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, tting a charcoal lter and the deector. Fumes and
vapors are recycled through the top grille.
Roof venting Non-vented (recirculating)
NOTE: Wall venting can be an option for 2-story homes.
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.
Vent Piece 6" (15.2 cm) Round
45° elbow 2.5 ft
(0.8 m)
90° elbow 5.0 ft
(1.5 m)
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).
1 - 90° elbow = 5 ft (1.5 m)
1 - wall cap = 0 ft (0.0 m)
8 ft (2.4 m) straight = 8 ft (2.4 m)
System length = 13 ft (3.9 m)
Electrical Requirements
Observe all governing codes and ordinances.
Ensure that the electrical installation is adequate and in
conformance with National Electrical Code, ANSI/NFPA 70
(latest edition), or CSA Standards C22.1-94, Canadian Electrical
