13 C . D R 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 two (2) feet (24-inches) - 0.61 meters (60.96 cm) - from the nearest obstruction (i.e., wall) for ease of installation, maintenance, and service. Bulkheads and partitions should be [...]

14 D . F R E S H AIR SUPPL Y REQUIREMENTS When the dryer is operating, it draws in room air, heats it, passes this air through the tumbler (basket), 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 aff[...]

15 E. EXHAUST REQUIREMENTS 1. General Exhaust Duct W ork Information Exhaust duct work should be designed and installed by a qualified professional. Improperly sized duct work 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) switc[...]

16 a . Outside Duct W ork Protection 1) T o protect the outside end of horizontal duct work from the weather , a 90° elbow bent downward should be installed where the exhaust exits the building. If the duct work travels vertically up through the roof, it should be protected from the weather by using a 180° turn to point the opening downward. In e[...]

17 It is suggested that the duct work from each dryer (minimum of 12-inches [30.48 cm] for a single dryer) not exceed 15 feet (4.57 meters) with no more than three (3) elbows (including dryer connection). If the duct work exceeds 15 feet (4.57 meters) or has numerous elbows, the cross-sectional area of the duct work must be increased in proportion [...]

18 NOTE: Where the exhaust duct passes through a wall, ceiling, or roof made of combustible materials, the opening must be 2-inches (5.08 cm) larger (all the way around) than the duct. The duct must be centered within this opening. a . Outside Duct W ork Protection 1) T o protect the outside end of horizontal duct work from the weather , a 90° elb[...]

19 The duct work 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 duct work joints must be taped to prevent moisture and lint from escaping into the building. Inspection doors should b[...]
