Exhaust System Maintenance
The dryer unit interior and the complete exhaust
system should be inspected after one year of use and
cleaned if necessary. Inspect and clean exhaust duct
every one to two years as required thereafter. The
weather hood should be checked frequently to make
sure the dampers move freely, dampers are not pushed
in and that nothing has been set against them. This
maintenance work should be done by a qualified
service person.
Exhausting the dryer unit in hard-to-reach locations
can be accomplished by installing the 521P3 Flexible
Metal Vent Kit, available as optional equipment at
extra cost. The kit comes in two halves that can be
separately attached to the dryer unit, the wall outlet
and to each other. Once attached, the dryer can be slid
back into position.
Dryer Airflow
Efficient dryer unit operation requires proper dryer
airflow. Proper dryer unit airflow can be evaluated by
measuring the static pressure.
Static pressure in the dryer unit’s exhaust duct should
be no greater than that shown in Figure 24. (Check
with dryer unit running and no load.)
NOTE: This can be measured with a manometer
placed on the exhaust duct approximately 2 feet
(61 cm) from the dryer unit. Refer to Figure 24.

IMPORTANT: DO NOT block the airflow at the
bottom of the dryer unit’s front panel with laundry,
rugs, etc. Blockage will decrease airflow through
the dryer unit, thus reducing the efficiency of the
dryer unit.
To reduce the risk of electric shock,
disconnect the electrical service to the
dryer before cleaning.
