_ WARNING

Before installing, turn power OFF at the service
panel. Lock service panel to prevent power

from being turned ON accidentally.

Stepping, leaning or sitting on the doors or
drawers of this range can result in serious
injuries and also cause damage to the range.
Do not allow children to climb or play around
the range. The weight of a child on an open
door may cause the range to tip, resulting in
serious burns or other injury.

Do not store items of interest to children in the
cabinets above a range or on the backguard of a

range. Children climbing on the range to reach

,_ items could be seriously injured. J

Remove all tape and packaging before using

the range. Destroy the packaging after unpacking
the range. Never allow children to play with

packaging material.
Be sure your appliance is properly installed

and grounded by a qualified technician in
accordance with the National Electrical Code ANSI!

NFPA No. 7 latest edition and local electrical code
requirements.

Important: Local codes vary. Installation, electrical
connections and grounding must comply with all
applicable codes.

:Install only per installation instructions
provided in the literature package for this

range.

• Ask your dealer to recommend a qualified
technician and an authorized repair service.

• Know how to disconnect the power to the

range at the circuit breaker or fuse box in case of
an emergency.

. Do not repair or replace any part of the

appliance unless specifically recommended
in the _anuats. All other servicing should be
done by a qualified technician. This may reduce

the risk of personal injury and damage to the

range.

• Never _odify or alter the construction of a

range by removing leveling legs, panels, wire
covers, anti=tip brackets/screws, or any other part
of the product.

DO NOT L%FT RANGE BY DOOR HANDLE.

Remove the door for easier handling and
installation. See 'Removing Oven Door' in the
Maintenance section of the Use and Care Manual.

CAUTION

Do not use the warming drawer(if equipped) or

oven for storage.
Unit is heavy and requires at least two people or

proper equipment to move.

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

Steps 1 through 5." Preparation

f

Bosch strongly recommends the installation of a
ventilation hood above this range, For most kitchens a
certified hood rating of not less than 300 CFM is
recommended, The range hood must be instal(ed
according to instructions furnished with the hood.

2. Prepare Cab(nets

This unit is designed for installation near adjacent walls

and projecting surfaces constructed of combustible
materials,

Allow a minimum of 30 inches between cabinets where

range is to be instaUed (See Figure 1).**
Required Clearances *_

From cooktop to materials above (See Figure 2)

There must be a minimum clearance of 30 inches

between the top of the cooking surface and the bottom
of an unprotected wood or metal cabinet.

24 inches is acceptable when the bottom of the wood or
metal cabinet is protected by (a) not less than 1/4" of

flame retardant material which must be covered with
(b) not less than No. 28 MS(3sheet metal, 0.0!5 inch
stainless steel' or 0.024 inch aluminum or copper.

vertical combustible walls on rear, right or left.
Clearance from range top to adjacent vertical walls

must be at least 4':
NOTE: Some cabinet finishes cannot survive the

temperatures allowed by U.L, particularly self<leaning

ovens; the cabinets may discolor or stain. This is most
noticeable with laminated cabinets.

3o Prepare Electrical Outlet

Figure 2: Required Clearances

The electrical outlet must be located in the shaded

space in Figure 3.

4. Prepare Walls and Floor

Seal any holes in the walls or floor. Remove any
obstructions (extra electrical or gas connections, etc.) so

that range wiil rest against wall properly.

Prepare Range

F{igure 3: Prepare Electrical Oudet

Place range in front of cabinets where it is to be
installed. Remove any packaging.

** 12 mm clearance from range sidewall to cabinet required in Canada.
***Instructions were determined using Standard American cabinets. Standard base cabinets measure 36" high x 24" deep . Cabinets
over the cooking surface and cabinets adjacent to those over the cooking surface measure 13 inches deep from backwall. If
nonstandard cabinets are used, care should be taken to alter dimensions accordingly.

Step 6: Preparation (cont'd)

6o Prepare Emectrical Connection

Verify that wiring to house is adequate.

Contact your local utility company to verify that the present
electric service to your home is adequate. In some
instances, the sizeof the wiring to the house and service

switch must be increased to handle the electrical load
demanded by the range.

Verify that Wiring inside house is adequate.

Most wiring codes require a separate circuit with separate
disconnect switch and fuses either in the main entrance

panel or in a separate switch and fuse box.
Most local building regulations and codes require that

electrical wiring be done by licensed electricians. Besure

to install your range according to the electric codes in place

in your region.

_ILTo prevent electri_l shock, grounding

the

prong on the range cord shouJd not be cut or
removed under any circumstances. It must be
plugged into a matching grounding type receptacle and
connected to a correctly polarized 240=Volt circuit. If there

grounded, have it checked by a qualified electrician.

General Information
Ranges are dual rated for use on either :[20/240 VAC or

:[20/208 VAC. See chart at right for power ratings and

circuit breaker sizes based upon the supply voltage for
each model.

Bosch recommends that the range be installed with a UL
approved power cord set (not supplied). The electrical
rating of the power cord set must be :[20/240 volt, 50
amperes minimum. The power cord set shall be marked

strain relief.

"For Usewith Ranges." Always use a new power cord.
Alternatively, the range can also be hard wired using

the aluminum terminal lugs included in the literature

pack. If using this connection, flexible conduit must also
be used (not supplied).

Bosch recommends a 50 AMP, 60 Hz, 4 wire circuit;
However, the NEC (National Electric Code) allows for
some ranges to be installed on a 40 AMP circuit. Refer

to your local electric code requirements in order to

determine the required amperage. Always choose a
range power cord set that is rated for the circuit.

In compliance with the NEC,a separate circuit is also
recommended.

Note; In Canada, the range isshipped from the factory
with the range cord already installed. Proceed to"Steps 8

and 9: Installation =Final Steps"
For installations other than those in Canada, connect the

range cord (or wire conductors) at the terminal block
(Hore detailed instructions are found on pages 4 and

5). Access the terminal block by removing the cover in

the lower right hand corner of the range back panel

(See Figure 4). Install the strain relief and the proper
connector through the knockout(s) provided. The
electrical supply, including flexible conduit or power
cord, should be restricted to the shaded areas in Figure
3 (previous page.)
