If you smell flue gas, immediately shut off the boiler. Leaking or blocked flue systems can pose life-threatening risks. The boiler should not be operated simultaneously with appliances that extract air to the outside. This can cause dangerous poisoning. Ensure adequate ventilation and combustion air supply. Keep the installation area free from the risk of frost, and when installing in wet rooms, ensure that electrical equipment is correctly installed as per VDE 0100. Always follow the safety instructions in the manual to ensure safe boiler operation.

Installation Guidelines for the Vitodens 050-W

The installation of the Viessmann Vitodens 050-W must be carried out by qualified professionals, adhering to the manufacturer’s guidelines. The installation area should be free from frost. The unit is suitable for wet rooms with appropriate electrical safety measures. Ensure a 700 mm clearance in front of the boiler for maintenance purposes. Side clearances are not needed. Use the provided installation template to mark rawl plug holes. When mounting in a cupboard, ensure it is specifically designed for this purpose. Securely mount the boiler onto the wall bracket. Follow all water and gas connection instructions carefully, mounting fittings with gaskets. Perform a gas tightness test using approved agents and devices. Purge the gas line, noting that excessive test pressure can damage the boiler. Connect the flue system correctly and ensure it functions properly. Do not close off any combustion air supply openings. The electrical connections must be made by a qualified electrician. Connect to the equipotential bonding of the building to prevent electrical hazards. Correctly route connecting cables to avoid damage.

Electrical Connection Procedures

The electrical connections for the Viessmann Vitodens 050-W must be performed by a certified electrician, strictly following the guidelines provided in the user manual and adhering to local regulations. Ensure that the appliance is disconnected from the power supply before commencing any electrical work. The terminals are located on the underside of the appliance. When connecting accessories like outside temperature sensors or room temperature controllers, refer to the specific installation instructions provided with each accessory. The outside temperature sensor should be installed on a north or north-westerly wall, 2 to 2.5 meters above ground level. In multi-story buildings, mount it in the upper half of the second floor. Connect the outside temperature sensor to terminals 3 and 4. It is critical to connect the appliance and pipework to the equipotential bonding of the building to prevent electrical shock. Ensure that connecting cables are routed properly to prevent damage. Any faulty components must be replaced only with original Viessmann spare parts. Failure to adhere to these procedures can result in severe electrical hazards and damage to the appliance.

Commissioning and Initial Startup

Commissioning of the Viessmann Vitodens 050-W is a critical process that must be conducted by a qualified technician. The initial step involves filling the heating system with water, ensuring it meets the recommended hardness levels. Water with a hardness above 300 ppm should be softened to prevent deposits and corrosion. Open all shut-off valves, fill, and vent the heating system until the system pressure reaches 0.8 to 1.2 bar. The system can be filled using a separate filling point if necessary. After filling, the gas supply needs to be checked for proper connection and tightness. A pressure test should be carried out using suitable leak detection agents to confirm there are no leaks. Next, the gas line must be purged, and the boiler’s supply pressure needs to be checked against the set value of 20 mbar for natural gas. Start the boiler and verify its functionality. If converting to LPG, the procedure must be followed carefully with specific adjustments. Always ensure the flue system is functioning correctly. The burner output might need adjustment depending on the flue system.

Operation and Control Settings

The Vitodens 050-W is designed for ease of operation, featuring an automatic Lambda Pro combustion controller. The boiler operates with a constant boiler water temperature. Users can monitor and adjust settings via the integrated control unit. For enhanced control, optional accessories like the Vitotrol 100 room temperature controller or an outside temperature sensor can be connected. When using a room temperature controller, ensure it’s installed according to the provided instructions. The outside temperature sensor should be installed on a north or north-westerly wall, typically 2 to 2.5 meters above ground level. Ensure the system is properly connected to the equipotential bonding of the building for safety. The appliance has various operating modes, and the user manual provides clear instructions on how to navigate the menu. The mode button allows access to service settings, which should only be adjusted by qualified personnel. Understanding and using these controls will help in optimizing the boiler’s performance and energy efficiency. Always refer to the manual for detailed guidance on adjustments.
