General Information
1. For the most efficient air flow exhaust, use a straight
run or as few elbows as possible.
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.
5. Remote blowers require a five wire installation.
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.
1. Unpack Hood
Pull hood from outer packaging and remove all
packaging materials.
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.
4. With hood standing on its back wall, place blower
in center of hood.
5. Screw 6 screws (3 on each side) through mounting
plates. See Figure 2.
