Before installing the exhaust system, be sure to remove the wire exhaust guard that is located at the exhaust outlet.
Use duct tape to seal all joints. Do not use screws to secure vent. Lint may catch on screws.
Use 4 inch heavy metal vent. Do not kink or crush flexible metal vent. It must be fully extended to allow adequate exhaust air to flow. Check vent after installation.

Exhaust airflow
Use the straightest path possible when routing the exhaust vent. Use the fewest number of elbows and turns. Allow as much room as possible when using elbows or making turns. Bend vent gradually to avoid kinking. Remove excess flexible vent to avoid sagging and kinking that may result in reduced airflow.
Maximum length of the exhaust system depends upon the type of vent used, number of elbows, and the type of exhaust hood. The maximum length for both heavy and flexible vent is shown on the next page. Exhaust outlet at rear of dryer is located as illustrated. Detailed instructions on spacing for side and rear clearances can be found in the “Recessed area and closet installation” section.
