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 a charcoal filter and the deflector. Fumes and
vapors are recycled through the top grille. See the "Assistance
or Service" section for information on ordering.
The ducting from this fan to the outside of the building has a
strong effect on the air flow, noise and energy use of the fan.
Use the shortest, straightest duct routing possible for best
performance, and avoid installing the fan with smaller ducts than
recommended.
Insulation around the ducts can reduce energy loss and inhibit
mold growth. Fans installed with existing ducts may not achieve
their rated airflow.

*The recirculating version are neither Energy Star nor VI certified.
Ensure duct joints and exterior penetrations are sealed with
caulk or other similar material to create an air-tight path and to
minimize building heat loss and gain and reduce the potential for
condensation.
Place/wrap insulation around duct and/or fan to in order to
minimize possible condensation buildup within the duct, building
heat loss and gain
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.

6" (15.2 cm) Round
45° elbow
2.5 ft (0.8 m)
90° elbow
5 ft (1.5 m)
Maximum equivalent vent length is 35 ft (10.7 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 Code, Part 1 and C22.2 No. 0-M91 (latest edition),
and all local codes and ordinances.
If codes permit and a separate ground wire is used, it is
recommended that a qualified electrician determine that
the ground path is adequate.
A copy of the above code standards can be obtained from:

procedure below:
Connect the aluminum wiring using special connectors
and/or tools designed and UL listed for joining copper to
aluminum.
Follow the electrical connector manufacturer's recommended
procedure. Aluminum/copper connection must conform with
local codes and industry accepted wiring practices.
Wire sizes and connections must conform with the rating of
