4 PREPARING THE COUNTERTOP

accommodate the cooktop and the vent. Countertops
with a rolled front edge and backsplash may not
provide the flat surface area required.
Clearance between inside front of cabinet and rear
of countertop cutout must be 20
accommodate cooktop depth.

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 6".
• 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.
