information.
WARNING
Fire Hazard

If the dryer is not properly installed and vented, it will not be

important for satisfactory drying results. See the Installation
Instructions for more detail.
NOTE: Service calls caused by improper venting will be paid for
by the customer, whether it was a paid installation or self-
installed.

Checking Your Vent

1. Do not use plastic vent or metal foil vent. Use 4" (102 mm)
metal or flexible metal vent. Do not kink or crush flexible metal
vent. It must be completely extended to allow adequate
exhaust air to flow. Check vent after installation. Refer to the
Installation Instructions for proper length requirements of vent.
2. Use a 4" (102 mm) exhaust hood.
3. Use the straightest path possible when routing the vent.
4. Use clamps to seal all joints. Do not use duct tape, screws, or
other fastening devices that extend into the interior of the vent
to secure vent, which can catch lint.
5. Clean exhaust vent periodically, depending on use, but at
least every 2 years, or when installing your dryer in a new
location. When cleaning is complete, be sure to follow the
Installation Instructions supplied with your dryer for final
product check.
