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 (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 Manual supplied with the 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 drawer. Also, allowances should be made in the rear for
ease of maintenance. (Refer to the appropriate Installation Manual for recommended distances and minimum
When the dryer is operating, it draws in room air, heats it, passes this air through the 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 the
motors and other dryer components.
Exhaust ductwork should be designed and installed by a competent technician. 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, burner hi-limit or lint chamber hi-heat protector thermostat. (Refer to the appropriate Installation
Manual for more details.)
CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCTWORK CAN CREATE A
POTENTIAL FIRE HAZARD.
B. ELECTRICAL AND GAS REQUIREMENTS
It is your responsibility to have all electrical connections made by a properly licensed and competent electrician to
assure that the electrical installation is adequate and conforms to local and state regulations or codes. In the absence
of such codes, all electrical connections, materials, and workmanship must conform to the applicable requirements
of the National Electrical Code ANSI/NFPA NO. 70-LATEST EDITION or in Canada, the Canadian Electrical Codes
Parts 1 & 2 CSA C22.1-1990 or LATEST EDITION.
IMPORTANT: Failure to comply with these codes or ordinances and/or the requirements stipulated
in this manual can result in personal injury or component failure.
