IMPORTANT: Dryer must be installed in a location/environment, which the ambient temperature remains between 40º F (4.44º C) and 130º F (54.44º C). B. UNPACKING/SETTING UP Remove protective shipping material (i.e., plastic wrap and optional shipping box) from dryer. IMPORTANT: Dryer must be transported and handled in an upright position at ALL times. The dryer can be moved to its final location with or without the skid attached. To unskid the dryer, locate and remove the four (4) bolts securing

C. DRYER ENCLOSURE REQUIREMENTS Bulkheads and partitions should be made of noncombustible material. NOTE: Allowances must be made for opening the control door. A 40-inches (101.6 cm) for optimum opening of load door. B The maximum thickness of the bulkhead is 4-inches (10.16 cm). For electric dryers the maximum thickness of the bulkhead is 1-inch (2.54 cm) within 3-inches (7.62 cm) from the top of the control door. C For gas and electric dryers a minimum overhead clearance of 12-inches (30.48

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. Ignition problems and sail switch “fluttering” problems may result, as well as premature motor failure from overheating. Air supply (make-up air) mu

E. EXHAUST REQUIREMENTS 1. General Exhaust Ductwork Information Exhaust ductwork should be designed and installed by a qualified professional. Improperly sized ductwork will create excessive back pressure which results in slow drying, increased use of energy, overheating of the dryer, and shut down of the burner by the airflow (sail) switches, burner hi-limits, or basket (tumbler) hi-heat thermostats. The dryer must be installed with a proper exhaust duct connection to the outside. CAUTION: T

Outside Ductwork Protection To protect the outside end of the horizontal ductwork from the weather, a 90º elbow bent downward should be installed where the exhaust exits the building. If the ductwork travels vertically up through the roof, it should be protected from the weather by using a 180º turn to point the opening downward. In either case, allow at least twice the diameter of the duct opening and the nearest obstruction. IMPORTANT: DO NOT use screens, louvers, or caps on the outside open

IMPORTANT: For extended ductwork runs, the cross section area of the ductwork can only be increased to an extent. When the ductwork approaches the maximum limits noted in this manual, a professional heating, ventilating, and air-conditioning (HV AC) firm should be consulted for proper venting information. 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 duc

IMPORTANT: No more than four (4) dryers should be connected to one (1) main common duct. The main duct may be any shape so long as the minimum cross-sectional area is provided. The illustration on page 16 shows the minimum cross section area for multiple dryer round or square venting. These figures must be increased 10 square inches (64.52 squares centimeters) when rectangular main ducting is used, and the ratio of duct width to depth should not be greater than 3-1/2 to 1. These figures must
