Bosch Gas Hob Installation Instructions

Safe Installation

Follow these safety instructions when installing the appliance.

• Read this instruction manual carefully.
• The images shown in these instructions are for guidance only.
• The appliance can only be used safely if it is correctly installed according to the safety instructions. The installer is responsible for ensuring that the appliance works perfectly at its installation location.
• Once you have established the connections, carry out a test for leaks.

⚠️ WARNING – Risk of explosion! Escaping gas may cause an explosion.

All installation, connection, regulating, and conversion work to a different gas type must be carried out by an authorised professional, taking into account applicable regulations and legal requirements, as well as local electricity and gas supplier regulations. Special attention must be paid to ventilation provisions and guidelines. For conversion work to a different gas type, contact the after-sales service.

⚠️ WARNING – Danger: Magnetism! Caution: Magnetic field.

Attention for persons with pacemakers: Permanent magnets are integrated in the control element bases and control elements. Magnets may affect electronic implants, e.g. heart pacemakers or insulin pumps.

• Persons with electronic implants must stand at least 10 cm away from the magnetic control element bases and control elements.
• Never carry the control element base and control elements on your body.

• Ensure that the kitchen is sufficiently ventilated, particularly when operating the gas cooking appliance.
• Do not connect the appliance to an exhaust gas system for combustion products.
• Never install the appliance in boats or vehicles.
• The warranty applies only when using the appliance as intended.
• Before installing, check that local supplier conditions are compatible with appliance settings on the rating plate (gas type, pressure, power, voltage).
• Secure the power cord to the cabinet to prevent it from touching hot parts of the oven or hob.
• Before any work, switch off the power supply and the gas supply.
• Connect the appliance to the power supply using the earth connection.
• Do not make any changes inside the appliance. Contact technical customer service if required.

Before Installing

• This appliance is a class 3 appliance in accordance with the EN 30-1-1 standard for gas appliances: Built-in appliance.
• The unit in which the appliance is installed must be stable and secured appropriately.
• Units in the vicinity, laminated panels, and adhesive must be made of non-flammable, heat-resistant materials.
• Do not install this appliance above refrigerators, washing machines, dishwashers, or similar.
• The appliance must only be installed on an oven with forced ventilation. Check oven installation instructions for dimensions.
• If installing an oven underneath, work surface thickness may differ. Refer to oven installation instructions.
• For exhaust air fans or extractor hoods, refer to their installation instructions. Always observe the minimum vertical distance to the hob. (See Figure 1)

Preparing the Units

• Make a cut-out in the worktop with the required dimensions. (See Figures 2, 3)
• Any panel closer to the built-in niche than specified clearance must be non-combustible. Maintain at least 5 mm distance between the panel and the appliance. Maximum panel dimensions: 30 mm thickness x 70 mm height.
• Seal cut surfaces of wooden work surfaces with a special glue seal to protect from moisture.
• If no built-in oven is underneath, insert a non-flammable separator (e.g., metal or plywood) at least 10 mm from the hob. This prevents access to the underside. The distance from the intermediate floor to the mains connection must be at least 10 mm. (See Figures 1, A)

Positioning the Appliance

Note: Do not use silicone to bond the appliance to the worktop.

1. Position the hob with the upper side facing down on a flat, stable surface.
2. Apply the supplied adhesive seal to the lower edge of the hob. The seal prevents liquid penetration. (See Figure 6 ✔️)
3. Screw the supplied brackets into the specified position so they can turn freely. (See Figure 7)
4. Turn the hob around and insert it into the recess, front first. (See Figure 8)
5. Turn the brackets and tighten them fully. (See Figure 9) The bracket position depends on worktop thickness.

Removing the Appliance

1. Disconnect the appliance from electricity and gas connections.
2. Unscrew the brackets and proceed in reverse order.

Connecting the Gas

Observe country-specific guidelines.

⚠️ CAUTION – Risk of explosion! A gas leakage may cause an explosion.

If any connection is handled, check the seal.

• Arrange the gas connection so the shut-off valve is accessible.
• Ensure the rating plate information (gas type, pressure) complies with local connection conditions.
• Connect to a fixed gas pipe or a flexible metal pipe.
• The flexible metal pipe must not contact moving parts (e.g., in a drawer) and must not be routed through obstructed spaces.
• Gas connection elbow on appliance: R 1/2.
• Do not move or twist the gas connection elbow.

Connection to Gas Cylinder or Liquid Gas Tank

If the flame is large or unstable, check the gas cylinder/tank regulator ⛽. Note: An overpressure safety device can be installed to limit or cut off gas supply if the regulator fails.

Spare Parts for Gas Connection

Country regulations permitting, obtain gas connection parts from technical customer service. (See Figure 10)

Gas Connection R 1/2

(See Figure 11)

Gas Connection G 1/2

1. Replace the gas connection elbow on the appliance with the G 1/2 elbow supplied in the accessory bag. (See Figure 12)
2. Insert the seal between the appliance gas connection and the gas supply. (See Figure 13)

Electrical Connection

• This appliance is type Y: The connection cable must only be replaced by technical customer service. Cable type and minimum cross-section must be respected.
• Hobs are supplied with a power cord with or without a plug ?.
• The power cable must only be replaced with a cable from the original manufacturer, available from after-sales service.
• Do not use extension cables or multiple socket strips.
• Only connect appliances fitted with a plug to a correctly installed socket with a protective earth conductor.
• Connect to a fixed installation and set up appropriate isolating switches in accordance with installation regulations. (See Figure 14 ⚡)
• Wire colors: BN: Brown, BU: Blue, GN/YE: Green and yellow.

Converting the Gas Type

If country regulations allow, this appliance can be adapted to other gas types listed on the rating plate. Find the right parts in the supplied bag or obtain them from customer service. Table (See Figure 19) shows the correct combination for burner and gas type.

Burner Types:

• C Economy burner
• D Standard-output burner
• E High-output burner
• F Mini-wok multi-crown burner
• G Wok multi-crown burner

Adjusting the Taps

1. Set control elements to minimum power level and pull them out. Remove the plinth for control elements.
2. To access the bypass screw, use a screwdriver tip ? to push down on the flexible rubber holder. (See Figure 15) Never remove the sealing ring. Sealing rings prevent liquids and dirt from impairing function.
3. When adjusting bypass screws (M), refer to the table (See Figure 19).
• A: Firmly tighten the bypass screws.
• B: Bypass screws must be flush with the fitting. (See Figure 16)

Replacing the Nozzles

1. Remove all pan supports, burner caps, and distributors.
2. Replace nozzles using the appropriate wrench ? and tighten carefully to guarantee the seal. (See Figures 17, 18) Ensure the nozzle does not become detached during removal or fastening.

Reinstalling the Appliance

Install the appliance components in reverse order.

Checking if Equipment is Working

1. Check that turning the rotary knob between maximum and minimum power does not cause the burner to go out or result in backfire.
2. If gas flow is incorrect, check the nozzle and bypass screw position in the table (See Figure 19).

Documenting the Gas Type Conversion

Attach the sticker showing the new gas type near to the rating plate.
