Installation should be performed by competent technicians in accordance with local and state codes. In the
absence of these codes, installation must conform to applicable AMERICAN NATIONAL STANDARDS:
National Fuel Gas Code ANSI Z223.1-LATEST EDITION
and/or
National Electric Code ANSI/NFPA No. 70-LATEST EDITION
A. Enclosure, Air Supply, and Exhaust Requirements
NOTE: The following information is very brief and general. For detailed description, refer
to the Installation Manual supplied with dryer.
Bulkheads and partitions around the dryer should be made of noncombustible materials. Allowances should be
made for the opening and closing of the control door and lint door. Also, allowances should be made in the rear
for ease of maintenance. (Refer to appropriate Installation Manual for recommended distances and minimum
allowances required.)
When the dryer is operating, it draws in room air, heats it, passes this air through the basket (tumbler), and
exhausts it out of the building. Therefore, the room air must be continually replenished from the outdoors. If the
make-up air is inadequate, drying time and drying efficiency will be adversely affected. Ignition problems and
sail switch "fluttering" problems on gas dryers may result, and you also could have premature motor failure
from overheating. The air supply must be given careful consideration to insure proper performance of each
dryer.
IMPORTANT: Make-up air must be provided from a source free of dry cleaning fumes.
Make-up air that is contaminated by dry cleaning fumes will result in
irreparable damage to motors and other dryer components.
Exhaust duct work should be designed and installed by a competent technician. Improperly sized duct work
will create excessive back pressure which will result in slow drying, increased use of energy, and shutdown of
the burner by the airflow (sail) switch, burner hi-limit or lint chamber hi-heat protector thermostat. (Refer to
appropriate Installation Manual for more detail.)
CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCT WORK CAN
CREATE A POTENTIAL FIRE HAZARD.
