Step 7: Connect Dryer Exhaust System
•
DO NOT use plastic, thin foil or type B ducting.
Rigid metal duct is recommended. Refer to
Figure 21
.
•
Locate dryer so exhaust duct is as short as
possible.
•
Be certain old ducts are cleaned before installing
your new dryer.
•
Use 4 inch (102 mm) diameter rigid or flexible
metal duct.
•
The male end of each section of duct must point
away from the dryer.
•
Use as few elbows as possible.
•
Use of duct tape or pop-rivets on all seams and
joints is recommended, if allowed by local codes.
DO NOT use sheet metal screws or fasteners on
exhaust pipe joints which extend into the duct
and catch lint.
•
Ductwork that runs through unheated areas must
be insulated to help reduce condensation and lint
build-up on pipe walls.
•
In mobile home installations, dryer exhaust duct
must be secured to mobile home structure.
•
Dryer exhaust duct MUST NOT terminate under
mobile home.
•
Dryer exhausts 220 cfm (measured at back of
dryer).
•
DO NOT install flexible duct in concealed
spaces, such as a wall or ceiling.
•
Static pressure in exhaust duct should not be
greater than .6 inches water column (1.5 cm),
measured with manometer placed on exhaust
duct 2 feet (61 cm) from dryer (check with dryer
running and no load).
•
Exhausting dryer in hard-to-reach locations can
be done by installing 521P3 Flexible Metal Vent
Kit (available as optional equipment at extra
cost).
•
Sufficient make-up air must be supplied to
replace the air exhausted by the dryer. The free
area of any opening for outside air must be at
least 40 in.
2
(260 cm
2
).
•
Failure to exhaust dryer properly will void
warranty.
NOTE: Venting materials are not supplied with the
dryer (obtain locally).
IMPORTANT: DO NOT block the airflow at the
bottom of the dryer’s front panel with laundry,
rugs, etc. Blockage will decrease airflow through
the dryer, thus reducing the efficiency of the dryer.
