WARNING-
USE ONLY
METAL
4-IN. DUCT.
DO NOT USE DUCT
LONGER
THAN
SPECIFIED
IN THE EXHAUST
LENGTH
TABLE.
Using exhaust longer than specified length will:
• Increase the drying times and the energy cost.
• Reduce the dryer life.
" Accumulate
lint, creating a potential fire hazard.
The correct
exhaust
installation
is YOUR RESPONSIBILITY.
Problems due to incorrect
installation
are not covered
by the warranty.
The MAXIMUM
ALLOWABLE
length of the exhaust system
depends upon the type of duct, number of turns, the type of
exhaust hood (wall cap), and all conditions
noted below. Both
rigid and flexible metal duct are shown in the table below.

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 maintenance to prevent clogging.
• Never installa screen in or over the exhaust duct. Thiscould cause lintbuild up.
, Wall caps must be installed at least 12 in. 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-in. dampened wall cap in regard to resistance to air flow, prevention of
back drafts, and maintenance required to prevent clogging.
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 90°
• One turn of 45 ° or less may be ignored.
• Two 45 ° turns should be treated as one 90 ° turn.
"Each turn over 45 o should be treated as one 90° turn.
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.
• Do not assemble the ductwork with fasteners that extend into the duct.
They will serve as a collection point for 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 1/2 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.
