 = Range hoods must be ventilated to the
outdoors, except for non-vented
(recirculating) installations.
u Do not ventilate the range hood into an
attic or other enclosed areas.
m Do not use 4" (10.2 cm) laundry-type wall
m The length of the range hood and the
number of elbows should be kept to a
minimum to provide maximum performance.
For the most efficient and
quiet operation
m Use no more than three 90° elbows.
= Make sure there is a minimum of 24" (61
cm) of straight duct between the elbows if
more than one elbow is used.
m Do not install two elbows together.
m Use clamps to seal all joints in the vent
m The vent system must have a damper. If
the roof or wall cap has a damper, do not
use the damper supplied with the range
m Use caulking to seal exterior walls or roof
openings around the cap.
m The size of the vents should be uniform.
Cold Weather Installations
An additional back draft damper should be
installed to minimize backward cold air flow.
A thermal break should be installed to
minimize conduction of outside temper-
atures as part of the vent system. The
damper should be on the cold air side of the
thermal break.
The break should be as close as possible to
where the vent system enters the heated
portion of the house.
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
state to state. Consult your HVAC
professional for specific requirements in
your area.
Venting Method
This canopy hood is factory set for through
the roof or wall.
A 6" (15.2 cm) round vent system is needed
for installation. The hood exhaust opening is
6" (15.2 cm) round.
To vent through a wall, a 90° elbow is
If exhaust ducting with a diameter of less
than 5.91" (150 mm) or if flat ducting is used,
the noise level of the range hood will
increase and extraction will be less efficient.

To calculate the length of the system you need,
add the equivalent feet (meters) for all vent
pieces used in the system.
Duct Run Calculation:

Vent piece deduction
Recommended maximum run | Duet Run Calcuation example:
One roof cap, twa 90” elbow, and one 45° elbow used:
Oft + 91 + 9 + 311 = 23ft used.

Observe all governing codes and ordinances.
Ensure that the electrical installation is adequate
and in conformance with the National Electrical
Codes, ANSI/NFPA 70 (latest edition), or CSA
Standards C22.1-94, Canadian Electrical Code,
Part 1 and C22.2 No. 0-M91 (latest edition), all
local codes, and ordinances. If codes permit and
a separate ground wire is used, itis
recommended that a qualified electrician
determine that the ground path is adequate.

u À 120 volt, 60 Hz., AC only, 15-amp, fused
electrical circuit is required.
m 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 copper
wire using special connectors and/or tools
designed and UL listed for joining copper to
Follow the manufacturer's recommended
procedure for the electrical connector.
Aluminum/copper connection must conform to
local codes and industry accepted wiring
m Wire sizes and connections must conform to
the rating of the appliance as specified on the
model/serial rating plate. The model/serial plate
is located behind the filter on the rear wall of the
range hood.
