EXHAUSTING THE DRYER (cont.)
-A WARNING
USE ONLY METAL 4" DUCT. 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.
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.
