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.
2-INSTALLATION 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.
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.
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).
2-INSTALLATION ROOF AT 60° ROOF AT 45° B B C C D D E A F 60° A = MIN. 2.60 metres B = DISTANCE > 1.20 metres C = DISTANCE < 1.20 metres D = 0.50 metres ABOVE HIGHEST POINT E = 2.10 metres F = REFLUX ZONE FIGURE 5 A 45° A = MIN. 2.00 metres B = DISTANCE > 1.30 metres C = DISTANCE < 1.30 metres D = 0.50 metres ABOVE HIGHEST POINT E = 1.50 metres F = REFLUX ZONE E F FIGURE 6 DIMENSIONING The drop in pressure (draft) of a flue depends on its height.
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. Once the inspection/maintenance has been performed, request a written report that the system is safe.
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). Adjoining areas may not include sleeping areas, garages or general areas with a fire hazard.
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 The connection between the flue and the appliance must be via a smoke duct that conforms with EN 1856-2.
2-INSTALLATION EXAMPLES OF CORRECT INSTALLATION 1 U F E V I 2 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. In both cases, install suitable insulation between the flue and the ceiling.

21-RECOMMENDATIONS FOR SAFE USE ONLY CORRECT INSTALLATION AND APPROPRIATE MAINTENANCE AND CLEANING OF THE APPLIANCE CAN GUARANTEE CORRECT OPERATION AND SAFE USE OF THE PRODUCT. We would like to inform you that we are aware of cases of malfunctioning of domestic pellet-fuelled heating products, mainly due to incorrect installation and use, as well as inadequate maintenance. We would like to assure you that all of our products are extremely safe and certified according to European standards of reference.
22-CLEANING EXAMPLE OF A CLEAN BRAZIER EXAMPLE OF A DIRTY BRAZIER Only by properly servicing and cleaning the product is it possible to ensure its safety and correct operation. CAUTION! All the cleaning operations of all parts must be performed with the product completely cold and the plug disconnected. Disconnect the product from the 230V power supply before performing any maintenance operation. The product requires little maintenance if used with certified good quality pellets.
21-RECOMMENDATIONS FOR SAFE USE REMEMBER THAT ONLY A CORRECTLY POSITIONED AND CLEAN BRAZIER CAN GUARANTEE SAFE IGNITION AND OPTIMAL OPERATION OF YOUR PELLET PRODUCT. IN CASE OF FAILED IGNITION AND AFTER ANY OTHER LOCK STATE OF THE PRODUCT, IT IS ESSENTIAL TO EMPTY THE BRAZIER BEFORE EVERY RESTART. For the brazier to be cleaned properly, remove it from its housing completely and thoroughly clean all the holes and the grate on the bottom.
21-RECOMMENDATIONS FOR SAFE USE PERIODIC CLEANING PERFORMED BY A QUALIFIED TECHNICIAN CLEANING THE HEAT EXCHANGER AND THE LOWER COMPARTMENT Half-way through the winter season, but especially at the end, the compartment through which the exhaust smoke passes will need to be cleaned. This cleaning process is mandatory in order to facilitate the general removal of all combustion residue, before it becomes very difficult to remove it due to the humidity compacting it over time.
21-RECOMMENDATIONS FOR SAFE USE CLEANING THE UPPER EXCHANGER Remove top “V” when the stove is cold. Remove the three bolts “r” and slacken off “r1” to rotate the plate “p”; then remove conveyor ”U”. Now remove the four bolts “x” and take off the cast iron exchanger “S”. Remove gasket “T”. Now clean the walls of the hearth with a stiff rod or a bottle brush, so that the dirt falls into the lower compartment. CAUTION! If necessary, replace the seals.
21-RECOMMENDATIONS FOR SAFE USE CLEANING THE LOWER COMPARTMENT At this point you can remove the four screws “k”, the plate “G” and the gasket “H” and then clean the lower compartment where all the dirt deposits of the previous cleaning have accumulated. Even in this case, if necessary, replace the gasket “H”. k G H k CLEANING THE SMOKE EXHAUST SYSTEM AND GENERAL CHECKS Clean the smoke extractor system, especially around the “T” joints, elbows and any horizontal sections of the smoke duct.
21-RECOMMENDATIONS FOR SAFE USE PERIODICAL CHECK OF THE DOOR CLOSURE Make sure the door closure ensures a correct sealing action (with the “paper sheet” test) and that when the door is closed, the closing block (X in the figure) does not protrude from the sheet metal to which it is secured. For some products it will be necessary to disassemble the cladding to be able to assess the anomalous protrusion of the block when the door is closed.
21-RECOMMENDATIONS FOR SAFE USE END-OF-SEASON SHUTDOWN At the end of each season, before switching the product off, it is recommended to remove all the pellets from the hopper with a vacuum cleaner with a long pipe. When not in use the appliance must be disconnected from the mains power supply. It is recommended to remove the power cable for additional safety, especially in the presence of children.
