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-limit, or lint chamber hi-heat 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.
When possible, it is suggested to provide a separate (single) exhaust duct for each dryer.
CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCTWORK CAN
CREATE A POTENTIAL FIRE HAZARD.
IMPORTANT: It is recommended that exhaust or booster fans not be used in the exhaust
ductwork system.
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 as long as the minimum cross
section area is provided. Single or independent dryer venting is recommended.
It is suggested that the use of 90º turns be avoided; use 30º or 45º 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.
To protect the outside end of the horizontal ductwork from the weather, a 90º 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 180º 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.).
