  • Page 11: 2-Installation Instructions

    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 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. Non-flammable walls Flammable walls PRIMULA/ORCHIDEA GARDENIA/MARGHERITA A = 5 cm A = 10 cm...
  • 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).

  • Page 16 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 25 4-INSTALLATION AND ASSEMBLY The stove body or unit must always be kept in a vertical position when handled and moved by using carts only. Pay particular attention to the door and its glass, protecting them from mechanical knocks that would compromise their integrity. Always handle the product with care.
  • Page 26 ASSEMBLING THE SIDE CLADDING ASSEMBLY OF PROFILES FOR INSERTION OF STEEL SIDES (PRIMULA) Remove, on the upper part, the cast iron top (A). Take the side (B) (make sure it goes into the part under the plugs (F) and secure it to the upper sheet metal of the stove with the bracket (C) and four screws (D).
  • Page 27 4-INSTALLATION AND ASSEMBLY ASSEMBLY OF PROFILES FOR INSERTION OF STEEL SIDES (GARDENIA) Remove, on the upper part, the cast iron top (A). Take the two profiles (B) to be assembled on the front part of the stove (one to the right and one to the left). Make sure that the profile (B) at the bottom enters the hole predisposed for fixing on the base, and that along the side it enters the blade (B1) predisposed in the stove along its entire height.
  • Page 28 4-INSTALLATION AND ASSEMBLY CERAMIC SIDES INSERTION (ORCHIDEA AND MARGHERITA) Remove, on the upper part, the cast iron top (A).

  • Page 31 To allow the valve to vent, it is recommended to loosen the grey cap by one turn and leave the red cap locked (see figure). The filling pressure of the system WHEN COLD must be 1 bar. If during operation the system pressure drops (due to evaporation of gases dissolved in the water) to values lower than the minimum ones indicated above, the user must use the filling tap to bring the pressure back up to its initial pressure.
  • Page 32 5-PLUMBING CONNECTION WATER CHARACTERISTICS The characteristics of the water used to fill the system are very important to prevent the build-up of mineral salts and the formation of incrustations along the pipes, in the boiler and in the heat exchangers. Therefore, please ASK YOUR PLUMBER FOR HIS ADVICE CONCERNING: •...

    6 - ELECTRICAL CONNECTIONS GENERAL PRECAUTIONS Electrical safety of the system is ensured only when it is properly connected to an efficient earthing system made in compliance with the safety standards in force: gas, water or heating systems pipes are not suitable as earth connections. One must check this essential safety requirement;...
  • Page 34: Initial Start-Up

    7 - INITIAL START-UP GENERAL PRECAUTIONS Remove all components that could burn from the brazier and 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 35 7 - INITIAL START-UP Do not stand close to the product 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. The boiler will be subject to expansion and contraction during the start-up and cooling phases, therefore slight creaking noises may be heard.
  • Page 36 7 - INITIAL START-UP LOADING THE PELLETS Fuel is loaded from the upper part of the stove by opening the door. Pour the pellets into the hopper. To ease the procedure carry out the operation in two steps: Pour half of the contents into the hopper and wait for the fuel to settle on the bottom. Then complete the operation by pouring in the rest.

  • Page 51: 10-Operation

    10-OPERATION OPERATING MODE The operating mode for hydro boilers is AUTOMATIC only (manual mode is not envisioned). Flame modulation is managed according to the “System configuration” of the room probe placed on the rear of the appliance (see drawing), by the external thermostat, by the boiler water temperature or by the NTC probes.
  • Page 52 10-OPERATION EXTERNAL THERMOSTAT CONNECTION (e) EXTERNAL THERMOSTAT (not included with the boiler, to be provided by the user) The temperature of the boiler can also be controlled by an external room thermostat. It is located in a central position of the room where the boiler is installed.
  • Page 53 10-OPERATION START-UP Press key 1 (esc) to begin start-up, the control panel displays ON with a flashing flame. When the flame stops flashing the boiler has reached the “power output” operating mode. The room temperature set by default is 20°C, if one wishes to change it act as instructed in the adjustments menu; act likewise to set the heating water temperature and the room fan speed (if envisaged).
  • Page 54 10-OPERATION PROGRAMMED MODE (TIMER) - Main menu Setting the current day and time is essential for the proper operation of the timer. There are six TIMER programmes, for each one the user can decide the start-up and shutdown time as well as the day of the week in which it is active.
  • Page 55 10-OPERATION NOTES FOR TIMER OPERATION • Start-up with the timer always takes place with the last temperature and ventilation settings (or with default 20°C and V3 settings in the event they have never been changed). • Start-up time ranges from 00:00 a 23:50 •...
  • Page 56 10-OPERATION AUXILIARY BOILER (see section 8i) One must install an additional module (optional) to enable start-up of an auxiliary boiler in the event the stove is switched off or in alarm conditions. By default this function is deactivated, if needed activate it to access the settings menu. PELLETS RECIPE (see section 8j) This function is for adapting the stove to the pellets that are being used.
  • Page 57 10-OPERATION SEASON FUNCTION (see section 8p) In configurations 2 and 3, by enabling the “summer” function, the deviation of the 3-way valve to the heating system is inhibited in order to prevent the radiators from heating up, therefore the flow is always directed towards the domestic hot water (DHW) - if envisaged. By activating the “summer”...
