1. The dryer must be installed on a sound level floor capable of supporting its weight. Carpeting must be
removed from the floor area that the dryer is to rest on.
IMPORTANT: “The dryer must be installed on noncombustible floors only .”
2. The dryer must not be installed or stored in an area where it will be exposed to water and/or weather.
3. The dryer is for use in noncombustible locations.
4. Provisions for adequate air supply must be provided as noted in this manual (refer to Fresh Air Supply
Requirements in
5. Clearance provisions must be made from combustible construction as noted in this manual (refer to Dryer
Enclosure Requirements in Section C).
Section D).
6. Provisions must be made for adequate clearances for servicing and for operation as noted in this manual
(refer to Dryer Enclosure Requirements in Section C).
7. Dryer must be exhausted to the outdoors as noted in this manual (refer to Exhaust Requirements in
Section E).
8. Dryer must be located in an area where correct exhaust venting can be achieved as noted in this manual
(refer to Exhaust Requirements in Section E).
IMPORTANT: Dryer should be located where a minimum amount of exhaust duct will be necessary .
9. The dryer must be installed with a proper exhaust duct connection to the outside.
10. The dryer must be installed with provisions for adequate combustion and make-up air supply.
CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors. Every 6
months, inspect the exhaust ducting and remove any lint build up.
9
C. DRYER ENCLOSURE REQUIREMENTS
Bulkheads and partitions should be made of noncombustible materials and must be located a minimum of
12-inches (30.48 cm) above the dryer’s outer top; except along the front of the dryer, which may be closed if
desired.
NOTE: Allowances must be made for opening the control door .
NOTE: With the exception of the floor , clearances shown are for combustible construction.
X = 12-inch (30.48 cm) minimum, 24-inches (60.96 cm) is suggested for ease of maintenance.
* 1-inch (2.54 cm) maximum for electric dryers.
NOTE: Air considerations are important for proper and efficient operation.
Dryers may be positioned sidewall to sidewall. However, a 1/16-inch (1.59 mm) minimum allowance must be
made for opening and closing of the control 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 above for details.
10
D. FRESH AIR SUPPLY REQUIREMENTS
The MDG30V air supply (make-up air) must be given careful consideration to assure proper performance of
each dryer. An unrestricted source of air is necessary for each dryer. As a general rule, 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. If registers or louvers are installed over the openings, then the area must be increased. It
necessary to have separate make-up air openings 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 the dryers. The
dryer must be installed with provisions for adequate combustion and make-up air supply.
EXAMPLE: For a bank of eight (8) dryers, two (2) unrestricted openings measuring 3 feet by 2 feet (0.914
meters by 0.61 meters) (6 square feet [0.557 square meters]) is acceptable.
is not
IMPORTANT: 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 excessive
altitudes or predominantly low pressure areas.
IMPORTANT: Make-up air must be provided from a source free of contaminating fumes such as 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.
11
E. 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.
Where possible, it is suggested to provide a separate (single) exhaust duct for each dryer.
CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors.
CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCTWORK CAN
CREA TE A POTENTIAL FIRE HAZARD.
CAUTION: DRYER MUST BE EXHAUSTED TO THE OUTDOORS.
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. The shape of the ductwork is not critical so long as the minimum cross
section area is provided. Single or independent dryer venting is recommended.
It is suggested that the use of 90° turns be avoided; use 30° or 45° angles instead.
The ductwork should be smooth inside with no projections from sheet metal screws or other obstructions,
which will collect lint. When adding ducts, the ducts to be added should overlap the duct to which it is connected.
ALL ductwork joints must be taped to prevent moisture and lint from escaping into the building. Additionally,
inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and
cleaning.
IMPORTANT: When connecting ductwork to the dryer exhaust duct, be sure that when screws are
used they DO NOT restrict the operation (both opening and closing) of the damper.
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.
T o 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 (i.e., roof or ground level).
IMPORTANT: DO NOT use screens, louvers, or caps on the outside opening of the exhaust
ductwork.
IMPORTANT: Exhaust back pressure measured by a manometer at the dryer exhaust duct area must
be no less than 0 and must not exceed 0.3 inches (0.74 mb) of water column
(W.C.).
