14 C. DR YER 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 material[...]

15 D. FRESH AIR SUPPLY REQUIREMENTS When the dryer is operating, it draws in room air, heats it, passes this air through the basket (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.[...]

16 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 . E. EXHAUST REQUIREMENTS 1. General [...]

17 ALL ductwork should be smooth inside with no projections from sheet metal screws or other obstructions, which will collect lint. When adding ducts, the ducts to be added should overlap the duct to which it is connected. ALL ductwork joints must be taped to prevent moisture and lint from escaping into the building. Additionally, inspection doors [...]

18 2. Single Dryer Venting Where possible, it is suggested to provide a separate exhaust duct for each dryer. The exhaust duct should be laid out in such a way that the ductwork travels as directly as possible to the outdoors with as few turns as possible. It is suggested that the use of 90° turns in ducting be avoided ; use 30° and/or 45° angle[...]

19 IMPORTANT: For extended ductwork runs, the cross section area of the duct can only be increased to an extent. Maximum proportional ductwork runs cannot exceed 20 feet (6.09 meters) more than the original limitations of 20 feet (6.09 meters) with two (2) elbows. When the ductwork approaches the maximum limits as noted in this manual, a profession[...]
