Viessmann Vitola-Biferral-E Series BE Oil Burner Operating Instructions

The Viessmann Vitola-Biferral-E Series BE features dual-fuel capability, a biferral heat exchanger, and a modulating burner for optimized efficiency and performance.
To perform a basic maintenance check, inspect the burner, clean the heat exchanger, check the oil filter and nozzle, and ensure proper ventilation and flue gas evacuation.
Check the oil supply, reset the burner, inspect the ignition electrodes, and verify that the control settings are correct. If the issue persists, contact a professional technician.
Regular maintenance, using a programmable thermostat, insulating heating pipes, and ensuring all system components are clean and functioning properly can improve energy efficiency.

The boiler should be serviced annually by a qualified technician to ensure optimal performance and safety.
The boiler is compatible with low-sulfur No. 2 heating oil and can be adapted to use natural gas with appropriate modifications.
Adjust the water temperature using the control panel settings. Consult the user manual for detailed instructions based on your specific control model.
The boiler includes safety features such as a high limit switch, flame sensor, pressure relief valve, and automatic shutdown in case of malfunction.
To bleed air, locate the bleed valve on the radiator or boiler, open the valve slowly with a bleed key until water starts to flow, then close the valve. Ensure the system pressure is adequate after bleeding.
