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. The market oers dierent types of pellets with characteristics that vary according to the wood mixtures used. The most common diameter on the market is 6 mm (although 8 mm diameter is available too) with a length, on average, of between 3 and 40 mm. A good quality pellet has a density of between 600 and 750 or more kg/metres cubed and a water content that accounts for 5 to 8% of its weight. Pellets have technical advantages besides being an ecological fuel, as the wood residue is used completely, thereby achieving cleaner combustion than that of fossil fuels. Good-quality wood has a caloric value of 4.4 kW/kg (15% moisture, after about 18 months of seasoning), whereas that of pellets is 4.9 kW/kg. To ensure good combustion, the pellets must be stored in a dry place and protected from dirt. Pellets are usually supplied in 15 kg bags, therefore, storing them is very convenient.

Good quality pellets guarantee good combustion, thereby decreasing harmful emissions into the atmosphere.

The poorer the quality of the fuel, the more often the internal parts of the brazier and combustion chamber must be cleaned.

The main quality certications for pellets currently available on the European market guarantee that the fuel complies with class A1/A2 according to EN14961-2. These certications include, for example, ENPlus, DINplus, Ö-Norm M7135, and in particular, guarantee the following characteristics:

• caloric value: 4.6 ÷ 5.3 kWh/kg.

• Moisture content: ≤ 10% of the weight.

• Percentage of ash: max 1.5% of the weight.

• Diameter: 6±1/8±1 mm.

• Length: 3÷40 mm.

• Content: 100% untreated wood without the addition of binding substances (max 5% bark).

• Packaging: in sacks made from ecologically compatible or biologically decomposing material.

The company strongly recommends using certied fuel for its products (ENplus, DINplus, Ö-Norm M7135). Poor quality pellets or others that do not comply with the characteristics specied previously may compromise the operation of your product and can therefore render the guarantee and product liability invalid.

PRECAUTIONS REGARDING INSTALLATION

IMPORTANT! Product installation and assembly must be carried out by qualied personnel.

The product must be installed in a suitable place that allows easy access for it to be opened regularly and for routine maintenance to be performed. The installation area must be:

• suitable to enable the appliance to operate correctly.

• Equipped with an adequate smoke extraction system.

• Equipped with adequate ventilation from outside.

• Equipped with 230V 50 Hz power supply with an EC compliant earthing system.

IMPORTANT! The product must be connected to a chimney that expels the smoke at the highest point of the building. The chimney must be of suitable dimensions, caulked, and tted with a condensation collector for collecting the water vapour that can form due to the high performance of the appliance and the consequently low temperatures of the outgoing fumes. The chimney must comply with regulations in force. The holes of the external air inlet and the smoke outlet pipe must be drilled before positioning the product.

THE OPERATING AREA

The boiler must be installed indoors in an area well protected from atmospheric elements. The surface on which it stands and/or support points must have sucient load bearing capacity to support the total weight of the appliance, its accessories and covers. To ensure the appliance works well, we recommend installing the boiler detached from any walls or furniture, and with good air circulation to allow eective ventilation for the appliance. The product should be located in an area that allows sucient space for normal use and maintenance operations.

The volume of the room should be no less than 15 m3.

It is essential that an adequate outdoor air intake is provided that supplies the air for combustion needed for the product to function correctly. These air inlets must be arranged so that it is impossible for them to be obstructed. Protect the inlets with grilles, metal mesh, etc., without reducing the net cross-section.

Remember that the ventilation grilles always have the useful cross-section in cm2 indicated on one side. When choosing the grille and size of the inlet, check that the useful cross-section of the grille is larger or equal to the section required for product operation.

The ow of air between the outside and the room of installation may be direct, through an inlet in an external wall of the building; or indirect, through the intake of air from rooms adjoining and connecting permanently with the room of installation. Adjoining areas may not include sleeping areas, garages or general areas that present a re hazard. For air ducts, up to 3m increase the cross-section by approximately 5%, while for ducts that run for longer increase it by 15%.

IMPORTANT! The air ow can also be drawn from an adjoining room to that of the room where the product is installed, provided the air can ow freely through permanent openings to the outside; avoid connection to sleeping areas and rooms that present a re hazard in general.

Page 13

2-INSTALLATION

POSITIONING AND RESTRICTIONS

In the case of simultaneous installation with other heating appliances, provide appropriate air inlets for each one (according to the instructions of each product).

The product cannot be installed (except for sealed or closed operation appliances with external ducted combustion air intake):

• in bedrooms or bathrooms;

• in rooms where there are liquid fuel appliances with continuous or intermittent operation that draw the combustion air from the room they are installed in;

• in rooms where there are B-type gas heating appliances, with or without domestic hot water production and interconnecting rooms;

• where another heating appliance is installed without an independent air ow.

It is forbidden to place the product in an explosive atmosphere.

MINIMUM DISTANCES

It is recommended to install the stove detached from any walls and/or furniture, with a minimum clearance to allow eective aeration of the appliance and a good distribution of heat in the room. Observe the distances from ammable or heat-sensitive objects (sofas, furniture, wood panelling, etc..) as specied below. The front distance from ammable materials must be at least as set out in the product’s technical data table. If particularly delicate objects are present, such as furniture, curtains or sofas, increase the stove clearance accordingly.

If the oor is made of wood, it is recommended to t a oor protection sheet in compliance with the Standards in force in the country of installation.

LOTUS Non-ammable walls Flammable walls

Hydro

A = 5 cm B = 5 cm

A = 10 cm B = 10 cm

If the oor is made of combustible material, it is recommended to use protection made of non-combustible material (steel, glass...) that also protects the front from falling combusted material during cleaning operations. The appliance must be installed on a oor with adequate load capacity. If the existing construction does not meet this requirement, one must take appropriate measures (for example a load distribution plate).

CONNECTION OF THE SMOKE EXHAUST DUCT

When making the hole for the passage of the smoke discharge pipe, one must take into account the possible presence of ammable materials. If the hole must be made through a wooden wall or thermolabile material, the INSTALLER MUST rst of all use the appropriate wall tting (minimum diameter 13 cm) and suitably insulate the pipe of the product that passes through it using adequate insulating materials (1.3 - 5 cm thick with minimum thermal conductivity 0.07 W/m°K). The same minimum distance must be applied if the pipe of the product must pass through vertical or horizontal sections near the thermolabile wall. It is recommended to use an insulated double-wall pipe in external sections in order to prevent condensation from forming. The combustion chamber works in negative pressure.

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 ecient and correct smoke ue but is under no circumstances to substitute the regulations in force, which the qualied technician must be in possession of. Check with local authorities whether there are any restrictive regulations in force regarding the intake of air for combustion, the smoke extraction system, the ue or the chimney. The company declines all liability relating to the poor functioning of the boiler if this is due to the use of an insuciently sized ue in violation of regulations in force.

SMOKE FLUE

The ue or chimney is of great importance for the proper operation of a solid fuel-burning heating appliance with natural draught, as modern heating appliances have high eciency with cooler ue gasses and consequently less draught, it is therefore essential that the ue is built up to standard and always kept in perfect working order. A ue that serves a pellet/wood fuelled appliance must be at least category T400 (or greater if the appliance requires, and resistant to soot res. Smoke must be extracted through a single ue made of insulated steel (A) or an existing ue that complies with the intended use (B). A simple air shaft in cement must be suitably lined. In both solutions there must be an inspection cap (AT) and/or inspection hatch (AP)

- FIG.1. It is prohibited to connect more than one wood/pellet or any other type of appliance (vent cowling...) to the same ue.

The stove must be connected to a ue pipe or an internal or external vertical duct conforming to EN 1856-1-2 to suit the appliance and types of fuels to be burnt – refer to detailed guidance in sections 2, 3 and 4 in ADJ (ONLY FOR UK).

TECHNICAL CHARACTERISTICS

Have the eciency of the ue checked by an authorised technician. The ue must be sealed against ue 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 replaces made of A/316 or refractory material with insulated round section double chamber). Be suitably insulated externally to avoid condensation and reduce smoke cooling. It should be separated from combustible or ammable materials with an air gap or insulating materials: check the distance specied by the manufacturer of the replace according to EN1443. The chimney opening must be in the same room as the appliance, or at most in the adjoining room, and have a soot and condensation collection chamber beneath the opening, and be accessible via a watertight metal hatch.

DIMENSIONING

The drop in pressure (draft) of a ue depends on its height. Check the drop in pressure with the values indicated in the technical characteristics. The minimum height of the chimney is 3.5 meters.

The interior cross-section of the ue can be circular (best variation), square or rectangular (the ratio between the interior sides must be ≤1.5) with the sides joined with a minimum radius of 20 mm. The dimension of the cross-section must be minimum Ø100mm.

The cross-sections/lengths of the chimneys shown in the technical data tables are indications for correct installation. Any alternative congurations must be correctly dimensioned in accordance with the general method of calculation of UNI EN13384-1 or other proven eciency methods.

Below is a list of some ues available on the market:

Steel chimney AISI 316 with double chamber insulated with ceramic bre or equivalent resistant up to 400°C.

Refractory chimney with double insulated chamber and external lightweight concrete cladding with cellular material such as clay.

Traditional square-section clay chimney with insulating empty inserts.

Avoid products with an internal rectangular section where the larger side is 1.5 times the smaller side (e.g. 20x40 or 15x30).

MAINTENANCE

The ue must be kept clean, since the deposit of soot or unburned oils reduces the cross-section reducing the draft and thus compromising the ecient functioning of the heater and, if large build-ups accumulate, can catch re. The ue 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. Failure to clean the system jeopardises its safety.

CHIMNEY

The chimney is a crucial element for the heating appliance to work properly: we recommend a wind proof chimney (A), see Figure 7. The area of the opening for smoke extraction must be at least double the cross-section of the smoke duct/ue system, and arranged so

that smoke extraction is ensured even in strong wind. The chimney must prevent rain, snow or animals from entering the chimney. The height of outow into the atmosphere must be beyond the reux zone created by the shape of the roof or any obstacles near the outlet (see Figures 2-3-4-5-6).

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 ow 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 re hazard. During installation one must check the minimum clearances required for air intake from outside. Take into account the presence of doors and windows that could interfere with the proper ow of air to the stove (see diagram below). The air intake must have a minimum total net area of 80 cm2: the surface must be increased accordingly if within the room there are other active generators (for example: electric fan for stale air extraction, kitchen hood, other stoves, etc...), which could cause cause depression in the room. One must verify that, with all the equipment on, the pressure drop between the room and the outside does not exceed a value of 4 Pa (also for Oyster appliances if combustion air has not been suitably ducted outside). If necessary increase the intake section of the air inlet, which must be made at oor level and always protected with a bird-proof outer protection grid and in such a way that it cannot be obstructed by any object.

It is possible to connect the air required for combustion directly to the outside air inlet, with a pipe of at least Ø50mm, with maximum length of 3linear metres; each pipe bend shall be considered equivalent to a linear metre. To attach the pipe see the back of the stove. For stoves installed in studio ats, bedrooms and bathrooms (where allowed), it is mandatory to connect the combustion air outside. In particular for sealed stoves the connection must be sealed in order not to compromise the overall sealed characteristic of the system.

Use smoke ducts with a diameter of 80mm or 100mm depending on the type of system, with silicone gaskets or similar gaskets that can withstand the high operating temperatures of the appliance (min. T200 class P1). The use of exible metal tubes in bre cement or aluminium is prohibited. For direction changes, we always recommend the use of a T joint with an inspection cap allowing easy access for cleaning the tubes. Always ensure that the inspection cap is replaced and hermetically sealed with the seal in tact after cleaning. It is prohibited to connect more than one appliance to the same smoke duct, or the discharge from overhead cowling. It is prohibited to extract the products of combustion directly through the wall, whether into indoor spaces or outdoors. The smoke duct must be a minimum distance of 400 mm from ammable or heat-sensitive structures.

SUPPLEMENTARY ISTRUCTIONS ONLY FOR UK

FOR CONNECTION TO THE FLUE PIPE, NOT MORE THAN 150mm OF HORIZONTAL PIPE MUST BE USED AND NOT MORE THAN 4 x 45° bends MUST BE USED. I accordance with UK Building Regulations .

All exterior ue or ue used internaly above 1.8m should be twin wall insulated pipe installed in accordance with ADJ reference page 23 section 1.31 and 1.32 and 1.33 & Hetas regulations.

The external uepipe must have internal dimensions of a minimum of 150mm, and maximum 180mm.

Check with suitable instruments that there is a minimum draught of 5 Pa. on low re and 10pa on high re. The ue must always run under negative pressure and a cold ue pull of – 2>3 pascals must be secured.

4-INSTALLATION AND ASSEMBLY

Therefore, the end user is responsible for product storage, disposal or possible recycling in compliance with the relative applicable laws. Position the product without its cladding and connect it to the chimney. Once the connections are complete, assemble

the cladding (steel sides). If the product must be connected to an exhaust pipe that goes through the rear wall (to enter the chimney), make sure not to force it in. Adjust the 4 feet (J) to level the stove so that the smoke exhaust and the pipe are coaxial. The ceramic sides must not be tted when the feet are adjusted as this is carried out inside the cladding.

Attention!! If the stove smoke outlet is forced or used improperly to lift it or position it, the operation of the stove can be damaged irreparably.

4-INSTALLATION AND ASSEMBLY

ASSEMBLING THE CLADDING ASSEMBLING THE SIDE PANELS

The product is supplied with the ceramic panels packaged separately, therefore unpack all the parts before proceeding with the assembly. Follow the sequence below to assemble the panels:

• lift pellet loading lid A.

• Open door B.

• Remove the two front screws C and the two rear screws C.

• Remove lid D.

• At this point take the three ceramic (side) panels E and insert them as shown in the gure.

The six ceramic side panels belonging to the kit, are all the same and therefore can be inserted equally on the right or left of the stove. One must pay utmost attention when inserting them as the two insertion screws, on the ceramic and on the stove, are dierent and therefore have a direction (detail below).

Page 27

4-INSTALLATION AND ASSEMBLY

ASSEMBLING THE TOP

The top does not require particular fastening as it is only rested on the structure of the product in line with the relative vibration dampers. So once panels E have been tted and piece D reassembled and fastened with the four screws C one can install the ceramic top.

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 qualied personnel, who subsequently will be responsible for conformity of the system in compliance with the applicable law in force. The Company declines all responsibility for damage to persons or things in the event of failed or incorrect operation, if the aforementioned warnings are not complied with.

It is important that ONLY qualied engineers are used to t and commission the appliance in ALL cases. The installing engineer MUST hold a QCF recognised biomass qualication. Any company using sub-contractors MUST ensure they also hold the relevant qualications (ONLY FOR UK).

Make the connections to the corresponding ttings shown in the diagram above. Make sure the pipes are not placed under tension or undersized.

IMPORTANT!!! FLUSH THE ENTIRE SYSTEM BEFORE CONNECTING THE BOILER IN ORDER TO REMOVE RESIDUES AND DEPOSITS. Always install gate valves upstream from the boiler so as to disconnect it from the plumbing system should it be necessary to move it, or when it requires routine and/or special maintenance. Connect the boiler using hoses so that the boiler is not too strictly connected to the system, and to allow slight movements.

5-PLUMBING CONNECTION

HYDRAULIC KIT

The boiler is equipped with a complete kit for the production of domestic water made up of:

• Plate heat exchanger

• A 3-way diverter valve

• Flow switch

• Pipes and ttings for connection

The kit comes preassembled by the manufacturer and it is designed to heat domestic water directly from the home water supply system. When hot water is required and the tap is turned, the internal water ow switch will send a signal to the diverter valve to channel the hot water contained in the boiler to the plate heat exchanger. The temperature of the domestic water highly depends on the temperature of the water inside the heating system. This can be calculated to a good degree of accuracy by taking 10°-15°C away from the value shown on the stove control panel (which is the temperature of the water in the boiler).

If the boiler is in ECOSTOP mode and domestic water is required, after 30 seconds from the request the boiler will automatically begin the start-up process to heat the water inside the boiler and subsequently the domestic hot water.

SYSTEM WASHING

Fit suitable gate valves on the heating system pipes. To protect the heating system from harmful corrosion, fouling or deposits, it is of the utmost importance, before installing the product, to wash the system in compliance with UNI-CTI 8065, using appropriate products such as, for example, Sentinel X300 (new systems), X400 and X800 (old systems) or Fernox Cleaner F3. Complete instructions are provided with the products but, for further clarications, please directly contact the manufacturer SENTINEL PERFORMANCE SOLUTIONS LTD or Fernox COOKSON ELECTRONICS. After ushing the system, to protect it against corrosion and deposits, we recommend the use of inhibitors such as Sentinel X100 or Fernox Protector F1. It is important to check the concentration of the inhibitor after each change to the system and during maintenance as prescribed by manufacturers (specic tests are available at dealers). The discharge of the safety valve must be connected to a collecting funnel for conveying the possible dredges in case of intervention.

Attention: Failure to clean the heating system and to add a suitable inhibitor will void the warranty of the equipment and other accessories such as for example pumps and valves.

SYSTEM FILLING

Filling must be carried out slowly so that air bubbles can get out via the purposely placed outlets on the heating system. In closed circuit heating systems the loading pressure of the system when cold and the expansion tank preloading pressure must be tha same.

• In open tank heating systems, there is direct contact between the circulating liquid and air. During the heating season the end user

must regularly check the level of water circulating in the expansion tank. The content of water in the recycling system must be kept constant. Practical experience demonstrates that the water level must be inspected regularly every 14 days to maintain the water content almost constant. In the event one needs to add water one must carry out the lling process when the boiler has cooled down to room temperature. These precautions aim to prevent the onset of a thermal stress of the steel body of the boiler.

• In systems equipped with an open tank the water pressure in the boiler - when the system is cold - must not fall below 0.3 bar;

• The water used for lling the heating system must be decontaminated and without air.

Attention! Do not mix the heating water with antifreeze or anticorrosion substances in the wrong concentrations! It can damage the seals and cause the onset of noise during operation. The manufacturer declines all responsibility if the damage caused to persons, animals or things is a result of failure to comply with the above.

Once all plumbing connections have been carried out, proceed with the inspection of the seals under pressure, by lling the boiler.

This operation must be done carefully observing the following steps:

• open the radiator, boiler and system air valves;

• gradually open the system lling tap making sure that any automatic air valves installed on the system work properly;

• close the radiator air valves as soon as water starts to come out;

• on the system pressure gauge check that the pressure reaches a value of approximately 1 bar (applicable only for systems equipped with a closed tank - refer to any standards or local regulations that allow it); for open tank systems relling takes place automatically via the same tank;

• close the system loading tap and then bleed air again via the radiator air valves;

• check tightness of all connections;

• after having started the boiler for the rst time and heated up the system, stop the pumps and repeat the air bleeding operations;

Page 32

5-PLUMBING CONNECTION

• let the system cool down and if needed take the water pressure back to 1 bar (applicable only for systems equipped with a closed tank - refer to any standards or local regulations that allow it); for open tank systems relling takes place automatically via the same tank;

NOTE In systems equipped with a closed tank, where possible, the water pressure in the heating system - when the system is cold - must be no less than 1 bar; if under this value, act on the system lling tap. The operation must be carried out when the system is cold. The system pressure gauge enables to monitor the pressure in the circuit.

To ll the system, the boiler is tted with a tap (4), with a check valve, to load the heating system manually. During this operation, any air in the system is released via the air valve located in the upper part of the boiler.

To ensure the valve vents, it is advisable to loosen the side cap (see gure) The lling pressure of the system WHEN COLD must be 1 bar. Upon completion of this lling operation, always close the tap.

6-ELECTRICAL CONNECTIONS

GENERAL PRECAUTIONS

Electrical safety of the system is ensured only when it is properly connected to an ecient 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; if in doubt, request an accurate inspection of the electrical system to be carried out by qualied personnel, because the boiler manufacturer is not responsible for any damage caused by failure to earth the system. Have professionally qualied personnel check the electrical system is suitable for the maximum power absorbed by the heating system, ensuring in particular that the diameter of cables is appropriate for the power absorbed by the loads. The use of any component that is powered by electricity entails compliance with some basic rules such as:

• do not touch the appliance with wet and/or damp body parts and/or bare feet;

• do not pull the electric cables;

• do not leave the appliance exposed to weathering (rain, sun, etc.);

• do not allow the appliance to be used by children or inexperienced persons.

230V electrical power supply connection

Installation of the boiler accessory electrical components requires electrical connection to a 230 V – 50 Hz mains: This connection must be state of the art according to the CEI standards in force.

Hazard! Electrical installation must be carried out by a qualied technician only. Before performing connections or any operation on the electrical parts, always disconnect the power supply and make sure it cannot be accidentally reconnected. Please note that the boiler electrical power line must be tted with a bipolar switch with a contact gap greater than 3 mm, easy to access, in order to make any maintenance operations quick and safe.

The power cable must be replaced by authorised technical personnel. Failure to comply with the provisions listed above may compromise the safety of the appliance.

ELECTRICAL CONNECTION

First connect the power cable to the side of the stove and then to a wall socket. The main switch at the side must only be activated to switch the stove on; otherwise, it is advisable to keep it o.

It is recommended to disconnect the power cable when the stove is not used.

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.

The rst start-up may not be successful as the feed screw is empty and does not always manage to load the required amount of pellets in the brazier in time for the re to be regularly ignited.

CANCEL THE FAILED START-UP ALARM STATUS BY PRESSING AND HOLDING KEY 1 (ESC). REMOVE THE PELLETS FROM THE BRAZIER AND REPEAT START-UP.

If a ame does not ignite after a number of failed start-ups, even though the pellet supply is correct, make sure the brazier is set in place correctly, which must be interlocked in its seat and free from any ash deposits. If no anomaly is found during this inspection, there may be a problem with the product components or installation may not be correct.

REMOVE THE PELLETS FROM THE BRAZIER AND CONTACT AN AUTHORISED TECHNICIAN.

Avoid touching the stove during the initial start-up, as the paint in this stage hardens; by touching the paint, the steel surface may be exposed.

If necessary, touch up the paint with the spray can in the original colour (see the "Accessories for pellet stoves" section).

It is good practice to guarantee eective ventilation in the room during the initial start-up, as the stove will emit some smoke and smell of paint. ATTENTION! Please ensure the brazier is clear of ALL pellets and ash build up following any failed ignitions. Failure to clear out the brazier prior to resetting may result in further failed ignitions or in certain conditions an explosive ignition.

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 stove will be subject to expansion and contraction during the start-up and cooling phases, therefore light creaking noises may be heard.

Page 35

7-INITIAL START-UP

This is absolutely normal as the structure is made of laminated steel and must not be considered a defect. It is extremely important to make sure the product is not immediately overheated and the temperature is increased gradually, initially using low power. This will prevent damaging the ceramic or serpentine tiles, the welds and the steel structure.

DO NOT EXPECT HEATING EFFICIENCY IMMEDIATELY!!!

ATTENTION!

If during operation or initial ignition you encounter smoke spillage in to the room from the appliance or the ue then please switch o the appliance, ventilate the room and contact the installation / service engineer immediately.

OPENING/CLOSING THE DOOR

ATTENTION! The door must be closed properly for the stove to work correctly.

"Use suitable Personal Protective Equipment (e.g. gloves) to open the stove door.

To open the door, lift the hook, as shown in the gure"

SETTINGS TO BE CARRIED OUT BEFORE THE INITIAL START-UP

Once the power cable is connected in the rear part of the stove, turn the switch, also placed at the rear, to position (I). To switch the stove on or o press key 1 on the control panel.

AUTO ECO MODE (see section 8f and 8g)

To activate the “Auto Eco” mode and adjust the time refer to section 8 f and 8 g respectively. The possibility to adjust the "ECO shutdown t" comes from the need to ensure proper operation in the various rooms the stove can be installed in and prevent continuous shutdowns and start-ups in the event the temperature is subject to sudden changes (air currents, poorly insulated rooms, etc.). The ECO shutdown procedure is activated automatically when all the power demand devices involved in the "system conguration" are satised: room probe/external thermostat (congurations 1-2-3), ow switch (conguration 2), puer thermostat/ntc (10 kΩ ß3435) (conguration 4-5) or boiler thermostat/ntc (10 kΩ ß3435) (conguration 2-3). If all devices present are satised the "ECO shutdown t" time decrease starts (by default 10 minutes, it can be changed within the "Settings menu"). During this stage the panel displays ON with a small ame and alternately Chrono (of active) - Eco active. The minutes indicating the countdown for the Eco Stop are shown at the top of the display. The ame goes into P1 and stays there until the programmed "Eco shutdown t" time has elapsed and if the conditions are still satised, it goes into the shutdown stage. The ECO switch o countdown resets if one of the devices boosts power again.

Page 44

8-MENU ITEMS AND OPERATION

When switch o starts the panel displays: O - Eco Active - small ashing ame. Once the stove has reached the o condition, the panel displays OFF-ECO with the extinguished ame symbol. To restart from ECO the following conditions must be satised simultaneously:

• Power demand

• After 5 minutes from the beginning of shutdown.

• TH2O < TSetH2O.

• If the domestic hot water (DHW) demands power the rst 5' are ignored and the stove restarts as needed.

NOTE: In conguration 4 - 5 the Auto Eco mode is enabled automatically. Even when one sets the "summer" function in conguration 2 - 3 it is enabled automatically. In the cases where it is designed to be active, it is not possible to deactivate the mode.

j - Pellet Recipe

This function is for adapting the stove to the pellets that are being used. In fact, as there are several types of pellets on the market, stove operation is extremely variable depending on the fuel quality. In the event the pellets tend to clog the brazier due to an excessive load of fuel or in the event the ame is always high even at low powers and, vice versa if the ame is low one can decrease/increase the amount of pellets in the brazier: The available values are:

-3 = Decrease by 30% compared to factory settings.

-2 = Decrease by 20% compared to factory settings.

-1 = Decrease by 10% compared to factory settings.

0 = No variation. 1 = Increase by 5% compared to factory settings. 2 = Increase by 10% compared to factory settings. 3 = Increase by 15% compared to factory settings.

To change the recipe act as follows:

• Press the “menu” button.

• Scroll to "Settings" using the arrows

8-MENU ITEMS AND OPERATION

OPERATING MODE

The operating mode for hydro stoves is AUTOMATIC only (manual mode is not envisioned). Flame modulation is managed according to the "System conguration" 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.

START-UP

Press key 1 (esc) to begin start-up, the control panel displays ON with a ashing ame. When the ame stops ashing the stove 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. To activate external thermostat if any see the relative section.

POWER OUTPUT

Once the start-up stage is complete the control panel will display ON with a xed ame at level 3 . The subsequent ame modulation at lower or higher powers is managed autonomously and upon reaching the temperatures set in the "System conguration".

9-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 ue or signicant 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.

CONTACT THERMOSTAT IN THE FUEL HOPPER

If the temperature exceeds the preset safety level, it immediately shuts down stove operation.

CONTACT THERMOSTAT IN THE BOILER

If the temperature exceeds the preset safety level, it immediately shuts down stove operation.

WATER TEMPERATURE PROBE

If the water temperature approaches the shutdown temperature (85°C) the probe makes the boiler perform the “OFF Stand-by” automatic shutdown.

ELECTRICAL SAFETY

The product is protected against sudden current surges by a main fuse in the power supply panel on the rear part of the product. Other fuses that protect the electronic boards are found on the latter.

SMOKE FAN

If the fan stops, the electronic board promptly shuts o the pellets supply and an alarm message is displayed.

GEAR MOTOR

If the gear motor stops, the boiler will continue to run until the ame goes out due to lack of fuel and until a minimum level of cooling is reached.

TEMPORARY POWER CUT

If the power cut lasts less than 10" the stove returns to its previous operating status; if it lasts more it carries out a cooling/restart cycle.

FAILED START-UP

If during ignition no ame develops, the boiler will go into alarm condition.

ANTIFREEZE FUNCTION

If the probe in the boiler detects a water temperature of less than 5°C, the circulation pump is automatically activated to prevent the system from freezing.

PUMP ANTI-SEIZURE FUNCTION

If the pump is not used for prolonged periods, it is activated periodically for a few seconds to prevent it from seizing up.

9-SAFETY DEVICES AND ALARMS

ALARM ALERTS

Whenever an operating condition other than that designed for the regular operation of the stove 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 re does not ignite. Check the level of pellets in the tank.

Check that the brazier rests correctly in its seat and has no visible deposits or unburnt pellets. Check whether the ignition plug becomes hot. Empty and clean the brazier before relighting..

A02

The re goes o abnormally. Check the level of pellets in the hopper.

A03

Thermostat alarms

The temperature of the pellets hopper or the water temperature exceed the envisioned safety threshold.

Wait for the cooling stage to end, cancel the alarm and restart the stove setting the fuel loading at minimum (SETTINGS menu - Pellets recipe). If the alarm persists, contact the service centre. Check if the room fan works properly (if present).

A04

Smoke overheating. The set smoke threshold has been exceeded. Reduce

pellets loading (SETTINGS menu - Pellets recipe).

A05

Pressure switches alarm

Smoke pressure switch intervention or water pressure insucient.

Verify chimney obstruction / door opening or hydraulic system pressure.

A08

Abnormal smoke fan operation. If the alarm persists, contact the service centre.

A09

Smoke probe faulty. If the alarm persists, contact the service centre.

A19

Water probe faulty. Water probe disconnected / interrupted / defective /

not recognised.

A20

Puer probe alarm. Puer probe disconnected / interrupted / defective /

not recognised.

Service

Routine maintenance alert (it does not block the system).

When this ashing message appears upon start-up, it means that the preset operating hours have eleapsed before maintenance. Contact the service centre.

ALARM RESET

NEVER open the appliance door whilst the stove is either in the initial startup or on its shut down cycle, pellets will still be smoldering or therefore volatiles may be present. ATTENTION! If during operation or initial ignition you encounter smoke spillage in to the room from the appliance or the ue then please switch o the appliance, ventilate the room and contact the installation / service engineer immediately.

To reset the alarm one must press and hold key 1 (ESC) for a few seconds. The stove performs a check to determine if the cause of the alarm persists or not. In the rst case the alarm will still be displayed, in the second case it will go onto OFF. If the alarm persists, contact the service centre.

Page 60

9-SAFETY DEVICES AND ALARMS

NORMAL SHUTDOWN (on the panel: OFF with ashing ame)

If the shutdown key is pressed or if there is an alarm signal, the stove 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 speed and maintains it for a xed time of 10 minutes, at the end of which if the smoke T has fallen below the shutdown threshold it switches o permanently, otherwise it sets itself at the minimum speed until it reaches such threshold before switching o.

• If the stove was shutdown regularly but, due to thermal inertia the smoke temperature exceeds the threshold again, the shutdown stage restarts at the minimum speed until the temperature goes down.

BLACKOUT WITH THE STOVE ON

In the event of a power cut (BLACKOUT) the stove behaves as follows:

• Blackout below 10”: it returns to its operation in progress;

• In the event of a power cut that lasts over 10" with the stove on or in the start-up stage, when the stove is powered again it goes back to the previous operating condition with the following procedure:

1. It cools down activating the smoke extractor at minimum power for 10' and goes onto the next point;

2. It takes the stove back to the operating condition before the blackout.

During stage 1 the panel displays ON BLACK OUT. During stage 2 the panel displays Start-up. If during stage 1 the stove receives commands from the panel and thus carried out manually by the user, then the stove stops executing the blackout recovery status and proceeds to restart or shutdown as requested by the command.

BLACKOUT ABOVE 10” WITH STOVE IN SHUTDOWN STAGE

In the event there is a power cut that lasts MORE THAN 10” with the stove in the shutdown stage, when the stove is powered again it restarts in shutdown mode even if the smoke temperature has fallen under 45°C in the meanwhile. This last stage can be skipped by pressing key 1 (esc) (it goes into start-up) and by pressing it again (it recognises that the stove is switched o).

10-RECOMMENDATIONS FOR A 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 inappropriate maintenance. We would like to assure you that all of our products are extremely safe and certied according to European standards of reference. The ignition system has been tested with the utmost attention to enhance ignition eciency and to prevent any type of problem, even in the worst operating conditions. In any case, like for any other pellet-fuelled product, our appliances must be installed correctly and undergo regular periodical cleaning and maintenance to guarantee safe operation. Our studies show us that malfunctioning is mainly due to the combination of part or all of the following factors:

• Brazier holes obstructed or brazier deformed, due to lack of maintenance and conditions which can cause delayed ignitions, generating an anomalous production of unburned gases.

• Insucient combustion air due to a reduced or clogged air inlet duct.

• Use of smoke ducts nonconforming to regulatory installation requirements, failing to guarantee an adequate draught.

• Partially clogged chimney, due to lack of maintenance, reducing the draught and making ignition dicult.

• End chimneypot nonconforming to the indications of the instruction manual, and therefore not suitable to prevent potential inverse draught.

• This factor is crucial when the product is installed in especially windy areas, such as costal regions.

The combination of one or more of these factors could generate important malfunctioning conditions. To keep this from occurring, it is fundamental to guarantee that the product is installed in compliance with standards in force. Furthermore it is of the utmost importance to respect the following simple rules:

• Every time the brazier is removed for cleaning, it must always be put back properly in the work position before using the product, completely removing any residual lth left on the support base.

• Pellets must never be loaded in the brazier manually, either before ignition or during operation.

• The accumulation of unburned pellets ensuing a failed ignition must be removed before repeating ignition. Also check that they are fed correctly and that the combustion air inlet/smoke outlet are regular.

• If ignition fails repeatedly, immediately suspend use of the product and contact a qualied technician to check its operation.

Compliance with these indications is absolutely sucient to guarantee proper operation and to avoid any type of problems with the product. If the above-mentioned precautions are not taken, and during ignition the brazier is overloaded with pellets thus generating anomalous smoke in the combustion chamber, carefully follow the indications below:

• Do not disconnect electrical power to the product for any reason whatsoever: this would stop the smoke extractor, releasing smoke into the environment.

• Take the precaution of opening the windows to ventilate the installation room from any smoke in the environment (the chimney might not work properly).

• Do not open the re door: this would compromise regular operation of the smoke extraction system to the chimney.

• Just switch the stove o by acting on the on-o button on the control panel (not the rear power supply socket button!) and move away until smoke has completely evacuated.

• Before attempting re-ignition, clean the brazier and its air passage holes completely of all deposits and unburned pellets. Put the brazier back in place, removing any residue from its support base. If ignition fails repeatedly, immediately suspend use of the product and contact a qualied technician to check its operation and the chimney.

11-CLEANING AND MAINTENANCE

Only a proper maintainance and cleaning of the product can assure you the correct functionality and a safe use of your stove.

ATTENTION! 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 certied high quality pellets.

DAILY OR WEEKLY CLEANING PERFORMED BY THE USER Brazier cleaning

Before ignition, always clean the brazier and remove any ash or incrustation from it that might obstruct the air ow holes, paying attention to hot ash. In the case of ignition failure, or if fuel in the tank runs out, unburned pellets may accumulate in the brazier. Always empty the residue in the brazier before each start-up. Only if ash is completely cold may a vacuum cleaner be used to remove it. In this case, use a suitable vacuum cleaner to remove small sized particles.

REMEMBER THAT ONLY A CORRECTLY POSITIONED AND CLEAN BRAZIER CAN GUARANTEE THE 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 EMPT Y THE BRAZIER BEFORE PROCEEDING TO 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. If good quality pellets are used, you will normally only need to use a brush to restore the optimal operating conditions of the component.

Ash tray cleaning

Remove and empty the ash tray. Wipe away any residual ash before reinserting the tray. Your experience and the quality of the pellets will determine the ash tray cleaning frequency. However, it is recommended not to exceed 2 or 3 days.

CLEANING THE ASH COLLECTION COMPARTMENT

Page 63

11-CLEANING AND MAINTENANCE

CLEAN THE EXCHANGER AND THE UNDERGRATE SPACE EVERY 2/3 DAYS.

Cleaning the exchanger and the undergrate space is a simple operation but very important for always maintaining performance as declared. Therefore we recommend cleaning the internal exchanger every 2-3 days, performing these simple operations in sequence:

• Activate the “CLEANING” function – when the boiler is switched of press - menu, select“Settings”, with the <> arrows select

“Cleaning”, conrm with “Menu”, activate cleaning “ON” by pressing the +- keys. This procedure activates the smoke extraction fan on maximum power to expel the soot that is dislodged when the exchanger is cleaned.

• Clean the pipe unit – Using the cold handle supplied (the cold handle hangs inside the stove door - g.2) shake vigorously the

rods placed under the cover 5-6 times. This will remove any soot that has deposited on the exchanger smoke ducts during normal stove operation.

• Disable the "CLEANING" function - this function is automatically disabled after two minutes. If one needs to stop this function in

advance press the "Esc" key.

• Clean the smoke conveyor compartment (g.3) - The boiler is tted with a removable ash pan designed to collect any soot and

ash build-up.

• Once cleaning is complete close the cover and ash pan.

If such cleaning is not done every 2-3 days the stove could go into alarm caused by ash clogging after several hours of operation.

PERIODIC CLEANING PERFORMED BY A QUALIFIED TECHNICIAN

CLEANING THE EXCHANGER AND PIPE UNIT

CLEANING THE UPPER COMPARTMENT

When the boiler is cold lift the ceramic top; remove screws “O” to the right and left and remove cover “A”. Then remove the the xing screws from drivers “V” and remove boiler cover “B”.

At this point, remove the four turbulators “C” and using a rigid rod or a bottle brush, clean the internal pipe unit and the turbulators, removing all of the accumulated ash. Check the cover gasket and replace it if necessary.

ATTENTION: It is advisable to carry out the cleaning of the upper exchanger at the end of the season and possibly by an authorised technician in order to also replace the gasket located below plug “B”.

CLEANING THE LOWER COMPARTMENT

Remove ash pan “D” and empty it. Lower lever “E” and extract drawer “F”. Remove the ash from the drawer and if needed use a vacuum cleaner to remove any other ash or soot that has built-up under the drawer. Remove brazier “G” and clean it every 2/3 days. Check the seal of the ceramic bre gasket on the plug and replace it if necessary. Check the seal of the door gasket and replace it if necessary. At the end of the season one must clean the compartment under the brazier and the inside of the heat exchanger. This general cleaning should be carried out at the end of the season in order to facilitate the general removal of all combustion residues, without waiting too long, because with time and humidity these residues can become compacted.

Page 65

11-CLEANING AND MAINTENANCE

CLEANING THE SMOKE FAN COMPARTMENT

Remove the four screws that keep the plug fastened on the rear part of the stove and remove any ash deposited on the smoke fan with a vacuum cleaner. Check the seal of the ceramic bre gasket on the plug and replace it if necessary.

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. For information on periodically cleaning the ue, contact a skilled chimney sweep.

Check the seal of the ceramic bre gaskets on the door of the stove. If necessary, order new replacement seals from the retailer or contact an authorized service centre to carry out this task.

ATTENTION: The frequency with which the smoke exhaust must be cleaned depends on the use of the boiler and the type of installation. We recommend contacting an authorised service centre for end-of-season maintenance and cleaning as the abovementioned operations will be performed together with a general inspection of the components.

END-OF-SEASON SHUTDOWN

At the end of season, before shutting down the boiler, we recommend completely removing pellets from the hopper with the use of a

vacuum cleaner with an extension. The service fuse may have to be replaced if the control panel display does not go on when the product is re-started upon pressing the main switch on the rear of the boiler. On the rear of the boiler there is a fuse compartment which is located underneath the supply socket. Use a screwdriver to open the fuse compartment and if necessary replace them (3.15 A delayed).
