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 cause increased
lint accumulation.
Lint accumulation
should be cleaned
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. 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.
Only a rigid or flexible
metal duct should be used for exhausting.
Keep the exhaust
duct as straight and short as possible.
Secure joints with duct tape. Do not use screws.
DO NOT EXHAUST
DRYER INTO ANY 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 LINT EXPELLED BY THE DRYER.
A 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
operation,
and
may collect lint.
The exhaust
duct should end with an exhaust hood that has a swing-out
damper to prevent back drafts
and the 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 exhaust ductwork
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 be sure the exhaust hood damper
opens and closes freely.
Check the duct once per month,
and clean at least one time per year. Note: If clothes are not getting
dry, then check ducting
for obstructions.
