Example vent system
NOTE: Flexible vent is not recommended. Flexible vent creates
back pressure and air turbulence that greatly reduce
performance.
Determine Range Blower Setting
This cooktop is equipped with a dual range blower. It is shipped
from the factory in the low range for most installations. If the
equivalent duct length exceeds 30 ft (9.1 m), it must be converted
to high range. Do not convert the blower to high range for shorter
lengths; this will cause excessive noise and conditioned air loss.
Convert blower before installing into countertop if necessary.
To Convert to High Range:
1. Using 2 or more people, place cooktop on floor with front
edge and plenum down.
2. Remove the four acorn nuts (A) that attach the blower motor
assembly to the blower exhaust scroll.
3. Remove the blower motor assembly (B) from the blower
exhaust scroll (E).
4. Slowly reach in the blower exhaust scroll opening and
remove the snap ring (C).
5. Gently remove the restrictor ring (D).
6. Place the motor assembly back on the studs of the blower
exhaust scroll.
7. Reattach the four acorn nuts to secure the blower motor
assembly back to the blower exhaust scroll.
Electrical Requirements
If codes permit and a separate ground wire is used, it is
recommended that a qualified electrical installer determine that
the ground path and wire gauge are in accordance with local
codes.
Check with a qualified electrical installer if you are not sure the
cooktop is properly grounded.
