12 1. Leveling Dryer To level dryer, place 4-inch (10.16 cm) square metal shims (refer to the illustration on page 11 ) 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. a. To remove top c[...]

13 C. DR YER ENCLOSURE REQUIREMENTS Even though a 30-inch (76.2 cm) clearance is acceptable, it is recommended that the rear of the dryer be positioned approximately 36-inches (91.44 cm) from nearest obstruction (i.e. wall) for ease of installation, maintenance and service. Bulkheads and partitions should be made from noncombustible materials. The [...]

14 D. FRESH AIR SUPPL Y 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. Ignition pr[...]

15 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, bu[...]

16 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 ductwork travels as directly as possible to the outdoors with as few turns as possible. It is suggested that the use of 90° turns in the ducting be avoided ; use 30° or 45° angle[...]

17 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 one (1) elbow for horizontal runs and three (3) elbows for vertical runs. When the ductwork approa[...]

18 3. Multiple Dryer (common) Venting If it is not feasible to provide separate exhaust ducts for each dryer, ducts from individual dryers may be channeled into a "common main duct." The individual ducts should enter the bottom or side of the main duct at an angle not more than 45º in the direction of airflow and should be spaced at leas[...]

19 a. Outside Ductwork Protection 1) To protect the outside end of horizontal ductwork from the weather, a 90º 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 180º turn to point the opening downward. In either c[...]

20 Each dryer should be connected to an independently protected branch circuit. The dryer must be connected with copper wire only. DO NOT use aluminum wire, which could cause a fire hazard. The copper conductor wire or cable must be of proper ampacity and insulation in accordance with electric codes for making ALL service connections. NOTE : The us[...]

21 3. Grounding A ground (earth) connection must be provided and installed in accordance with state and local codes.

25 Consistent gas pressure is essential at ALL gas connections. It is recommended that a 1-inch (2.54 cm) pipe gas loop be installed in the supply line servicing 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 (29.9 mb) of water column (W.C.) pressur[...]

26 6. Be sure ALL side and base panels are on the dryer. 7. Check ALL service doors to insure that they are closed and secure. 8. Be sure the lint drawer is securely in place. IMPORTANT : LINT DRAWER MUST BE CLOSED TO ACTIVATE SAFETY SWITCH OTHERWISE THE DRYER WILL NOT START. 9. Rotate the basket (tumbler or drum) by hand to be sure it moves freely[...]

27 3) Once ignition is established, a gas pressure test should be taken at the gas valve pressure tap of each dryer to assure that the water column (W.C.) pressure is correct and consistent.
