INSTALLATION REQUIREMENTS

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.

ANSI Z223.1 (LATEST EDITION) NATIONAL FUEL GAS CODE

ANSI/NFPA NO. 70 (LATEST EDITION) NATIONAL ELECTRIC CODES

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 coin machines.

Bulkheads and partitions around the dryer should be made of non-combustible 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 allow-

ances 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 over-

heating. On electric dryers, premature electric element failure may result. 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 irrepairable 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 air flow (sail) switch. (Refer to installation manual for more detail.)

CAUTION: Improperly sized, installed, or maintained (cleaned) exhaust duct work can create a

potential fire hazard.
