To compensate for the use of registers or louvers used over
the openings, this make-up air
must be increased by
approximately thirty-three percent (33%). Make-up air
openings
should not be located in an area directly near where
exhaust vents exit the building.
It is not necessary to have a separate make-up air opening
for each dryer. Common make-up air openings are acceptable.
However, they
must be set up in such a manner that the
make-up air is distributed equally to ALL the dryers.
EXAMPLE : For a bank of four (4) dryers, two (2) unrestricted
openings measuring 26-inches by 26.9-inches (66.1 cm by
68.4 cm) each are acceptable.
Allowances must be made for remote or constricting
passageways or where dryers are located at excessive
altitudes or predominantly low pressure areas.
IMPORTANT: Make-up air must be provided from a source free of dry cleaning solvent fumes. Make-up
air that is contaminated by dry cleaning solvent fumes will result in irreparable damage to the
motors and other dryer components.
NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.
E. EXHAUST REQUIREMENTS
1. General Exhaust Ductwork Information
Exhaust ductwork should be designed and installed by a qualified professional. Improperly sized ductwork will
create excessive back pressure which results in slow drying, increased use of energy, overheating of the dryer, and
shutdown of the burner by the airflow (sail) switches, burner hi-limits, or basket (tumbler) hi-heat thermostats. The
dryer
must be installed with a proper exhaust duct connection to the outside.
CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors.
CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCTWORK CAN CREATE A
POTENTIAL FIRE HAZARD .
NOTE: When dryers are exhausted into a multiple (common) exhaust line, each dryer must be supplied with a
back draft damper.
The ductwork should be laid out in such a way that the ductwork travels as directly as possible to the outdoors with
as few turns as possible. Single or independent dryer venting is recommended.
