The electric 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
1 Batterymarch Park
Quincy, Massachusetts 02269-9101
The ground terminal on the hood must be connected •
to a grounded, metallic, permanent wiring system or
grounding conductor installed by a licensed electrician.
Do not ground the appliance or appliance wiring to a •
gas pipeline or to the neutral (white) power supply wire.
Do not install a fuse in the neutral or ground circuit.•
Connect the hood directly to an electrical junction box. •
Hard-wire the hood according to local code directly to
a dedicated three wire grounded, single phase circuit
rated at 120 Vac 60 Hz, 15 Amp.

Planning the Installation
WARNING
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.
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 manufacturer’s recommendation for these devices and consult NFPA and
ASHRAE recommendations.
Failure to install a remote blower or proper duct work •
may result in a back draft and/or the insufficient venting of smoke and fumes.
DO NOT• install an additional in-line or external blow-
er 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 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. The blower assembly
can be rotated to accommodate venting (and wiring)
through the top A or the back B .
A
B
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 require to support the duct weight.
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.
On dual exhaust models, the two 8” exhausts may be •
merged into one 10” duct using Dacor transition kit
AHT10. See page 16 for details.
Calculating the Maximum Duct Run Length
The maximum straight duct length for the hood is determined by the type of duct used. See the chart below.
DUCT SIZE MAXIMUM DUCT RUN
8” round 60 feet
10” round 50 feet
3¼” X 10” rectangular 50 feet
For each elbow and transition added to the duct work, a
certain number of feet must be subtracted from the maximum duct run 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 the maximum duct run above.

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,
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”
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 cross-sectional area
than the recommended types above.

Preparing for Installation
Verify the Package Contents
Unpack the parts box and verify that all parts have been
included according to the parts list on page 5. If any item
is missing or damaged, please contact the dealer immediately. Do not install a damaged or incomplete appliance.
Make sure you have everything necessary for proper installation before proceeding.
Mounting Location Preparation
WARNING
The electrical service to the range hood should be •
installed only by a licensed electrician.
Observe all governing codes and ordinances during •
site preparation and installation. Contact your local
building department for further information.
Failure to properly anchor the hood to the wall may •
result in personal injury due to the unit falling off the
wall.
To avoid an electric shock hazard and property dam-•
age, locate electric wires and water pipes and avoid
drilling or cutting in the vicinity.
Use the temporary mounting brackets only to hold •
the hood in place until permanent anchoring is
installed.
Temporary mounting brackets, and the •
screws and anchors to hold them in place
during installation are provided with the
hood. Two anchors and screws are used
per bracket.
Determine the number, size and type of •
anchors required to attach the hood permanently to the
wall and/or the cabinets based on the type of installation and the weight chart on page 3.
Make sure the mount-•
ing surface is properly
reinforced to handle the
full weight of the hood.
If mounting the unit to a
drywall or plastered surface, install a reinforced
mounting block between
the studs behind all hood
mounting locations. You
may attach screws directly
to the studs and cabinets
if they line up with the
mounting holes in the back
and top of the hood. If
mounting the hood to brick
or masonry, select anchors
capable of holding the full
weight of the hood.
Electrical Service Installation
WARNING
The electric service to the range hood should be installed
only by a licensed electrician.
Install a junction box in the vicinity of the hood electrical access holes according to local codes. Install it either
behind or above the hood. The diagram below shows suggested locations.
Drill 7/8” holes in the wall or cabinet as necessary to allow
the wiring to pass through into the hood. See page 4 for
hole locations.

Hood
Location
Duct Cutout
Using a pencil, draw the vertical center line for the 1.
range hood on the wall. Extend the line down 10” (25.4
cm) from where the top of the hood will be located.
The center line for the hood is usually halfway between
the cabinets at the installation location or the same as
the center line of the cooktop or range. The line will be
used to line up the mounting brackets during installation.
Locate the center lines for the duct cutout(s) according 2.
to the dimensions on page 4. For installations venting
through the top of the hood, use the top dimensions to
locate the center lines on the ceiling or cabinet bottom.
For installations venting through the back of the hood,
use the back dimensions to locate the center lines on
the back wall. See the diagrams on the right.
Cut a hole for the duct to pass through 11” (28 cm) in 3.
diameter. Center it on the center lines. Dual exhaust
models require two (2) holes.
