INSTALLATION PREPARATION (Cont.)
6. 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:
•
to eliminate as much of the corrugation as possible.
7. PREPARE FOR DUCTWORK
in a variety of ways depending on the kitchen layout.
IMPORTANT: The downdraft air discharge outlet
accordingly.
Typical duct arrangement countertop series.

overhang
Peninsula or island
To maximize the ventilation performance of the vent
system:
1. Minimize the duct run length and number of
transitions and elbows.
2. Maintain a constant duct size.
3. Seal all joints with duct tape to prevent any leaks.
