Do not use a plastic vent.

Do not use non-metal flexible vent,
metal vent that is smaller than four
inches in diameter or exhaust hoods with
magnetic latches.
The dryer must be exhausted outdoors.
Do not exhaust dryer into a gas vent,
chimney, wall, ceiling, or concealed
space of a building.
Do not install flexible vent in enclosed
walls, ceilings or floors.
If using an existing exhaust system, clean
lint from entire length of exhaust system.
Make sure exhaust hood is not plugged
with lint.
The exhaust system should be inspected

Four-inch metal exhaust vent is required.
Plan installation to use the fewest
number of elbows and turns.
Metal flexible vent must be fully
extended and supported when the
dryer is in its final position. DO NOT
KINK OR CRUSH THE VENT. The metal
flexible vent must be completely
open to allow adequate exhaust air
to flow.
Allow as much room as possible
when using elbows or making turns.
Bend vent gradually to avoid kinking.
Remove excess flexible vent to avoid
sagging and kinking that may result in
reduced air flow.
Exhaust outlet is located at the
center of the bottom dryer back.
The exhaust vent can be routed up,
down, left, right, behind the dryer or
straight out the back of the dryer.
Maximum length of exhaust system
depends upon the type of vent used,
number of elbows and type of
exhaust hood. The maximum length
for both rigid and flexible vent is
shown in the chart.
