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.
