9 - PRECAUTIONS BEFORE 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, check that the brazier is seated correctly: it must rest snugly against the slots and be clean of 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 necessary, touch up the paint with the aerosol spray in the original colour (see ''Accessories for pellet stoves'').

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.

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. To turn the stove on or o, press the button “B” on the control panel.

EXIT

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 ame has a tendency to shut-o, 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 plt 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. Eective and ecient combustion is independent from any type of connection to the ue 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, thus guaranteeing an eective and ecient combustion that is translated 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), the new pellet stoves equipped with active plus are more silent. This function is used to adjust combustion air if the ame is too high or too low. It can be activated from the SETTINGS menu, scroll using the “D” arrow key up to the “ACTIVE +” function, press OK using the “E” key, and,

• 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 dierent from the one where the stove is positioned and is connected to terminals 1 and 2 of the back terminal board. The stove's request for heat may be due to the closure of the contacts on the terminals and, simultaneously, to the stove's ambient probe (it is not a case of either or). If you only want the external thermostat, please see “Ambient inlet”. 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.

14 - MENU SETTINGS

• 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 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 by + 5 -5°C.

• Boiler probe

• 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 the boiler thermostat closes the contact. Even with this conguration, the Aux output is congured as a potential free contact to control the 3-way valve (contact 7-8-9 of the back 9-pole terminal board).

• Puer 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 installation with the puer, stove operation is only and exclusively determined by the puer 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.

SAFETY DEVICES

The product is tted with the following safety devices

ACTIVE +

Besides adjusting the stove operation, it also guarantees that the pellet loading feed screw is blocked if unloading is blocked or there is signicant 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 TANK

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-o.

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 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 stove 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 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 ame 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.

16 - SAFETY DEVICES AND ALARMS

When the stove enters an alarm state, an automatic cooling/shut-o 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 them 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 solve the problem, the alarm condition will occur once again with dierent 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 automatically includes the execution of 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 xed period of 5 minutes, at the end of which the stove o 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)

OFF

ECO

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 pellet is 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 o command.

17 - RECOMMENDATIONS FOR A SAFE USE

RECOMMENDATIONS FOR A SAFE USE

ONLY A SUITABLE INSTALLATION ACCORDING TO THE UK BUILDING REGULATIONS (ADJ) AND A PROPER MAINTAINANCE AND CLEANING OF THE PRODUCT CAN ASSURE YOU THE CORRECT FUNCTIONALITY AND A SAFE USE OF YOUR STOVE (ONLY FOR UK).

We wish to notify you that we have been made aware of incidents involving domestic heating pellet stoves resulting from the stoves having been incorrectly installed or inadequately maintained. In some cases the incident provoked an explosion that caused the glass door on the stoves to shatter. We would like to assure you that all of our products are very safe and are certied to the required European standards. The ignition system has been tested carefully to increase the lighting eciency and avoid any trouble even in the worst working condition. Moreover our structures are also provided with a safety device studied to discharge the eventual overpressure in combustion chamber, and avoid any damage to the product and consequent risk for the nal user. However, like any stove, our stoves need to be properly installed and maintained if they are to work safely. Our studies suggest that these explosions are mainly caused by a combination of some or all of the following factors:

• Clogged brazier holes or a deformed brazier, resulting from insucient maintenance, creating the conditions for a delayed ignition

causing a build up of unburnt gases

• Insucient combustion air due to the stove not having a big enough air inlet or not having an air inlet at all

• The use of smoke connections or ue pipe assembly which don’t comply with UK regulations and which don’t create the draught

required to eectively suck the smoke outside (e.g. too many bends in the ue).

• Partially blocked ue pipes, which indicates poor maintenance, reducing the draw on the chimney making ignition dicult.

• The chimney terminal not complying with our installation instructions and failing to prevent potentially dangerous down-draught.

This component becomes essential when the stove is installed in windy areas like coastal zones. Any of the above factors or any combination of them could generate unburnt gasses which in the worst cases could explosively ignite when there becomes enough oxygen present. To avoid this rare but not impossible inconvenient, rst of all the installation shall be done in compliance with UK building regulations and the suggestions described in this manual. Furthermore it’s absolutely important to respect the following simple rules:

• The brazier shall be always layed down in its proper position before any use of the product, removing completely the dirt if present

in the base plate

• Pellets must not be fed manually into the brazier, both before ignition and during the working condition.

• Eventual accumulated unburnt pellets in the burner after a failed ignitions must be removed before lighting

• If a failed ignition aects the product repeatedly, despite a clean brazier and a usual fuel loading, we recommend that you

immediately stop using the stove and contact a qualied technician to check the stove functionality. The respect of these suggestions is absolutely enough to guarantee a safe ignition and to avoid any inconvenient to the product. If the above precautions are not fullled, and the ignition shows an abnormal amount of pellet in the brazier and a consequent heavy generation of unburned gas in the combustion chamber, respect carefully the following suggestions:

• Do not switch o the electrical power from the stove for any reason: this would arrest the gas exhaust blower with a consequent

spread of smoke into the room.

• Precautionally open the windows to ventilate the installation room from eventual smoke outlet in ambient (the ue gas outlet could

work not properly).

• Do not open the re door: this would aect the regular smoke evacuation from the chimney.

• Simply switch o the stove by pressing the on/o button in the control panel (not the rear button of power supply!), and wait till the

smoke has been evacuated completely.

• Before any re-lighting attempt, clean completely the brazier and its air passages from any dirt and unburned pellet; put it in the

proper position removing the dirt eventually present in the base plate. If a repeated failed ignition happens, stop using the stove and

contact a qualied technician to check the stove and chimney functionality

18 - MAINTENANCE AND CLEANING

Example of a clean brazier

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

12).

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.

Example of a dirty brazier

DAILY OR WEEKLY CLEANING PERFORMED BY THE USER Brazier cleaning

Before ignition, always clean the “T” 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 EMPTY 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 “U” 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 GLASS

It is recommended to clean the ceramic glass with a dry brush, or if it is very dirty, spray a little specic 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 bre cord).

18 - 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 “PULIZIA” (CLEANING) function – with the stove on press - menu (“E” key), select “IMPOSTAZIONI” (SETTINGS) using

the “C” and “D” keys and press OK (“E” key), scroll using the “C” and “D” keys and select “CICLO PULIZIA” (CLEANING CYCLE), conrm

pressing “OK” (“E” key), activate the “ATTIVA CICLO DI PULIZIA” (ACTIVATE CLEANING CYCLE) function, conrm 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 rmly for 5-6 times. This will remove any

soot that has deposited in 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 (g. in following page) - The stove is equipped with a removable ash tray “G”, which

collects any accumulations of soot and ash.

• Once cleaning is nished, reposition the top and the ash tray“G”.

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

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 gasket of cover “G” and replace it if necessary (see gure on the previous page).

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

After cleaning the tube bundle open door “R”, extract the ash pan and empty it of any ash that has dropped while cleaning. Clean the turbulators and return all the pieces to their seats.

18 - 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 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.

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 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 each season, before switching the product o, it is recommended to remove all the pellets from the tank 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).

CLEANING THE CONTROL PANEL DISPLAY

ATTENTION!! THE PANEL DISPLAY IS VERY DELICATE, IT IS SUPPLIED WITH A PROTECTIVE FILM.

RECOMMENDATIONS FOR CLEANING:

Clean using a soft cotton cloth, which should be dry or slightly moist.

Do not use aggressive detergents or polyester materials. Do not use abrasive sponges or powder detergents nor solvents such as alcohol and petrol, since they may damage the surface of the device.

18 - MAINTENANCE AND CLEANING

REPLACEMENT OF OVERPRESSURE SILICON DAMPER FOR COMBUSTION CHAMBER

The overpressures sillicon damper “G” for combustion chamber (g. A) shall be replaced with a new one yearly (during the periodical maintainance) in order to keep the overpressure safety system ecient. For replacement use the following instructions

• remove the top

• remove the rst lateral ceramic covering / metal covering (in accordance with the model)

• unscrew the screw-washer-damper-spacer shown in g. A/C (operate same way on both sides) Install the new kit as follows:
