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: National Fuel
Gas Code ANSI.Z223.1-LATEST EDITION or National Electrical Code ANSI/NFPA No. 70-LATEST EDITION,
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
ML-130 Installation Manual (ADC Part No. 113002).
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 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 tumbler (basket), 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 shut down 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 details.)
CAUTION: IMPROPERLY SIZED or INSTALLED EXHAUST DUCT WORK 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 with local and state regulations or codes. In the
absence of such codes, ALL electrical connections, material, 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 (for Electrical Connections).
