(for Electrical Connections).
A. UNPACKING/SETTING UP
Remove protective shipping material (i.e., plastic wrap and/or optional shipping box) from dryer.
NOTE: Theaccesskeysfor the service doorsareincludedintheinformationpacketshipped in the
basket (tumbler). These keysshouldberemovedandputin a safeplaceyetmadeaccessible
becausesome will be neededthroughoutvariousphasesintheinstallationofthedryer.
Dryers are shipped with a coin box and coin box faceplate ONLY. The coin box lock is not included and
must be purchased elsewhere or the lock can be ordered as a parts order from the manufacturer.
The dryer can be moved to its final location while still attached to the skid or with the skid removed. To unskid
the dryer, locate and remove the four (4) bolts securing the base of the dryer to the wooden skid. Two (2) are
at the rear of the base, and two (2) are located in the front. Once the bolts are removed, slide the dryer off the
skid.
With the skid removed, to make it easier to slide the dryer into its final position, slightly lower ALL four (4)
leveling legs, so that the dryer will slide on the legs instead of the base frame. The dryer is equipped with four
(4) leveling legs, one (1) at each corner of the dryer base. The hex head adjustment bolts for the two (2) front
leveling legs are located directly behind the lower access door, and the rear two (2) adjustments are directly
behind the lower rear back (guard) panel.
To facilitate door closure and better tumbling action (and improved efficiency), the dryershould betiltedslightly
to the rear.
B. LOCATION OF THE DRYER
Before installing the dryer, be sure the location conforms to local codes and ordinances. In the absence of such
codes or ordinances the location must conform with the National Fuel Gas Code ANSI.Z223.1-LATEST
EDITION, or in Canada, the Canadian Installation Codes CAN/CGA-B149.1-M91 (Natural Gas) or CAN/
CGA-B149.2-M91 (L.P. Gas) or LATEST EDITION.

Dryers may be positioned sidewall to sidewall. However, allowancesmustbe made for the opening and closing
of the control door and the lint door. It is suggested that the dryer be positioned about 2 feet (0.61 meters) away
from the nearest obstruction for ease of installation, maintenance, and service (to be measured from the back
guard). Refer to the illustration on the previous page for details.
NOTE: Airconsiderationsareimportantforproperandefficientoperation.

10 Maytag 113203-3
D. FRESH AIR SUPPLYREQUIREMENTS
Air supply (make-up air)must begiven careful consideration to ensure proper performance of each dryer. An
unrestricted source of 800 cfm (22.65 cmm) is necessary for each dryer. An unrestricted air entrance from the
outdoors (atmosphere) of a minimum of 1-1/2 square feet (0.14 square meters) is required for each dryer. This
area must be enlarged if louvers or registers cover the opening. It is not necessary to have a separate
make-up air opening for each dryer. Common make-up air openings are acceptable. However, they must be
set up in such a manner that the make-upair is distributed equally to the dryers. For example, for a bank of eight
(8) dryers, a total make-up air opening of 12 square feet (1.15 square meters) is required. Two (2) openings
measuring 2 feet by 3 feet (0.61 meters by 0.91 meters [6 square feet] [0.56 square meters]) are acceptable.
The dryer mustbe installed with provisions for adequate combustion and make-up air supply.
Allowances must be made for remote or constricting passageways or where dryers are located at excessive
altitudes or predominantly low-pressure areas.
IMPORTANT: Make-up airmustbe provided fromasource freeofdry cleaningsolventfumes.
Make-upairthatiscontaminatedbydrycleaningsolventfumeswillresultin
irreparable damagetothemotorsand other dryer components.
IMPORTANT: Make-up air openingsshouldnotbelocated near ductwork exhaust outlets. If
make-upair openings are toocloseto the exhaust outlet,lint andfumesmaybedrawn
backintothedryerarea through these openings.
NOTE: Componentfailure due to dry cleaningsolvent fumeswillVOID THEWARRANTY.

113203-3 Maytag 11
E. EXHAUST REQUIREMENTS
Exhaust ductwork should bedesigned and installed by a qualified professional. Improperly sized ductworkwill
create excessive back pressure, which results in slow drying, increased use of energy, overheating of the dryer,
and shut down of the burner by the airflow (sail) switches, burner hi-limits, or basket (tumbler) hi-heatthermostats.
The dryer must be installed with a proper exhaust duct connection to the outside.
CAUTION: This dryer produces combustible lint andmustbeexhaustedtotheoutdoors.
CAUTION: IMPROPERLY SIZEDOR INSTALLED EXHAUSTDUCTWORK CAN
CREATE APOTENTIAL FIREHAZARD.
The exhaust ductwork should belaid out in such a way that the ductwork travels as directly as possible to the
outdoors with as few turns as possible. When single dryer 10-inch (25.4 cm) vertical venting is used, the
ductwork from the dryer to the outside exhaust outlet must not exceed 35 feet (10.67 meters) or for 10-inch
(25.4 cm) horizontal venting, must not exceed 10 feet (3.05 meters). In the case of multiple (common) dryer
venting, the distance from the last dryer to the outside exhaust outlet must not exceed 15 feet (4.57 meters).
The shape of the exhaust ductwork is not critical as long as the minimum cross-sectional area is provided.
It is suggested that the use of 90º turns in ducting be avoided; use 30º or 45º angles instead. Excluding basket
(tumbler)/dryer elbow connections or elbows used for outside protection from the weather, no more than two (2)
elbows should beused in the exhaust duct run. If more than two (2) elbows are used, the cross section area of
the ductwork must be increased in proportion to the number of elbows added.
1. Exhaust Connections of Top and Bottom Baskets (Tumblers)
There is no common venting connection provided with the dryer. Each basket (tumbler) exhaust duct is
provided with its own back draft damper. Each basket (tumbler) can be exhausted directly outdoors
independently or connected to a common duct. Both single and common ductwork can be rigid ducting or
flexible ducting. Forcommon connections, a kit (P/N 882035) is available from the factory and includes the
necessary flex ducting, elbows, and “Y” assembly, etc., to join the top and bottom exhausts together.
ALL ductwork joints must be taped to prevent moisture and lint from escaping into the building.
IMPORTANT: Exhaustbackpressuremeasured by a manometer ateachbasket(tumbler)exhaust
duct areamust beno less than 0 andmust notexceed 0.3inches (0.74 mb)water
column(W.C.)whenbothbaskets(tumblers)areoperating.
NOTE: Commonexhaustconnectionsoftopandbottombaskets(tumblers)shouldbeinstalledin
suchamannerthatthebackguardscanberemovedeasilyforservicing.
IMPORTANT: Itis recommended that exhaust or booster fans NOT BE USEDin the exhaust
ductworksystem.
NOTE: Asperthe NationalFuelGasCode,“Exhaust ductsforType2clothes dryersshallbe

instrength andcorrosionresistancetoductsmadeofgalvanizedsheetsteel notlessthan26
gauge(0.0195-inches[0.05 mm]) thick.”

12 Maytag 113203-3
2. Single Dryer Venting
Where possible, it is suggested to provide a separate exhaust duct for each dryer. The exhaust ductwork
should be laid out in such a way that the ductwork travels as directly as possible to the outdoors with as
few turns as possible. It is suggested that the use of 90º turns in ducting be avoided; use 30º or 45º angles
instead. The shape of the exhaust ductwork is not critical as long as the minimum cross-sectional area is
provided.
NOTE: Exhaustbackpressuremeasuredbyamanometer at the dryer exhaust duct area must beno
less than 0 andmust not exceed0.3inches (0.74 mb) watercolumn(W.C.).
It is suggested that the ductwork from each dryer not exceed the limitations noted in this manual. If the
ductwork exceeds these limitations or has numerouselbows, the cross-sectional area of the ductworkmust
be increased in proportion to length or number of elbowsinit.
IMPORTANT: Forextendedductworkruns,thecross-sectionalarea oftheductworkcanonlybe
increasedtoanextent. Whentheductworkapproachesthemaximumlimitsasnoted
inthismanual,aprofessionalheating,ventilating,andair-conditioning(HVAC)firm
should beconsultedforproperventinginformation.
The ductwork should besmooth inside with no projections from sheet metal screws or other obstructions,
which will collect lint. When adding ducts, the duct to be added should overlap the duct to which it is to be
connected. ALL ductwork joints must be taped to prevent moisture and lint from escaping into the
building. Also,inspection doorsshould beinstalled at strategic points in the exhaust ductwork for periodic
inspection andcleaning.
NOTE: Whentheexhaust ductwork passesthroughawall,ceiling, or roofmadeofcombustible
materials, the openingmust be 2-inches(5.08cm)largerthantheduct(allthewayaround).
The duct mustbecenteredwithinthisopening.
To protect the outside end of the horizontal ductwork from the weather, a 90º elbow bent downwardshould
be installed where the exhaust exits the building. If the exhaust ductwork travels vertically up through the
roof, it should be protected from the weather by using a 180º turn to point the opening downward. In
either case, allowat least twice the diameter of the duct between the duct opening and nearest obstruction.
IMPORTANT: DO NOTusescreens, louvers, or caps on the outside opening of the exhaust
ductwork.
NOTE: Refer to the illustrationson page 13 andpage 14 forexamplesof singledryerventing.

113203-3 Maytag 15
3. Multiple Dryer (Common) Venting
If it is not feasible to provide separate exhaust ducts for each dryer, ducts from individual dryers may be
channeled into a “common main duct.” The individual ducts should enter the bottom or side of the main
duct at an angle not more than 45º in the direction of airflow. The main duct should be tapered, with the
diameter increasing before each individual 10-inch (25.4 cm) duct (when dryer common exhaust is used) is
added. If single 6-inch (15.24 cm) basket (tumbler) exhaust ducts are used, the diameter should be
increased after every second 6-inch (15.24 cm) duct.
IMPORTANT: Nomorethan four (4) dryersoreight(8)baskets(tumblers) total shouldbe
connectedtoone(1)maincommonduct.
NOTE: Refer to the illustrationson page 17forexamples ofmultipledryer(common) venting.
The main duct may be any shape or cross-sectional area as long as the minimum cross-sectional area is
provided. Theillustrations on page 17 show the minimum cross-sectional area for multiple dryer venting.
These figures must beincreased in proportion if the main duct run from the last dryer to where it exhausts
to the outdoors isunusually long (over 15 feet [4.57 meters]) or has numerous elbows (more than one [1])
in it. In calculating ductwork size, the cross-sectional area of a square or rectangular duct must be
increased twenty percent (20%) for each additional 15 feet (4.57 meters). The diameter of a round
exhaust must be increased ten percent (10%) for each additional 15 feet (4.57 meters).
IMPORTANT: Forextendedductworkruns,thecross-sectionalarea oftheductworkcanonlybe
increasedto an extent. Maximum proportional ductworkruncannot exceed 15feet
(4.57meters) morethantheoriginallimitationsof15 feet(4.57meters)withtwo(2)
elbows. Whenthe ductworkapproachesthemaximumlimitsasnotedinthismanual,
aprofessionalheating,ventilating,andair-conditioning(HVAC) firmshouldbe
