Do you have a question about the Bosch PGP6B5B62Z and is the answer not in the manual?
This document provides comprehensive installation instructions for a gas hob, detailing the necessary steps for safe and correct setup, connection, and gas type conversion.
The manual begins with crucial safety information, emphasizing that all installation, connection, regulation, and gas type conversion work must be performed by an authorized professional in accordance with applicable regulations and local requirements. It highlights the importance of adequate kitchen ventilation, especially when the gas appliance is in operation, and strictly prohibits installation in boats or vehicles. The warranty is only valid when the appliance is used as intended. Before installation, it is essential to verify that local conditions, including gas type, pressure, power, and voltage, are compatible with the appliance's rating plate specifications. The power cord must be secured to the cabinet to prevent contact with hot parts of the oven or hob. Prior to any work on the appliance, both the power and gas supplies must be switched off. The appliance must be connected to the power supply with proper earthing, and no internal modifications should be made.
Before proceeding with installation, the manual specifies that the appliance is a Class 3 built-in appliance according to EN 30-1-1 standards. The unit in which the appliance is installed must be stable and securely fixed. Surrounding units, laminated panels, and adhesives must be made of non-flammable, heat-resistant materials. The appliance should not be installed above refrigerators, washing machines, or dishwashers. If installed above an oven, the oven must have forced ventilation, and the dimensions specified in the oven's installation instructions should be checked. If an oven is installed beneath the hob, the work surface thickness might differ from the dimensions provided in these instructions, requiring reference to the oven's installation guide. Similarly, if an exhaust air fan or extractor hood is installed, their respective installation instructions must be consulted, always maintaining the minimum vertical distance to the hob.
The preparation of the units involves creating a cut-out in the worktop with the required dimensions. For wooden work surfaces, the cut edges must be sealed with a special glue seal to protect against moisture. If no built-in oven is present underneath the hob, a non-flammable separator (e.g., metal or plywood) must be inserted at a distance of 10 mm from the hob to prevent access to its underside. The distance from the intermediate floor to the appliance's mains connection must also be at least 10 mm.
For positioning the appliance, it is crucial not to use silicone to bond the appliance to the worktop. First, the hob should be placed upside down on a flat, stable surface. The supplied adhesive seal must then be applied to the lower edge of the hob to prevent liquid penetration. The supplied brackets are screwed into their designated positions, allowing them to turn freely. The hob is then turned over and inserted into the recess, starting from the front. Finally, the brackets are turned and fully tightened, with their position depending on the worktop thickness.
To remove the appliance, it must first be disconnected from both electricity and gas supplies. The brackets are then unscrewed, and the removal process is reversed.
Connecting the gas supply requires adherence to country-specific guidelines. A gas leakage poses an explosion risk, so any connection must be checked for seals. The gas connection's shut-off valve must be accessible. It is essential to ensure that the gas type and pressure information on the appliance's rating plate matches the local connection conditions. The appliance should be connected to a fixed gas pipe or a flexible metal pipe. The flexible metal pipe must not come into contact with moving parts of the unit (e.g., a drawer) and must not be routed through obstructed spaces. The gas connection elbow on the appliance is G 1/2 and should not be moved or twisted. Spare parts for the gas connection can be obtained from technical customer service. When inserting the seal between the gas connection of the appliance and the gas supply, refer to the provided diagrams.
For electrical connection, the appliance is type Y. The connection cable must only be replaced by technical customer service, not the user, and the cable type and minimum cross-section must be respected. Hobs are supplied with a power cord, with or without a plug. Only appliances with a plug should be connected to a correctly installed socket with a protective earth conductor. If the plug is not accessible, an all-pole isolating safety switch with a minimum contact opening of 3 mm must be provided.
The appliance can be adapted to different gas types if allowed by country regulations and if the gas types are listed on the rating plate. The necessary parts for conversion are supplied with the appliance or can be obtained from customer service. A table indicates the correct combination for the relevant burner and gas type, categorizing burners as Economy, Standard-output, High-output, and Mini-wok multi-crown.
Adjusting the taps involves turning the rotary knobs to the minimum power position and pulling them out. Using a screwdriver, the flexible rubber holder is pushed down to access the bypass screw. If the bypass screw is inaccessible, the upper side of the appliance must be removed. The sealing ring should never be removed, as it prevents liquids and dirt from entering the appliance and impairing its function. When adjusting the bypass screws with a slotted-head screwdriver, refer to the table for guidance. For type A, bypass screws should be firmly tightened. For type B, bypass screws should be turned until the gas flow from the burners is correct.
Replacing the nozzles requires removing all pan supports, burner caps, and distributors. The nozzles are then replaced using the appropriate wrench and carefully tightened to ensure a proper seal, ensuring they do not detach during removal or fastening.
To remove the cover, pan supports, burner caps, distributors, and rotary knobs must be removed. The screws on the burners are undone, and the cover is carefully removed. Reinstalling the appliance involves reversing these steps.
After installation, it is crucial to check if the equipment is working correctly. Turning the rotary knob between the maximum and minimum power positions should not cause the burner to go out or result in backfire. If the gas flow from the burner is incorrect, the table should be consulted to verify the correct nozzle and bypass screw settings. The bypass screw should then be tightened or loosened until the gas flow from the burner is correct. Finally, a sticker indicating the new gas type must be attached near the rating plate to document the conversion.
