Exhaust System Maintenance
The dryer 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 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 and wall outlet. Once attached,
the dryer can be slid back into position and the two
halves can be connected from the front.

Dryer Airflow
Efficient dryer operation requires proper dryer airflow.
Proper dryer airflow can be evaluated by measuring
the static pressure.
Static pressure in the dryer’s exhaust duct should be no
greater than that shown in the illustration below.
(Check with dryer running and no load.)
NOTE: This can be measured with a manometer
placed on the exhaust duct approximately two feet
(61 cm) from the dryer. Refer to Figure 31.

disconnect the electrical service to the dryer
before cleaning.
