A. 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 unskid the dryer, locate and remove the four (4) bolts securing the base of the dryer to the wooden skid. Two (2) are at the rear base (remove the back panel for access), and two (2) are located in the bottom of the lint chamber. To remove the two (2) bolts located in the lint chamber area, remove the lint door.
With the skid removed, to make it easier to slide the dryer into its final position, slightly lower ALL four (4) leveling legs, so that the dryer will slide on the legs instead of the base frame.
Leveling Dryer
The dryer is equipped with four (4) leveling legs, one (1) at each corner of the base. Two (2) are located at the rear of the dryer base, and two (2) are located in the lint chamber (coop). To increase bearing life and improve efficiency, the dryer should be tilted slightly to the rear.
7
B. LOCATION REQUIREMENTS
Before installing the dryer, be sure the location conforms to local codes and ordinances. In the absence of such codes or ordinances the location must conform with the National Fuel Gas CodeANSI.Z223.1 LATEST EDITION, or in Canada, the installation must conform to applicable Canadian Standards: CAN/CGA-B149.1-M91 (Natural Gas) or CAN/CGA-B149.2-M91 (Liquid Propane [L.P.] Gas) or LATEST EDITION (for General Installation and Gas Plumbing).
1.The dryer must be installed on a sound level floor capable of supporting its weight. Carpeting must be removed from the floor area that the dryer is to rest on.
IMPORTANT: “The dryer must be installed on noncombustible floors only.”
2.The dryer must not be installed or stored in an area where it will be exposed to water and/or weather.
3.The dryer is for use in noncombustible locations.
4.Provisions for adequate air supply must be provided as noted in this manual (refer to Fresh Air Supply Requirements in Section D).
5.Clearance provisions must be made from combustible construction as noted in this manual (refer to Dryer Enclosure Requirements in Section C).
6.Provisions must be made for adequate clearances for servicing and for operation as noted in this manual (refer to Dryer Enclosure Requirements in Section C).
7.The dryer must be installed with a proper exhaust duct connection to the outside as noted in this manual (refer to Exhaust Requirements in Section E).
8.The dryer must be located in an area where correct exhaust venting can be achieved as noted in this manual (refer to Exhaust Requirements in Section E).
IMPORTANT: The dryer should be located where a minimum amount of exhaust duct will be necessary.
9. The dryer must be installed with adequate clearance for air openings into the combustion chamber.
CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors. Every 6 months, inspect the exhaust ducting and remove any lint buildup.
IMPORTANT: The dryer must be installed in a location/environment, which the ambient temperature remains between 40° F (4.44° C) and 130° F (54.44° C).
8
C. DRYER ENCLOSURE REQUIREMENTS
Bulkheads and partitions should be made of noncombustible material.
NOTE: Allowances must be made for opening the control door.
A30-inches (76.2 cm) for optimum opening of load door.
BThe maximum thickness of the bulkhead is 4-inches (10.16 cm). For electric 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.
CFor gas and electric dryers a minimum overhead clearance of 12-inches (30.48 cm) is required, providing no sprinkler is located above the dryer. For steam dryers or if a sprinkler is located above the dryer, 18-inches (45.72 cm) is required.
DDryer should be positioned 12-inches (30.48 cm) away from the nearest obstruction and 24-inches (60.96 cm) is recommended for ease of installation, maintenance, and service.
E2-inch (5.08 cm) minimum is required for opening the control door.
FFlooring should be level or below dryer cabinet for ease of removing panels during maintenance.
GDryers may be positioned sidewall to sidewall, however a 1/16” (1.5875 mm) minimum allowance must be made for the opening and closing of the control door, along with the removal of panels during maintenance.
9
D. FRESH AIR SUPPLY REQUIREMENTS
The air supply (make-up air) must be given careful consideration to ensure proper performance of each dryer. An unrestricted source of air is necessary for each dryer. As a general rule, an unrestricted air entrance from the outdoors (atmosphere) of a minimum of 1-1/2 square feet (0.14 square meters) is required for each dryer. If registers or louvers are installed over the openings, then the area must be increased. It is not necessary to have separate make-up air openings 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 the dryers. The dryer must be installed with provisions for adequate combustion and make-up air supply.
EXAMPLE: For a bank of eight (8) dryers, two (2) unrestricted openings measuring 3 feet by 2 feet (0.914 meters by 0.61 meters) are acceptable.
IMPORTANT: Make-up air openings should not be located in an area directly near where exhaust vents exit the building.
Allowances must be made for remote or constricting passageways or where dryers are located at excessive altitudes or predominantly low pressure areas.
IMPORTANT: Make-up air must be provided from a source free of contaminating fumes such as dry cleaning solvent fumes. Make-up air that is contaminated by dry cleaning solvent fumes will result in irreparable damage to the motors and other dryer components.
NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.
10
E. EXHAUST REQUIREMENTS
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, and shutdown of the burner by the airflow (sail) switch, burner hi-limits, or lint chamber hi-limit protector thermostat. The dryer must be installed with a proper exhaust duct connection to the outside.
When possible, it is suggested to provide a separate (single) exhaust duct for each dryer.
CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors.
CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCTWORK CAN CREATE A POTENTIAL FIRE HAZARD.
The exhaust ductwork 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. The shape of the ductwork is not critical as long as the minimum cross section area is provided. Single or independent dryer venting is recommended.
It is suggested that the use of 90° turns be avoided; use 30° or 45° angles instead.
The ductwork should be smooth inside with no projections from sheet metal screws or other obstructions, which will collect lint. When adding ducts, the ducts to be added should overlap the duct to which it is connected. ALL ductwork joints must be taped to prevent moisture and lint from escaping into the building. Additionally, inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning.
IMPORTANT: When connecting ductwork to the dryer exhaust duct, be sure that when screws are used they DO NOT restrict the operation (both opening and closing) of the damper.
NOTE: When the exhaust ductwork passes through a wall, ceiling, or roof made of combustible materials, the opening must be 2-inches (5.08 cm) larger than the duct (all the way around). The duct must be centered within this opening.
To protect the outside end of the horizontal ductwork from the weather, a 90° 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 180° turn to point the opening downward. In either case, allow at least twice the diameter of the duct between the duct opening and the nearest obstruction (i.e., roof or ground level).
IMPORTANT: DO NOT use screens, louvers, or caps on the outside opening of the exhaust ductwork.
IMPORTANT: Exhaust back pressure measured by a manometer at the dryer exhaust duct area must be no less than 0 and must not exceed 0.3 inches (0.74 mb) of water column (W.C.).
IMPORTANT: It is recommended that exhaust or booster fans not be used in the exhaust ductwork system.
