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 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.
