Page 15: Installation Procedures
SECTION III INSTALLATION PROCEDURES Installation should be performed by competent professional in accordance with local, state, and country codes. A. LOCATION REQUIREMENTS Before installing the dryer, be sure the location conforms to local, state, and country codes. In the absence of such codes or ordinances the installation must conform with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1/NFPA 54, or the Natural Gas and Propane Installation Code, CSA B149.1 or LATEST EDITION (for General Installation and Gas Plumbing). -
Page 16: 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 unskid the dryer, locate and remove the four (4) lag bolts securing the base of the dryer to the wooden skid. - Page 17 To Remove Top Console (module): a. Disconnect the ground wire (A in the illustration below) located at the rear upper left corner of the dryer. b. Remove the six (6) sets of nuts and washers (B in the illustration below) holding the console (module) to the base.

Page 18: Dryer Enclosure Requirements
C. DRYER ENCLOSURE REQUIREMENTS Bulkheads and partitions should be made of noncombustible material. NOTE: Allowances must be made for opening the control door. 38-inches (76.2 cm) for optimum opening of load door. The maximum thickness of the bulkhead for gas dryers is 4-inches (10.16 cm). For electric and steam dryers the maximum thickness of the bulkhead is 1-inch (2.54 cm) within 3-inches (7.62 cm) from the top of the control door. -
Page 19: Exhaust Requirements
It is not necessary to have a separate make-up air opening for each dryer. Common make-up air openings are acceptable. However, they must be set up in such a manner that the make-up air is distributed equally to ALL the dryers. EXAMPLE: For a bank of six (6) dryers, two (2) unrestricted openings measuring 3 feet by 3 feet (0.91 meters by 0.91 meters) are acceptable. - Page 20 When single dryer venting is used, the ductwork from the dryer to the outside exhaust outlet should not exceed 20 feet (6.09 meters). In the case of multiple (common) dryer venting, the distance from the last dryer to the outside exhaust outlet should not exceed 20 feet (6.09 meters). The shape of the ductwork is not critical as long as the minimum cross-sectional area is provided.
- Page 21 IMPORTANT: The minimum duct size for a gas unit is 16-inches (40.64 cm), (12-inches [30.4 cm] for MLG-122DR), for a round duct and 14-1/4” x 14-1/4” (36.2 cm x 36.2 cm), (10-3/4 x 10-3/4 [27.3 cm x 27.3 cm] for MLG-122DR), for a square duct. THE DUCT SIZE MUST NOT BE REDUCED ANYWHERE DOWNSTREAM OF THE DRYER.
- Page 22 (123.82 cm) apart. The main duct should be tapered, with the diameter increasing before each individual 16-inch (40.64 cm), (12-inches [30.4 cm] for MLG-122DR) duct. IMPORTANT: When exhausted into a multiple (common) exhaust line, a back draft damper must be installed at each dryer duct.
- Page 23 ML-122 Multiple Dryer Venting 16-Inch (40.64 cm) Diameter Minimum Exhaust Connections at Common Duct 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 (6.09 meters) more than the original limitations of 20 feet (6.09 meters) with two (2) elbows.
- Page 24 2-inches (5.08 cm) larger than the duct (all the way around). The duct must be centered within this duct. MLG-122DR Multiple Dryer Venting 12-Inch (30.48 cm) Diameter Minimum Exhaust Connections at Common Duct American Dryer Corp.

6. Steam Damper Air Piston (Flow Control) Operation Adjustment Although the steam damper operation was tested and adjusted prior to shipping at 80 psi (5.51 bar), steam damper operation must be checked before the dryer is put into operation. Refer to page 34 for instructions to check steam damper operation. - Page 35 INSTALLATION 1. Requirements The fire suppression system must be supplied with a minimum water pipe size of 1/2” and be provided with 40 psi +/- 20 psi (2.75 bar +/- 1.37 bar) of pressure. For use of optional manual bypass, a second source with the same piping and pressure requirements is required.
- Page 36 OPTIONAL MANUAL BYPASS Provisions are made in the dryer’s fire suppression system for the installation of an optional manual bypass. Depending on the model dryer, the connections for the manual bypass are made at the “T” or “three way” fitting located in the outlet supply side of the water solenoid valve.
-
Page 37: Preparation For Operation/Start-Up
WARNING: Electrical power must be provided to the dryer at ALL times. If the main electrical power supply to the dryer is disconnected, the fire suppression system is INOPERATIVE!! WARNING: ELECTRICAL SHOCK HAZARD – Electrical shock hazard can result in serious injury. -
Page 38: Preoperational Test
K. PREOPERATIONAL TEST ALL dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test should be performed before the dryer is publicly used. It is possible that adjustments have changed in transit or due to marginal location (installation) conditions. Installer must instruct the user on how to correctly operate the dryer before leaving. -
Page 39: Preoperational Instructions
6. Make a complete operational check of ALL safety-related circuits (i.e., lint drawer switch, and sail switch on gas models). NOTE: To check for proper sail switch operation, open the main door and while holding main door switch plunger in, start the dryer. The dryer should start but the heat circuit should not be activated (on). - Page 40 NOTE: Press and hold the “UP ARROW” to view the tumbler temperature at any time. NOTE: The dryer can be stopped at any time by pressing the “STOP/CLEAR” key, at this time the dryer will go into a cycle pause. If the “STOP/CLEAR” key is pressed again at this point, the cycle that was in progress will be cancelled and returned to the “READY”...
