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 chart 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, see illustration below. 
Reduced Clearance Elbow
Installing the dryer 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.
