Dimensions and Clearances
Spacing for Recessed Area or Closet Installation
Recommended clearances for this dryer are 1 inch (2.5 cm) on the sides and rear. Additional clearances are advised for easier installation, servicing, and noise reduction. For closet installations with doors, minimum ventilation openings are required at the top and bottom of the door. Louvered doors with equivalent ventilation openings are acceptable.
Closet Ventilation Requirements:
Closets require upper and lower vents to prevent heat and moisture buildup. An upper vent opening of at least 48 sq. in. (310 cm²) is needed, no lower than 6 feet from the floor. A lower vent opening of at least 24 sq. in. (155 cm²) is needed, no more than one foot above the floor. Vent grills can be installed in the door, or the door can be cut down to create openings.
Diagram Description: The document shows diagrams illustrating required spacing. One diagram shows a dryer with 1" (25 mm) spacing on sides and rear, 14" (356 mm) clearance above, and 18" (457 mm) clearance in front. Another diagram illustrates closet door vent requirements with a 48 sq. in. (310 cm²) upper opening and a 24 sq. in. (155 cm²) lower opening, with 3" (76 mm) spacing from the dryer to the wall.
Installation Spacing for Cabinet
For cabinet installations with a door, minimum ventilation openings in the top of the cabinet are required. The diagrams show specific clearances for cabinet installation, including 7" (178 mm) spacing on the sides and rear, and 9" (229 mm) clearance above.
Diagram Description: Diagrams show a dryer within a cabinet. One shows clearances for a single dryer in a cabinet: 7" (178 mm) on sides and rear, 9" (229 mm) above. Another shows a stacked washer and dryer in a closet, detailing vent openings (48 sq. in. top, 24 sq. in. bottom) and 3" (76 mm) spacing from the dryer to the wall. For side or bottom venting, 2-inch (51 mm) spacing is allowed. Stacked unit height is 77 1/2" (1968 mm).
Venting the Dryer
Ensure existing ductwork is suitable and clean before installation. Venting must comply with local building codes. Gas dryers must exhaust outdoors. Use only 4-inch (10.2 cm) diameter rigid, semi-rigid, or flexible metal ductwork. The exhaust duct should be as short as possible and free of obstructions. Rigid, semi-rigid, or flexible metal ducting is recommended between the dryer and the wall. All non-rigid metal transition duct must be UL-listed. Ductwork is not provided. The vent hood should have hinged dampers. The total length of flexible metal duct must not exceed 8 ft. (2.4 m). Deduct 6 ft. (1.8 m) for each additional 90° elbow, and do not use more than four 90° elbows.
| Wall Cap Type | Number of 90° Elbows | Maximum length of 4-inch diameter rigid metal duct |
|---|---|---|
| Recommended 4" (102 mm) | 0 | 65 ft. (19.8 m) |
| 1 | 55 ft. (16.8 m) | |
| 2 | 47 ft. (14.3 m) | |
| 3 | 36 ft. (11.0 m) | |
| 4 | 28 ft. (8.5 m) | |
| Use only for short run installations 2 1/2" (635 mm) | 0 | 55 ft. (16.8 m) |
| 1 | 47 ft. (14.3 m) | |
| 2 | 41 ft. (12.5 m) | |
| 3 | 30 ft. (9.1 m) | |
| 4 | 22 ft. (6.7 m) |
Routing and Connecting Ductwork
To maximize drying performance and reduce lint buildup/condensation, use 4-inch (10.2 cm) diameter rigid, semi-rigid, or flexible metal ductwork. Keep the exhaust duct run as short as possible with minimal elbow joints. The male end of each duct section must point away from the dryer. Use duct tape on all joints. Insulate ductwork in unheated areas. Incorrect or inadequate exhaust systems are not covered by the dryer warranty.

Electrical and Gas Connections
Connecting Gas Dryers
Gas Supply Requirements: The dryer is configured for natural gas (NG) and can be converted for propane (LP) gas. Gas pressure must not exceed 8-inch (20.4 cm) water column for NG or 13-inch (33.1 cm) water column for LP. A qualified technician must connect the dryer to the gas service.
Electrical Requirements for Gas Models Only: Plug into a 120-VAC, 60-Hz. grounded outlet protected by a 15-ampere fuse or circuit breaker. The dryer has a three-prong grounding plug for shock hazard protection; do not cut or remove the grounding prong.
Connecting Electric Dryers
Electrical Requirements for Electric Models Only: Connect to a grounded metal, permanent wiring system, or run an equipment-grounding conductor with circuit conductors to the dryer's grounding terminal. The dryer requires a separate 240 VAC, 60-Hertz, single-phase circuit, fused at 30 amperes (fused on both sides of the line). Do not connect to 110-, 115-, or 120-VOLT circuits. For branch circuits 15 ft. (4.5 m) or less, use UL-listed No.-10 AWG copper wire. For circuits over 15 ft. (4.5 m), use UL-listed No.-8 AWG copper wire. Allow sufficient slack for moving the dryer. The power cord (pigtail) is not supplied and must conform to local codes.
Diagram Description: The document shows connection locations. For gas models, it indicates power cord and gas connection points. For electric models, it shows the terminal block access panel and exhaust duct outlet.
Wiring Options
Four-Wire Power Cord: A 4-wire connection is required for mobile/manufactured homes and new construction after January 1, 1996. Requires a UL-listed strain relief. Use a 30-amp, 240-volt, 4-wire, UL-listed power cord with #10 AWG minimum copper conductor and appropriate terminals.
Four-Wire Direct Wire: A 4-wire connection is required for mobile/manufactured homes and new construction after January 1, 1996. Requires a UL-listed strain relief. Use UL-listed 4-wire #10 AWG minimum copper conductor cable, allowing at least 5 ft. (1.5 m) of wire for removal and reinstallation.
