DUCTING
REQUIREMENTS
•
Use a 4-inch
(10.2 cm) diameter
rigid aluminum
or rigid galvanized
steel duct.
•
Do not use a smaller duct.
•
Ducts larger than 4 inches (10.2 cm) in diameter
can result in increased
accumulation
of lint.
•
Lint should
be removed
regularly.
•
If a flexible
metal duct must be used, use the type with a stiff sheet metal wall. Do not use a flexible duct
with a thin foil wall. A serious blockage
can result if the flexible metal duct is bent too sharply.
•
Never install any type of flexible duct in walls, ceilings,
or other concealed
spaces.
•
Keep the exhaust duct as straight
and short as possible.
•
Secure joints with duct tape. Do not use screws.
•
Do not use plastic flexible duct. Plastic flexible duct can kink, sag, be punctured,
reduce airflow, extend
drying times, and affect dryer operation.
•
Exhaust
systems longer than recommended
can extend drying times, affect machine
operations,
and
collect lint.
•
The exhaust duct should end with an exhaust hood with a swing-out
damper to prevent back drafts and
entry of wildlife.
Never use an exhaust hood with a magnetic
damper.
•
The hood should have at least 12 inches (30.5 cm) of clearance
between
the bottom
of the hood and
the ground
or other obstruction.
The hood opening should
point down.
•
Never install a screen over the exhaust
outlet.
•
To avoid lint buildup,
do not exhaust the dryer directly into a window
well. Do not exhaust
under a house
or porch.
•
If the exhaust duct must run through
an unheated
area, the duct should be insulated and slope slightly
down towards
the exhaust hood to reduce condensation
and lint buildup.
•
Inspect
and clean the interior of the exhaust system at least once a year. Unplug the power cord before
cleaning.
•
Check frequently
to make sure the exhaust
hood damper
opens and closes freely.
•
Check once per month, and clean at least once per year. Note: If your clothes are not getting dry, then
check the ducting for obstructions.
•
Do not exhaust the dryer into a wall, ceiling, crawl space, or concealed
space of a building,
gas vent, or
any other common
duct or chimney. This could create a fire hazard from the lint expelled by the dryer.
