  • Page 10: Installation

    2-INSTALLATION 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 11 If particularly delicate objects are present, such as furniture, curtains or sofas, increase the stove clearance accordingly. If the floor is made of wood, it is recommended to fit a floor protection sheet in compliance with the Standards in force in the country of installation.

  • Page 12 2-INSTALLATION 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 13 2-INSTALLATION 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 15 2-INSTALLATION 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 chimneypot must be cleaned and checked by a qualified chimney sweep at least once a year.
  • Page 16 2-INSTALLATION 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 17 2-INSTALLATION 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 CONNECTION TO FLUE...

  • Page 22: Assembly

    5-ASSEMBLY COMBUSTION AIR (2) During operation a certain amount of air is drawn from the room in which the product is installed and this air must be supplemented through an external air inlet. The combustion air in this product is autonomously drawn directly from the front grille, however, the user can have the air drawn from outside by removing the clamp on the pipe and connecting it directly to outside.

  • Page 24 5-ASSEMBLY The product can be installed at the desired height by constructing a suitable platform. This support must be made of non-flammable material. The company declines all liability for any damage to objects and persons if the above-mentioned precautions are not complied with.
  • Page 25 5-ASSEMBLY HOOD VENTILATION GRILLES FOR NEW CLADDING It is mandatory to install the hood ventilation grilles of the manufacturer or grilles that can guarantee the same functions and the same air passage section. The company cannot be held liable for any damage caused to the structure or the electrical components if this precaution is not complied with.
  • Page 26 5-ASSEMBLY SETTING UP THE CLADDING The product must be fully tested before the cladding is applied. The company cannot be held liable for any damage to the cladding should operating anomalies arise, which were not verified before the cladding was applied to the product. IT IS MANDATORY to check the tightness of all the pipes through which smoke passes (smoke fitting, gaskets and flue coupling) before setting up the cladding.
  • Page 27 5-ASSEMBLY ASSEMBLING THE COMPENSATION FRAME Once the cladding and/or the plasterboard is set up, fit the previously removed compensation frame. This frame intends to finish and cover the gap between the metal structure of the product and the cladding. The frame is assembled by simply opening the door of the product, fitting in the frame as shown in the figure and fastening it to the lateral columns of the structure, inside the door profile, with the four screws supplied.

  • Page 28: First Start-Up

    6-FIRST START-UP BEFORE START-UP GENERAL PRECAUTIONS Remove all components that could burn from the firebox and the glass (instructions, 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 29: Loading The Pellets

    7-LOADING THE PELLETS It is extremely important to make sure the product is not immediately overheated and the temperature is increased gradually starting from the low power. This will prevent damaging the welds and the steel structure. DO NOT EXPECT HEATING EFFICIENCY IMMEDIATELY!!! LOADING THE PELLETS Fuel is loaded from the front tray above the door.
