    2 - INSTALLATION INSTRUCTIONS RULES FOR INSTALLATION The product in question is a stove that uses wood pellets. Below is a list of the European regulations regarding the installation of the product: EN 12828 Heating systems design. IEC 64-8 Electrical systems with rated voltage not exceeding 1000 V AC and 1500 V DC. EN 1443 General chimney regulation EN 1856-1 metal smoke ducts EN 1856-2 metal smoke extraction channels...
  • Page 11 2 - INSTALLATION INSTRUCTIONS The instructions in this chapter refer explicitly to the Italian installation regulation UNI 10683. In any case, always observe the domestic regulations in force. PELLETS Wood pellets are manufactured by hot-extruding compressed sawdust which is produced during the working of natural dried wood. The compactness of the material is guaranteed by the lignin contained in the wood itself and allows pellets to be produced without glue or binders.
  • Page 12 2 - INSTALLATION INSTRUCTIONS FOREWORD The installation position must be chosen according to the room, to the smoke extraction system, to the chimney flue. Check with local authorities whether there are any restrictive regulations in force regarding the combustion air inlet, the smoke outlet system, the flue or the chimney cap.
  • Page 13 2 - INSTALLATION INSTRUCTIONS FOREWORD This chapter on the Smoke Flue has been produced in reference to the prescriptions of European regulations (EN13384 - EN1443 - EN1856 - EN1457). The chapter provides indications for installing an efficient and correct smoke flue but is under no circumstances to substitute the regulations in force, which the qualified technician must be in possession of.
  • Page 14 2 - INSTALLATION INSTRUCTIONS TECHNICAL CHARACTERISTICS Have the efficiency of the flue checked by an authorised technician. The flue must be sealed against flue gasses, in a vertical direction without narrowing, be made with materials impermeable to smoke, condensation, thermally insulated and suitable to resist normal mechanical stress over time (we recommend fireplaces made of A/316 or refractory material with insulated round section double chamber).

  • Page 16 2 - INSTALLATION INSTRUCTIONS MAINTENANCE The flue must be kept clean, since the deposit of soot or unburned oils reduces the cross-section reducing the draft and thus compromising the efficient functioning of the heater and, if large build-ups accumulate, can catch fire. The flue and chimney must be cleaned and checked by a skilled chimney sweep at least once a year.
  • Page 17 2 - INSTALLATION INSTRUCTIONS EXTERNAL AIR INLET It is mandatory to provide an adequate external air intake that supplies the combustion air required for the product to work properly. The flow of air between the outside and the installation room may be direct, through an inlet in an external wall of the room; or indirect, via air intake from adjoining rooms and connecting permanently with the installation room (see Figure 9 b).
  • Page 18 2 - INSTALLATION INSTRUCTIONS DISTANCE (metres) The air inlet must be at a distance of: 1.5 m UNDER Windows, doors, smoke outlets, cavities, ..1.5 m HORIZONTALLY Windows, doors, smoke outlets, cavities, ..0.3 m ABOVE Windows, doors, smoke outlets, cavities, ..1.5 m AWAY from smoke outlet...
  • Page 19 2 - INSTALLATION INSTRUCTIONS EXAMPLES OF CORRECT INSTALLATION 1. Installation of Ø150mm flue with hole for the passage of the tube increased by: minimum 100 mm around the tube if next to non flammable parts such as cement, brick, etc.; or minimum 300 mm around the tube (or as prescribed by data tags) if next to flammable parts such as wood etc.
