Installation Instructions

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.
< The duct shall not be assembled with screws or other
fastening means that extend into the duct and catch lint.
< Duct joints can be made air and moisture-tight by wrapping
the overlapped joints with duct tape.
< Horizontal runs should slope down toward the outdoors
1/4 inch per foot.
INSULATION
Duct work that runs through an unheated area or is near air
conditioning should be insulated to reduce
condensation and
lint build-up.
EXHAUST SYSTEM CHECK LIST
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
air flow and should require little or no maintenace to prevent clogging
<
Never install a screen in or over the exhaust duct. This could
cause lint build up.
<
Wall caps must be installed at least 12 in. above ground level
or any other obstruction with the opening pointed down.
SEPARATION OF TURNS
For best performance, separate all turns by at least 4 ft. of straight
duct, including distance between last turn and exhaust hood.
TURNS OTHER THAN 90º
< One turn of 45º or less may be ignored.
< Two 45º turns should be treated as one 90º turn.
< Each turn over 45º should be treated as one 90º turn.
