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 the chart below. (Check
with dryer unit 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 unit, see illustration below.
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.
Reduced Clearance Elbow
Installing the dryer unit in shallow closets can be
accomplished by using an Elbow, Part No. 62688, which
is one inch narrower than a standard venting elbow.
To reduce the risk of electric shock,
disconnect the electrical service to the dryer
before cleaning.
