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, fitting an activated carbon filter and the deflector. Fumes
and vapors are recycled through the top grille.
Calculating Vent System Length
To calculate the length of the system you need, add the
equivalent feet (meters) for each vent piece used in the system.
Maximum equivalent vent length is 35 ft (10.7 m).
Example vent system
The following example falls within the maximum vent length of
35 ft (10.7 m).
