Select the route that will provide
the straightest
and most direct path outdoors.
Plan the installation
to use the fewest
number
of elbows
and turns.
When using elbows or making turns,
allow
as much
room
as possible.
Bend vent gradually
to avoid
kinking.
Determine vent length
The maximum
length
of the exhaust
system
depends
upon:
. the type of vent (rigid
or flexible
metal).
l
the number
of elbows
used.
. side or bottom
exhaust.
Side or bottom
exhaust
adds a 90" turn inside the dryer. To determine
maximum
exhaust
length,
add one 90" turn to the
chart.
1. See the exhaust
vent length
chart that matches
your type hood for the maximum
vent lengths
you
can use.
Do not use vent runs longer than specified
in
exhaust vent length
charts.
Exhaust
systems
longer
than specified
will:
-
accumulate
lint creating
a potential
fire
hazard.
-
shorten
the life of the dryer.
-
reduce
performance,
resulting
in longer
drying
times and increased
energy
usage.
2. Determine
the number
of elbows
you will need.
3. In the column
listing
the type of metal vent you are
using (rigid
or flexible),
find the maximum
length
of metal
vent on the same line as the number
of
elbows.
4. Determine
the number
of 4" clamps
you will need.
