(27.4 m) 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 following Vent system chart 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 chart. 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 chart provides venting requirements that will help achieve best drying performance. 4 Rigid metal 5 Rigid metal 80 ft. (24.4 m) 70 ft. (21.3 m) Install Vent System 1.
