EXAMPLE: For a bank of four 60 Hz dryers, two unrestricted
openings measuring 14-inches by 19-inches (35.6 cm by
48.3 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.
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.”
A = 14-inches (35.6 cm)
B = 19-inches (48.3 cm)
Dryer Enclosure Requirements _______
A The requirement to allow the door to open completely is
40-inches (101.6 cm).
B A minimum overhead clearance of 6-inches (15.24 cm)
is required.
C Dryer should be positioned a minimum of 12-inches
(30.48 cm) away from the nearest obstruction.
24-inches (60.96 cm) is recommended for ease of
installation, maintenance, and service.
D 1/16” (1.5875 mm) minimum is required.
E Flooring should be level or below dryer cabinet for ease
of removing panels during maintenance.
F Dryers may be positioned sidewall to sidewall, however
a 1/16” (1.5875 mm) minimum allowance must be made
for the opening and closing of the control door, as well
as for the removal of panels during maintenance.
Fresh Air Supply Requirements _______
hen 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 certain consideration
to ensure proper performance of each dryer. Fresh air
ventilation openings shall not be blocked and/or sealed. As
a general rule, an unrestricted air entrance from the outdoors
of 130 inch2 (838 cm2) is required for each dryer operating
at 60 Hz. (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.
112204- 2 Maytag Co. 9
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. hen adding
ducts, overlap the duct being connected. All ductwork joints
must be taped to prevent moisture and lint from escaping
into the building. This unit is fitted with an integral back
draft damper (inside the 8-inch [20.32 cm] exhaust
connection). 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. 8 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.
The ductwork for this dryer must be suitable for the appliance
category in accordance with national installation regulations
of the country of destination.
Outside Venting Protection
To shelter 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.
Fire Hazard
Use a heavy metal vent.
Do not use a lastic vent.
Do not use a metal foil vent.
Failure to follow these instructions can result in
death or fire.

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.
IMPORTANT: To maintain proper performance, no more
than dryers should be connected to 1 main common
duct.
The illustration below shows the minimum cross-sectional
area for multiple dryer round or square venting. These figures
must be increased if the main duct run from the last dryer to
where it exhausts to the outdoors is longer than 20 feet (6.1
meters) or has more than 1 elbow in it.
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.
