3 Dryer Duct Length
Calculating the maximum allowable length for 4" (100 mm) ducting
When using 4" ducting, adequate air extraction is possible for an effective
duct length of up to 66 ft. (792 in.).
To calculate the effective duct length, proceed as follows:
A) Measure the total length of the proposed ducting, including any bends.
B) Determine the amount, angle, and type of bends that will be required.
C) Determine what type of fitting will be used to terminate the duct at the
outer wall (flap vent, louvered vent, grill, etc.).
D) Using the chart below, add the additional length factor of the bends and
fittings that will be used to the total length measured in Step A above. If
the sum is less than 66 ft. (792 inches), the appliance will be able to
