Exhaust system requirements
Use only 4 inch (10.2 cm) diameter (minimum) rigid
or flexible metal duct and approved vent hood which
has a swing-out damper(s) that open when the dryer
is in operation. When the dryer stops, the dampers
automatically close to prevent drafts and the entrance
of insects and rodents. To avoid restricting the outlet,
maintain a minimum of 12 inches (30.5 cm) clearance
between the vent hood and the ground or any other
obstruction.
FIRE HAZARD
Failure to follow these instructions can create excessive _
drying times and fire hazards.
The following are specific requirements for
proper and safe operation of your dryer.
FIRE HAZARD
Do not install a clothes dryer with flexible plastic or
metal foil venting materials. Flexible venting materials
are known to collapse, be easily crushed and trap lint.
These conditions will obstruct clothes dryer airflow and
increase the risk of fire.
If your present system is made up of plastic duct or
metal foil duct, replace it with a rigid or semi-rigid metal
duct. In Canada and the United States if metal (foil type)
duct is installed, it must be of a specific type identified
by the appliance manufacturer as suitable for use with
clothes dryers and in the United States must also comply
with the Outline for Clothes Dryer Transition Duct, UL
standard 2158A. Also, ensure the present duct is free of
any lint prior to installing dryer duct.
