2-INSTALLATION INSTRUCTIONS The requirements in this chapter refer to the regulations of the Italian installation Standard UNI 10683. In any case, always comply with 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.

2-INSTALLATION INSTRUCTIONS CONNECTION OF THE SMOKE EXHAUST DUCT When drilling the hole for the smoke exhaust pipe, the possible presence of flammable materials must be considered. If the hole must be made through a wooden wall or thermolabile material, the INSTALLER MUST first use the relative wall fitting (minimum diam. 13 cm) and adequately insulate the pipe of the product that passes through it, using suitable insulating material (1.3 - 5 cm thick with minimum thermal conductivity 0.07 W/m°K).
Page 12
2-INSTALLATION INSTRUCTIONS Always use pipes and fittings with appropriate seals that guarantee tightness. It must be possible to inspect all sections of the flue duct and they must be removable for periodic internal cleaning (T-fitting with inspection hole). Position the product considering all the above requirements and instructions. IMPORTANT! The following conditions must be complied with when connecting the appliance to the chimney: •...

2-INSTALLATION INSTRUCTIONS 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...

2-INSTALLATION INSTRUCTIONS 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.

3-INSTALLATION AND ASSEMBLY ELECTRICAL CONNECTION First connect the power cable on the rear side of the stove and then to a wall socket. The main switch on the rear side must only be activated when the stove is used; otherwise, it is advisable to keep it off. It is recommended to disconnect the power cable when the stove is not used.
Page 26
3-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.
4-OPERATION 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, they are not harmful in any case.
Page 28
