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 Service. Use only 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 be worn before having them replaced. It is important to perform regular maintenance.
1-WARNINGS AND WARRANTY CONDITIONS RULES FOR INSTALLATION The product in question is a stove that uses wood pellets. Below is a list of 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.
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.
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.
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.
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 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 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. Once the check/maintenance has been performed, request a signed report stating that the system is safe.
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).
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 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 INSTRUCTIONS 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.

4-INSTALLATION AND ASSEMBLY PREPARATION AND UNPACKING The Primula/Gardenia and Orchidea/Margherita stoves are delivered with two different types of packing: GARDENIA and PRIMULA stoves come in 1 pack • It contains the stove and also the steel sides with the profiles (fig.1) The ORCHIDEA and MARGHERITA stoves come in 2 packs • One contains the stove • One contains the ceramics (fig.2).
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. If possible, unpack the stove near the chosen place of installation. The packaging materials are neither toxic nor harmful, and therefore no particular disposal measures are required.
4-INSTALLATION AND ASSEMBLY 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). Two screws secure the bracket (C) on the stove and two secure the bracket (C) to the side (B). Repeat the same operation for both sides. Reposition the cast iron top.
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.
4-INSTALLATION AND ASSEMBLY CERAMIC SIDES INSERTION (ORCHIDEA AND MARGHERITA) Remove, on the upper part, the cast iron top (A). Take the six ceramic sides (B) from the box and insert them onto the profile (C) in correspondence of the guide, from the top downwards. Repeat the same operation for both sides. Reposition the cast iron top. SIDES INSERTION We recommend using small velcro felt disks, to be applied to the ends of the ceramics to prevent contact between them.
5-PLUMBING CONNECTION PLUMBING SYSTEM CONNECTION IMPORTANT! If installation of the product involves interaction with another, pre-existing system complete with heating equipment (gas boiler, methane boiler, diesel boiler, etc.), contact qualified personnel, who subsequently will be responsible for conformity of the system in compliance with the applicable law in force.
5-PLUMBING CONNECTION CONNECTION DIAGRAM FOR GARDENIA-MARGHERITA HYDRO STOVE A1 A2 C E 3/4”M heating water delivery 3/4”M heating water return 3/4”M 3 bar 1/2” M safety valve 3/4”M system draining and emptying SYSTEM CONNECTIONS 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.
5-PLUMBING CONNECTION SYSTEM FILLING To fill the system, the stove can be equipped with an end piece (optional) with a check valve (D), for manual filling of the heating system (if the optional is not installed, the filling tap on the main boiler will be used). During this operation, any air in the system is released from the automatic vent valve located under the top. 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).
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: • • • • • Hardness of water circulating in the system, to prevent problems of incrustation and limescale, especially in the domestic water heat exchanger. (> 25° French).
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.
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.
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. This is absolutely normal as the structure is made of laminated steel and must not be considered a defect.
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. Do not pour the pellets up to the gasket because otherwise the door does not close properly, so the stove is not airtight and the alarm is triggered.

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. Technical Dept.
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. It provides a closer match between the heating temperature requested of the boiler and what it actually provides. POS.1-2 EXTERNAL THERMOSTAT POS.5 EARTHING POS.3-4 PUFFER/BOILER PROBE POS.
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). To activate external thermostat if any see the relative section.
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.
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 • If the shutdown time is not already memorised, it proposes a start-up time in + 10 minutes. • A timer programme switches the boiler off at 24:00 of one day and another programme switches it on at 00:00 of the next day: the boiler stays on.
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.
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” option one automatically enables the auto-eco function (it cannot be deactivated). The room probe/external thermostat are not taken into account.
11-SAFETY DEVICES AND ALARMS SAFETY DEVICES The product is supplied with the following safety devices PRESSURE SWITCH Monitors pressure in the smoke duct. It is designed to shut down the pellets feed screw in the event of an obstructed flue or significant back-pressure. (wind) SMOKE TEMPERATURE PROBE Detects the temperature of the smoke, thereby enabling start-up or stopping the product when the temperature drops below the preset value.
11-SAFETY DEVICES AND ALARMS TAMPERING WITH THE SAFETY DEVICES IS PROHIBITED If the product is NOT used as described in this instruction manual, the manufacturer declines all liability for any damage caused to persons and property.
11-SAFETY DEVICES AND ALARMS ALARM ALERTS Whenever an operating condition other than that designed for the regular operation of the boiler occurs, there is an alarm condition. The control panel gives information on the reason of the alarm in progress. A sound signal is not envisioned for alarms A01-A02 only so to not disturb the user in the event of pellets running out in the hopper during the night. Panel alert Type of problem Solution A01 The fire does not ignite.
11-SAFETY DEVICES AND ALARMS NORMAL SHUTDOWN (on the panel: OFF with flashing flame) If the shutdown key is pressed or if there is an alarm signal, the boiler goes into the thermal shutdown phase which entails the automatic execution of the following stages: • It stops pellets loading • The room fan (if provided) maintains the set speed until the smoke T reaches 100°C, then it automatically sets itself at the minimum speed until it reaches the shutdown temperature • The smoke fan sets itself at maximum spe
12-RECOMMENDATIONS FOR A SAFE USE RECOMMENDATIONS FOR A SAFE USE ONLY A SUITABLE INSTALLATION ACCORDING TO THE UK BUILDING REGULATIONS (ADJ) AND A PROPER MAINTAINANCE AND CLEANING OF THE PRODUCT CAN ASSURE YOU THE CORRECT FUNCTIONALITY AND A SAFE USE OF YOUR STOVE(ONLY FOR UK). We wish to notify you that we have been made aware of incidents involving domestic heating pellet stoves resulting from the stoves having been incorrectly installed or inadequately maintained.
