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, size and
length of which allows flow through the dryer with no more than 0.6 inches
water column 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 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 0.6 inches water column 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 diameter exhaust requires 2 square feet make-up
air.
12 inches diameter exhaust requires 4 square feet 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.
TROUBLESHOOTING
Hot dryer surfaces, scorched clothes, slow drying, lint accumulations, or air
switch malfunction are indicators of exhaust duct and/or make-up air
problems.
