  • Page 16: Fresh Air Supply Requirements

    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.

  • Page 17: Exhaust Requirements

    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 shutdown of the burner by the airflow (sail) switches, burner hi-limits, or basket (tumbler) hi-heat thermostats.
  • Page 18 Outside Ductwork Protection To protect the outside end of the horizontal ductwork from the weather, a 90° 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 180° turn to point the opening downward. In either case, allow at least twice the diameter of the duct between the duct opening and the nearest obstruction.
  • Page 19 Horizontal Venting: When single dryer horizontal venting is used, the length of ductwork from the dryer to the outside exhaust outlet must not exceed 45 feet (13.71 meters). The minimum diameter of this ductwork must be at least 20-inches (50.8 cm). The shape of the ductwork is not critical as long as the minimum cross-sectional area is provided.
  • Page 20 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 as noted in this manual, a professional heating, ventilating, and air conditioning (HVAC) firm should be consulted for proper venting information.
  • Page 21 The main duct may be any shape or cross-sectional area, as long as the minimum cross section area is provided. The illustration below shows the minimum cross section area for multiple dryer round or square venting. These figures must be increased 10 square inches (64.52 square 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.
  • Page 22 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 20 feet (6.1 meters) more than the original limitations of 20 feet (6.1 meters) with two (2) elbows.
