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.
Tape all duct joints securely to prevent combustion
by-products, smoke or odors from entering the home.
Doing so will also improve system efficiency.
Do not exhaust more than one vent into a single duct
Use only duct work constructed of materials deemed
acceptable by state, municipal and local codes.
Range hoods may interrupt the proper flow of
smoke and combustion gases from furnaces, gas
water heaters and fireplaces. To avoid drawing
lethal gases into the home, follow the manufactures
recommendation for these devices and consult NFPA
and ASHRAE recommendations.
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 by the hood.
All contact surfaces between the hood and any cabinets or
walls must be solid and at right angles.
Install the range hood and cooking appliance(s) so that
they can be removed if service is required.
and Install the
All duct work materials (including screws and duct tape)
must be purchased separately by the customer. 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
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.
Do not rely on duct 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 require to support the duct
To prevent back-drafts, a damper at the duct outlet may
also be required.
Make sure duct work does not interfere with floor joists
or wall studs.
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.

Installing the Electrical Connection
The electrical connection box must be:
Connected to a 120 Vac, 60 Hz dedicated, grounded,
circuit protected by a 15 Amp circuit breaker or time
delay fuse.
Located a minimum of 17” (43 cm) above the bottom of
the range hood.
for Installation
Calculating the Maximum Duct Run Length
The maximum straight duct length for the hood is 50
feet. For each elbow and transition added to the duct
work, a certain number of feet must be subtracted from
the maximum straight length to compensate for wind
resistance. To determine the length the duct work cannot
exceed, subtract all of the equivalent lengths of the elbows
and transitions listed below from 50 feet.
Duct Work Equivalent Lengths
90° elbow (8” Dia.)
7 feet
45° elbow (8” Dia.)
3 feet
3 1/4” x 10” to 8” round
4 foot
Wall cap with damper
30 feet
Roof cap
30 feet
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°.
Keep turns as far away from the hood exhaust as
possible, with as much space between each bend as
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” of straight duct between them.
Avoid “S” or “back to back” configurations of adjacent
In regions where the weather gets extremely cold,
thermal breaks, such as a short section of non-metallic
duct, should be used to avoid indoor heat loss. The
break should be located as close to the pass through
point to the outside as possible.
Do not use flexible metal duct.
Do not use duct work that is smaller in cross-sectional
area than the recommended size duct (8” round).
Duct Work Installation
Install all of the duct work, except for the portion that
will be located inside the hood chimney:
1. Determine the vertical center line for the range hood.
The center line for the hood is usually the same as the
center line of the range or cooktop.
2. Using a pencil, mark the vertical center line on the wall
from where the bottom of hood will be located to where
the top of the chimney will be located.
3. Draw a horizontal line 24 inches long at 90° to the
vertical center line where the bottom of the hood will be
located. The minimum allowable distance from the top
of the cooktop to the bottom of the hood is 30”.
4. Install the duct work so that the connection to the hood
will be centered on the hood’s center line. Also allow
for a 1” clearance between the duct work and the wall
where the hood will be mounted. The 1” clearance will
allow room for the chimney mounting bracket on the
