EXHAUSTING THE DRYER
EXHAUST SYSTEM CHECKLIST
HOOD OR WALL CAP
• Terminate in a manner to prevent back
drafts or entry of birds or other wildlife.
• Termination should present minimal
resistance to the exhaust airflow and
should require little or no maintenance
to prevent clogging.
• Never install a screen in or over the
exhaust duct.
• Wall caps must be installed at least 12”
above ground level or any other obstruction
with the opening pointed down.
SEPARATION OF TURNS
• For best performance, separate all turns by
at least 4 ft. of straight duct, including
distance between last turn and dampened
wall cap. For turns less than 4 ft. apart, see
the Ducting Component Equivalency Chart.
SEALING OF JOINTS
• All joints should be tight to avoid leaks.
The male end of each section of duct must
point away from the dryer.
• Do not assemble the ductwork with
fasteners that extend into the duct. They
will serve as a collection point for lint.
• Duct joints should be made air- and
moisture-tight by wrapping the overlapped
joints with duct tape or aluminum tape.
• Horizontal runs should slope down towards
outdoors 1/4” per foot.
INSULATION
• Ductwork that runs through an unheated
area or is near air conditioning should be
insulated to reduce condensation and lint
buildup.
WARNING – To reduce the
risk of fire or personal injury:
•
This clothes dryer must be exhausted to the
outdoors.
•
Use only 4
”
rigid metal ducting for the home
exhaust duct.
•
Use only 4
”
rigid metal or UL-listed flexible
metal (semi-rigid or foil-type) duct to connect
the dryer to the home exhaust duct. It must be
installed in accordance with the instructions
found in “Connecting the Dryer to House
Vent” on page 29 of this manual.
•
Do not terminate exhaust in a chimney, a wall,
a ceiling, gas vent, crawl space, attic, under
an enclosed floor, or in any other concealed
space of a building.
•
Never terminate the exhaust into a common
duct with a kitchen exhaust system. A
combination of grease and lint creates a
potential fire hazard.
•
Do not use duct longer than specified in the
exhaust length table. Longer ducts can
accumulate lint, creating a potential fire hazard.
•
Never install a screen in or over the exhaust
duct. This will cause lint to accumulate,
creating a potential fire hazard.
•
Do not assemble ductwork with any fasteners
that extend into the duct. These fasteners can
accumulate lint, creating a potential fire
hazard.
•
Do not obstruct incoming or exhausted air.
•
Provide an access for inspection and cleaning
of the exhaust system, especially at turns and
joints. Exhaust system shall be inspected and
cleaned at least once a year.
