SECTION III
INSTALLATION REQUIREMENTS
Installation should be performed by competent technicians in accordance with local and state codes. In
the absence of these codes, the installation must conform to applicable American National Standards:
ANSI Z223.1-LATEST EDITION (National Fuel Gas Code) or ANSI/NFPA NO. 70-LATEST EDITION
(National Electrical Code) or in Canada, the installation must conform to applicable Canadian Standards:
CAN/CGA-B149.1-M91 (Natural Gas) or CAN/CGA-B149.2-M91 (Liquid Propane [L.P.] Gas) or LATEST
EDITION (for General Installation and Gas Plumbing) or Canadian Electrical Codes Parts 1 & 2 CSA
C22.1-1990 or LATEST EDITION (for Electrical Connections).
A. ENCLOSURE, AIR SUPPLY, AND EXHAUST REQUIREMENTS
NOTE: The following information is very brief and general. For a detailed description refer
to the installation booklet for non-coin dryers.
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 installation manual for recommended distances
and minimum allowances required.)
When the dryer is operating, it draws in room air, heats it, passes the air through the tumbler, and
exhausts it out 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. On electric dryers, premature electric element failure may result. Air
supply must be given careful consideration to ensure proper performance of each dryer.
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.
Exhaust ductwork should be designed and installed by a qualified professional. Improperly sized ductwork
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.
CAUTION: IMPROPERLY SIZED OR INSTALLED OR MAINTAINED (CLEANED)
EXHAUST DUCTWORK CAN CREATE A POTENTIAL FIRE HAZARD.
