C. DRYER ENCLOSURE REQUIREMENTS

Bulkheads and partitions

must be

made of noncombustible materials and

must be

located a minimum of

12-inches (30.48 cm), 18-inches (45.72 cm) or more is recommended for ease of installation, maintenance, and
service above the dryer outer top, except along the front of the dryer which may be partially closed in if desired.
The clearance between the bulkhead header and the dryer

must be

a minimum of 4-inches (10.16 cm) and must

not extend more than 4-inches (10.16 cm) to the rear of the front. The bulkhead facing

must not be

closed in

ALL

the way to the top of the dryer. A 1-inch (2.54 cm) clearance is required.

NOTE:

Allowances

must be

made for opening the control door.

Dryers may be positioned sidewall to sidewall. However, a 1/16” (1.5875 mm) minimum allowance

must be

made for the opening and closing of the control door and the lint door. It is suggested that the dryer be positioned
about 2 feet (0.61 meters) away from the nearest obstruction for ease of installation, maintenance, and service
(to be measured from the back guard). Refer to the

illustration above

for details.

NOTE:

Air considerations are important for proper and efficient operation.

IMPORTANT:

Even though a minimum of only 12-inches (30.48 cm) is required behind the dryer,
18-inches (45.72 cm) or more is suggested (especially when vertical venting is used).
The additional clearance is advantageous for ease of installation and service.

IMPORTANT:

When fire sprinkler systems are located above the dryers, a minimum of 18-inches
(45.72 cm) above the dryer console (module) is required. Dryers may be positioned
sidewall to sidewall, however, a 1/16” (1.5875 mm) minimum allowance is required
between dryers (or wall) for ease of installation and maintenance. Allowances

must

be

made for the opening and closing of the control door and the lint door.
