Special provisions for mobile homes: Exhaust vent must be securely fastened to a noncombustible portion of mobile home and must not terminate beneath the mobile home. Terminate exhaust vent outside. Determine vent path: ■■Select route that will provide straightest and most direct path outdoors. ■■Plan installation to use fewest number of elbows and turns. ■■When using elbows or making turns, allow as much room as possible. ■■Bend vent gradually to avoid kinking. ■■Use as few 90° turns as possible. Determine vent length and elbows needed for best drying performance: ■■Use the "Vent System Charts" on the next page to determine type of vent material and hood combinations acceptable to use. NOTE: Do not use vent runs longer than those specified in "Vent System Charts." Exhaust systems longer than those specified will: ■■Shorten life of dryer. ■■Reduce performance, resulting in longer drying times and increased energy usage. The "Vent System Charts" provide venting requirements that will help achieve best drying performance. Standard Vent System Chart Number of 90° elbows Type of vent Angled hoods 0 Rigid metal 64 ft. (20 m) 1 Rigid metal 54 ft. (16.5 m) 2 Rigid metal 44 ft. (13.4 m) 3 Rigid metal 35 ft. (10.7 m) 4 Rigid metal 27 ft. (8.2 m) Long Vent System Chart Number of 90° elbows Type of vent Angled hoods 0 Rigid metal 160 ft. (48.8 m) 1 Rigid metal 150 ft. (45.7 m) 2 Rigid metal 140 ft. (42.7 m) 3 Rigid metal 130 ft. (39.6 m) 4 Rigid metal 120 ft. (36.6 m) To determine if your model has a long vent system, refer to the type code located on the serial number plate in the inner door well. Example: An electric model would be DALV - ELE - XXXXXXX-XXX. A gas model would be DALV - GAS - XXXXXXX-XXX. NOTE: For long vent systems, use of box/louvered hoods will improve venting regardless of length. Install Vent System 1. Install exhaust hood 12" min. (305 mm) 12" min. (305 mm) Install exhaust hood and use caulking compound to seal exterior wall opening around exhaust hood. 2. Connect vent to exhaust hood Vent must fit over the exhaust hood. Secure vent to exhaust hood with 4" (102 mm) clamp. Run vent to dryer location using straightest path possible. Avoid 90° turns. Use clamps to seal all joints. Do not use duct tape, screws, or other fastening devices that extend into interior of vent to secure vent, because they can catch lint. 12
