10 American Dryer Corp. 113362 - 25
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-limit, or lint chamber hi-limit
protector thermostat. The dryer must be installed with a
proper exhaust duct connection to the outside.
The design of the flue system shall be such that any
condensate formed when operating the appliance from cold
shall either be retained and subsequently re-evaporated or
discharged.
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. 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, 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. Inspection
doors should be installed at strategic points in the exhaust
ductwork for periodic inspection and cleaning of lint from
the ductwork.
IMPORTANT: Exhaust back pressure measured by a
manometer/magnehelic in the exhaust duct must be no
less than 0 and must not exceed 0.3 in WC (0.74 mb).
NOTE: It is recommended that exhaust or booster fans
not be used in the exhaust ductwork system except where
necessary to maintain exhaust back pressure (in the
exhaust duct) between zero and 0.3 inch water column.
Where employed, booster fans must not activate the dryer
airflow proving switch (sail switch) when the dryer is not in
operation.
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.”
Fresh Air Supply Requirements ______
This appliance may only be installed in a room that meets
the appropriate ventilation requirements specified in the
national installation regulations.
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
(atmosphere) of a minimum of 2-1/2 feet
2
(0.2322576 meters
2
)
is required for each dryer. (Based on 1 inch 2 [6.4516 cm 2 ]
per 1,000 Btu [251.9958 kcal].)
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.
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.
EXAMPLE: For a bank of 4 dryers, 2 unrestricted openings
measuring 2 feet by 2-1/2 feet (0.61 meters by 0.762 meters)
are acceptable.
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 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.
