Installation

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.

WARNING

To reduce the risk of electric shock, disconnect the electrical service to the dryer before cleaning.

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 unit can be slid back into position.

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 Figure 45. (Check with dryer running and no load.)

NOTE: This can be measured with a manometer placed on the exhaust duct approximately 2 ft. (61 cm) from the dryer. Refer to Figure 45.
