Special provisions for mobile home installations:
The exhaust vent must be securely fastened to a noncombustible portion of the mobile home structure and must not terminate beneath the mobile home. Terminate the 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 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.
