13 IMPORTANT: When fire sprinkler systems are located above the dryers, a minimum of 18-inches (45.72 cm) above the dryer console (module) is required. Dryers may be positioned sidewall to sidewall, however, a 1/16” (1.5875 mm) minimum allowance is required between dryers (or wall) for ease of installation and maintenance.
14 It is not necessary to have a separate make-up air opening for each dryer. Common make-up air openings are acceptable. However, they must be set up in such a manner that the make-up air is distributed equally to ALL the dryers. EXAMPLE: For a bank of four (4) dryers, two (2) openings measuring 2 feet by 2-1/2 feet (0.
15 ALL ductwork should be smooth inside with no projections from sheet metal screws or other obstructions, which will collect lint. When adding ducts, the duct to be added should overlap the duct to which it is to be connected. ALL ductwork joints must be taped to prevent moisture and lint from escaping into the building.
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 ductwork travels as directly as possible to the outdoors with as few turns as possible.
17 IMPORTANT: For extended ductwork runs, the cross section area of the ductwork can only be increased to an extent. Maximum proportional ductwork runs cannot exceed 15 feet (4.57 meters) more than the original limitations of 15 feet (4.57 meters) with two (2) elbows.
18 IMPORTANT: For extended ductwork runs, the cross section area of the ductwork can only be increased to an extent. Maximum proportional ductwork runs, cannot exceed 15 feet (4.57 meters) more than the original limitations of 15 feet (4.57 meters) with two (2) elbows.
