Step 4 Preparing the Countertop Clearance between inside front of cabinet and rear of countertop cutout must be 2@A"in order to accommodate cooktop depth. Min. Step 5A Attach the Blower Transition Duct The blower transition duct is not packed with your cooMop. For all downward duct installations connect to a transition duct with a 6" round standard ductwork. This 31/4"x 10" rectangle to 6" round transition duct is available at your local building supply store. A 1/2" wide flat area is required around the edge of opening for support of the unit. The cooktop unit must be level and sit squarely into countertop opening. Carefully cut countertop opening according to the dimensions shown in the illustration. Be sure that opening is cut squarely, with sides parallel to each other and rear exactly perpendicular to sides. 20%" Step 5 Preparing for Ductwork NOTE: Ductwork MUST be vented to outside. DO NOT vent into a wall, ceiling, crawlspace, attic or any concealed space. Cut hole in cabinet wall or floor as appropriate for your installation.

Good alignment without use of flexible ducting is best. NOTE: • Do not exceed the maximum recommended offset of 3". • Do not allow the flexible ducting to kink or collapse. • Do stretch the flexible ducting as much as possible to eliminate as much of the corrugation as possible. =g Transiti 3" Max.

Blower
to Ductwork
Alignment
In general,
the
use
of flexible
ducting
is
discouraged
because
it can
cause
severely
restricted
airflow.
However,
if the
blower
outlet
and
the
floor
or wall
duct
location
do
NOT
align
well,
then
flexible
METAL
ducting
can
be used
to
adapt
to
an offset.
Good
alignment
without
use
of flexible
ducting
is best.
NOTE:
•
Do
not
exceed
the
maximum
recommended
offset
of 3".
•
Do not allow the
flexible
ducting
to kink or
collapse.
• Do stretch
the flexible
ducting
as much
as possible
to eliminate
as much
of the
corrugation
as possible.
