2-FUEL

The instructions contained in this chapter explicitly refer to the regulations of the Italian installation Standard UNI 10683. In any case, always comply with the regulations in force in the country of installation.

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 offers different types of pellets with characteristics that vary according to the wood mixtures used. The diameter varies between 6 and 8 mm, with a standard length ranging from 5 to 30 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.

While good-quality wood has a calorific value of 4.4 kW/kg (15% moisture, after about 18 months of seasoning), whereas that of pellets is around 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.

15 Kg BAG OF FUEL

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 certifications for pellets currently available on the European market guarantee that the fuel complies with class A1/A2 according to EN14961-2. An example of these certifications are the ENPlus , DINplus , Ö-Norm M7135, and they guarantee that they are followed according to these characteristics:

• calorific value: 4,6 ÷ 5.3 kWh/kg.

• Water content: max 10% of weight.

• Percentage of ashes: max 1.5% of weight.

• Diameter: 5 ÷ 6 mm.

• Length: max 40 mm.

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

• Packaging: in sacks made from ecologically compatible or bio-degradable material.

The company strongly recommends using certified fuel for its products (ENplus, DINplus, Ö-Norm M7135).

Poor quality pellets or others that do not comply with the characteristics specified previously may compromise the operation of your product and can therefore make the guarantee and product liability invalid.


3-INSTALLATION

FOREWORD

The installation position must be chosen according to the room, to the smoke extraction system, to the chimney flue. Check with local authorities whether there are any restrictive regulations in force regarding the combustion air inlet, the smoke outlet system, the flue or the chimney cap. The manufacturer declines all responsibility in the event of installations that do not comply with the laws in force, incorrect room air exchange, electrical connection non-compliant with the standards and inappropriate use of the appliance. The installation must be carried out by a qualified technician, who must issue a declaration of conformity of the system to the purchaser and will assume full responsibility for final installation and consequent good operation of the product.

In particular one must ensure that:

• there is a suitable combustion air inlet and smoke outlet in compliance with the type of product installed

• other stoves or devices installed do not cause depression in the room where the product is installed (for sealed appliances only, a maximum of 15 Pa of depression in the room is allowed)

• when the product is switched on there is no reflux of smoke in the room

• fumes extraction takes place in total safety (sizing, smoke seal, distances from flammable materials..).

We especially recommend checking the data tags of the flue for the safety distances that must be observed in presence of combustible materials and the type of insulating material to be used. These indications must be followed strictly to prevent serious harm to people and the integrity of the home.

The installation of the appliance must ensure easy access to clean the appliance itself, the smoke outlet pipes and the flue. It is forbidden to install the stove in rooms with a fire hazard.

Installation in studio flats, bedrooms and bathrooms is only allowed with sealed or closed appliances equipped with suitable combustion air ducting directly outside. Always maintain adequate distance and protection in order to prevent the product from coming into contact with water.

In the event there are several appliances installed, the external air inlet must be sized accordingly.

MINIMUM DISTANCES

It is recommended to install the stove detached from any walls and/or furniture, with a minimum clearance to allow effective aeration of the appliance and a good distribution of heat in the room. Observe the distances from flammable or heat-sensitive objects (sofas, furniture, wood panelling, etc..) as specified. The front distance from flammable materials must be at least 1 metre.

If particularly delicate objects are present, such as furniture, curtains or sofas, increase the stove clearance accordingly.

If the floor is made of wood, it is recommended to fit a floor protection sheet in compliance with the Standards in force in the country of installation.

If the floor 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 floor with adequate load capacity.

If the existing construction does not meet this requirement, one must take appropriate measures (for example a load distribution plate).

4-FLUE

FOREWORD

The Chimney Flue chapter has been drawn up with reference to the provisions of European Standards (EN13384 - EN1443 - EN1856 -

EN1457).

The chapter provides instructions for installing a chimney flue efficiently and properly, but under no circumstances is it a substitute of the

Standards in force, which the qualified technician must be in possession of. Check with local authorities whether there are any restrictive regulations in force regarding the combustion air inlet, the smoke outlet system, the flue or the chimney cap.

The company declines all liability relating to the poor functioning of the stove if this is due to the use of an insufficiently sized flue in violation of the Standards in force.

SMOKE FLUE

The flue 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 efficiency with cooler flue gasses and consequently less draught, it is therefore essential that the flue is built up to standard and always kept in perfect working order. A flue that serves a pellet/wood fuelled appliance must be at least category T400 (or greater if the appliance requires so) and resistant to soot fires. Smoke must be extracted through a single flue made of insulated steel (A) or an existing flue that complies with the intended use (B).

A simple air shaft made of cement must be suitably lined. In both solutions there must be an inspection cap (AT) and/or inspection hatch

(AP) - FIG.1.

It is forbidden to connect more than one wood/pellet-burning appliance or of any other kind (vent hoods... ) to the same flue.

TECHNICAL CHARACTERISTICS

Have the efficiency of the flue checked by an authorised technician.

The flue must be sealed against flue gasses, in a vertical direction without narrowing, be made with materials impermeable to smoke, condensation, thermally insulated and suitable to resist normal mechanical stress over time (we recommend fireplaces made of A/316 or refractory material with insulated round section double chamber). Be suitably insulated externally to avoid condensation and reduce smoke cooling. It should be separated from combustible or flammable materials with an air gap or insulating materials: check the distance specified by the manufacturer of the fireplace 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.

SIZING

The depression (draught) of a flue depends on its height. Check the depression with the values indicated in the technical characteristics.

The minimum height of the chimney is 3.5 meters.

The interior cross-section of the flue can be round (best), square or rectangular (the ratio between the internal 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 chimneys must be correctly sized in accordance with the general method of calculation of UNI EN13384-1 or other methods of proven efficiency.

Below is a list of some flues available on the market:

AISI 316 steel chimney with double chamber insulated with ceramic fibre 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

Avoid products with an internal rectangular section empty inserts.

where the larger side is 1.5 times the smaller side (e.g.

20x40 or 15x30).

EXCELLENT GOOD POOR VERY POOR


3-INSTALLATION

MAINTENANCE

The flue must be kept clean, since the deposit of soot or unburned oils reduces the cross-section reducing the draft and thus compromising the efficient operation of the stove and, if large build-ups accumulate, can catch fire. The flue and chimney must be cleaned and checked by a qualified chimney sweep at least once a year. Once maintenance has been performed, request a written declaration that the system is safe.

Failure to clean the system jeopardises safety.

CHIMNEY CAP

The chimney cap is a crucial element for the heating appliance to work properly: we recommend a wind proof chimney cap (A), see Figure

7.

The area of the openings for smoke extraction must be at least double the cross-section of the smoke duct/flue 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 outflow into the atmosphere must be beyond the reflux area due to the shape of the roof or any obstacles near the outlet (see Figures 2-3-4-5-6).

3-INSTALLATION

EXTERNAL AIR INLET

It is mandatory to provide an adequate external air intake that supplies the combustion air required for the product to work properly. The flow of air between the outside and the installation room may be direct, through an inlet in an external wall of the room; or indirect, via air intake from adjoining rooms and connecting permanently with the installation room (see Figure 9 b). Adjoining areas may not include sleeping areas, garages or general areas with a fire 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 flow 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 a 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. If necessary increase the intake section of the air inlet, which must be made at floor level and always protected with a bird-proof outer protection grid and in such a way that it cannot be obstructed by any object.

LOADING THE PELLETS

Fuel is loaded from the upper part of the stove by lifting the door. Pour the pellets into the hopper.

This is easier if performed in two steps:

Pour half of the contents into the hopper and wait for the fuel to settle on the bottom.

Then pour in the rest.

Never remove the protection grid inside the hopper. When loading, do not let the pellet bag come into contact with hot surfaces.

No other type of fuel other than pellets is to be inserted into the hopper, in compliance with above-mentioned specifications.

Store the spare fuel at an adequate safe distance.

Do not pour pellets directly onto the brazier but only into the hopper.

Most of the stove surfaces are very hot (door, handle, glass, smoke outlet pipes, hopper door etc.), therefore it is recommended to avoid coming into contact with these parts without appropriate protective clothing.

LOADING THE PELLETS

CONDUIT FOR THE AUXILIARY TANK (optional)

It is possible to purchase conduit to be fastened, using four screws, to the back of the stove, in correspondence of the knock-out panel, first the square and then the round piece is to be removed.

This conduit makes it possible to insert pellets into the tank through an auxiliary tank (not supplied).

IMPORTANT!!!

CLEAN THE ENTIRE SYSTEM BEFORE CONNECTING THE STOVE, IN ORDER TO REMOVE ALL RESIDUE AND DEPOSITS.

Upstream from the stove, always install shutters 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 stove using hoses so that the stove is not too strictly connected to the system, and to allow slight movements.



CONNECTING THE SYSTEM

Make the connections to the corresponding fittings shown in the diagram on the previous page. Make sure the pipes are not placed under tension or undersized.

IT IS STRONGLY RECOMMENDED TO WASH THE ENTIRE SYSTEM BEFORE CONNECTING THE STOVE IN ORDER TO GET RID

OF RESIDUES AND DEPOSITS.

Upstream from the stove, always install shutters 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 stove using hoses so that the stove is not too strictly connected to the system, and to allow slight movements.

The pressure discharge valve (C) is always connected to a water drain pipe. The pipe must be adequate to support the water's high temperature and pressure.

CLEANING THE SYSTEM

It is mandatory for the connections to be easy to disconnect by way of unions with rotating connection.

Install suitable shutters to cut off the tubes from the heating system. Assembling the safety valve on the system is compulsory.

In order to protect the heating system from damage caused by corrosion, incrustation or deposit build-up, it is important to clean the appliance before installation, using suitable products, in compliance with Standard UNI 8065 (water treatment of thermal plants for civil use) .

The use of FERNOX PROTECTOR F1 (available at our authorised centres) product is recommended, this provides long term protection against corrosion and calcium build-up for heating systems. 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 qualified technician.

We also recommend the use of FERNOX CLEANER F3 and LEAK SEALER F4, always available from our authorised distribution centres.

FERNOX F3 is a neutral product for rapid and efficient cleaning of heating appliances. It has been designed to eliminate residues, oily deposits and incrustations from existing appliances of all ages. It can help restore the heating efficiency 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.

FILLING THE SYSTEM

To fill the system, the stove can be equipped with an end piece (optional) with a non-return valve (D) , for manual filling of the heating system (if the option is not installed, the filling tap on the main boiler will be used). During this operation, any air in the system is released from the automatic vent valve located under the top.

To ensure the valve vents, it is advisable to loosen the grey cap one turn and leave the red cap blocked (see figure). The filling pressure of the system WHEN COLD must be 1 bar . During operation, if the system pressure drops (due to evaporation of dissolved gases in the water) to values lower than the minimum indicated above, the user must use the filling tap to bring the pressure back up to its normal pressure.

For proper operation of the stove WHEN HOT , the pressure in the boiler must be 1.5 bar .

To monitor system pressure, the end piece (optional) is equipped with a pressure gauge (M) .

Upon completion of this operation, always close the tap.

WATER CHARACTERISTICS

The characteristics of the water used to fill the system are very important to prevent the build-up of mineral salts and the formation of incrustations along the pipes, in the boiler and in the heat exchangers.

Therefore, please GET YOUR PLUMBER'S ADVICE CONCERNING:

• Hardness of water circulating in the system, to prevent problems of incrustation and limescale, especially in the domestic water heat exchanger. (> 25° French).

• Installation of a water softener (if water hardness exceeds 25° French).

• Filling the system with treated water (demineralised).

• Possibly providing an anti-condensation circuit.

• Installation of plumbing bumpers to prevent banging along the fittings and pipes.

If you have very extensive systems, with a large amount of water, or which require frequent refilling, the installation of water softening systems.

It should be remembered that incrustations drastically reduce performance due to low thermal conductivity.


8-ELECTRICAL CONNECTION

ELECTRICAL CONNECTION

First connect the power cable to the back of the stove and then to a wall socket.

The main switch must only be activated to switch the stove on; otherwise, it is advisable to keep it switched off.

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

ELECTRICAL STOVE CONNECTION

STOVE POWER SUPPLY

After connecting the power cable to the back of the stove, turn the switch at the back to position ( I ).

The luminous switch button will light up.

The switch on the back of the stove is used to power the system.

On the rear of the stove there is a fuse holding compartment which is located underneath the supply socket. Use a screwdriver to open the

8-PRECAUTIONS BEFORE START-UP

GENERAL PRECAUTIONS

Remove any objects that may burn from the brazier (manual, various adhesive labels or any polystyrene).

Check that the brazier is positioned correctly and rests properly on the base.

The first 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 flame.

CANCEL THE FAILED IGNITION ALARM. REMOVE THE PELLETS LEFT IN THE BRAZIER AND REPEAT THE START-UP.

If after repeated attempts, the flame fails to ignite, despite a regular flow 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 first 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 specific colour. (See "Pellet stove accessories").

It is good practice to ensure effective ventilation in the room during the initial start-up, as the boiler will emit some smoke and smell of paint.

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 first.

This will prevent damaging the ceramic or serpentine stone tiles, the welds and the steel structure.

DO NOT EXPECT HEATING EFFICIENCY IMMEDIATELY!!!

PRELIMINARY OPTIONS

Hydro Air stoves are characterised by the presence of a heating hydraulic circuit and a room air fan for distributing hot air.

The possibility of deviating the hydraulic circuit towards a finned copper exchanger based on user request or automatically to double the amount of heat distributed to the room air (also see HYDRO AIR SETTINGS MENU).

Room fan

The speed can be set manually or automatically.

In manual mode the speed, from 0 to 5, is chosen by the user from the control panel. The fan is only activated if the air output temperature exceeds 42°C and is deactivated when it goes below 40°C; while at speed 0 the fan is off.

In automatic the stove adjusts fan speed in order to obtain stable output air temperature (approximately 55°C in Hydro Air On mode and

The Hydro Air function can be activated/deactivated manually or managed automatically (factory default setting).

In Hydro-Air On mode the internal three-way valve is switched so that the water, before going towards the system, passes through the front radiator, transferring heat to the environment through the fan up to 6 kW (at maximum power with water temperature at 70°C).

In Hydro-Air Off mode the internal three-way valve is switched so that stove water goes directly to the system, without passing through the front radiator. In this case power released to the environment may reach 3 kW.

In Hydro-Air Automatic mode the three-way valve is managed in an intelligent way by the electronic control in order to release maximum power to the room only when there is an actual heat request from the stove probe. If there is no request from the room, the valve is switched as in OFF mode.

To enter the function: from the settings menu - press ok (E key), press the D key (arrow key) and scroll up to Hydro-air, press OK (E key) and activate the HYD-AIR

This function is for adapting the stove to the type of pellet in use. As there are many types of pellet available on the market, stove operation can vary considerably according to the quality of the fuel. When the pellets clog up the brazier due to excess loading of fuel, vice-versa if the flame has a tendency to shut-off, it is possible to decrease/increase the amount of pellets in the brazier:

The available values compared to factory settings are:

+15% +10% + 5%; 0%; -10% -20% -30%

To modify the pellet recipe, in sequence, press: from the Settings menu- press ok (E key), press the D KEY (arrow) scroll up to pellet recipe and press OK (E key) and enter the function, using the "C" and "D" keys to modify the parameter and press Ok ("E" key).

ACTIVE +

The pellet type is not a problem because the stoves are equipped with the Active system and automatically adapt to pellet of any length with a diameter of 6-8 mm. Effective and efficient combustion is independent from any type of connection to the flue which, with traditional systems, may constitute a problem during the installation phase.

Thanks to an internal sensor, the stove is extremely reliable and precise. Combustion air is constantly adjusted based on the quantity of pellets present in the brazier, guaranteeing an effective and efficient combustion this way that translates into decreased consumption, emissions and less frequent cleaning.

Thanks to Active plus, it is possible to control and communicate with the stove, even by way of Smartphone and tablet. Since it is possible to manage more evolved gear motors (with continuous operation), and the new pellet stoves equipped with active plus are more silent.

• Room Therm.2

The stove heat request may take place from any part of the room probe or from the “Termostato Amb 2” (Room thermostat 2) installed in a room that is different from the one where the stove is positioned and is connected to terminals 1 and 2 of the back terminal board.

Contact closing the terminal kicks off the heat request.

Notes: Installation of this thermostat is optional, the stove can also operate without it. Since the contact is N.O., the room probe is the only heat request command.

Possible active weekly programming does not act on Room Thermostat 2 but rather on the probe on board the stove.

50


• External probe

It makes it possible to work with system temperature adjustment. If installing an external probe on terminals 1 and 2 (NTC 10KOhm at

25°C b=3435) water temperature is automatically calculated by the electronics based on the external temperature according to the curves shown below.

The external probe must be installed on an external wall exposed towards North or North-West. If necessary, it is possible to correct the value read by the probe of + 5 -5°C.

• Boiler probe

To activate this option, connect a probe (NTC 10KOhm at 25°C b=3435) to points 1 and 2 of the back 9 pole terminal board.

The heat request occurs when the boiler probe reads a temperature that is 2°C below the one set by the accumulation temperature marked by a tap in the temperature menu.

In this configuration the aux output is configured as a potential free contact to control the 3-way valve (contact 7-8-9 of the back 9 pole terminal board)

• Boiler thermostat

To activate this option, connect a Normally Open (N.O.) contact thermostat to points 1 and 2 of the back 9 pole terminal board.

The heat request occurs when boiler thermostat closes the contact.

Even with this configuration the Aux output is configured as a potential free contact to control the 3-way valve (contact 7-8-9 of the back

9 pole terminal board).

• Puffer probe

To activate this option, connect a probe (NTC 10KOhm at 25°C b=3435) to points 1 and 2 of the back 9 pole terminal board.

The heat request occurs when the boiler probe reads a temperature that is 2°C below the one set by the accumulation temperature marked by a radiator in the temperature menu.

During the installation with puffer, stove operation is only and exclusively determined by the puffer probe and not by the room probe. The purpose of the room probe on the stove is only to control the heating system pump controlled by the potential free contact N.O.: (max 5 ampere, not suitable for brushless pumps with upper start-up current) on terminals 8-9.

Example of operation with Hydro Air On or Auto:

• if the puffer is satisfied but the room probe is not, with eco stop active the stove shuts off (continuing to disburse heat through the room fan up until shut-off)

• if the puffer is satisfied but the room probe is not, with eco stop deactivated, the stove remains on at minimum power. In this case hot water from the puffer is used through the pump to heat the front radiator

• if the puffer calls for heat and the room probe does not, the fan behaves based on “Hydro Air” and “Ventilatore” (Fan) settings.



• Puffer thermostat

To activate this option, connect a Normally Open (N.O.) contact thermostat to points 1 and 2 of the back 9 pole terminal board.

Even with this configuration the purpose of the room probe on the stove is only to control the heating system pump controlled by the potential free contact on terminals 7-8-9.

15 - SAFETY DEVICES AND ALARMS

SAFETY DEVICES

The product is fitted with the following safety devices

ACTIVE +

Besides adjusting the stove operation, it also guarantees that the pellet loading auger is blocked if unloading or there is significant back pressure.

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 stove.

WATER THERMOSTAT

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

WATER TEMPERATURE SENSOR

When the water reaches the stop temperature (85°C) the probe automatically instructs the boiler to carry out automatic "OFF Stand-by" shut-off.

ELECTRICAL SAFETY

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

SMOKE FAN

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

GEAR MOTOR

If the reduction motor stops, the stove will continue to run until the flame 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 stove returns to its previous operating state; if it is more, it executes a cooling/re-ignition cycle.

FAILED START-UP

If during ignition no flame develops, the stove will go into alarm condition.

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.

60


TAMPERING WITH THE SAFETY DEVICES IS PROHIBITED

If the stove is NOT used as described in this instruction booklet, the manufacturer refuses to accept any responsibility for damage to persons and property that may arise. The manufacturer furthermore refuses to accept responsibility for damage to persons and property arising from the failure to observe all the rules contained in the manual and in particular:

• All the necessary measures and/or precautions must be adopted when performing maintenance, cleaning and repairs.

• Do not tamper with the safety devices.

• Do not remove the safety devices.

• Connect the stove to an efficient smoke extraction system.

• First, check that the environment where it is to be installed is properly ventilated.

Only after eliminating the cause of the intervention of the safety system is it possible to re-ignite the stove and thus restore its automatic operation. This manual will help you understand which anomaly has occurred, and explain how to intervene according to the alarm message displayed on the stove.



ALARM ALERTS

If there is an operational anomaly, the stove enters the alarm phase displaying the problem that has taken place through a code, a brief description of the alarm type and an acoustic warning.

Exiting the alarm conditions

When the stove enters an alarm state, an automatic cooling/shut-off phase begins, at the end of which the cause of the alarm is displayed on the small panel.

Before resetting the alarm, follow the controls indicated in the previous table, and then press the RESET key for a few seconds (or remove power to the stove using the main ON/OFF switch on the back of the stove).

If the indicated actions do not resolve the problem, the alarm condition will occur once again with different timing based on the alarm type: in this case, contact technical assistance.



SHUT DOWN

If the shut down key is pressed or one of the following conditions occurs:

• power request ends (Power = 0) for Ecostop, Timer, Sleep

• an alarm condition occurs

• water overheating occurs the stove enters the shut down and thermal cooling phase that includes automatically executing the following phases:

• pellet loading stops

• the room fan maintains the set speed until it cools down

• the fumes extractor is activated at maximum speed and remains on for a fixed period of 5 minutes, at the end of which the stove off temperature is reached.

During the shut down phase the small panel displays the wording OFF (see screen) but if it is in shut down due to an alarm condition, the small panel displays the related code (See alarms table)

BLACKOUT WITH STOVE ON

If power is lost for less than 10" from stove start-up, it is repositioned in the phase where it was before the power failure.

If the loss of power exceeds 10", when the stove is powered once again, it goes back to the previous operational condition with the following procedure it

• carries out a cooling phase, during which the panel displays OFF BLACKOUT

• restarts the stove

If the stove is in ignition phase when the blackout occurs, it will not turn back on once the power is restored (there is a risk that residual pellets are present in the brazier) and the panel will display OFF BLACK-OUT.

If the ON key is pressed during the cooling phase, the stove stops executing the blackout restore state and it proceeds with ignition as requested by the command. In the same way, pressing OFF is interpreted as a shut off command.

16 - CLEANING AND MAINTENANCE

EXAMPLE OF A CLEAN BRAZIER EXAMPLE OF A DIRTY BRAZIER

ATTENTION!

All the cleaning operations of all parts must be performed with the product completely cold and the plug disconnected.

The product requires little maintenance if used with certified good quality pellets.

DAILY OR WEEKLY CLEANING PERFORMED BY THE USER

BEFORE EACH IGNITION

Clean the ash and any deposits in the brazier that could clog the air passage holes. If the pellets in the hopper run out, unburned pellets may accumulate in the brazier. Always empty the residue in the brazier before each start-up.

REMEMBER THAT ONLY A CORRECTLY POSITIONED AND CLEAN GRATE CAN GUARANTEE THE OPTIMAL LIGHTING AND

OPERATION OF YOUR PELLET STOVE.

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.

CHECKS TO BE PERFORMED EVERY 2/3 DAYS

Clean compartment around brazier to remove any ash, being careful of hot ash.

Only if the ash is completely cold, is it possible to use a vacuum cleaner to remove it. In this case, use a suitable vacuum cleaner to remove particles of a certain size. The quality of the pellets used and user experience will determine the required cleaning frequency.

However, it is recommended not to exceed 2 or 3 days.

CLEANING THE GLASS

It is recommended to clean the ceramic glass with a dry brush, or if it is very dirty, spray a little specific detergent and clean with a cloth.

ATTENTION!

Do not use abrasive products and do not spray the glass cleaning product on the painted parts and on the door gaskets (ceramic fibre cord).



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 “PULIZIA” (CLEANING) function – with the stove on press - menu (“E” key), select “IMPOSTAZIONI” (SETTINGS) using the “C” and “D” key and press OK (“E” key), scroll using the “C” and “D” keys and select “CICLO PULIZIA” (CLEANING CYCLE), confirm pressing “OK” (“E” key), activate the “ATTIVA CICLO DI PULIZIA” (ACTIVATE CLEANING CYCLE) function, confirm by pressing OK (“E” key).

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 provided hook ”A”, shake the rods located beneath the top firmly 5-6 times. This will remove any soot that has deposited on the exchanger's smoke ducts during normal stove operation.

• Deactivate the “CICLO PULIZIA” (CLEANING CYCLE) function – this function is deactivated by pressing the “DISATTIVA CICLO

PULIZIA” (DEACTIVATE CLEANING CYCLE).

• Clean the smoke conveyor compartment (fig. in following page) - The stove is equipped with a removable ash tray “ G ” which collects any accumulations of soot and ash.

• Once cleaning is finished reposition the top and the ash tray“ G ”.

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.

To avoid removing the entire cladding, block the two front profiles with two clamps “ 4 ”.

• Remove the four screws “ 5 ” and as a result remove the two plates of the turbulator rods “ 6 ”

• Loosen the two screws “ 7 ”, remove the two screws “ 8 ” and remove the entire fan block “ 9 ”

• Remove the exchanger “ 10 ”

• Loosen the two screws “ 11 ”, remove the two screws “ 12 ” and remove the exchanger support “ 13 ”

• Loosen the two screws “ 14 ” and remove the rods “ 15 ”

• Remove the two screws with shims “ 16 ” and the stove cover “ 17 ”

• Remove the turbulators “ 18 ”

At this point, using a rod or a brush for cleaning bottles, clean inside the pipe unit and the pipes, removing any ash deposits.

Check the cover seal “ 17 ” and replace it if necessary.

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

CLEANING THE 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 flue, contact a chimney sweep.

Check the seal of the ceramic fibre gaskets on the door of the stove. If necessary, order new replacement gaskets from the retailer or contact an authorised service centre to carry out the operation.

CAUTION:

The frequency with which the smoke outlet system is cleaned depends on the use of the boiler and the type of installation.

We recommend relying on an authorised service centre for end-of-season cleaning and maintenance, as they will carry out all of the previously mentioned work and inspect the stove components.

SHUTDOWN (end of season)

At the end of each season, before switching the product off, it is recommended to remove all the pellets from the hopper with a vacuum cleaner with a long pipe.

When not in use the appliance must be disconnected from the mains power supply. It is recommended to remove the power cable for additional safety, especially in the presence of children.

The service fuse may have to be replaced if the control panel display does not switch on when the product is switched on again by pressing the main switch on its side.

There is a fuse compartment on the back of the product, under the power socket. After having disconnected the plug from the socket, use a screwdriver to open the cover of the fuse compartment and if necessary, replace them (3.15 A delayed).



CHECKING THE INTERNAL COMPONENTS

ATTENTION!

The internal electromechanical components must only be checked by qualified 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 internal components. The following is a summary of the checks and/or maintenance that are essential for the correct operation of the product.
