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 two (2) feet (24-inches) - 0.61 meters (60.96 cm) - 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 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 the 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 side wall to side
wall, however, 1 or 2-inches (2.54 or 5.08 cm) is suggested for ease of installation and
maintenance. Allowances must be made for the opening and closings of the control door and
the lint door.
