Dryer Exhaust Requirements . . .
Never install flexible duct in concealed spaces, such as
a wall or ceiling.
Exhaust System Materials
Exhaust duct must be four inches (10.2 cm) in diameter
having no obstructions. Rigid metal duct is
recommended. Non-combustible semi-rigid flexible
metal duct is acceptable. Do not use plastic pipe or
flexible plastic pipe, because it contributes to poor
drying performance and collects lint, which can lead to
a fire hazard.
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.
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.
A clothes dryer produces combustible lint.
To reduce the risk of fire and combustion
gas accumulation the dryer MUST be
exhausted to the outdoors.
