Venting Methods
This hood is factory set for venting through the roof (vertical
discharge) or wall (horizontal discharge). A 8" (203 mm)
round duct system is needed for installation (not included).
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, the hood can be used in the non-vented
(recirculating) version, using the recirculating kit . Fumes
and vapors are recycled through the round grid.
See optional accessories section.
