  • Page 14 2-INSTALLATION INSTRUCTIONS OPERATING PROBLEMS RELATED TO DRAUGHT DEFECTS IN THE CHIMNEY Among all the weather and geographical conditions that a ect chimney operation (rain, fog, snow, altitude a.s.l., exposure to sunlight, orientation to the cardinal points, etc.), the wind is certainly the most determinant. In fact, besides the thermal depression caused by the di erence in temperature between inside and outside the chimney, there is another type of depression (or overpressure): dynamic pressure caused by the wind.

  • Page 26 To allow the valve to vent, it is recommended to loosen the grey cap by one turn and leave the red cap locked (see gure). The lling pressure of the system WHEN COLD must be 1 bar. If during operation the system pressure drops (due to evaporation of gases dissolved in the water) to values lower than the minimum ones indicated above, the user must use the lling tap to bring the pressure back up to its initial pressure.
  • Page 27 5-PLUMBING CONNECTION WATER CHARACTERISTICS The characteristics of the water used to ll the system are very important to prevent the build-up of mineral salts and the formation of incrustations along the pipes, in the boiler and in the heat exchangers. Therefore, please ASK YOUR PLUMBER FOR HIS ADVICE CONCERNING: Hardness of water circulating in the system, to prevent problems of incrustation and limescale, especially in the domestic water heat exchanger.

  • Page 29: Initial Start Up

    7 - INITIAL START-UP BEFORE START-UP GENERAL PRECAUTIONS Remove all components that could burn from the brazier and glass (manual, various adhesive labels and any polystyrene). Check that the brazier is positioned correctly and rests properly on the base. After a long period of inactivity, remove any pellets left in the hopper (using a vacuum cleaner with a long pipe ), as they could have absorbed moisture, thereby altering their original characteristics and no longer being suitable for combustion.
  • Page 30 7 - INITIAL START-UP Do not stand close to the product and air the room. The smoke and smell of paint will disappear after about an hour of operation, however, remember they are not harmful in any case. The boiler will be subject to expansion and contraction during the start-up and cooling phases, therefore slight creaking noises may be heard.
  • Page 31 7 - INITIAL START-UP LOADING THE PELLETS Fuel is loaded from the upper part of the stove by opening the door. Pour the pellets into the hopper. To ease the procedure carry out the operation in two steps: Pour half of the contents into the hopper and wait for the fuel to settle on the bottom. Then complete the operation by pouring in the rest.

  • Page 42: Operation

    10-OPERATION OPERATING MODE The operating mode for hydro boilers is AUTOMATIC only (manual mode is not envisioned). Flame modulation is managed according to the “System con guration” of the room probe placed on the rear of the appliance (see drawing), by the external thermostat, by the boiler water temperature or by the NTC probes.
  • Page 43 10-OPERATION EXTERNAL THERMOSTAT CONNECTION (e) EXTERNAL THERMOSTAT (not included with the boiler, to be provided by the user) The temperature of the boiler can also be controlled by an external room thermostat. It is located in a central position of the room where the boiler is installed.
  • Page 44 10-OPERATION START-UP Press key 1 (esc) to begin start-up, the control panel displays ON with a ashing ame. When the ame stops ashing the boiler has reached the “power output” operating mode. The room temperature set by default is 20°C, if one wishes to change it act as instructed in the adjustments menu; act likewise to set the heating water temperature and the room fan speed (if envisaged).
  • Page 45 10-OPERATION PROGRAMMED MODE (TIMER) - Main menu Setting the current day and time is essential for the proper operation of the timer. There are six TIMER programmes, for each one the user can decide the start-up and shutdown time as well as the day of the week in which it is active.
  • Page 46 10-OPERATION NOTES FOR TIMER OPERATION Start-up with the timer always takes place with the last temperature and ventilation settings (or with default 20°C and V3 settings in the event they have never been changed). Start-up time ranges from 00:00 a 23:50 If the shutdown time is not already memorised, it proposes a start-up time in + 10 minutes.
  • Page 47 10-OPERATION AUXILIARY BOILER (see section 8i) One must install an additional module (optional) to enable start-up of an auxiliary boiler in the event the stove is switched o or in alarm conditions. By default this function is deactivated, if needed activate it to access the settings menu. PELLETS RECIPE (see section 8j) This function is for adapting the stove to the pellets that are being used.
  • Page 48 10-OPERATION SEASON FUNCTION (see section 8p) In con gurations 2 and 3, by enabling the “summer” function, the deviation of the 3-way valve to the heating system is inhibited in order to prevent the radiators from heating up, therefore the ow is always directed towards the domestic hot water (DHW) - if envisaged. By activating the “summer”...
