the dryer into a chimney or nder a b ilding is not permitted. In either case there is a danger of
lint b ild- p which can be highly comb stible.
Installation of several dryers, where a main discharge d ct is necessary, will need the following considerations for
installation. Individ al d cts from the dryers into the main discharge d ct sho ld be at a 45 degree angle in the
direction of discharge air flow.
NOTE: Never install the individ al d cts at a right angle into the main discharge d ct. The individ al
d cts from the dryers can enter at the sides or bottom of the main discharge d ct. The main d ct can be
rectang lar or ro nd, provided adeq ate air flow is maintained. For each individ al dryer, the total exha sting
(main discharge d ct pl s d ct o tlet from the dryer) sho ld not exceed the eq ivalent of 14 feet (6m) and
two elbows. The diameter of the main discharge d ct at the last dryer m st be maintained to exha st end.
NOTE: A small diameter d ct will restrict air flow; a large diameter d ct will red ce air velocity – both
contrib ting to lint b ild p. An inspection door sho ld be provided for periodic clean-o t of the main
d ct.
NOTE: STATIC BACK PRESSURE sho ld be a maxim m of 0.3 at the rear exha st o tlet of the dryer. If
m ltiple dryers are connected to the common d ct, ens re the back draft damper is installed properly.
