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. 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 ISO 17225-2. (formerly EN 14961). 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 1.2% of the weight (A1 less than 0.7%).

• 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.

2-INSTALLATION INSTRUCTIONS

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 INSTRUCTIONS

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).

Installation of the product is not permitted:

• 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;

• in rooms in which the decrease in pressure during use, as measured between the pressure outside and the pressure in the room, is greater than 4 Pa.

The product may not be installed in rooms used as sleeping areas, bathrooms, garages or in rooms that present a re hazard in general.

BOILER ROOM

Check that the room meets the requirements and provisions of the standards in force. There must also be a ow of at least enough air in the room for normal combustion. Vents must be installed in the walls of the room that meet the following requirements:

• Increase the cross-section by at least 6 cm2 for each 1 kW (859.64kcal/h) The minimum cross-section of the opening must not, however, measure less than 100 cm. The cross-section can be calculated using the following relations: S = K * Q ≥ 100 cm

Where “S” is in cm2, “Q” in kW, “K” = 6 cm2/kW

• The opening must be located at the base of an external wall, preferably opposite the one with the outlet for combusted gases.

Heat-sensitive or ammable objects cannot be stored near the product; keep such objects at a minimum distance of 80 cm from the outermost point of the product.

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

Have the eciency of the ue checked by an authorised technician. The ue or chimney is vital to the correct functioning of a forced draft solid fuel heating appliance, given that boilers with high performance have cooler fumes with consequently weaker draft and the possible formation of condensation. It is therefore essential that the ue meets all construction standards and is always maintained in perfect condition. 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 either case, ensure to include an inspection cap (AT) or inspection door (AP) and a suitable device for collecting condensation - FIG.1. It is prohibited to connect more than one wood/pellet or any other type of appliance (vent cowling...) to the same ue.

2-INSTALLATION INSTRUCTIONS

TECHNICAL CHARACTERISTICS

Flues serving a pellet/wood fuelled appliance must meet the following requirements:

• made of materials that are suciently resistant to mechanical stress, heat, the action of the products of combustion and their vapours.

• made of materials that are impermeable to fumes, condensation, be thermally insulated and resistant to normal mechanical stress over time

• go in a vertical direction and deviate no more than 45° from the vertical axis and be free of choke points

• be suited to the specic operating conditions of the product and have CE marking (EN1856-1, EN1443).

• Be of the correct size to suit the draft/smoke extraction requirements necessary for the product to work properly (EN13384-1)

• Be suitably caulked externally to avoid condensation and reduce the cooling of the smoke.

• Be at least category T400 (or greater if the appliance requires) and resistant to soot res.

We recommend in particular to check on the data tags of the ue (in accordance with EN1856-1, EN1443) the safety distances that must be respected in presence of passing combustible materials and the type of insulating material to be used. These indications must be followed rigorously to avoid serious harm to personnel and surrounding infrastructure. 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. Smoke must be extracted through a single ue (see g. 3) with insulated steel tubes (A) or though an existing ue that complies with the intended use (B). A simple air shaft in cement must be suitably lined. In either case, ensure to include an inspection cap (AT) and/or inspection door (AP) and a suitable device for collecting condensation - FIG.1. It is prohibited to connect more than one wood/pellet or any other type of appliance (vent cowling...) to the same ue.

2-INSTALLATION INSTRUCTIONS

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 a minimum Ø150mm.

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).

Page 18

2-INSTALLATION INSTRUCTIONS

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 qualied chimney sweep at least once a year. Once the maintenance has been performed, request a written declaration that the device is safe. Failure to clean the system jeopardises the 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).

Use smoke ues of 100mm diameter and silicon seals or similar seals that can resist 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.

We recommend in particular to check the data tags of the ue for the safety distances that must be respected in presence of combustible materials and the type of insulating material to be used. These indications must be followed rigorously to avoid serious harm to personnel and surrounding infrastructure.

CLEANING THE SYSTEM

Install suitable shutters to cut o the tubes from the heating system. To protect the heating system from being damaged by corrosion, incrustation or smoke deposits, it is extremely important, before the appliance is installed, that it be washed according to the UNI 8065 standard (water treatment of thermal systems for civil use) with appropriate products. As standard, RED supplied the product FERNOX PROTECTOR F1 with the product. This provides long term protection against corrosion and calcium build-up for the heating appliance. It prevents the corrosion of the metal parts of the appliance, i.e. the ferrous metals, copper and copper and aluminium alloys. It also reduces the noise produced by the boiler. Refer to the instructions on the product. Cleaning should be performed by a qualied technician. We also recommend the use of FERNOX CLEANER F3 and LEAK SEALER F4, available from our authorised distribution centres. FERNOX F3 is a neutral product for rapid and ecient cleaning of heating appliances. It has been designed to eliminate residue, oily deposits and incrustations from existing appliances of all ages. It can help restore the heating eciency of the boiler and reduce the noise it generates. FERNOX F4 is intended to be used with all heating appliances to seal micro fractures that cause small and inaccessible leaks.

Attention: Failure to clean the thermal system or to use an adequate inhibitor will invalidate the warranty of the appliance and of the other accessories like the pump and valves.

FILLING THE SYSTEM

Fill the system slowly to allow air bubbles to pass through the vent holes of the heating system. For closed circuit heating systems, the lling pressure of the system at cold and the pre-ination pressure of the expansion tank must be the same.

• In open vessel heating systems, direct contact between circulating liquid and air is allowed. During the heating season, the user

must check the circulating water level in the expansion tank regularly. The water level in the circulation system must be kept constant. Practical experience shows that a regular check of the water level must be made every 14 days to maintain a relatively constant level. When necessary, the water level must be topped up when the boiler has cooled to room temperature. This is to avoid and damage being caused to the steel body of the boiler due to thermal stress.

• In systems with an open vessel, the water pressure in the boiler must not be less than 0.3 bar when the system is cool.

• The water used for lling the heating system must be decontaminated and not contain air.

Attention! Do not mix heating water with incorrect concentrations of anti-freeze or anti-corrosion substances! This could damage the gaskets and cause noise during operation. The manufacturer denies any liability for harm caused to persons, animals or objects caused by failure to observe these precautions.

After making all the hydraulic connections, pressure-test the seals by lling the boiler.

This must be done with care by doing the following:

• open the air vent valves of the radiators, boiler and system;

• gradually open the lling tap of the system, making sure that any automatic air vent valves in the system work correctly;

• close the vent valves of the radiators as soon as water comes out;

• use the pressure gauge inserted in the system to check that the pressure reaches a value of approximately 1 bar; for open vessel systems, the water is topped up automatically through the vessel.

• close the lling tap of the system and then open the vent valves of the radiators again to purge any air;

• check the seal of all the connections;

Page 40

7 - HYDRAULIC CONNECTION

• after starting up the boiler for the rst time and bringing the system up to temperature, stop the pumps and repeat the air purging procedure;

• leave the system to cool, and if necessary, restore the water pressure to 1 bar.

NOTE In systems with a closed vessel, where possible, the water pressure in the heating system must not be lower than 1 bar when the system is at room temperature; if this is not the case, use the tap to ll the system. This operation must be performed when the system is cool. The pressure gauge on the system enables you to read the pressure in the circuit.

To ll the system, the hydraulic kit is equipped with a tab, with a stop valve, so that you can manually ll the heating system. During this operation, any air in the system is released from the automatic vent valve located at the top of the body of the boiler.

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

To access the vent valve, lift the central cover and loosen the side cap.

7 - HYDRAULIC CONNECTION

THERMOSTATIC DIVERTER VALVE (COMPULSORY)

The automatic thermostatic diverter valve is used in solid fuel boilers to prevent the return of cold water into the exchanger which would cause condensation to form. The prolonged formation of condensation irreparably damages the heat exchanger. The lack of a device to prevent this invalidates the guarantee. A higher return temperature reduces the formation of condensation of the fumes and extends the life of the boiler. Valves available oer various calibrations. RED recommends the model (see accessories list) at 55°C with hydraulic connections of 1". Once the calibration temperature is reached, the valve opens allowing water to pass between sections "a" - "c" and supplying hot water to the system.

8 - ELECTRICAL CONNECTION

GENERAL PRECAUTIONS

The electrical safety of the system is guaranteed only when this is connected correctly to an ecient earthing system installed in accordance with the safety standards in force: the pipes of the gas, water and heating systems do not constitute a suitable earth system. It is necessary to ensure this essential safety requirement; if in doubt, have a qualied technician test the electrical system with care because the manufacturer of the boiler does not assume responsibility for damage caused by the absence of an earthing system. A qualied technician should check that the electrical system is compatible with the max consumption of the system, checking in particular that the cross-section of the cables of the system is compatible with the power consumption of the loads. The use of any component that requires electrical energy requires compliance with certain essential rules like:

• do not touch the appliance with wet and/or damp parts of the body and/or when barefoot;

• do not pull on the electrical cables;

• do not expose the appliance to the elements (rain, sun, etc.);

• do not allow children or inexperienced persons to use the appliance.

Electrical connection

The installation of additional electrical components of the boiler requires electrical connection to a230V - 50Hzpower supply: This connection must be made in accordance with the CEI standards in force.

Danger! Electrical installation must be entrusted to a single qualied technician. Before making the connections or carrying out any work on the electrical parts, always turn o the power supply and make sure it cannot be turned on again accidentally. Remember that it is necessary to install a bipolar switch in the boiler's electrical power circuit with a distance of 3mm between the main contacts. The switches must be easily accessible to allow quick and safe maintenance.

The power cable must be replaced only by an authorised technician. Failure to observe the above could compromise the safety of the appliance.

Page 43

ELECTRICAL CONNECTION

Open the left side access panel. At the bottom you can access the electrical connection for the boiler and the various electrical connections on the board. Insert the power cable into the socket below the boiler's power switch (A), feed the cable through the hole (B) in the back of the boiler and connect it to the power socket on the wall.

When the boiler is not in use, turn the power switch o.

ELECTRICAL CONNECTION

Page 44

9 - FIRST START-UP

GENERAL PRECAUTIONS

Remove any objects that may burn from the brazier (manual, various adhesive labels or any remaining 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 time to light the ame.

CANCEL THE ALARM FOR THE LIGHTING FAILURE BY HOLDING DOWN BUTTON 1 (ESC). REMOVE THE PELLET LEFT IN THE BRAZIER AND REPEAT THE START-UP.

If after repeated attempts, the ame fails to ignite, despite a regular ow of pellets in the brazier, which must rest snugly against the slots and be clean without any ash incrustations. 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.

Do not touch the boiler during the rst lighting, as it is during this phase that the paint sets. If you touch the paint, you may expose the steel surface.

If necessary, touch up the paint with the spray can of the specic colour. (See ‘’Pellet stove accessories’’).

It is good practice to ensure eective ventilation in the room during the initial start-up, as the boiler 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.

Page 45

9 - FIRST START-UP

Do not stand close to the stove and, as mentioned, air the room. The smoke and smell of paint will disappear after about an hour of operation, however, they are not harmful in any case. The boiler will be subject to expansion and contraction during the lighting and cooling down stages, and may therefore make slight creaking noises. 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 boiler does not reach high temperatures straight away, but to increase the temperature gradually using low power at rst. This will prevent damaging the ceramic or serpentine stone 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.

SETTINGS TO BE CARRIED OUT BEFORE THE INITIAL START-UP

After connecting the power cable to the electrical socket, turn the power switch to the (I) position. Turn the boiler on or o at button 1 on the control panel.

Page 46

9 - FIRST START-UP

LOADING THE PELLETS

The pellets can be loaded either manually or automatically. The tank can contain up to 57 litres or 40 kg of pellets.

Manual Loading:

• Open the top cover of the boiler and pour in the pellets.

Automatic Loading (with remote tank of 100/200 or 400 kg - optional - see accessories):

• At the back of the boiler, remove the perforated panel "U" and attach the duct "V" for the additional tank (optional - see accessories). Then connect the additional tank.

Never remove the protective grate from inside the tank. When loading pellets, keep the bag from coming into contact with hot surfaces.

Page 47

9 - FIRST START-UP

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 IMIDIATLEY.

User Training

In ALL cases the installation and commissioning engineer MUST carry out a thorough handover of the appliance to the homeowner / end user. The following elements should be covered to the satisfaction of the end user. Failure to do this may result in unsafe use of the appliance:

• Explanation of the appliance and how it works

NOTES ON USE OF THE TIMER

• The timer always starts the boiler with the last temperature and ventilation settings (or with the default settings at 20°C and V3 if they have never been altered).

• The start time can be between 00:00 and 23:50

• If the stop time has not yet been saved, the program proposes a start time at +10 minutes.

• If a timer program turns o the boiler at 24:00 on one day and another program starts it up at 00:00 on the next day: the boiler remains on.

• A program has a start-up and/or shut-down time that overlap the times of another program: if the boiler is already on, the start has no eect while OFF turns o the boiler.

• When the boiler is on and the timer is active, pressing the OFF key turns o the boiler; the boiler then restarts automatically at the next time of the timer.

• When the boiler is o and the timer is active, pressing the ON key turns on the boiler; the boiler then stops automatically at the next time of the timer.

SLEEP FUNCTION (main menu)

AUTO ECO MODE

For activation of the "Auto Eco" mode and time settings, see paragraphs 8 f and 8 g respectively. The ''ECO stop T'' can be adjusted to ensure correct operation in the various environments in which the boiler can be installed and to avoid constant stopping and starting when the room temperature is subject to sudden change (drafts, poorly insulated rooms, etc.). The ECO stop procedure is activated automatically when all the power recall devices included in the "system conguration" are satised: room temperature probe/external thermostat (congurations 1-2-3), ow switch (conguration 2), thermostat/ntc (10 kß3435) puer (conguration 4-5) or thermostat/ntc (10 k ß3435) boiler (conguration 2-3). If all the devices present are satised, the time begins to decrease "T ECO o" (10 minutes default, can be changed in the "Settings" menu). During this phase, the panel alternates between displaying ON with a small ame and Crono (if active) - Eco active. The minutes counting down to the Eco Stop are shown at the top of the display. The ame moves to P1 and remains there until the set "T Eco Stop" time reaches zero, and if the conditions are still satised, turns o the boiler. The ECO stop count is cancelled if one of the devices recalls power. When the boiler begins to turn o, the panel shows: O - Eco Active - ashing small ame. When the boiler turns o, OFF-ECO appears on the display with the ame symbol o. The following conditions have to be met simultaneously for the ECO to restart:

• Power recall

• 5 minutes have passed since shut-down.

• TH2O < TSetH2O.

• If the power is recalled by the domestic hot water (DHW), the 5' are ignored and the boiler starts up as required.

NOTE: In conguration 4 - 5 the Auto Eco mode is enabled automatically. Also when in conguration 2 - 3, with the 'summer' function set, it is enabled automatically. Where it is prescribed that it should be enabled, the mode cannot be disabled.

i - Auxiliary boiler

An additional module (optional) must be installed to allow the start-up of an auxiliary boiler when the main boiler is o or has been stopped due to an alarm. The default settings have this function disabled. To enable the function, go to the settings menu.

l - Pellet Recipe

This function is for adapting the boiler to the type of pellet in use. As there are many types of pellet available on the market, the operation of the boiler can vary considerably according to the quality of the fuel. When the pellets clog up the brazier due to excess loading of fuel or when the ames are high even at low power, or when the ames are low, it is possible to decrease/increase the amount of pellets in the brazier: Available values:

-3 = A decrease of 30% on the factory setting.

-2 = A decrease of 20% on the factory setting.

-1 = A decrease of 10% on the factory setting. 0 = No changes. 1 = An increase of 5% on the factory setting. 2 = An increase of 10% on the factory setting. 3 = An increase of 15% on the factory setting.

Edit the recipe as follows:

• Press the "menu" key.

• Use the arrow keys to scroll through and select "Settings"

• Press “menu” to conrm.

• Scroll with the arrows and select "Pellet recipe''

• Press “menu” to conrm.

• Alter the % with the + - keys.

• Press ''menu'' to conrm and ''esc'' to exit.

m - Fumes rpm % ventilation

In the event the installation presents problems in extracting smoke (lack of draft or even pressure in the duct), it is possible to increase the smoke and ash extraction speed. This change resolves all the potential problems related to pellets clogging in the brazier and deposits forming at the bottom of the brazier itself caused by poor quality fuel or fuel that produces a lot of ash. The extraction speed may be altered between -30% to +50%, with increments of 10 percent at a time. Negative variation can be necessary if the ame is too low.

To alter this parameter, proceed as follows:

• Press the "menu" key.

• Use the arrow keys to scroll through and select "Settings"

• Press “menu” to conrm.

• Scroll with the arrows and select "Fumes rpm Var."

11 - SAFETY DEVICES AND ALARMS

SAFETY DEVICES

The product is tted with the following safety devices

PRESSURE SWITCH

Monitors pressure in the smoke duct. It is designed to shut down the pellet feed screw in the event of an obstructed ue or signicant back-pressure. (caused by 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 the running of the boiler.

CONTACT THERMOSTAT IN THE BOILER

If the temperature exceeds the preset safety level, it immediately shuts down the running of the boiler.

WATER TEMPERATURE SENSOR

When the water reaches the stop temperature (85°C) the probe automatically instructs the boiler to turn o "OFF Stand-by".

ELECTRICAL SAFETY

The boiler is protected against violent changes in current by a general fuse located in the control panel at the back of the boiler. Other fuses that protect the electronic boards are found on the latter.

SMOKE FAN

If the fan stops, the electronic board shuts o the supply of pellets in good time, and an alarm message is displayed.

GEAR MOTOR

If the reduction 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

When a power cut is less than 10" the boiler returns to its previous operating state; if it is more, it executes a cooling/re-ignition cycle.

FAILED START-UP

If the fuel fails to ignite during the start-up phase, the boiler will go into alarm status.

ANTI-FREEZE FUNCTION

If the probe in the boiler detects a water temperature of less than 5°C, the circulation pump is automatically activated to keep 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 keep it from seizing up.

Boiler stop

The following conditions may cause the product to be stopped:

• Overheating of the structure and pellet hopper

• Overheating of the water in the boiler

• High pressure of the outlet fumes (read on the pressure switch) and possible obstruction of the outlet. The control panel will indicate the cause of the alarm and sound an acoustic warning. In this situation, the automatic shut-down sequence is activated. When this sequence is initiated, any attempt to restart the system will be ineective.

Safety thermostat with manual rearming at 95°C

The boiler enters a state of safety ALARM called "A03" Thermostat alarms, caused by high water temperature. To cancel the alarm status, the thermostat must be rearmed manually. Only when the boiler has cooled, remove the upper cover "C" and use a tool "F" at least 30 cm long inserted through the hole with the arrow to press the reset button; you will hear the thermostat click. The manually rearmed thermostat has now been reactivated. Replace the cover "C".

Page 65

11 - SAFETY DEVICES AND ALARMS

ALARM SIGNALLING

When a condition occurs other than the one expected for regular operation of the boiler, an alarm is triggered. The reason for the alarm is given on the control panel. The sound signal is not enabled for alarms A01-A02 in order not to disturb the user when there is an absence of pellets in the night tank.

Panel signalling type of problem Solution

A01

The ame does not light Check the level of pellets in the tank.

Check that the brazier is correctly positioned in its seat and has no build-up or unburned material. Make sure the ignition plug warms up. Thoroughly empty and clean the brazier before restarting.

A02

The ame is extinguished unexpectedly. Check the level of pellets in the tank.

A03

Thermostats alarm

The temperature of the pellet hopper or the water temperature exceeds the safety threshold.

Wait until the end of the cooling phase, stop the alarm and re-ignite the boiler setting the supply of fuel to minimum (SETTINGS menu - pellet recipe). If the alarm persists, contact the service centre.

A04

Smoke overtemperature The set smoke threshold has been exceeded. Reduce

the load of pellets (SETTINGS menu - Pellet recipe).

A05

recognised.

Service

Routine maintenance warning (does not seize) When this blinking message appears upon start-up, it

means it is time to carry out scheduled maintenance. Call the assistance 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.

Page 66

11 - SAFETY DEVICES AND ALARMS

To reset the alarm, press and hold key 1 (ESC) for a few seconds. The boiler checks whether the cause of the alarm is ongoing. In the rst case, the alarm continues to be displayed, in the second case it turns OFF. If the alarm persists, contact a service centre.

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

When the shutdown key is pressed, or when there is an alarm signal, the boiler enters the thermal extinguishing phase which involves automatic execution of the following phases:

• Stop pellet loading

• The smoke extractor fan is is activated at maximum speed and remains on for a xed period of 10 minutes, at the end of which if the smoke T has dropped below the stop threshold, the fan stops, otherwise it will continue to operate at minimum speed until the temperature drops below the threshold.

• If the boiler has been shutdown regularly but, due to thermal inertia, the smoke temperature exceeds the threshold again, the shutdown phase will be repeated at minimum speed until the temperature falls.

BLACKOUT with boiler ON

In the event of a blackout, the boiler does the following:

• Blackout of less than 10": continues the work in progress;

• After a loss of power of more than 10'' which occurred when the boiler was on, or during ignition, you can restore the boiler to its previous operating condition when power returns as follows:

1. Cool the boiler by activating the smoke extractor at minimum speed for 10' then proceed to the next step;

2. Restore the boiler to the operating condition prior to the blackout.

During phase 1, the panel shows ON BLACK OUT. During phase 2, the panel shows Start-up. If during phase 1 the system receives manual user commands from the control panel, it stops the blackout restoration sequence and begins the start-up or shutdown commanded by the user.

BLACKOUT OF MORE THAN 10'' DURING EXTINCTION OF BOILER

If the boiler experiences a loss of power greater than 10'' while it is shutting down, when power is restored to the boiler, it will automatically turn on in shutdown mode, even if the smoke temperature has fallen below 45°C in the meantime. This phase can be skipped by pressing key 1 (esc) (skips to start-up) and pressing it again (recognises that the boiler is o).

12-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 use, as well as inadequate 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.

Page 68

13 - MAINTENANCE AND CLEANING

DAILY OR WEEKLY CLEANING PERFORMED BY THE USER

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 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 EMPT Y 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. 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.

13 - MAINTENANCE AND CLEANING

CLEAN THE EXCHANGER AND THE COMPARTMENT BENEATH THE BRAZIER EVERY 2/3 DAYS

Cleaning the exchanger and the compartment beneath the brazier is a simple operation but very important if the boiler is to maintain optimal performance.

We therefore recommend cleaning the internal exchanger every 2-3 days, performing these simple operations in sequence:

• Activate the "CLEANING" function - with the boiler o press - menu, select "Settings", with the arrows <> select "Cleaning", conrm with the "Menu" key, activate the cleaning "ON" with the + - keys. This procedure starts the smoke extractor on the maximum setting to expel the soot that becomes dislodged when the exchanger is cleaned.

• Clean the pipe unit - Using the hook provided, shake the rods located beneath the cover "B" rmly 5-6 times. This should remove the soot that has deposited on the smoke ducts of the exchanger during normal use of the boiler (g. 1).

• Deactivate the "CLEANING" function - this function is deactivated automatically after two minutes. If you need to stop the function sooner, press the "Esc" key.

• Clean the smoke conveyor compartment (g.2) - The boiler is equipped with a removable ash tray "H" which collects any accumulations of soot and ash.

• When done cleaning, close the cover and ash tray.

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

CLEANING THE EXCHANGER AND PIPE UNIT

CLEANING THE UPPER COMPARTMENT

With the boiler cool and after removing the covers (see paragraph on panel removal); loosen the 4 M6 screws "x" on the right and left and lift the cover "V" (g.3).

The three pipes have now been extracted (g.4). Using a rod or a brush for cleaning bottles, clean inside the pipe unit and the pipes, removing any ash deposits (g.5). Check the cover seal and replace it if necessary.

ATTENTION: the exchanger must be cleaned at the end of the season by an authorised technician so that any worn seals may be replaced.

CLEANING THE LOWER COMPARTMENT

Remove the brazier "V", lower the lever "E" and take out the tray "H". Clean the brazier and tray removing any ash and vacuum any ash or soot that may have accumulated under the tray. Check the seal of the door seal and replace it if necessary.

This general cleaning must be performed at the end of the winter season to make it easier to remove and combustion residue.

CLEANING OF THE SMOKE EXTRACTOR COMPARTMENT

Open the access panel on the right side, and remove the two screws "s" at the bottom right. Lower the window "L" and use the vacuum cleaner to remove any ash that has accumulated on the extractor fan.

13 - MAINTENANCE AND CLEANING

CLEANING OF SMOKE DUCT AND GENERAL CHECKS: Clean the smoke extractor duct, especially around the T joints, bends and any horizontal sections. For information on cleaning the ue, contact a chimney sweep.

Check the integrity of the ceramic bre seals on the door of the boiler. 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 system must be cleaned depends on the use of the boiler and the type of installation. We recommend relying on an authorized service centre for end-of-season cleaning and maintenance, they will carry out all of the previously mentioned work and make a general check of the stove's components.

END-OF-SEASON SHUTDOWN

At the end of the season, before shutting down the boiler, we recommend removing all pellets from the hopper with a vacuum cleaner with an extension. When starting up the boiler at the beginning of the season, if the control panel display fails to light up when you press the power switch (located on the back of the boiler), it could mean that the service fuse needs replacing. There is a fusebox at the back of the boiler underneath the power socket. Open the fusebox cover with a screwdriver and replace the fuse if necessary (3.15 A delayed) - seek assistance from an authorised and qualied technician.

CHECKING THE INTERNAL COMPONENTS

ATTENTION! The internal electromechanical components must only be checked by qualied personnel whose technical expertise includes combustion and electricity.

We recommend that an annual maintenance service is carried out with a scheduled service contract. This service is essentially a visual and functional inspection of the following components: The following is a summary of the checks and/or maintenance that are indispensable for the correct operation of the product.

• Gearmotor

• Smoke extractor fan

• Smoke probe

• Ignition spark plug

• Automatic rearm pellet thermostat

• Manual rearm water thermostat

• Room/water temperature probe

• Motherboard

• Fuses protecting panel-motherboard
