K Terminate in a manner to prevent back drafts
or entry of birds or other wildlife.
K Termination should present minimal resistance
to the exhaust airflow and should require little
or no maintenance to prevent clogging.
K #4E4A install a screen in or over the exhaust
duct. This could cause lint buildup.
K Wall caps must be installed at least 12″ above
ground level or any other obstruction with the
opening pointed down.

For best performance, separate all turns
by at least 4 ft. of straight duct, including
the distance between the last turn and

K One turn of 45º or less may be ignored.
K Two 45º turns should be treated as one
90º turn.
K Each turn over 45º should be treated as
one 90º turn.

K All joints should be tight to avoid leaks.
The male end of each section of duct must
point away from the dryer.
K Do not assemble the ductwork with fasteners
that extend into the duct. They will serve as
a collection point for lint.
K Duct joints can be made air- and moisture-tight
by wrapping the overlapped joints with duct
tape.
K Horizontal runs should slope down toward
the outdoors 1/2″ per foot.

Ductwork that runs through an unheated area
or is near air conditioning should be insulated
to reduce condensation and lint buildup.
