Dryer Exhaust Requirements
Figure 14
Exhaust System Materials
Exhaust duct must be 10.2 cm (4 inches) in diameter
having no obstructions. Rigid metal duct is
recommended. Non-combustible flexible metal duct is
acceptable. Do not use plastic or thin foil ducting,
because it contributes to poor drying performance and
collects lint, which can lead to a fire hazard.
Never install flexible duct in concealed spaces, such as
a wall or ceiling.
DO NOT use sheet metal screws on exhaust pipe joints
or other fastening means which extend into the duct
that could catch lint and reduce the efficiency of the
exhaust system. Secure all joints with duct tape or
pop-rivets.
Make-Up Air Requirements
For proper operation it is important that you locate the
dryer in an area that has an ample amount of make-up
air to replace the amount exhausted by the dryer.
Energy efficient homes with low air infiltration rates
should be equipped with an air exchanger that can
accommodate on demand make-up air needs in the
home. These devices can be obtained through your
building contractor or building material suppliers.
Exhaust System
IMPORTANT: Keep exhaust duct as short as
possible.
NOTE: Be certain old ducts are cleaned before
installing your new dryer.
For best drying results, recommended maximum
length of exhaust system is shown in Table 3.
To prevent backdraft when dryer is not in operation,
outer end of exhaust pipe must have a weather hood
with hinged dampers (obtain locally).
NOTE: Weather hood should be installed at least
30.5 cm (12 inches) above the ground. Larger
clearances may be necessary for installations where
heavy snowfall can occur.
D314I D315I
A clothes dryer produces combustible lint.
To reduce the risk of fire and combustion
gas accumulation the dryer MUST be
exhausted to the outdoors.
W116
To reduce the risk of fire and the
accumulation of combustion gases, DO NOT
exhaust dryer air into a window well, gas
vent, chimney or enclosed, unventilated
area, such as an attic, wall, ceiling, crawl
space under a building or concealed space
of a building.
W045
To reduce the risk of fire, DO NOT use
plastic or thin foil ducting to exhaust the
dryer.
