    INSTALLATION PROCEDURES Installation should be performed by competent technicians in accordance with local and state codes. In the absence of these codes, the installation must conform to applicable American National Standards: National Fuel Gas Code ANSI.Z223.1-LATEST EDITION or National Electric Code ANSI/NFPA NO. 70-LATEST EDITION, or in CANADA, the installation must conform to applicable CANADIAN STANDARDS: CAN/ CGA-B149.1-M91 (Natural Gas).

  • Page 14: Unpacking/Setting Up

    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 while still attached to the skid or with the skid removed. To un-skid the dryer, locate and remove the four (4) bolts securing the base of the dryer to the wooden skid.
  • Page 15 1. Leveling Dryer To level dryer, place 4-inch square metal shims (refer to the illustration on page 10) or other suitable material under the base pads. It is suggested that the dryer be tilted slightly to the rear. If more headroom is needed when moving dryer into position, the top console (module) may be removed.

  • Page 16: Dryer Enclosure Requirements

    C. DRYER ENCLOSURE REQUIREMENTS Even though a 30-inch clearance is acceptable, it is recommended that the rear of the dryer be positioned approximately two (3) feet (36-inches) from nearest obstruction (i.e. wall) for ease of installation, maintenance and service. Bulkheads and partitions should be made from noncombustible materials. The clearance between the bulkhead header and the dryer must be a minimum of 4 inches and must not extend more than 4 inches to the rear of the dryer front.

  • Page 17: Fresh Air Supply

    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.

  • Page 18: Exhaust Requirements

    E. EXHAUST REQUIREMENTS 1. General Exhaust Duct Work 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 shutdown of the burner by the airflow (sail) switches, burner hi-limits, or basket (tumbler) hi-heat thermostats.
  • Page 19 IMPORTANT: DO NOT use screens or caps on the outside of opening of exhaust duct work. 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.
  • Page 20 IMPORTANT: For extended duct work runs, the cross section area of the duct work 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 one (1) elbow for horizontal runs and three (3) elbows for vertical runs.
  • Page 21 IMPORTANT: For extended duct work runs, the cross section area of the duct work can only be increased to an extent. Maximum proportional duct work runs cannot exceed fifteen (15) feet with two (2) elbows. When the duct work approaches the maximum limits as noted in this manual, a professional HVAC firm should be consulted for proper venting.

  • Page 28: Preparation For Operation/Start-Up

    Consistent gas pressure is essential at ALL gas connections. It is recommended that a 1-inch pipe gas loop be installed in the supply line serving a bank of dryers. An in-line pressure regulator must be installed in the gas supply line (header) if the (natural) gas pressure exceeds 12.0 inches of water column (W.C.) pressure. NOTE: A water column (W.C.) test pressure of 3.5 inches for natural gas and 10.5 inches for L.P.
