    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 and/or National Electric Code ANSI/NFPA NO. 70-LATEST EDITION.

  • Page 15: Unpacking/Setting Up

    B. UNPACKING/SETTING UP Remove protective shipping material (i.e., plastic wrap, and/or 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 16: Dryer Enclosure Requirements

    C. DRYER ENCLOSURE REQUIREMENTS Bulkheads and partitions should be made of noncombustible materials and must be located a minimum of twelve (12) inches (18-inches) or more is recommended for ease of installation, maintenance, and service) above the dryer outer top, except along the front of the dryer which may be partially closed in if desired. The clearance between the bulkhead header and the dryer must be a minimum of four (4) inches and must not extend more than four (4) inches to the rear of the front.

  • Page 17: Fresh Air Supply

    IMPORTANT: Even though a minimum of only 12-inches is required, 18-inches or more is suggested. The additional clearance is advantageous for ease of installation and service. IMPORTANT: When fire sprinkler systems are located above the dryers, a minimum of 18-inches above the dryer console (module) is required.
  • Page 18 To compensate for the use of registers or louvers used over the openings, this make-up air must be increased by approximately thirty-three percent (33%). Make-up air openings should not be located in an area directly near where exhaust vents exit the building. It is not necessary to have a separate make-up air opening for each dryer.

  • Page 19: 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 20 IMPORTANT: Minimum duct work diameter for horizontal venting is 10-inches and for vertical venting the minimum is 12-inches. NOTE: Where the exhaust duct work passes through a wall, ceiling, or roof made of combustible materials, the opening must be 2-inches larger (all the way around) than the duct. The duct must be centered within this opening.
  • Page 21 IMPORTANT: Minimum duct size for a dryer that is vented vertically is 12-inches for a round duct or an equivalent of 120 square inches. THE DUCT SIZE MUST NOT BE REDUCED ANYWHERE DOWN STREAM OF THE DRYER. IMPORTANT: For extended duct work runs, the cross section area of the duct work can only be extent.

Fuse ratings are dual-element, time-delay, current limiting, class RK1 or RK5 ONLY. B. Circuit breakers are thermal magnetic (industrial) type ONLY. For others, calculate/verify correct breaker size according to appliance amp draw rating and type of breaker used.
  • Page 25 3. Grounding A ground (earth) connection must be provided and installed in accordance with state and local codes. In the absence of these codes, grounding must conform to applicable requirements of the National Electric Code ANSI/NFPA NO. 70-LATEST EDITION. The ground connection may be to a proven earth ground at the location service panel.
  • Page 26 INGLE HASE LACK OSITIVE If local codes permit, power to the dryer can be made by the use of a flexible U.L. listed power cord/ pigtail (wire size must conform to rating of dryer), or the dryer can be hard wired directly to the service breaker panel.
  • Page 27 1) Gas Models ONLY The only electrical input connections to the dryer are the 3-phase (3ø) power leads (L1, L2, L3, and sometimes neutral) and ground. Single-phase (1ø) power for the control circuit is done internally to the dryer. No single-phase (1ø) input connection is required on a 3-phase (3ø) dryer. Gas dryers manufactured for operation at 3-phase (3ø), the electrical connections are made at the power distribution block located in the service box at the rear, upper left corner of the dryer.

Gas Connections: Inlet connection ---------- 3/4-inch N.P.T. Inlet supply size ---------- 3/4-inch N.P.T. (minimum) Btu/hr input (per dryer) - 204,000 1) Natural Gas Regulation is controlled by the dryer's gas valve's internal regulator.
  • Page 30 3. Piping/Connections ALL components/materials must conform to National Gas Code specifications. It is important that gas pressure regulators meet applicable pressure requirements and that gas meters be rated for the total amount of ALL the appliance BTU's being supplied. The dryer is provided with a 3/4" N.P.T. inlet pipe connection located at the right side of the base of the dryer.
  • Page 31 Consistent gas pressure is essential at ALL gas connections. It is recommended that a 2-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 pressure. NOTE: A water column test pressure of 3.5 inches for natural gas and 10.5 inches for L.P.
