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:
DRYER
MUST BE
EXHAUSTED TO THE OUTDOORS.
CAUTION: IMPROPERLY
SIZED
OR
INSTALLED
EXHAUST
DUCTWORK
CAN
CREATE
A
POTENTIAL
FIRE
HAZARD.
NOTE:
When a dryer is exhausted separately,
it is recommended
that a back draft damper be
installed.
NOTE:
When dryers are exhausted into a multiple (common) exhaust line, each dryer
must be
supplied with a back draft damper.
The exhaust 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. When
single dryer venting is used, the ductwork from the dryer to the outside exhaust outlet
must not
exceed
20
feet (6.09 meters). In the case of multiple (common) dryer venting, the distance from the last dryer to the
outside exhaust outlet
must not exceed
20 feet (6.09 meters). The shape of the ductwork is not critical so
long as the minimum cross section area is provided. It is suggested that the use of 90º turns in ducting be
avoided; use 30º and/or 45º angles instead. The radius of the elbows
should preferably be
1-1/2 times the
diameter of the duct. Excluding basket (tumbler)/dryer elbow connections or elbows used for outside
protection from the weather, no more than two (2) elbows
should be
used in the exhaust duct run. If more
than two (2) elbows are used, the cross section area of the ductwork
must be
increased in proportion to
number of elbows added.
