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 a Recirculation Kit (which includes charcoal filters
and a deflector). To order, see the “Assistance or Service”
section.
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 recommended
vent length of 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:

1. Connect a section of solid copper wire to the pigtail
leads.
2. Connect the aluminum wiring to the added section
of copper wire 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 the appliance as specified on the model/serial/rating plate.
The model/serial/rating plate is located behind the left filter
