  • Page 8: 2-Fuel

    2-FUEL The instructions in this chapter refer explicitly to the Italian installation regulation UNI 10683. In any case, always observe the regulations in force in the country of installation. 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 9: 3-Installation

    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 10: 4-Flue

    4-FLUE FOREWORD The Chimney Flue chapter has been drawn up with reference to the provisions of European Standards (EN13384 - EN1443 - EN1856 - EN1457). The chapter provides instructions for installing a chimney flue efficiently and properly, but under no circumstances is it a substitute of the Standards in force, which the qualified technician must be in possession of.
  • Page 11 EN1443. The chimney opening must be in the same room as the appliance, or at most in the adjoining room, and have a soot and condensation collection chamber beneath the opening, and be accessible via a sealed metal hatch.

  • Page 13 4-FLUE 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 operation of the stove and, if large build-ups accumulate, can catch fire. The flue and chimney must be cleaned and checked by a qualified chimney sweep at least once a year.
  • Page 14 4-FLUE 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).

The connecting section must extend no more than 4 m horizontally, with a minimum slope of 3% and with a maximum of 3 90% bends (accessible for inspection - do not count the T fitting at the appliance outlet).
  • Page 16 4-FLUE EXAMPLES OF CORRECT INSTALLATION 1. Installation of Ø120mm flue with hole for the passage of the pipe increased by: minimum 100mm around the pipe if next to non flammable parts such as cement, brick, etc.; or minimum 300mm around the pipe (or as required by data tags) if next to flammable parts such as wood etc.

  • Page 22 6-INSTALLATION AND ASSEMBLY Position the product without its cladding and connect it to the chimney. Once the connections are complete, assemble the cladding (ceramic or serpentine sides). If the product must be connected to an exhaust pipe that goes through the rear wall (to enter the chimney), make sure not to force it in. Adjust the 4 feet (J) to level the stove for the smoke exhaust and the pipe to be coaxial.
  • Page 23 6-INSTALLATION AND ASSEMBLY CONNECTION OF THE SMOKE OUTLET PIPE You can choose whether to release the smoke on the rear part or upper part of the product. If you wish to connect the smoke outlet to the upper part, remove the cap with the three screws from under the top. Then insert the pipe until it engages with the smoke fitting.
  • Page 24 6-INSTALLATION AND ASSEMBLY If you wish to connect the smoke outlet to the rear part, turn the T-fitting towards the rear of the product. Then connect the pipes. TURN THE T-FITTING FOR THE REAR SMOKE OUTLET.
  • Page 25 6-INSTALLATION AND ASSEMBLY CONNECTING THE HOT AIR DUCTING The standard product has two fans installed for air distribution with the nozzle directed towards the front part of the stove. Therefore, the first important thing to decide is whether to channel the air or not. In line with this, turn the fan (2) for the air to be released towards the rear part.
  • Page 26 6-INSTALLATION AND ASSEMBLY FAN 2 TURNED FOR REAR AIR. FAN 2 ORIGINAL POS. The air can be channelled by fastening a flexible pipe on the rear part of the product with a clamp, in line with the hole on the upper part. The air can now be released from the front and rear, only from the front or only from the rear.

  • Page 35 6-INSTALLATION AND ASSEMBLY BEFORE START-UP GENERAL PRECAUTIONS Remove all components that could burn from the brazier and the 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 36 6-INSTALLATION AND ASSEMBLY It is good practice to guarantee effective ventilation in the room during the initial start-up, as the stove will emit some smoke and smell of paint. Do not stand close to the stove 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.
  • Page 37 6-INSTALLATION AND ASSEMBLY LOADING THE PELLETS Fuel is loaded by lifting the cover on the upper part of the product. Slowly pour the pellets into the hopper. Be careful as the cover could become very hot. LIFT THE COVER. INSERT THE PELLETS. No other type of fuel other then pellets, in compliance with above-mentioned specifications, is to be inserted into the hopper.
