EXHAUSTING THE DRYER (cont.)
• DO NOT bend
or collapse
ducting. Use
elbows if turns
are necessary.
EXHAUST LENGTH
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 on the
chart.
• Internal elbows added for side or bottom vent
conversions must be included in the total elbow count.
• Any elbow greater than 45° should be treated as a 90°
elbow; one elbow of 45° or less may be ignored.
• Two 45° elbows will be treated like one 90° elbow.
• For the side exhaust installations, add one 90° elbow to
the chart.
• For every additional 90° elbow, reduce the allowable vent
system length by 10 feet.
• When calculating the total vent system length, you must
add all the straight portions and elbows of the system
(including the transition duct).
