The dryer must be installed with adequate clearance for air
openings into the combustion chamber.
Caution
This dryer produces combustible lint and must be
exhausted to the outdoors. Every 6 months,
inspect the exhaust ducting and remove any lint buildup.
Important
The dryer must be installed in a location/
environment, which the ambient temperature
remains between 40° F (4.44° C) and 130° F (54.44° C).
Unpacking/Setting Up__________________
Remove protective shipping material (i.e., plastic wrap and
optional shipping box) from the dryer.
Important
Dryer must be transported and handled in an
upright position at all times.
The dryer can be moved to its final location while still attached
to the skid or with the skid removed. To remove the skid from
the dryer, locate and remove the 2 bolts securing the base of
the dryer to the wooden skid. One is located at the center
rear and the other is at the center front.
With the skid removed, use caution and assure all four
leveling legs are fully retracted if the dryer is to be slid into its
final position.
Leveling Dryer
The dryer is equipped with 4 leveling legs, 1 at each corner of
the base. For optimum performance the dryer should be
level front-to-back and side-to-side.
Dryer Enclosure Requirements________
Bulkheads and partitions should be made of noncombustible
material.
Note
Allowances must be made for opening the control

113413-1 Telephone: [phone]
Fresh Air Supply Requirements________
When the dryer is operating, it draws in room air, heats it,
passes this air through the tumbler, and exhausts it out of the
building. Therefore, the room air must be continually
replenished from the outdoors. If the make-up air is
inadequate, drying time and drying efficiency will be adversely
affected. Ignition problems and sail switch “fluttering”
problems may result, as well as premature motor failure from
overheating. The dryer must be installed with provisions for
adequate combustion and make-up air supply.
Air supply (make-up air) must be given careful consideration
to ensure proper performance of each dryer. As a general
rule, an unrestricted air entrance from the outdoors of 110
inch2(710 cm2) is required for each MLG33 and 80 inch2
(516 cm2) for each SL2020 . (Based on 1 inch2[6.5 cm2] per
1,000 Btu [252 kcal].)
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-up air is distributed equally to all the dryers.
A = 14-inches (35.56 cm) B = 16-inches (40.64 cm)
EXAMPLE: For a bank of 4 MLG33 dryers, 2 unrestricted
openings measuring 14-inches by 16-inches (35.56 cm by
40.64 cm) are acceptable.
To compensate for the use of registers or louvers used over
the openings, this area must be increased by approximately
33%. Make-up air openings should not be located in an area
directly near where exhaust vents exit the building.
Allowances must be made for remote or constricting
passageways or where dryers are located at high altitudes
or predominantly low pressure areas.
Important
Make-up air must be free of dry cleaning solvent
fumes. Make-up air that is contaminated by dry
cleaning solvent fumes will result in irreparable damage to
the motors and other dryer components.
Note
Component failure due to dry cleaning solvent
fumes will void the warranty.
!
!
Exhaust Requirements________________
Exhaust ductwork should be designed and installed by a
qualified professional. Improperly sized ductwork will create
excessive back pressure, which results in slow drying,
increased use of energy, and shutdown of the burner by the
airflow (sail) switch, burner hi-limits, or lint chamber hi-limit
protector thermostat. The dryer must be installed with a proper
exhaust duct connection to the outside.
Caution
This dryer produces combustible lint and must be
exhausted to the outdoors.
Improperly sized or installed exhaust ductwork can create
a potential fire hazard.
The 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. There should be a minimum
6-inch (15.24 cm) clearance between the back guard and the
first bend in the ductwork for ease of servicing. Single or
independent dryer venting is recommended. It is suggested
that the use of 90° turns be avoided; use 30° and/or 45°
bends instead. The radius of the elbows should preferably
be 1-1/2 times the diameter of the duct. All ductwork should
be smooth inside with no projections from sheet metal
screws or other obstructions, which will collect lint. When
adding ducts, overlap the duct being connected. All ductwork
joints must be taped to prevent moisture and lint from
escaping into the building. Back draft dampers must be
installed in all commonly ducted systems. Inspection doors
should be installed at strategic points in the exhaust ductwork
for periodic inspection and cleaning of lint from the ductwork.
Important
It is recommended that exhaust or booster fans
not be used in the exhaust ductwork system.
Exhaust back pressure measured by a manometer/
magnehelic in the exhaust duct must be no less than 0 and
must not exceed 0.6 in WC (1.48 mb).
Note
When the exhaust ductwork passes through a wall,
ceiling, or roof made of combustible materials, the
opening must be 2-inches (5.08 cm) larger than the duct
(all the way around). The duct must be centered within this
opening.
As per the National Fuel Gas Code, “Exhaust ducts for type
2 clothes dryers shall be constructed of sheet metal or
other noncombustible material. Such ducts shall be
equivalent in strength and corrosion resistance to ducts
made of galvanized sheet steel not less than 26 gauge
(0.0195-inches [0.50 mm]) thick.”
The ductwork for this appliance must be suitable for the
appliance category in accordance with national installation
regulations of the country of destination.
!
!
!

12 Maytag Co. 113413-1
!
Outside Ductwork Protection
To protect the outside end of the horizontal ductwork from the
weather, a 90° elbow bent downward should be installed
where the exhaust exits the building. If the ductwork travels
vertically up through the roof, it should be protected from the
weather by using a 180° turn to point the opening downward.
In either case, allow at least twice the diameter of the duct
between the duct opening and the nearest obstruction (refer
to the diagram).
Important
Do not use screens, louvers, or caps on the
outside opening of the exhaust ductwork.
Single Dryer Venting
Important
For extended ductwork runs, the cross-sectional
area of the ductwork can only be increased to an
extent. When the ductwork approaches the maximum
limits as noted in this manual, a professional HVAC firm
should be consulted for proper venting information.
!
!
NOTE 1 Opening from combustible materials must be 2-inches (5.08 cm)
larger than the duct (all the way around). The duct must be centered
within this opening.
NOTE 2 Distance should be 2 times the diameter of the duct to the nearest
obstruction.
A = SL2020 - 20 feet (6.10 meters)
MLG33 - 12 feet (3.66 meters)
B = 8-inches (20.32 cm)
Thelengthof the ductwork from the dryer totheoutsideexhaust
outlet, must not exceed 12 feet (3.66 meters) for the MLG33
. The minimum
diameter of this ductwork must be at least 8-inches (20.32
cm) even though the dryer exhaust duct connection is smaller.
Including tumbler/dryer elbow connections or elbows used
for outside protection from the weather, no more than 4 90°
elbows should be used in the exhaust duct run. If more than
the equivalent of 4 90° elbows are used, the cross-sectional
area of the ductwork must be increased.
Multiple Dryer (Common) Venting
Important
For extended ductwork runs, the cross-sectional
area of the ductwork can only be increased to an
extent. When the ductwork approaches the maximum
limits as noted in this manual, a professional HVAC firm
should be consulted for proper venting information.
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 duct is
added. The minimum diameter of the individual ductwork
must be at least 8-inches (20.32 cm).
