Routing and Connecting Ductwork
NOTE
Follow the guidelines below to maximize drying
performance and reduce lint buildup and
condensation in the ductwork.
Ductwork and fittings are NOT included and must be
purchased separately.
• Use 4-inch (10.2 cm) diameter rigid, semi-rigid, or
flexible metal ductwork.
• The exhaust duct run should be as short as possible.
• Use as few elbow joints as possible.
• The male end of each section of exhaust duct must
point away from the dryer.
• Use duct tape on all duct joints.
• Insulate ductwork that runs through unheated areas
in order to reduce condensation and lint buildup on
duct surfaces.
• Incorrect or inadequate exhaust systems are not
covered by the dryer warranty. Failures or poor
performance caused by such exhaust systems will
not be covered by the dryer warranty.
