EXHAUST CONTINUED
Never install any type of flexible duct in walls, ceilings or other
concealed spaces. Keep exhaust duct as straight and short as
possible. Exhaust systems longer than recommended can extend
drying times, affect machine operation and may collect lint. Secure
joints with duct tape. Do not use screws.
The exhaust duct should end with an exhaust hood with a swing
out damper to prevent backdrafts 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.
When possible, do not exhaust the dryer directly into a window well
in order to avoid lint build-up. 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 build-up.
If an existing exhaust system is to be used with your new dryer,
you must be sure:
• The exhaust system meets all local, state and national codes.
• That plastic flexible duct is not used.
• To completely inspect and clean all lint accumulation from the
interior of the duct.
• The duct is not kinked or crushed.
• The exhaust hood damper opens and closes freely.
The static pressure in any exhaust system must not exceed 0.92
inches of water column, or be less than 0. This can be measured
with the dryer running with a manometer at the point where the
exhaust duct connects to the dryer. A no heat setting should be
used. The dryer tumbler should be empty and the lint filter clean
Inspect and clean the interior or the exhaust system at least once a
year. Disconnect electrical service prior to cleaning. Check the gas
line on gas dryers anytime the dryer is moved. Frequently check to
be sure the exhaust hood damper opens and closes freely.
W A R N I N G
THE DRYER MUST BE EXHAUSTED TO THE
OUTSIDE TO REDUCE THE RISK OF FIRE WHEN
INSTALLED.
W A R N I N G
DO NOT EXHAUST DRYER INTO ANY WALL,
CEILING, CRAWL SPACE, 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.
