2 - INSTALLATION INSTRUCTIONS RULES FOR INSTALLATION The product in question is a stove that uses wood pellets. Below is a list of the European regulations regarding the installation of the product: EN 12828 Heating systems design. IEC 64-8 Electrical systems with rated voltage not exceeding 1000 V AC and 1500 V DC. EN 1443 General chimney regulation EN 1856-1 metal smoke ducts EN 1856-2 metal smoke extraction channels...
Page 11
2 - INSTALLATION INSTRUCTIONS 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 12
2 - INSTALLATION INSTRUCTIONS 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.
Page 13
2 - INSTALLATION INSTRUCTIONS 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 14
2 - INSTALLATION INSTRUCTIONS 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 INSTRUCTIONS 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 chimney must be cleaned and checked by a skilled chimney sweep at least once a year.
Page 17
2 - INSTALLATION INSTRUCTIONS 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 18
2 - INSTALLATION INSTRUCTIONS 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...
Page 19
2 - INSTALLATION INSTRUCTIONS EXAMPLES OF CORRECT INSTALLATION 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.
4 - UNPACKING PREPARATION AND UNPACKING The packaging consists of a recyclable cardboard box according to RESY standards, recyclable EPS foam inserts, wooden pallets. All packaging materials can be reused for similar use or disposed of as urban solid waste, in accordance with current regulations. After having removed the packaging make sure the product is intact.
5 - POSITIONING The product, as indicated in figure 1 consists of a single packaged unit. After removing all the packaging, check that the stove is complete and not damaged. If in doubt, contact the retailer. Therefore, the end user is responsible for product storage, disposal or possible recycling in compliance with the relative applicable laws in force.
6 - INSTALLATION AND ASSEMBLY FRONT PANEL Parts packaged separately and to be assembled onto the structure: • top “B” (next page) • front panel “A” Take panel “A”, bring it near the structure and lock it into place with the two upper screws “v” and lateral screws “s”.

6 - INSTALLATION AND ASSEMBLY SIDE PANELS Side panels “R” are secured to the structure with hinges on one side and a magnet on the other side. Just pull the door towards you to open the side doors.
Page 27
6 - INSTALLATION AND ASSEMBLY PANEL INSIDE THE SIDE PANEL For any work inside the stove, side “T” inside side panel “R” can be removed. To remove “T”, remove the seven screws “s”. Technical Dept. - All rights reserved - Reproduction is prohibited...
Page 28
6 - INSTALLATION AND ASSEMBLY POSITIONING ASH PAN “P” Ash pan “P”, used to remove the ash from the upper exchanger, is installed on the right-hand side of the stove. If due to space requirements, the stove is placed in an area where the ash pan cannot be easily opened on the right-hand side, it can be moved to the left-hand side (see instructions on the next page).
Page 29
6 - INSTALLATION AND ASSEMBLY There is a plug “K” in the same position on the left-hand side. Remove the two screws that secure it to the structure and move the ash pan on this side. Put the plug on the right-hand side to close the hole. The ash pan has the same function whether it is placed on the right- or the left-hand side.

6 - INSTALLATION AND ASSEMBLY LOADING THE PELLETS Fuel is loaded from the upper part of the stove by lifting the door. Pour the pellets into the tank. This is easier if performed in two steps: Pour half of the contents into the tank and wait for the fuel to settle on the bottom. Then pour in the rest.
Page 33
6 - INSTALLATION AND ASSEMBLY SAFETY PROCEDURE TO FOLLOW IF ANY SMOKE SPILLAGE IS SEEN WITHIN THE ROOM OR THE APPLIANCE SUFFERS FROM AN EXPLOSIVE IGNITION PLEASE TURN OFF THE APPLIANCE, VENTILATE THE ROOM AND CONTACT THE INSTALLER/ SERVICE ENGINEER IMIDIAT- LEY.
Page 34
6 - INSTALLATION AND ASSEMBLY OPENING/CLOSING THE DOOR OF THE FIREBOX ATTENTION! The door must be securely closed for the stove to work correctly! To open the door, insert a cold hand into the hole in the handle, lift and pull towards you.
Page 35
6 - INSTALLATION AND ASSEMBLY CONDUIT FOR THE AUXILIARY TANK (optional) It is possible to purchase a conduit to be fastened with using four screws to the back of the stove, in line with the knock-out panel (first the square and then the round piece) to be removed. This conduit makes it possible to insert pellets into the tank through an auxiliary tank (not supplied).
7 - HYDRAULIC CONNECTION HYDRAULIC CONNECTION IMPORTANT! The connection of the stove to the plumbing system must be carried out ONLY by specialised personnel who are capable of carrying out installation properly in compliance with current standards in the country of installation. The manufacturer will not be held responsible for damage to persons or property in the event of failed operation if the aforementioned warning is not complied with.

7 - HYDRAULIC CONNECTION CONNECTING THE SYSTEM Make the connections to the corresponding fittings shown in the diagram on the previous page. Make sure the pipes are not placed under tension or undersized. IT IS STRONGLY RECOMMENDED TO WASH THE ENTIRE SYSTEM BEFORE CONNECTING THE STOVE IN ORDER TO GET RID OF RESIDUES AND DEPOSITS.
Page 40
7 - HYDRAULIC CONNECTION To ensure the valve vents, it is advisable to loosen the grey cap one turn and leave the red cap blocked (see figure). The filling pressure of the system WHEN COLD must be 1 bar. During operation, if the system pressure drops (due to evaporation of dissolved gases in the water) to values lower than the minimum indicated above, the user must use the filling tap to bring the pressure back up to its normal pressure.
8 - ELECTRICAL CONNECTION ELECTRICAL CONNECTION Connect the supply cable coming from the circuit board to an electrical wall socket. The main switch must only be activated to switch the stove on; otherwise, it is advisable to keep it switched off. It is recommended to disconnect the power cable when the stove is not used.
