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-limit protector thermostat.  The dryer 

must

be

 installed with a proper exhaust duct connection to the outside.

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.

CAUTION:

DRYER 

MUST BE

 EXHAUSTED TO THE OUTDOORS.

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 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.

To 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.).
