WARNING
USE ONLY METAL DUCT 4
″
DIAMETER (102 mm
FOR CANADA). DO NOT USE DUCT LONGER THAN
SPECIFIED IN THE EXHAUST LENGTH TABLE.
Ducting longer than 150 equivalent feet will:
• Increase the drying times and the energy cost.
• Reduce the dryer life.
• Accumulate lint, creating a potential fire hazard.
• Total length of flexible metal duct should not
exceed 7.9
′
(2.4 m).
EXAMPLE ONLY
The following chart describes an example of one
possible ductwork installation.
The correct exhaust installation is your
responsibility.
Problems due to incorrect installation are not
covered by the warranty.
The length of the exhaust system depends upon
the type of duct, number of turns and the type of
exhaust hood (wall cap), and all conditions noted
below. Both rigid and flexible metal ducts are shown
in the table.
For satisfactory air movement, the total duct length
should not exceed 150 equivalent feet.
