hood (wall cap) and all conditions noted
below. The maximum allowable length for
both rigid and flexible metal is shown in the
table below. More than three 90 ° turns are
not recommended.

Hood or Wall Cap
• Terminate in a manner to prevent back
drafts or entry of birds or other wildlife.
• Termination should present minimal resist-
ance to the exhaust airflow and should
require little or no maintenance to prevent
clogging.
• Never install screen over exhaust duct.
• Will caps must be installed at least 12" above
ground level or any other obstruction with
the opening pointed down.
• If roof vents or louvered plenums are used,
they must be equivalent to a 4" dampered
wall cap in regard to resistance to airflow,
prevention of back drafts and maintenance
required to prevent clogging.
Turns Other Than 90°
• One turn of 45° or less may be ignored.
• Two 45 ° turns should be treated as one 90 °.
(continued)
Sealing of Joints
• All joints should be tight to avoid leaks.
NOTE: The male end of each section of duct
must point away from the dryer.
• Do not assemble ductwork with fasteners
that extend into the duct. They will service
as a collection point for lint.
• Duct joints can be made air and moisture-
tight by wrapping the overlapped joints with
duct tape.
Insulation
• Ductwork that runs through an unheated
area or is near an air conditioning duct,
should be insulated to reduce condensation
and lint build-up.
