Installation Instructions
EXHAUSTING THE DRYER
EXHAUST SYSTEM CHECKLIST
HOOD OR WALL CAP
• Terminate in a manner to prevent back drafts or entry
of birds or other wildlife.
• Termination should present minimal resistance to
the exhaust airflow and should require little or no
maintenance to prevent clogging.
• Wall caps must be installed at least 12” above ground
level or any other obstruction with the opening
pointed down.
• Never vent the dryer out of the roof.
SEPARATION OF TURNS
• For best performance, separate all turns by at least
4 ft. of straight duct, including distance between last
turn and dampened wall cap.
SEALING OF JOINTS
• All joints should be tight to avoid leaks. The male end
of each section of duct must point away from the
dryer.
• Duct joints should be made air- and moisture-tight
by wrapping the overlapped joints with duct tape or
aluminum tape.
• Do not assemble ductwork with any fasteners
that extend into the duct. These fasteners can
accumulate lint, creating a potential fire hazard.
• Horizontal runs should slope down towards the
outdoors 1/4” per foot.
• Provide an access for inspection and cleaning of
the exhaust system, especially at turns and joints.
Exhaust system shall be inspected and cleaned at
least once a year.
INSULATION
• Ductwork that runs through an unheated area or is
near air conditioning should be insulated to reduce
condensation and lint buildup.
