Important information for system operator 1.1 Safety precautions The boiler and related accessories are state of the art and meet all applicable safety regulations. Your boiler and all accessories operate using 230 V AC electric current. Improper installation or repair can pose the danger of life-threatening electric shock. Installation may be performed only by appropriately qualified technicians. Caution symbols Please take careful note of the following symbols in this Operating Manual.
Important information for system operators 1.3 Start-up and maintenance Have Baxi Customer Service or one of our customer service PARTNERS put your new boiler into service. In this way, all functions of the new unit will be thoroughly checked; you will also benefit from the detailed information provided by the system installer. Installation by a qualified technician as well as the maintenance required by the guarantee limitations will guarantee the optimal use and service life of your boiler system.
Important information for system operators 1.6 Filling the pellet store The pellet flue-connected stove must be switched off correctly at least 15 minutes before the store is filled – Fig. 2. Press the ON/OFF button. Never switch off using the emergency OFF switch! Pressing one of the six buttons firstly switches just the lighting and display on. The boiler is only switched off when the button is pressed for the 2nd time.
Important information for system operators 1.7 Sources of danger 1.7.1 Fire protection The entire system must comply with technical fire protection requirements in accordance with the applicable regulations, standards and guidelines. All flammable materials in the close vicinity of the pellet central heating boiler for living areas must be protected against the effects of heat, in particular in the area of the front window. Do not drape clothing or other items over the BAXI Bioflo for drying them.
Operation 2.1 Functional description, function elements and operating controls The BAXI Bioflo automatically fires when the control system signals a heating requirement. Following „purging“ (safety function), ignition starts and the pellet metering auger switches on. The burner pot is automatically filled with pellets.
Operation 2.1.4 Heat shield (accessory FIRE 023) Heat radiated from the front window can lead to unwanted heating of the room where the unit has been set up when domestic hot water is being heated during the summer. If you do not want the room to be heated, you can significantly reduce the amount of heat radiated using the patented heat shield (accessory Fire 023). The air-to-water ratio without a heat shield is approx. 15 : 85 % and with a raised heat shield approx. 9 : 91 %.
Operation 2.2 Check before initial start-up a) System pressure (heating water pressure): The system must be filled and vented. With the system cold, pressure should be at least 1.0 bar (maximum 1.8 bar) – Fig. 6 If you have any questions, your installer will gladly answer them. Pressure gauge (system pressure) Filling and evacuation cock Fig. 6 Filling the system b) Ventilation: If you are operating the device with room air, please make sure the room where it is installed is well ventilated.
Operation 2.4 Info panel The Info panel is located at the top under the glass cover. Press the locking button at the front and fold the glass cover open, the Info panel pops up automatically – Figs. 8, 9. It consists of a large full text display, an ON/OFF button with an LED signal lamp indicating Operation (green) or Malfunction (red), a button for manual operation / flue cleaning function as well as four individual menu buttons. The function of each menu button is displayed on the Menu line. Fig.

Care, cleaning and maintenance 3.1 Care of the front window, cladding and keyboard foil The front window is equipped with a special back ventilation. This ensures that the window remains clean for a relatively long time. Nevertheless, light deposits formed by ash constituents will form on the inside of the glass window (inside window). This causes the viewing window to be obscured. This obscuring has no effect whatsoever on the quality of combustion.
Care, cleaning and maintenance Care, cleaning and ash removal intervals BAXI Bioflo Depending on pellet consumption Approx. every 37 kg Add pellets to reserve supply container (~ 20 operating hours) Empty the ash pan(s) Depending on pellet consumption Approx.
Care, cleaning and maintenance 3.4 Heating surfaces Optimum efficiency is achieved when the heating surfaces are cleaned as often as possible using the cleaning lever. However, the cleaning lever should be connected on the right side and moved backwards and forwards several time at the latest before the ash pan is removed or the ash removed from the heating surfaces –– Fig. 78. Fig. 78 3.
Care, cleaning and maintenance 3.6 Combustion chamber The BAXI Bioflo is equipped with a cleaning interval display. The cleaning request for the combustion chamber and burner pot is displayed on the info panel after 500 operating hours, and must be reset after cleaning has finished – see section 2.8.1.6. „Boiler cleaning – Resetting the cleaning request“. Do not open the combustion chamber door during operation. Always switch the boiler off first with the ON/OFF button (Fig.
Care, cleaning and maintenance 3.6.2 Burner pot Do not open the combustion chamber door during operation. Always switch the boiler off first with the ON/OFF button and wait until burnout mode has finished. It is essential to let the boiler cool down before cleaning.
Care, cleaning and maintenance 3.7 BAXI Bioflo reserve supply container It is necessary to clean the reserve supply container if too much dust has collected on the sides or at the opening above the auger, or there are foreign bodies in the reserve supply container. In order to be able to check this, there must not be any pellets in the reserve supply container.
Care, cleaning and maintenance 3.8 Top heating surfaces and linkage These parts are automatically checked and cleaned as part of the annual maintenance by heatteam, the service division of BAXI Group Always switch the boiler off first with the ON/OFF button (Fig. 88) and wait until burnout mode has finished.
