12 C. DRYER ENCLOSURE REQUIREMENTS Even though a 12-inch clearance is acceptable, it is recommended that the rear of the dryer be positioned approximately two (2) feet (24-inches) from the nearest obstruction (i.e., wall) for ease of installation, mainte- nance, and service. Bulkheads and partitions should be made from noncombustible materials. The[...]

13 D. FRESH AIR SUPPLY 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. Ignition pro[...]

14 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 motors and other dryer components. NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY . E. EXHAUST REQUIREMENTS 1. GENERAL EXHA[...]

15 ALL duct work 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 con- nected. ALL duct work joints must be taped to prevent moisture and lint from escaping into the building. Additionally, inspection doo[...]

16 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 duct work 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[...]

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

18 The main duct may be any shape or cross sectional area, so long as the minimum cross section area is provided. The illustrations on page 19 and page 20 show the minimum cross section area for multiple dryer round or square venting. These figures must be increased 10 square inches when rectangular main ducting is used, and the ratio of duct width[...]
