The appliance must be installed in closed heating systems, that have been installed in accordance with current regulations and with the current state of the art. -
Page 10: Chimney Flue
chimney flue the sizing, installation and connection of the chimney flue to the boiler must be carried out by an authorised company of master chimney sweepers according to european, national and local regulations. The flue must develop a sufficient draught to convey and transport combustion smoke outdoors at all operating speeds. It is important to have an adequately sized self-sufficient flue for the boiler to operate correctly. -

- have the system repaired. The system must be commissioned by the installing company (specialising in the construction of heating systems) or by an authorised la nordica spa service centre. This must be documented in a commissioning report. It is necessary to check that all system components have been installed correctly and that all control and safety devices are working properly and are correctly set. -
Page 12: Permitted Fuels
If the system is not commissioned by legally qualified and authorised personnel, the warranty will be void. The prerequisites for trouble-free operation are: - Periodic cleaning of the boiler - good fuel quality; - constant flue draught; - a sufficient supply of fresh air of at least 4 m³/h for 1 kW in the installation room; - built-in and regulated draught regulator. -

anti-conDensation mixinG valve for 60°c recirculation circuit (can be supplied as an optional accessory). The anti-condensation mixing valve is used in solid combustion heating devices and boilers since it prevents the return of cold water into the heat exchanger. sections 1 and 3 are always open and, together with the pump installed on the return (r), they guarantee circulation of water inside the heat exchanger of the biomass boiler (down-fired boiler). -

first start-up The first IgnITIon requires a special approach. It differs from normal operation, as described below, because the inside of the boiler and the refractory panels are still free of ash residue. all air intakes inside the combustion chamber (except for the nozzle stone) must be clogged over time to ensure clean and efficient operation. To do this, proceed as follows: line upper... -
Page 31: Heating (Normal Operation)
heatinG (normal operation) before heating with wood, it is necessary to consider the storage tank temperature to load the boiler with the correct amount of fuel. make sure that there is sufficient thermal capacity in the storage tank! Please pay attention to the heat demand of your system in relation to the external temperatures, especially in transition periods, to avoid overheating the system. - Page 32 close the upper and lower doors of the boiler. Place some paper or cardboard in front of the logs to help them light. start the iGnition process from the dIsPlay The IgnITIon process must be activated from the control display, only afTer The boIler has been loaded. 25°C 20 °C Temp.

Page 34: Adding Fuel
information on the safety Devices: at a boiler temperature of 85°c, the boiler switches to overheating mode or to modulation mode. This is an attempt to “slow down” combustion, in order to prevent a further rise in temperature, without stopping combustion. When the boiler temperature reaches 90°c, the smoke fan is deactivated in order to stop the combustion air and thus stifle combustion. -
Page 35: Control Display
