Recommended
ductwork length
Use 3-l /4" x 10" or 7" ductwork
with a
m'aximum
length
of 26 feet for ductwork
system. For best performance,
use no more
Wan three 90" elbows. To calculate
the
length
of system you need, add the
equivalent
feet for each ductwork
piece
used in the system. See the following
examples.
Ductwork
needed
for insfallofion
is not
included.
Wall or roof caps used must have
backdrafl
damper.
Determine
which
outside
venting
method
needs to be used NOTE: If a non-vented
(recirculating)
installation
is desired,
follow
instructions
on Panel D.
The length
of the ductwork
and number
of
elbows should be kept to a minimum
to
provide
efficient
performance.
The size of
the ductwork
should be uniform.
Do Not
install two elbows together.
Use duct tape
to seal all joints in the ductwork
system.
Ductwork
can terminate
either through
the
roof or wall. Use caulking
to seal exterior
wall or roof opening
around
exhaust
hood.
For the most efficient
and quiet operation,
it
is recommended
that the range be vented
vertically
through
the roof through
7" round
ductwork.
Figures l-4 show common
venting
methods
and what types of materials
are needed.
