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%" in
order to 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.
