Makeup Air
Local building codes may require the use of makeup air systems
when using ventilation systems greater than specified CFM of
air movement. The specified CFM varies from locale to locale.
Consult your HVAC professional for specific requirements in
your area.
Venting Methods
This canopy hood is factory set for venting through
the roof or wall.
A 6" (15.2 cm) round vent system is needed for installation
(not included). The hood exhaust opening is 6" (15.2 cm) round.
NOTE:
Flexible vent is not recommended. Flexible vent
creates back pressure and air turbulence that greatly
reduce performance.
Vent system can terminate either through the roof or wall.
To vent through a wall, a 90° elbow is needed.
Rear Discharge
A 90° elbow may be installed immediately above the hood.
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.
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 ft (1.5 m)
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).
1 – 90° elbow
= 5 ft (1.5 m)
1 – wall cap
= 0 ft (0 m)
8 ft (2.4 m) straight
= 8 ft (2.4 m)
Length of system
= 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 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 120 volt, 60 Hz., AC only, 15-amp, fused electrical
circuit is required.
■
If the house has aluminum wiring, follow the
procedure below:
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
on the rear wall of the range hood.
■
Wire sizes must conform to the requirements of the 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.
