Installation

General Information
1. For the most efficient air flow exhaust, use a straight
run or as few elbows as possible.
Blower Cord Connector
Connector Access Panel
2. Do not use flex ducting.
3. COLD WEATHER installations should have an additional
backdraft damper installed to minimize backward cold
air flow and a nonmetallic thermal break to minimize
conduction of outside temperatures as part of the
ductwork. The damper should be on the cold air side of
the thermal break. The break should be as close as
possible to where the ducting enters the heated portion
of the house.
4. Hood installation height above cooktop is the user’s
preference. The lower the hood above the cooktop, the
more efficient the capturing of cooking odors, grease,
and smoke. This hood has been approved for installations
as low as 24 inches and as high as 36” above the cooktop.
The lower height may be inconvenient for tall people
and large cooking vessels. Consequently, Bosch
recommends the hood be installed 30”-36” above the
countertop.

6. Make-Up Air: Local building codes may require the use
of make-up air systems when using ducted ventilation
systems greater than specified CFM of air movement.
The specified CFM varies from locale to locale. Consult
your HVAC professional for specific requirements in your
area.

2. Remove Knockout
Remove the appropriate blower duct knockout. For
horizontal discharge, remove the knockout in the back
wall of the hood. For vertical discharge, remove the
knockout in the top of the hood.

3. Install Internal Blower (DAH95 models only)
If your hood is already equipped with a blower, or you
will be using a remote blower, proceed to
Step 4: Install Transition (next page).
1. Remove rear filter rail.
2. Remove blower control wire cover.
3. Remove J box.

are 15 3/4” from the center line (See Figure 5).
4. Install Transition
4. Place the hood.
For internal blower installation, install the 7”
transition (included) to connect to 7” ducting. If 7”
ducting is not available, 8” ducting may be used. In
this instance, an additional 7-8” transition must also be
used (not included).
5. Tighten the screws.
For remote blower applications, 10” ducting is
required. In this instance, a 7”-10” transition must
also be used.
Attach the transition with 4 #8 sheetmetal screws
(included) and seal connection with duct tape.

The DAH model hood can be mounted through the
back wall or through the top. See General Information,
page 1, for suggestions for hood height.
Once the preferred height is determined, locate the
centerline (left to right) of the cooking appliance.
15-3/8"

1. From the centerpoint of the cooking appliance,
measure up to the preferred height. Measure up an
additional 9” to locate the centerline of the screw
holes (see Figure 4).

2. Install toggle bolts through drywall leaving 1/4” of
the bolt exposed.
Install one togglebolt 11 1/2” to the left of the
centerline and one togglebolt 11 1/2” to the right
of the centerline. These are the only installation
points for the 30” hood. See Figure 4
For the 36” hood, there are 2 additional installation
points. These are also at the centerline height, but
are 15 3/8” from the centerline in each direction.
See Figure 4.
3. Place the hood by sliding the mounting holes in the
hood over the bolts.
4. Tighten the bolts.
Top Mount
1. Install the hood flush against the back wall.

2. Identify the centerline on the mounting surface
(underside of cabinet).

3. Place the hood and install the drywall screws
through the mounting holes.

centerline in both directions at the following
depths:

The 36” hood also requires 3 additional screws, at
the same depths, on each side (total of 6). These
