  • Page 17: Dryer Enclosure Requirements

    C. DRYER ENCLOSURE REQUIREMENTS Even though a 12-inch clearance is acceptable, it is recommended that the rear of the dryer be positioned approximately two (2) feet (24-inches) from the 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 four (4) inches and must not extend more than four (4) inches to the rear of the front.

  • Page 18: 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 out- doors.

  • 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 a. Outside Duct Work Protection 1) To protect the outside end of horizontal duct work from the weather, a 90° elbow bent down- ward 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.
  • Page 21 It is suggested that the duct work from each dryer (minimum of 14-inches for a gas dryer or a 72 Kw electric dryer and 16-inches for a steam dryer or an 80 Kw electric dryer) not exceed twenty (20) feet with no more than two (2) elbows (excluding dryer connection).
  • Page 22 14-inch (minimum for gas dryers or 72 Kw electric dryers) or 16-inch (minimum for steam dryers or 80 Kw electric dryers) duct is added. IMPORTANT: The ML-130 is not provided with a back draft damper. When exhausted into a multiple (common) exhaust line, a back draft damper must be installed at each dryer duct.
  • Page 23 IMPORTANT: Exhaust back pressure measured by a manometer in the exhaust duct should not exceed 0.3 inches of water column. 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.

  • Page 34 IMPORTANT: The dryer and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa). NOTE: The dryer must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure test of the gas supply system at test pressures equal to or less than 1/2 psig (3.5 kPa)

  • Page 35: Steam Information

    H. STEAM INFORMATION It is your responsibility to have ALL plumbing connections made by a qualified professional to assure that the gas plumbing installation is adequate and conforms with local and state regulations or codes. IMPORTANT: Failure to comply with the requirements stipulated in this manual can result in component failure which will VOID THE WARRANTY.
  • Page 36 b. The steam supply piping to the dryer must include a 12-inch rise along with a drip trap and check valve. This will prevent any condensate from entering the steam coil. c. Flexible hoses or couplings must be used. The dryer vibrates slightly when it runs and this will cause the steam coil connections to crack if they are hard piped to the supply and return mains.
  • Page 37 4. Steam Damper Air System Connections The M-130 is manufactured with a pneumatic (piston) damper system which requires an external supply of compressed air. The air connection is made to the steam damper solenoid valve which is located at the rear inner top area of the dryer just in front of the electric service relay box. (Refer to the bottom illustration on page 34).
  • Page 38 5. Steam Damper Air Piston (Flow Control) Operation Adjustment Although the steam damper operation was tested and adjusted prior to shipping at 80 PSI, steam damper operation must be checked before the dryer is put into operation. Refer to page 37 or instructions to check steam damper operation.

  • Page 39: Preparation For Operation/Start-Up

    I. PREPARATION FOR OPERATION/START-UP The following items should be checked before attempting to operate the dryer: 1.
