EXHAUST SYSTEM
REQUIREMENTS
Installation Instructions
Use only 4″ (10.2 cm) diameter (minimum) rigid metal
duct for best performance, or flexible metal duct, and
approved vent hood which has swing-out dampers 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″ (30.5 cm) clearance
between the vent hood and the ground or any other
obstruction.
If all rigid metal duct cannot be used, then flexible all-
metal venting can be used, but it will reduce the maximum
recommended duct length. See Additional Installation
Instructions following.
WARNING
–
The following are specific
requirements for proper and safe operation
of your dryer. Failure to follow these instructions can
create excessive drying times and fire hazards.
DO NOT use plastic flexible duct to exhaust the dryer.
Excessive lint can build up inside exhaust system and create
a fire hazard and restrict air flow. Restricted air flow will
increase drying times. If your present system is made up of
plastic duct or metal foil duct, replace it with rigid or flexible
metal duct. Ensure the present duct is free of any lint prior
to installing dryer duct.
If the dryer is not exhausted outdoors, some fine lint will be
expelled into the laundry area. An accumulation of lint in
any area of the home can create a health and fire hazard.
This dryer exhaust system MUST BE EXHAUSTED TO
THE OUTSIDE of the dwelling.
DO NOT allow combustible materials (for example:
clothing, draperies/curtains, paper) to come in contact with
exhaust system.

WARNING
The dryer MUST NOT be exhausted into a chimney,
a wall, a ceiling, a common duct with a kitchen exhaust or
any concealed space of a building which can accumulate
lint, resulting in a fire hazard.
DO NOT exceed the length of duct pipe or number of
elbows allowed in the Maximum Length charts. Lint can
accumulate in the exhaust system, plugging the system and
creating a fire hazard, as well as increasing drying times.
DO NOT screen the exhaust ends of the vent system, or
use any screws or rivets to assemble the exhaust system.
Lint can become caught in the screen, on the screws or
rivets, clogging the duct work and creating a fire hazard as
well as increasing drying times. Use an approved vent hood
to terminate the duct outdoors, and seal all joints with duct
tape. All male duct pipe fittings MUST be installed
downstream with the flow of air.
EXPLOSION HAZARD. Do not install the dryer where
gasoline or other flammables are kept or stored. If the
dryer is installed in a garage, it must be a minimum of 18″
(45.7 cm) above the floor. Failure to do so can result in
death, explosion, fire or burns.
ADDITIONAL INSTALLATION
INSTRUCTIONS
If all rigid metal duct cannot be used, then flexible all-
metal venting can be used, but it will reduce the maximum
recommended duct length. In special installations when it
is impossible to make a connection with the above
recommendations, then UL-listed clothes dryer transition
duct may be used as transition venting between the dryer
and wall connection only. The use of this ducting will affect
drying time.
If flexible transition duct is necessary, only UL-listed duct
identified for use with clothes dryers is approved.
The following directions must be followed.
• Use the shortest length possible.
• Stretch the duct to its maximum length.
• Do not crush or collapse.
• Never use transition duct inside the wall or inside the
dryer.
• Avoid resting the duct on sharp objects.
• Venting must conform to local building codes.
