Exhaust Requirements

Individual Venting

For maximum efficiency and performance, it is
preferred to exhaust tumbler(s) individually to the
outdoors.
IMPORTANT: At no point may the cross sectional
area of installed venting be less than the cross
sectional area of the exhaust outlet of the tumbler.
The exhaust duct must be designed so the static back
pressure measured 12 inches (305 mm) from the
exhaust outlet does not exceed the maximum
allowable pressure specified on the installation sticker
on the rear of the tumbler. Static back pressure must be
measured with the tumbler running (both pockets on
stacked models).
The maximum allowable length venting of the same
diameter as the exhaust thimble is 14 feet (4.3 meters)
and two 90° elbows or equivalent. If the equivalent
length of a duct required for an installation exceeds the
maximum allowable equivalent length, the diameter of
a round duct must be increased by 10% for each
additional 20 feet (6.1 meters). Cross section area of a
rectangular duct must be increased by 20% for each
additional 20 feet (6.1 meters). Table 12 shows how to
determine equivalent venting.

larger than diameter of exhaust duct shall be provided, with exhaust duct centered in opening.

6 in. (152 mm)
8 in. (203 mm)
10 in. (254 mm)
12 in. (305 mm)
14 in. (355.6 mm)
16 in. (406.4 mm)
18 in. (457.2 mm)
Equivalent Length (feet) = 1.17 x Duct Diameter (inches)
Example: A 12 inch diameter duct's equivalent
length of 14 feet of duct and two 90° elbows is:
Equivalent Length = 14 feet + (2) 90° elbows
With the tumbler (both pockets on stacked models) in
operation, airflow at any point in the duct should be at
least 1200 feet per minute (366 meters per meter) to
ensure that lint remains airborne. If 1200 feet per
minute cannot be maintained, schedule a regular
inspection and cleaning of the ductwork.

One 90° elbow = 7 ft. (2.1 m)
One 90° elbow = 9.3 ft. (2.83 m)
One 90° elbow = 11.6 ft. (3.5 m)
One 90° elbow = 14 ft. (4.3 m)
One 90° elbow = 16 ft. (4.9 m)
One 90° elbow = 18.7 ft. (5.7 m)
One 90° elbow = 21 ft. (6.4 m)
