1-WARNINGS AND WARRANTY CONDITIONS SPARE PARTS In the event of a malfunction, consult the retailer who will forward the call to the Technical Assistance Department. Only use original spare parts. The retailer or service centre can provide all necessary information regarding spare parts. We do not recommend waiting for the parts to get worn out before having them replaced.
2-INSTALLATION 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 11
2-INSTALLATION FOREWORD The installation position must be chosen according to the room, smoke extraction system and 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 chimneypot. The manufacturer declines all responsibility in the event of installations that do not comply with the laws in force, incorrect room air exchange, electrical connection non-compliant with the standards and inappropriate use of the appliance.
Page 12
2-INSTALLATION FOREWORD The Flue chapter has been drawn up with reference to the provisions of European Standards (EN13384 - EN1443 - EN1856 - EN1457). The chapter provides indications for installing an efficient and correct 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 unburnt oils reduces the cross-section reducing the draught and thus compromising the efficient operation of the stove 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 inlet 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 (preferable solution see Figure 9 a);...
Page 17
2-INSTALLATION DISTANCE (metres) The air inlet must be at a distance of: 1.5 m BELOW 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 AT A DISTANCE from smoke outlet CONNECTION TO THE FLUE...
Page 18
2-INSTALLATION 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 rating plate) if next to flammable parts such as wood etc.
