RECOMMENDATIONS

Nothing is more important than air flow for the proper operation of
a clothes dryer. A dryer is a pump which draws make-up air from
the out-of-doors, through the heater, through the clothes and then
forces the air through the exhaust duct back to the out-of-doors.
Just as in a fluid water pump, there must be the proper fluid air
flow out of the exhaust duct.
In summary, there must be the proper size out-of-doors inlet air
opening (4-6 times the combined areas of the air outlet) and an
exhaust duct, with appropriate size and length, to allow air flow
through the dryer with no more than 0.3” w.. c. (.75 mbar) static
pressure in the exhaust duct.
In some instances, special fans are required to supply make-up air,
and/or boost exhaust fans are required for both regular and energy
savings models.
FOR BEST DRYING:
1 . Exhaust duct maximum length 14 feet (5 m) of straight
duct and maximum to two 90º bends.
2. Use 45º and 30º elbows wherever possible.
3 . Exhaust each dryer separately.
4 . Do not install wire mesh or other restrictions in the
exhaust duct.
5. Use clean-outs in the exhaust duct and clean periodically
when needed.
6 . Never exceed 0.3 inches w. c. (.75 mbar) static pressure in
the exhaust duct.
7 . Inside surface of the duct must be smooth.
8 . Recommend pop rivets for duct assembly.
FOR BEST DRYING:
1 . Provide opening to the out-of-doors in accordance with the
following:
For each dryer -
8 inches (204 mm) diameter exhaust requires 2 square feet
(.1858 m²) make-up air.
12 inches (305 mm) diameter exhaust requires 4 square feet
(.3716 m²) make-up air.
2 . Use barometric shutters in the inlet air opening to control
air when dryers are not running.
OTHER RECOMMENDATIONS
To assure compliance, consult local building code requirements.
T R O U B L E S H O O T I N G
Hot dryer surfaces, scorched clothes, slow drying, lint
accumulations, or air switch malfunction are indicators of exhaust
duct and/or make-up air problems.
