DUCTING RECOMMENDATIONS
Proper performance is dependent upon proper ducting.
MAKE-UP AIR: Local building codes may require the use
of make-up air systems when using ducted ventilation
systems greater than specifi ed CFM of air movement.
The specifi ed CFM varies from locale to locale. It is the
A
D
B
E
responsibility of the owner and the installer to determine if
additional requirements and/or standards apply to specifi c
installations.
DO NOT USE FLEXIBLE DUCT; it creates back pressure/
air turbulence and reduces performance.
C
Always install a metal vent cover where the ductwork
exits the house.
G
HD1101
The 6 basic discharge connections, left, right, rear, front, down and
recirculation can be achieved through A to G with the optional parts listed.
1. The downdraft blower system is designed for use with 8” (203 mm)
round ductwork using a fl exible blower or 6” (152 mm) round ductwork
using an inline or remote blower. (Purchase blowers separately.):
Seven (7) different discharge connections are available - A to G, below:
A = 8” (203 mm) Round, Left Discharge out of Flex Blower
B = 8” (203 mm) Round, Right Discharge out of Flex Blower
C = 8” (203 mm) Round, Down Discharge out of Flex Blower (Electrical
Panel to be mounted remotely)
D = 1-7/8” x 19” (48 mm x 483 mm), Left Discharge out of Housing to
Remote Blower or Flex Blower in remote location. Use 1-7/8” x 19”
(48 mm x 483 mm) to 6” (152 mm) or 8” (203 mm) round transition
or 1-7/8” x 19” (48 mm x 483 mm) ductwork as appropriate.
E = 1-7/8” x 19” (48 mm x 483 mm), Right Discharge out of Housing to
Remote Blower or Flex Blower in remote location. Use 1-7/8” x 19”
(48 mm x 483 mm) to 6” (152 mm) or 8” (203 mm) round transition or
1-7/8” x 19” (48 mm x 483 mm) ductwork as appropriate.
F = 1-7/8” x 19” (48 mm x 483 mm), Rear Discharge out of Housing to
Remote Blower or Flex Blower in remote location. Use 1-7/8” x 19”
(48 mm x 483 mm) to 6” (152 mm) or 8” (203 mm) round transition or
1-7/8” x 19” (48 mm x 483 mm) ductwork as appropriate.
G = 1-7/8” x 19” (48 mm x 483 mm), Down Discharge out of Housing to
Remote Blower or Flex Blower in remote location. Use 1-7/8” x 19”
(48 mm x 483 mm) to 6” (152 mm) or 8” (203 mm) round transition or
1-7/8” x 19” (48 mm x 483 mm) ductwork as appropriate.
2. For best performance: Choose the ducting option which allows the
shortest length of ductwork and a minimum number of elbows and
transitions. Check location of fl oor joists, wall studs, electrical wiring
or plumbing for possible interference.
NOTE: The manufacturer is not responsible for performance complaints
attributable to the duct section.
The device achieves its optimum performance by means of a short,
straight exhaust air duct and as large a pipe diameter as possible.
The optimum extraction performance is not achieved and fan noise is
increased if exhaust air ducts are long and rough and if there is a large
number of duct bends or diameters less than 6”.
The pipes or hoses for laying the exhaust air line must consist of non-
combustible material.
Seal the connection points of the ducts appropriately.
Ductwork must vent outside, not into attic spaces for example, unless
the available ‘Non-duct Recirculation Kit’ is used.
F
COLD WEATHER installations should have an additional
backdraft damper installed to minimize backward cold
air fl ow 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.
For safety reasons, ducting should vent directly outdoors
(not into an attic, underneath the house, into the garage
or into any enclosed space). In gas cooking application,
the unit cannot be used in conjunction with a recirculation
unit.
BOSCH
equivalent duct.
Plan cabinetry
For left, right, or rear exhaust:
Allow at least 18” (457 mm) for transition and elbow or
blower.
For left / right exhaust:
A 30” (762 mm) deep cabinet is recommended to align
properly with fl ex blower. Flex blower can be mounted to
rear cabinet wall or to a platform / frame (not provided)
on the base of the cabinet fl oor. (See fl ex blower
instructions.)
Cabinet depths of 24” (610 mm) to 30” (762 mm) are
required - depending on the type of cooking appliance.
For some applications, gas or electrical connections will
need to be moved or routed around downdraft unit.
For gas cooktop installations make sure that a minimum
27 square inch (174 cm²) opening is provided in the
toe-kick and cabinet base. Inadequate ventilation of the
cabinet below the cooktop may result in fl ame outage
when operating the fan on higher speeds.
NOTE: A cooktop sealing kit must be purchased for gas
applications. The kit includes hole covers for the toe-kick
and cabinet base, as well a a trim seal for the cooktop.

INSTALLATION
Take measurements
1. Refer to the cooktop installation instructions for
dimensions of cooktop, countertop cut-out, and
cabinet requirements. However, it is recommended
that oversized cabinets be used for easier installation.
Custom island designs need to account for deeper
cabinets, especially when mounting the blower behind
the downdraft. You must also plan for an access door.
Pay special attention to the areas of potential interference
highlighted below. A countertop with (A) a raised lip and/or
(B) a backsplash may not allow enough fl at countertop for a
proper installation. Note that a minimum of 2-7/8” (73 mm)
of fl at countertop is required behind cooktop (C) and that a
minimum of 2-7/8” (73 mm) is necessary between the back
edge of the cooktop and the inside of cabinet back (D).

Dimension “BT” is thickness of
the backsplash that provides
1/2” (13 mm) clearance
between the vent and the
backsplash. Any backsplash
with a curved radius where it
meets the counter will require
additional clearance. Thicker
backsplashes may be used
by increasing the counter and
cabinet depths.
Set the cooktop into the
coutertop opening so that
the back edge of the cooktop
overlaps the leading edge of
the downdraft.
