It is recommended that the rear of the dryer be positioned approximately 3 feet (0.91 meters) from the nearest obstruction (i.e., wall) for ease of installation, maintenance, and service. Bulkheads and partitions should be made of noncombustible materials. 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 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.
