C. DRYER ENCLOSURE REQUIREMENTS
Even though a 12-inch (30.48 cm) clearance is acceptable, it is recommended that the rear of the dryer be
positioned approximately 2 feet (0.60 meters) from the nearest obstruction (i.e., wall) for ease of installation,
maintenance, and service. Bulkheads and partitions
should be
made from noncombustible materials. 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 dryer front. The bulkhead facing
must not be
closed
in
ALL
the way to the top of the dryer. A 2-inch (5.08 cm) clearance is required.
NOTE:
Bulkhead facing
should not be
installed until after dryer is in place. Ceiling area
must be
located a minimum of 12-inches (30.48 cm) above the top of the dryer.
IMPORTANT:
Even though a minimum of only 12-inches (30.48 cm) is required, 18-inches
(45.72 cm) or more is suggested, for steam dryers and especially in cases where
sprinkler heads are over the dryers.
NOTE:
When fire sprinkler systems are located above the dryers, a minimum of 18-inches (45.72 cm)
above the dryer console (module) is suggested. Dryers may be positioned sidewall to sidewall
however, 1 or 2-inches (2.54 cm or 5.08 cm) is suggested between dryers (or wall) for ease
of installation and maintenance. Allowances
must be
made for the opening and closing of the
control and lint doors.
