This appliance must be properly installed and grounded by a qualified technician. Connect only to properly grounded outlet. Refer to Installation Instructions for details.

This appliance is intended for normal family household use only. It is not approved for outdoor use. See the Statement of Limited Product Warranty in the Use and Care Guide. If you have any questions, contact the manufacturer.

Do not store or use corrosive chemicals, vapors, flammables or nonfood products in or near this appliance. It is specifically designed for use when heating or cooking food. The use of corrosive chemicals in heating or cleaning will damage the appliance and could result in injury.

Do not operate this appliance if it is not working properly, or if it has been damaged. Contact an authorized servicer.

Do not repair or replace any part of the appliance unless specifically recommended in this manual. Refer all servicing to a factory authorized service center.

WARNING

Make sure the appliance and lights are cool and power to the appliance has been turned off before replacing the LED (if equipped). Failure to do so could result in electrical shock or burns.

WARNING

Do not use this unit in conjunction with a recirculation unit in gas cooking application.

CAUTION

Grease left on filters can melt and move into the vent and catch fire.

WARNING

Hidden surfaces may have sharp edges. Use caution when reaching behind or under appliance.

WARNING

Unit is heavy and requires at least two people or proper equipment to move and install.

WARNING

Tie long hair so that it does not hang loose, and do not wear loose fitting clothing or hanging garments, such as ties, scarves, jewelry, or dangling sleeves.

WARNING

When the hood is operated in exhaust-air mode simultaneously with a different appliance which also makes use of the same chimney (such as gas, oil or coalfired heaters, continuous-flow heaters, hot-water boilers) care must be taken to ensure that there is an adequate supply of fresh air which will be needed by the appliance for combustion.

This can be achieved if combustion air can flow through non-lockable openings, e.g. in doors, windows and via the air-intake/exhaust-air wall box or by other technical measures, such as reciprocal interlocking, etc.

WARNING

Avoid carbon monoxide poisoning – Provide adequate air intake so combustion gases are not drawn back into the room. An air-intake/exhaust-air wall box by itself is no guarantee that the limiting value will not be exceeded.

NOTE: When assessing the overall requirement, the combined ventilation system for the entire household must be taken into consideration. This rule does not apply to the use of cooking appliances, such as cooktops and ovens.

WARNING

To avoid electrical shock hazard, before installing, switch power off at the service panel and lock the panel to prevent the power from being switched on accidentally.

BEFORE YOU BEGIN

Installation review

This downdraft system can be used to exhaust cooking by-products such as heat, steam, and smoke that may be created while cooking using gas or electric cooktops. With its versatile design, there are six (6) basic discharge options - left, right, rear, front, down and recirculation. It is important to first plan your installation. The purchase of additional accessories to complete the installation may be necessary.

It can be mounted in an island, peninsula, or conventional wall location. The blower (purchase separately) and electrical panel can be mounted to the downdraft unit, inside the cabinet, or in a convenient remote location.

This unit can be easily installed following these basic steps:

Plan the installation.

Cut out the countertop opening. Prepare the downdraft housing.

Cut out the cabinet opening for discharge. Mount the downdraft in the cabinet.

Install gas cooktop seal kit accessory, if applicable. Connect the ductwork and install the blower.

Install downdraft electrical panel, if in remote location.

Install the cooking appliance. Install end caps to downdraft. Check the operation.

NOTE: The high level of air flow of this appliance may effect the gas flame on some types of gas cooktops. This is NORMAL and will cause no harm, but can be corrected by lowering the speed of the blower.

	F	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 flexible 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 floor 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 noncombustible 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.

Ductwork preparation

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 specified CFM of air movement. The specified CFM varies from locale to locale. It is the responsibility of the owner and the installer to determine if additional requirements and/or standards apply to specific installations.

DO NOT USE FLEXIBLE DUCT; it creates back pressure/ air turbulence and reduces performance.

Always install a metal vent cover where the ductwork exits the house.

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.

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® recommends not exceeding 50 ft. (15 m) of 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 flex blower. Flex blower can be mounted to rear cabinet wall or to a platform / frame (not provided) on the base of the cabinet floor. (See flex 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 flame 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 flat countertop for a proper installation. Note that a minimum of 2-7/8” (73 mm) of flat 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).

Cut countertop opening

1.Lay out and cut the cooktop cut-out far enough FORWARD so downdraft will fit behind it.

2.Set cooktop in place and slide it as far forward as possible without exposing any gaps. Center and square it with edges of countertop.

COOKTOP

Template against back edge of cooktop.

3.Place the plastic template against the back flange of the cooktop. Center the template. Trace around template to mark the downdraft opening.

4.Remove cooktop from countertop.

5.Cut downdraft opening. Be careful not to chip edges of countertop.

Installation with electric and induction cooktops

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.
