Installation Specifications
Electrical Specifications
When planning new
duct work, always look
for the shortest, most
direct route to the outside. Venting can be
done through the roof
or directly through the
back wall to the outside as shown.
Make sure duct work
does not interfere with
floor joists or wall
The electrical service to the range hood should be
installed only by a licensed electrician.
It is the owner’s responsibility to ensure that the electrical
connection of this appliance is performed by a qualified
electrician. The electrical installation, including minimum
supply wire size and grounding, must be in accordance
with the National Electric code ANSI/NFPA* (or latest
revision) and local codes and ordinances.
* A copy of this standard may be obtained from:
National Fire Protection Association

Quincy, Massachusetts 02269-9101
Connect the hood to a junction box supplied by a 120
Vac, 60 Hz dedicated, grounded, 3-wire (hot, neutral,
ground) circuit protected by a 15 Amp. circuit breaker
or time delay fuse. It must be installed a minimum of 17
inches above the bottom of the hood.
Calculating the Maximum Duct Run Length
The maximum straight duct length for the hood is 50 feet.
To determine the actual maximum duct run, subtract the
equivalent length of each elbow, transition and cap from
50 feet.
Planning the Duct Work
• To reduce the risk of fire and to properly exhaust air,
be sure to duct air outside the house or building. Do
not vent exhaust air into spaces within walls or ceilings or into attics, crawl spaces or garages.
• To prevent combustion by-products smoke or odors
from entering the home and to improve efficiency,
tape all duct joints securely.

* The equivalent lengths of roof and wall caps vary with
model and configuration. For equivalent length, contact
the manufacturer or a qualified HVAC specialist.
Duct Work Design Tips
Wherever possible, reduce the number of transitions
and turns to as few sharp angles as possible. Two
staggered 45° angles are better than one 90°.
• DO NOT install an additional in-line or external
blower to increase the length of the duct run. Even
small differences between blower air flow rates can
greatly reduce the air draw of the hood.
Keep turns as far away from the hood exhaust as
possible, and as much space between bends as possible.
For best performance, use round duct instead of rectangular, especially when elbows are required.
If multiple elbows are used, try to keep a minimum of
24 inches straight duct between them. Avoid “S” or
“back to back” use of adjacent elbows.
In regions where the weather gets extremely cold,
use thermal breaks, such as a short section of
non-metallic duct, to avoid indoor heat loss. Locate
the break as close as possible to the outside pass
through point.
Do not use flexible metal duct.
DO NOT use duct work that is smaller in crosssectional area than the recommended size duct (8”
• Do not exhaust more than one vent into a single
duct run.
All duct work materials (including screws and duct
tape) must be purchased separately by the customer.
The hood exhaust connects to an 8-inch round duct.
You can increase the duct size over the duct run if
desired. To prevent a back draft, never decrease the
duct size over the run. If existing duct work is smaller
than 8 inches in diameter, remove it and replace it
with 8-inch duct work.
Do not rely on tape alone to seal duct joints. Fasten
all connections with sheet metal screws and tape all
joints with certified silver tape or duct tape. Use sheet
metal screws as required to support the duct weight.
To prevent back-drafts, a damper at the duct outlet
may also be required.
Installation Instructions
• Do not install the range hood unless the power supply provided meets the required Electrical Specifications
(see page 4).
• Observe all governing codes and ordinances during installation. Contact your local building department for further information.
• A qualified technician must complete the installation of this built-in appliance. The owner is responsible to make
sure the hood is properly installed.
• To avoid an electric shock hazard and property damage, locate electric wires and water pipes and avoid drilling
or cutting in the vicinity.
