Flexible metal vent must be fully extended and supported when the dryer is in its final location.
Remove excess flexible metal vent to avoid sagging and kinking that may result in reduced airflow and poor performance.
Do not install flexible metal vent in enclosed walls, ceilings or floors.

An exhaust hood should cap the vent to keep rodents and insects from entering the home.
Exhaust hood must be at least 12" (30.5 cm) from the ground or any object that may be in the path of the exhaust (such as flowers, rocks or bushes, snow line, etc.).
Do not use an exhaust hood with a magnetic latch.
