Page 15: Unpacking/Setting Up
10. The dryer must be installed with provisions for adequate combustion and make-up air supply. CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors. Every 6 months, inspect the exhaust ducting and remove any lint build up. IMPORTANT: Dryer must be installed in a location/environment, which the ambient temperature remains between 40°... - Page 16 c. Remove the four (4) self-taping screws on the burner box that secure it to the top of the dryer shown in the illustration below. d. Remove the two (2) self-taping screws on the back electrical box and pull through ALL associated wires from the motor to this electrical box (refer to the illustration below).

Page 17: Dryer Enclosure Requirements
C. DRYER ENCLOSURE REQUIREMENTS Bulkheads and partitions should be made of noncombustible materials and must be located a minimum of 12-inches (30.48 cm) (18-inches [45.72 cm] 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 4-inches (10.16 cm) and must not extend more than 4-inches (10.16 cm) 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 outdoors. If the make-up air is inadequate, drying time and drying efficiency will be adversely affected. -
Page 19: Exhaust Requirements
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, burner hi-limits, or basket (tumbler) hi-limit thermostats. - Page 20 NOTE: As per the National Fuel Gas Code, “Exhaust ducts for Type 2 clothes dryers shall be constructed of sheet metal or other noncombustible material. Such ducts shall be equivalent in strength and corrosion resistance to ducts made of galvanized sheet steel not less than 0.0195-inches (26 gauge [0.05 mm]) thick.”...
- Page 21 IMPORTANT: Exhaust back pressure measured by a manometer in the exhaust duct must be no less than 0 and must not exceed 0.3 inches (0.74 mb) of water column (W.C.). IMPORTANT: Minimum duct size for a dryer that is vented vertically is 12-inches (30.48 cm) for a round duct or an equivalent of 80 square inches (516.1 square centimeters).

- Page 25 SINGLE-PHASE (1Ø) ELECTRICAL CONNECTION LEADS Black Positive 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 26 1) Gas Models 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. For 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.
- Page 27 2) Electrically Heated 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. CAUTION: The dryer must be grounded.
- Page 28 c. 3-Phase (3ø) Wiring Connections (Hookup) For Reversing Models Only The electrical connections on ALL 3-phase (3ø) gas model dryers are made into the rear service box located at the upper left area of the dryer.
