NOTE: The igure does not represent all conigurations or installation methods. The image is to be used as a guide ONLY.
NOTE: Flexible duct is not recommended. Flexible
ductwork creates back pressure and air turbulence that
greatly reduce performance.
Vent system can terminate either through the roof or wall.
Always install a metal vent cover where the ductwork exits
the house.
For Non-Vented (recirculating) Installations
If it is not possible to vent cooking fumes and vapors to the
outside, this range hood can be used in the non-vented
(recirculating) version, using the recirculating kit (sold
separately). Fumes and vapors are recycled through the
grid.
See optional accessories section.
