This document provides operating instructions for the Bosch Condens 5000W series of wall-mounted gas condensing boilers, specifically models ZBR 70-3 and ZBR 100-3. It covers essential information for users to safely and efficiently operate and maintain their heating system.
The Bosch Condens 5000W is a wall-mounted gas condensing boiler designed for heating boiler water and domestic hot water (DHW). It utilizes gas combustion to generate heat, and its condensing technology allows for higher efficiency by recovering heat from the flue gases. The boiler is equipped with a control panel that serves as the primary interface for users to monitor and adjust its operation. It can operate in various modes, including central heating and DHW production, which can be controlled independently. The system incorporates anti-freeze protection to prevent damage during cold seasons by ensuring continuous water flow through the heating system. In case of operational issues, the boiler is designed to display fault codes, providing users with information to diagnose and address problems.
The boiler's operation is managed through a user-friendly control panel, which includes an ON/OFF switch, a "Reset" key, an "Emissions test" key, a "Help" key, a "Menu" key, "Down" and "Up" arrow keys, and a diagnostic plug.
Commissioning: Before operation, users need to ensure the gas tap and service valves are open. The boiler is switched on using the ON/OFF switch. Water pressure can be checked directly on the display, and the heating system should be topped up if the pressure is too low (typically between 1.0 and 2.0 bar). The maximum boiler temperature can be set in the setup menu, allowing users to tailor the heating output to their specific needs (e.g., 40 °C for underfloor heating, 75-85 °C for radiators, 85-90 °C for convectors).
Operating the Appliance: The control panel allows access to two main menus: the information menu and the setup menu.
Anti-Freeze Protection: To prevent freezing, users should ensure all radiator valves are open and set the pump overrun time to 24 hours in the setup menu. If the boiler is switched off, specific shutdown procedures for frost risk should be followed, which may involve draining the entire heating system.
Key Lock: The setup menu can be locked to prevent unauthorized changes to settings. This feature is activated and deactivated by simultaneously pressing the "Down" and "Up" arrow keys for 5 seconds. While locked, the information menu remains accessible.
Shutdown: For a standard shutdown, the ON/OFF switch should be set to "0," and the gas isolator under the boiler should be closed. In situations with a risk of frost, additional steps, such as setting the pump overrun time or draining the heating system, are required.
Regular inspection and maintenance are crucial for the safe and efficient operation of the Bosch Condens 5000W boiler.
Inspection and Maintenance: It is recommended that the heating system be inspected and serviced annually by a certified installer. This includes cleaning the heat source at least every two years. Users are encouraged to enter into an annual inspection and maintenance contract with an approved contractor.
Refilling the Heating System: The manual advises users to consult their installer for instructions on refilling the heating system, as the process may vary depending on water quality.
Cleaning the Casing: The boiler casing should only be cleaned with a damp cloth and, if necessary, a mild detergent.
Display Rendition and Fault Codes: The boiler provides detailed information through its display, including operating codes and fault codes.
Safety Instructions: The manual emphasizes several safety instructions, including precautions for gas leaks, flue gas poisoning, and carbon monoxide. It stresses the importance of having all work carried out by an approved contractor, never modifying any parts of the heating system, and ensuring adequate ventilation for open flue operation. Environmental protection and proper disposal of the appliance and its packaging are also highlighted.
