EXAMPLE: For a bank of 4 dryers, 2 unrestricted openings measuring 12-inches by
16-inches (30.5 cm by 40.64
cm) are acceptable.
Allowances must be made for remote or constricting passageways or where dryers are located at excessive altitudes
or predominantly low pressure areas.
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.
NOTE:
Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.
D. FRESH AIR SUPPLY REQUIREMENTS
This appliance may only be installed in a room that meets the appropriate ventilation requirements specified in the
national installation regulations.
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 may result, as well as premature motor failure from overheating. The dryer must be installed with provisions
for adequate combustion and make-up air supply.
Air supply (make-up air) must be given careful consideration to ensure proper performance of each dryer. As a
general rule, an unrestricted air entrance from the outdoors (atmosphere) measuring a minimum size of 8-inches by
12-inches (20.32 cm by 30.5 cm) is required for each dryer. (Based on 1 square inch per 1,000 Btu.)
To compensate for the use of registers or louvers used over the openings, this area must be increased by approximately
thirty-three percent (33%). Make-up air openings should not be located in an area directly near where exhaust vents
exit the building.
It is not necessary to have a separate make-up air opening for each dryer. Common make-up air openings are
acceptable. However, they must be set up in such a manner that the make-up air is distributed equally to all the
dryers.
