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.
•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 manuals. All other servicing should be done by a qualified technician. This may reduce the risk of personal injury and damage to the range.
•Never modify 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 LIFT 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.

Preparation
Installation
Final Steps
1. Install Ventilation
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 installed according to instructions furnished with the hood.
2. Prepare Cabinets
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 installed (See Figure 1).**
RequiredClearances***
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 MSG sheet metal, 0.015 inch stainless steel’ or 0.024 inch aluminum or copper.
From range walls to adjacent materials (See Figure 2)
No clearance is required from unit walls to adjacent 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-cleaning ovens; the cabinets may discolor or stain. This is most noticeable with laminated cabinets.
3. Prepare Electrical Outlet
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 will rest against wall properly.
5. Prepare Range

Figure 3: Prepare Electrical Outlet
Place range in front of cabinets where it is to be installed. Remove any packaging.
Tips:
Tape warming drawer or storage drawer shut to keep it from opening while installing the range.
During installation, place a portion of the box or a piece of cloth under the range to protect floors.
To make range lighter and easier to handle, remove door (see instructions in Use and Care manual).
** 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.

To prevent electrical shock, the grounding prong on the range cord should not be cut or removed under any circumstances. It must be plugged into a matching grounding type receptacle and connected to a correctly polarized 240Volt circuit. If there is any doubt as to whether the wall receptacle is properly grounded, have it checked by a qualified electrician.
GeneralInformation
Ranges are dual rated for use on either 120/240 VAC or 120/208 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 120/240 volt, 50 amperes minimum. The power cord set shall be marked “For Use with 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 is shipped 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 (More 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.)
Place strain relief in knockout below terminal block (See Figure 4). Feed range cord through hole and strain relief up to terminal block. Allow for slack in the cord between the strain relief and terminal block. Once cord length/ slack has been adjusted, attach strain relief per instructions included with strain relief.

TIP
The knockout panel (below the terminal block) can be removed from the range to install the strain relief: Remove panel from range, install strain relief in panel and reattach. DO NOT remove entire range back panel.
WARNING
Risk of Electric Shock or Fire. Frame grounded to neutral through a ground strap. Grounding through the neutral conductor is prohibited for new branch-circuit installations (1996 NEC), mobile homes, and recreational vehicles, or in an area where local codes prohibit grounding through the neutral conductor.
For installations where grounding through the neutral conductor is prohibited, (a) disconnect the link from the neutral, (b) use grounding terminal or lead to ground unit, (c) connect neutral terminal to lead branch circuit neutral in usual manner (when the appliance is to be connected by means of a cord kit, use 4-conductor cord for this purpose).
Use only cord kits rated 125/250 volts (minimum), 50 amperes and labeled “For Use with Ranges”. Strain relief provided with cord must be installed per instructions included with cord.
