A = 6-inches (15.24 cm)

 B = 24-inches (60.96 cm)

EXAMPLE: For MDG51, 2 unrestricted openings measuring
6-inches by 24-inches (15.24 cm by 60.96 cm) are acceptable.
If a closet door is installed: unobstructed air openings are
required.  The air openings shall be located 3-inches
(7.62 cm) from the lower opening (above floor level) and upper
opening (below ceiling).  The total free area of the air openings
in the door shall not be less than  130 inch

 (1154.836 cm

(1890.319 cm

) for MDG51.  Louvered doors with equivalent

air openings are acceptable.
No other fuel-burning appliance shall be installed in the same
closet as the dryer.

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
inch

 (710 cm

] 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.
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.

Note

Component failure due to dry cleaning solvent
fumes will void the warranty.

A = 10-inches (25.4 cm)

 B = 11-inches (27.94 cm)

EXAMPLE: For a bank of 4 MDG31 dryers, 2 unrestricted
openings measuring 10-inches by 11-inches (25.4 cm by
27.94 cm) are acceptable.

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.

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.
The dryer shall not be exhausted into any gas vent, chimney,
wall, ceiling or concealed space of a building.

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.
