For Best Performance:
Do not install 2 elbows together.
Use no more than three 90° elbows.
If an elbow is used, install it as far away as possible from the
hood's vent motor exhaust opening.
Make sure there is a minimum of 24" (61 cm) of straight vent
between the elbows if more than one elbow is used.
The length of vent system and number of elbows should be
kept to a minimum to provide efficient performance.
Cold Weather Installations
An additional backdraft damper should be installed to minimize
backward cold air flow and a nonmetallic thermal break installed
to minimize conduction of outside temperatures as part of the
vent system. The damper should be on the cold air side of the
thermal break.
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 range hood is factory set for vented installations. Vent
system can terminate through either the roof or wall. A
6" (15.2 cm) round vent system must be used. The vent system
length should not exceed 35 ft (10.7 m).

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
45° elbow 2.5 ft (0.8 m)
90° elbow 5.0 ft (1.5 m)
Example vent system

NOTE: Flexible vent is not recommended. Flexible vent creates
back pressure and air turbulence that greatly reduce
C
performance.

Electrical Requirements

IMPORTANT: Observe all governing codes and ordinances. Save
Installation Instructions for electrical inspector's use.
It is the customer's responsibility to contact a qualified electrical
installer, and to assure 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:
National Fire Protection Association
One Batterymarch Park, Quincy, MA 02269
8501 East Pleasant Valley Road
A 120-volt, 60-Hz, AC-only, 15 amp, fused electrical circuit is
required.
Do not ground to a gas pipe.
