  • Page 11 2-INSTALLATION INSTRUCT CONNECTION OF THE SMOKE EXHAUST DUCT When making the hole for the passage of the smoke discharge pipe, one must take into account the possible presence of flammable materials. If the hole must be made through a wooden wall or thermolabile material, the INSTALLER MUST first of all use the appropriate wall fitting (minimum diameter 13 cm) and suitably insulate the pipe of the product that passes through it using adequate insulating materials (1.3 - 5 cm thick with minimum thermal conductivity 0.07 W/m°K).
  • Page 12 2-INSTALLATION INSTRUCT Always use pipes and fittings with appropriate seals that guarantee tightness.

  • Page 13 2-INSTALLATION INSTRUCT CONNECTION TO THE EXTERNAL AIR INLET It is essential for the room where the product is installed to be adequately ventilated in order to guarantee sufficient air for proper combustion in the appliance. This is possible by means of suitable ventilation openings in the room itself or in an interconnected room through a permanent opening between the rooms (room ventilation is excluded in the case of installation with Oyster technology, where combustion air is ducted directly from outside) For this purpose, drill a hole on the outer wall close to the product with a minimum section of 80 cm²...

  • Page 15 2-INSTALLATION INSTRUCT OPERATING PROBLEMS RELATED TO DRAUGHT DEFECTS IN THE CHIMNEY Among all the weather and geographical conditions that affect 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 difference in temperature between inside and outside the chimney, there is another type of depression (or overpressure): dynamic pressure caused by the wind.

    5-PLUMBING CONNECTION PLUMBING CONNECTION IMPORTANT: The connections depend on the type of hydraulic kit installed and on the type of System Configuration. IMPORTANT! If installation of the product involves interaction with another, pre-existing system complete with heating equipment (gas boiler, methane boiler, diesel boiler, etc.), contact qualified personnel, who subsequently will be responsible for conformity of the system in compliance with the applicable law in force.
  • Page 22 5-PLUMBING CONNECTION SYSTEM FILLING Filling must be carried out slowly so that air bubbles can get out via the purposely placed outlets on the heating system. In closed circuit heating systems the loading pressure of the system when cold and the expansion tank preloading pressure must be tha same. •...
  • Page 23 5-PLUMBING CONNECTION To fill the system, the hydraulic kit (optional) is fitted with a tap, with a check valve, to load the heating system manually. During this operation, any air in the system is released via the air valve located in the upper part of the boiler. To ensure the valve vents, it is advisable to loosen the side cap (see figure) The filling pressure of the system WHEN COLD must be 1 bar.

  • Page 25: 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 26 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 light creaking noises may be heard.
  • Page 27 7-INITIAL START-UP LOADING THE PELLETS Pellets loading can be either manual or automatic. When empty the hopper can contain 100 litres i.e. roughly 70 kg of pellets. Manual Loading: • Open the upper door of the boiler directly and pour in the pellets. Automatic Loading (to be combined with the remote 100/200 or 400 kg hopper - optional - see accessories): •...
