Rigid metal vent:
■■ Recommended for best drying performance and to avoid crushing and kinking.
Flexible metal vent: (Acceptable only if accessible to clean) ■■ Must be fully extended and supported in final dryer location.
■■ Remove excess to avoid sagging and kinking that may result in reduced airflow and poor performance.
■■ Do not install in enclosed walls, ceilings, or floors. ■■ The total length should not exceed 73/4 ft. (2.4 m).
■■ The length of flexible metal vent used must be included in the overall vent system design as shown in the Vent System Chart.
NOTE: If using an existing vent system, clean lint from entire length of the system and make sure exhaust hood is not plugged with lint. Replace plastic or metal foil vents with rigid metal or flexible metal vents. Review Vent System Chart and if necessary, modify existing vent system to achieve best drying performance.
Clamps:
■■ Use clamps to seal all joints.
■■ Exhaust vent must not be connected or secured with screws
or other fastening devices that extend into interior of duct and catch lint. Do not use duct tape.
