Preparation and Setup

Meeting Installation Requirements

WARNING

Observe all governing codes and ordinances during
planning and installation. Contact your local building
department for further information. Use only ductwork
deemed acceptable by state, municipal and local codes.

WARNING

To reduce the risk of personal injury caused by reaching
over a hot appliance, cabinet storage space located
directly above the range should be avoided.

IMPORTANT

See the diagram for minimum installed distance from
the hood to the cooktop surface. The minimum specified
distance may be higher for the particular range or
cooktop in use. Check the manufacturers specifications
for the cooktop or range.

• The hood must be as wide as the cooktop surface or
wider.

• Plan the installation so that all minimum dimensions
are met or exceeded.

• Dimensions given are minimum clearances, unless oth­erwise noted.

• All contact surfaces between the hood and any cabine­try or walls must be sturdy, solid, and at right angles.

• Install the hood and cooking appliance(s) so that they
can be removed if service is required.

Preparation and Setup

Planning the Ductwork

WARNING

• To prevent combustion by-products, smoke or odors
from entering the home and to improve efficiency, tape
all duct joints securely.

• 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 ductwork
may result in a backdraft and/or insufficient venting of
smoke and fumes.

• 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.

CAUTION

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.

WARNING

During duct installation, make sure there are no
obstructions that keep the damper flaps on the top of the
hood from opening.

• Local building codes may require the use of makeup air
systems with ventilation systems that move air greater
than the specified movement rate (CFM).

The specified rate varies based on locale. Consult a
qualified HVAC specialist when designing the system
for the requirements in your area and to assure optimal
performance.

• All ductwork materials (including screws and foil tape)
must be purchased separately.

• Make sure ductwork does not interfere with floor joists
or wall studs.

• Fasten all joints with sheet metal screws and seal with
certified duct tape or foil tape.

• Two 8-inch exhausts may be merged into one 10-inch
duct using Dacor transition kit AHT10. See page 18
for details.

B

Vent Direction Options

The fan factory default direction is through top A of the
hood. However, the fan can be rotated to vent through the
rear B of the hood.

When planning new ductwork, always find the shortest,
most direct route to the outside.

Duct Length Calculation Table

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-inch Round 60 feet

10-inch Round 50 feet

3 1/4-in x 10-in Rectangular 50 feet

For each elbow and transition added, a certain length must
be subtracted from the maximum duct run to compensate
for wind resistance.

To determine your maximum length:

1. Start with the total max. length of your duct run, then

2. Subtract all of the ductwork equivalent lengths (see
chart below).

Preparation and Setup

Ductwork Tips

Wherever possible, reduce the number of transitions, turns,
and sharp angles. Two staggered 45° angles are better
than one sharp 90° angle.

Keep turns as far away from the hood exhaust as possible,
and keep as much space between any 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 at least 24 inches of
straight duct between each elbow.

Avoid using “S” or back-to-back adjacent elbows.

In extremely cold weather regions, use thermal breaks, i.e.,
short sections 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 ductwork that is
smaller than what is advised in the tables.

• 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 backdraft, never decrease the duct size
over the run. If existing ductwork is smaller than 8
inches in diameter, remove it and replace it with 8-inch
ductwork.

• Do not rely on tape alone to seal duct joints. Fasten
all connections with sheet metal screws, and tape all
joints with certified duct tape or foil tape.

• Use sheet metal screws as needed to support the
weight of the ducting.

• To prevent backdrafts, a damper at the duct outlet may
also be required.

10

Preparation and Setup

WARNING

• The electricity 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 dam­age, locate electric wires and water pipes and avoid
drilling or cutting in the vicinity.

• Use the temporary holding brackets only to hold the
hood in place until permanent anchoring is secured.

Preparing the Mounting Location

Holding brackets and hardware are provided to temporarily
hold the hood in place while you permanently fasten the
hood to the wall.

The illustrations below show the purpose of the holding
brackets and the support behind the wall.

1. If mounting the hood to brick or masonry, select
anchors capable of holding the full weight of the hood.

2. Make sure the mounting surface is properly reinforced
to support the full weight of the unit.

• If mounting the unit to drywall or a plastered surface,
install a reinforced mounting block between the studs.

• Attach screws directly to the studs and cabinets if they
align with the mounting holes in the back and top of the
hood.

Installation Instructions

Marking the Centerlines

These measurements and marks are for centering and
leveling the hood, marking the duct cutouts, and installing
the holding brackets.

The holding brackets temporarily hold the hood while you
mount it permanently into place.

Have a marking tool, tape measure, and level ready.

1. Position the hood in the same orientation as it will be
when installed. (For example, if it is a top vent installa­tion, set the hood with the vents on top.)

2. Measure the distance from the edge of the hood to the
center of the exhaust port.

3. Transfer that measurement to the wall (for a rear vent),
or overhead (for top vent). Measure the X and Y axis to
find the centerline.

4. Extend the line down 10 inches (25.4 cm).

5. Cut a hole that is 1 inch larger than the duct. Dual
exhaust models require two (2) holes.

Orientating the Blower(s)

It is imperative that the fan(s) are installed in the correct
orientation.

To do this, make sure the cable I/O port is against the
back of the hood. Confirm the orientation is correct by
comparing it with the figures on the right.

11. Lay the fan over the exit vent with this specific

placement:

When facing the inside of the hood,

• The cable I/O port must be on the right, and

• The cable I/O port must be against the back of

the hood.

Using the Dual to Single
Transition Kit# AHT10

On dual exhaust models, the two 8-inch duct exhausts can
be transitioned into one 10-inch duct.

Assemble the Dacor transition kit # AHT10 before hanging
the hood. This transition kit fits over the top or rear ventila­tion exits.

IMPORTANT:

DTHP3010, 3610, 4810 models
CANNOT vent through the rear ducts.

Preparing the AHT10

1. Create a lip around the transition kit by bending the
bottom edges backward at right angles to create a 3/4”

flange around the base.

Bending the Flange for:

• Rear Vent Configuration

Hanging the Range Hood

WARNING

Hanging the range hood requires two people. Do not attempt to lift the hood without assistance.

When hanging the hood, be careful not to scratch or dam­age the hood.

1. Remove the plastic film from the hood.

There are hanging slots in the back of the hood a few
inches from the top. The holding brackets on the wall
engage here and temporarily hold the hood in place.

2. Lift the hood up and catch holding brackets in the
hanging slots in the back of the hood (see figure
Hanging the Hood).

3. Adjust the hood into its final position.

4. Mark the spot by drawing in a mounting hole in the
back of the hood (see figure Hanging and Mounting
Slots ). This is where a screw will hold the hood to the
wall stud or (concrete) anchor.

5. Mark the top of the hood if the configuration calls for
the hood to be secured at the top.

6. Remove the hood from the wall.

7. Drill the pilot or anchor holes. If using anchors, insert
them into the anchor holes.

8. Reattach the hood to the holding brackets.

9. Adjust the hood into its final position and fasten it into
place:

Insert the fasteners through the mounting slots in the
back and top of the hood and into the studs, mounting
blocks, or anchors.

Hardwiring the Hood

WARNING

• To avoid electric shock or fire hazard, make sure that

power to the hood power supply line is turned OFF at
the fuse box or circuit breaker before connecting the
electrical wiring.

• Miswiring the hood electrical wiring can create an

electric shock or fire hazard and could damage the
hood’s electrical system. See page 25.

• Do not ground the wires to the neutral (white) wire.

Connect the ground wire to a separate, properly
grounded ground-wire installed by a licensed electri­cian.

• Make sure that all wire used is the correct gauge and

capable of handling the total connected loads and
meeting all codes.

1. Shut the power OFF at the circuit breaker or fuse box.

2. Feed the cable assembly through the hood.

3. Connect the cable assembly to the fan.

4. Connect the hood wiring to an electrical junction box
on a dedicated circuit.

5. See next page for instructions on how to ground the
hood to a cold water pipe.

• Refer to Wire Diagrams on page 25.

Inserting Light Bulbs

Make sure dimmable bulbs are used. The electronic board
was designed for dimmable lights and using non-dimmable
types will cause damage and faulty performance.

Shut the main circuit breaker OFF while inserting new or
while changing bulbs. If an electrical short occurs while the

main power circuit is ON, significant damage can occur.

Follow the diagram to the right for instructions.

1. Attach the suction cup to the lens of a dimmable light
bulb. (Both are supplied parts.)

Make sure the bulb faces are clean so the suction cup
can stick.

2. Insert the bulb into one of the light fixtures.

3. Screw it into place and remove the suction cup.
