LEGEND Fig. 6 page 9

1 Room to ventilate 2 External air inlet

• The room must be endowed with an external air recycling for a good climate in your ambient.

• The air inow from outside to the inner occurs directly, through an opening on the external wall of the room (see Fig. 6 page 9).

• Bedrooms, garages, and store of ammable materials are excluded.

• The air inlet should have a total net surface of 80 sqcm2: the aforesaid surface is to widen if inside the room

there are other activated appliances (for example: electric ventilators for foul air suction, cooker hoods, other stoves, etc...) which depress the environment.

• At switched on appliance it is necessary to check that the pressure fall between the room and the outside does not exceed 4,0 Pa value: if necessary widen the air inlet (EN 13384).

• The air inlet must be realized at a height close to the oor with an external grid against birds. In such a way it cannot be obstructed by any object.

• In case of installation with sealed-chamber the air inlet is not necessary.

9.9 COMBUSTIBLE AIR INLET FOR SEALED-CHAMBER INSTALLATION

Check page 36 if the purchased stove has a sealed-chamber. If the stove is endowed with a sealed-chamber and you want also the whole installation with sealed chamber, please read the following instructions:

• It is necessary to extract the air for combustion directly from outside.

• Use a tube with minimum Ø60 mm and maximum 2 meters lenght; to connect see the back of the stove.

• French standards require installation in double-walled ues (concentric system). The combustion air is drawn

from the cavity.

• During installation step is necessary to verify the minimum distances required for the combustible air inlet as (for example) an open door or window causes a vortex which could remove the combustible air necessary to the stove (see the underlying scheme).

• On the external wall it is necessary to install a curve at 90° to protect the combustible air inow from wind effects: turn the curve inlet downwards, see Fig. 7 page 10.

• Endow the curve with an external shield grid against birds in such a way that it cannot be obstructed by any object.

Check with your local authorities if exists any restrictive regulation regarding the combustible air inlet: if present, they must be applied

In some countries and/or regions the installation with sealed-chamber is obligatory: in case of doubt, please follow the most restrictive regulations.

• Pellets features are: dimension Ø6-7mm (D06 Class), maximum lenght 40 mm, caloric value 5kWh/kg, humidity

≤ 10%, ash remains ≤ 0,7%, they must be correctly pressed and not much mealy, without sizing agents, resins and other additives (it is advisable to use pellets in compliance with the regulation EN14961-2 type ENplus-A1

• Not adequate pellets cause a bad combustion, a frequent burning pot obstruction and exhaust conduits

obstruction. Further it decreases the caloric value, soils the glass and increases consumptions and ash and unburnt granules quantity.

Humid pellets cause a bad combustion and running, so please assure you that they are stored in dry places and far at least one meter from the stove and/or any other source of heat.

• It is advisable to try different type of pellets available on the market and to choose that which gives the best performance.

• The use of bad quality pellets can damage the stove so that the warranty and manufacturer liability fall.

• On all our product are used high-quality materials such as stainless-steel, steel, cast iron, etc... These materials,

before being sold on the market, are tested in laboratory, but despite this on the components which enable the pellets ow (auger) there could exist minimum differences in the material used, in roughness and porosity, which could generate usual variations in fuel transportation (pellets), causing a ame raising or drapping with a possible switching off at lower powers.

• Depending on the type of pellets it could be necessary a parameters adjustment, please contact an Authorized Assistance Service.

INSTALLATION

11.1 INTRODUCTION

• The assembly position must be chosen depending on environment, outlet, chimney ue.

• Check with local authorities if there are any restrictive regulations which regard the combustible air inlet,

room ventilation, fume exhaust system together with chimney ue and chimney pot.

• Check if there is the combustible air inlet.

• Check the probable presence of other stoves or appliances which could depress the room.

• Check at switched on stove if there is the presence of CO in the room.

• Check if the chimney has the necessary draught.

• Check if during the fume passage all has been executed in safety (probable fume losses and distances from

ammable materials, etc.…).

• The installation of the appliance must enable an easy access for appliance, fume exhaust pipes and chimney ue cleaning.

12.6 START UP

We remind you that the rst ignition must be carried out by a specialized and authorixed technician who will check that all is installed in compliance with current regulations and checks the efciency.

Page 22

EASY - SWEET

• If inside the combustion chamber there are booklets, manuals, etc..., remove them.

• Check if the door is correctly closed.

• Check if the stove is correctly inserted in the electric socket.

• Before switching the stove on, assure you the burning pot is clean.

• To start the stove, keep the P1 button pressed until the ON sign and a ashing ame to its side appear. The

ignition resistance pre-heating starts. After some seconds the feed screw loads pellets and the resistance preheating continues. When the temperature is high enough (after about 5-8 minutes), ignition is considered to be completed.

• Once the ignition step is complete, the stove moves into operating mode and shows the selected heat

output, the ambient temperature and the big ame (see Fig. 30 page 22).

• If the ambient temperature value exceeds the limit set on the button panel in the temperature set, the heat

output is brought to its lowest value and the small ame is shown (see Fig. 31 page 22). When the ambient temperature decreases below the set temperature, the stove goes back to the set output.

Fig. 30 - Big ame Fig. 31 - Small ame

12.7 FAILED IGNITION

If pellets should not ignite, the lack of ignition will be signalled by the A01 "No Ignition" warning. If the ambient temperature is below 5°C, the resistance may not heat up enough to guarantee the pallet ignition. In this case, remove the unburned pellets from the burning pot and restart ignition.

• Too much pellets in the burning pot, or humid pellet, or sooty burning pot make ignition difcult and create dense white smoke which is harmful to health and can cause explosions on the combustion chamber. It is therefore necessary not to stand in front of the stove during ignition stage if dense white smoke is present.

If after some months the ame appears weak and/or orange colored or the glass tends to blackens and the burning pot to become encrusted, clean the stove, clean the fume conduit and the chimney ue.

12.8 SWITCH OFF (ON PANEL: OFF WITH FLASHING FLAME)

If the shutdown key is pressed or if there is an alarm signal, the boiler goes into the thermal shutdown phase which entails the automatic execution of the following stages:

• Pellet loading is stopped.

• The room fan continues to operate until the requested temperature is reached.

• The ue fan is set to its highest value, which it keeps until the requested temperature is reached, plus a

safety time of 10 additional minutes. After that, if the fume temperature has decreased below the switch off threshold, it stops, otherwise the cooling process goes on.

• If the stove has switched off normally, but owing to thermal inertia, the fume temperature goes over the threshold again, the switch off process is reactivated until the temperature decreases again.

12.9 POWER FAILURE

• After a black-out lower than 10 seconds, the stove turns back to the power which was settled.

• After a black-out of more than 10 seconds, the stove enters the during shutdown. Completed this phase, it

starts automatically up with the different phases.

12.10 ADJUSTMENTS MENU

To access the adjustments menu act as follows:

• Press the + - keys

• Scroll with the <> arrows and select “Set Room T.” or “Air Fan Speed” or "Fire"

• Press “menu” to access the selected option.

• Modify with the + - keys.

• Press “menu” to conrm and “esc” to exit.

Set Room T. - this function allows setting the desired temperature in the room where the stove is installed, starting from a minimum of 5°C up to a maximum of 35°C. When this condition is met, the stove reaches the minimum consumption values (ame and hot air fan speed at minimum values) and then goes back to the set values when the ambient temperature goes below the set threshold (see Fig. 32 page 23).

Page 23

EASY - SWEET

Fig. 32 - Display

Note: The full stop to the right of the ambient temperature shown in the control panel display (upper right) indicates the half degree (e.g. 23.° means 23.5°C).

Air Fan Speed - this function allows selecting the desired speed for the ambient fans from 1 to 5 or A. A means automatic, ventilation depends on power, recommended setting (see Fig. 33 page 23).

A power 1 fans are off.

Fig. 33 - Display

Fire - this function allows setting the ame power from a minimum of 1 to a maximum of 5. The power levels correspond to a different fuel consumption value: by setting 5 you can heat the room in less time, while by setting 1 you can keep the ambient temperature constant for a longer period. The ame set goes to the minimum value automatically when the set temperature value is reached. If only one notch appears, the stove has a ame power equal to 1. If 5 notches appear, the stove has a ame power equal to 5. If the notches ash, automatic cleaning is under way.

12.11 PROGRAMMED MODE (TIMER) - MAIN MENU

Setting the current day and time is essential for the proper operation of the timer.

There are six TIMER programmes, for each one the user can decide the start-up and shutdown time as well as the day of the week in which it is active. When one or more programmes are active, the panel alternately displays the boiler status and TIMER “n” whereby “n” is the number relating to the activated timer programmes, separated from each other with a dash Example:

• TIMER 1 Timer programme 1 active.

• TIMER 1-4 Timer programmes 1 and 4 active.

12.13 NOTES FOR TIMER OPERATION

• Start-up with the timer always takes place with the last temperature and ventilation settings (or with default 20°C and V3 settings in the event they have never been changed).

• Start-up time ranges from 00:00 a 23:50

• If the shutdown time is not already memorised, it proposes a start-up time in + 10 minutes.

• A timer programme switches the boiler off at 24:00 of one day and another programme switches it on at 00:00

of the next day: the boiler stays on.

• A programme proposes a start-up and shutdown in times included within another timer programme: if the boiler is already on, start will not have any effect, while OFF will switch it off.

• In the boiler on and timer active condition, press the OFF key and the boiler will switch off, it will switch on automatically at the next time set on the timer.

• In the boiler off and timer active condition, press the ON key and the boiler will switch on, it will switch off at the time set on the active timer.

12.14 AUTO ECO MODE (SEE SECTION F-G SETTINGS MENU PAGE 20)

To activate the “Auto-Eco” mode and adjust the time refer SETTINGS MENU page 20. The possibility to adjust the “Off Time Eco” comes from the need to ensure proper operation in the various rooms the boiler can be installed in and prevent continuous shutdowns and start-ups in the event the temperature is subject to sudden changes (air currents, poorly insulated rooms, etc.). The ECO switch off procedure is automatically activated when the power recall device is activated (Room probe +1°C or external thermostat with open contact, see Fig. 36 page 24). "Off Time Eco" time decrease starts (5 minutes by default, see Fig. 37 page 24, and can be modied from the "Settings" menu). During this phase the panel view is activated with the small ame and alternates chrono (if on) - active Eco.

Fig. 36 - Active eco 1 Fig. 37 - Active eco 2 Fig. 38 - Active eco 3

On the upper display the minutes for the Eco Stop countdown are shown. The ame goes to P1, where it remains until the set "Off Time Eco" time is over and, if conditions are still met, it switches to the switch-off process. The ECO switch-off countdown is reset if one of the devices resumes recalling power. When the switch-off procedure begins, the panel shows: Off - Active Eco - small ashing ame (see Fig. 38 page

24).

When the stove is switched off, the panel shows active OFF-ECO with the ame icon off. For an ECO switch on, the following conditions must be met simultaneously:

• Room probe -1°C or external thermostat with closed contact (for at least 20" to avoid false recalls).

Page 25

EASY - SWEET

• After 5 minutes from the beginning of the switch-off procedure.

12.15 SLEEP FUNCTION (MAIN MENU)

The sleep function is activated only when the boiler is switched on and allows to quickly set a time at which the product must switch off. To set the Sleep function act as follows:

• Enter MENU

• Scroll to SLEEP with the <> arrows

• Press Menu

• With the + - keys adjust the desired shutdown time.

The panel proposes a shutdown time of 10 minutes from the current time, adjustable with key 4 until the next day (I can therefore delay the shutdown for up to a maximum of 23 hours and 50 minutes).

Fig. 39 - Sleep

If the SLEEP function is active with the TIMER active the rst has priority over the latter, therefore the boiler will not switch off at the time set on the timer but instead by the time established by the sleep function, even if later than the time set on the timer.

12.16 PELLETS RECIPE (SEE SECTION J )

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

-30= 30% reduction with respect to the default setting.

-25= 25% reduction with respect to the default setting.

-20= 20% reduction with respect to the default setting.

-15 = 15% reduction with respect to the default setting.

-10= 10% reduction with respect to the default setting.

-5= 5% reduction with respect to the default setting.

0= No variation. +5= 5% increase with respect to the default setting. +10 = 10% increase with respect to the default setting. +15 = 15% increase with respect to the default setting.

12.17 SMOKE RPM VARIATION (SEE SECTION I SETTINGS MENU PAGE 20)

If the installation presents difculties for smoke evacuation (no draught or no pressure in the duct), the smoke and ash expulsion speed can be increased. 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 ashes. The values available are from -27% to +27% with variations of 3 points at a time. The variation in negative can be used in case the ame is too low.

12.18 CHIMNEY SWEEP FUNCTION (FOR MAINTENANCE TECHNICIANS ONLY) - SEE SECTION K

SETTINGS MENU PAGE 20

This function can be activated only when the boiler is on and with power output and heating operation power with parameters P5, with fan (if present) in V5. Any loading/smoke ventilation percentage corrections must be taken into account. This status lasts 20 minutes, the countdown is displayed on the panel. At any time the technician can interrupt this stage by quickly pressing the on/off key.

12.19 STOVE CALIBRATION AND DEPRESSION MEASUREMENT

This stove has a pickup point positioned on the tank in order to measure the depression of the combustion chamber and verify its proper operation. To do this, proceed as follows:

• Unscrew the nut at the back of the stove (see Fig. 40 page 26).

• Connect a digital pressure switch with a tube to detect the depression (see Fig. 41 page 26).

• Load the feed screw via appropriate function.

• Start the stove and set "Fire" at power 1 (the start of this stove lasts from 8 to 10 minutes to ensure minimum

draught).

• Compare the read values with those on the table.

• Change power every 10 minutes and wait for it to stabilise.

Page 28

EASY - SWEET

- clogged exhaust

- Signicant negative (wind)

- clogged fume passages

- open pellet loading tank

- open re door or worn/broken gaskets.

13.3 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.

13.4 CONTACT THERMOSTAT IN THE FUEL HOPPER

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

13.5 ELECTRICAL SAFETY

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

13.6 SMOKE FAN

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

13.7 GEAR MOTOR

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

13.8 TEMPORARY POWER CUT

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

13.9 FAILED START-UP

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

13.10 BLACKOUT WITH THE BOILER ON

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

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

• In the event of a power cut that lasts over 10” with the boiler on or in the start-up stage, when the boiler is

powered again it goes back to the previous operating condition with the following procedure:

1) It performs a cooling phase to the maximum.

2) Performs a new ignition.

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

13.11 ALARM ALERTS

Whenever an operating condition other than that designed for the regular operation of the boiler occurs, there is an alarm condition. The control panel gives information on the reason of the alarm in progress.

PANEL ALERT TYPE OF PROBLEM SOLUTION

A01 The re does not ignite.

Check whether the brazier is clean / level of pellets in the hopper.

Check pellet level in the tank.

Check that the burning pot is correctly positioned in its case and does not contain deposits or unburned material.

Check that the pellet cover and the re door are correctly closed.

13.12 ALARM RESET

To reset the alarm you must keep the 1 (ESC) button pressed for some time. The stove performs a check to determine whether the warning cause is still present. If this is the case, the warning will be shown again, otherwise the stove will switch to the OFF position. If the warning is still present, contact a service centre.

MAINTEINANCE

14.1 INTRODUCTION

For a long working life of the stove, have a periodic cleaning of the stove as described in the following paragrafs.

• Fume outlet pipes (fume conduit + chimney ue + chimney pot) must always be cleaned, scrubbed and checked by an authorized technician in compliance with local regulations, with the instructions of the manufacturer and those of your insurance company.

• If there are no local regulations and no instruction from your insurance company, it is necessary to have your fume pipe, chimney ue and chimney pot cleaned at least once a year.

• It is also necessary to have the combustion chamber, motors and fans cleaned and to have the gaskets and the electronical elements checked at least once a year.

All these operations must be planned in time with your Autorized Technical Assistance Service.

• After a long ineffective time, before turning on the stove check if there are obstructions in the fume exhaust.

• If the stove had been using continuously and intensely, the whole system (chimney included), must be

cleaned and checked more frequently.

• In case of replacement of damaged pieces please ask for the original spare part at the Autorized Retailer.

14.2 BURNING POT AND ASH TRAY CLEANING

The burning pot and ash tray cleaning must be executed at least every 2 days.

• Open the door.

Page 30

EASY - SWEET

Fig. 47 - Burning pot extraction Fig. 48 - Ash tray extraction Fig. 49 - Burning pot cleaning

• Extract the burning pot (see Fig. 47 page 30) from its seat and empty it from the ash.

• Extract the ash tray (see Fig. 48 page 30) and empty it from the ash.

• If necessary clean with a pointed object the holes obstructed by encrustations (see Fig. 49 page 30).

Fig. 50 - Burning pot box cleaning Fig. 51 - Cleaning with a brush

• Clean and drain away the burning pot box and ash tray box from ash which has accumulated in its inner (see Fig. 50 page 30).

• Clean also the hole for pellet drop with a brush (see Fig. 51 page 30).

• The ash remains must be poured in a metal container with a sealed lid and this container must never get in

touch with combustible materials (for example put on a wooden oor), as the inner ash keeps the embers ring for a long time.

• Only when the embers are off the ash coul be poured in the organic waste.

• Pay attention if the ame becomes red colured, if it is weak or if black smoke creates in the inner: in this case

the burning pot is encrusted and needs to be cleaned. If it is broken, it must be replaced.

14.3 HOPPER AND AUGER CLEANING

Per each pellets supply, check the probable presence of meal, sawdust and other remanins on the hopper bottom. If present, they must be removed with the aid of a vacuum cleaner (see Fig. 52 page 30).

Fig. 52 - Hopper and auger cleaning

Page 31

EASY - SWEET

The hand rejector grid must not ever be removed fron its housing. Clean the hopper bottom and the visible part of the auger exclusively as shown in the picture (see Fig. 52 page 30).

14.4 FUME CHAMBER CLEANING

Every 4/8 weeks the fume chamber cleaning must be executed.

For the Sweet model: you need to remove the frame (see SWEET SIDE PANEL DISASSEMBLY page 17).

• Remove the right deector (see Fig. 58 page 32).

• Clean with a pipe cleaner and suction any ash accumulated inside.

• Put everything back together.

14.6 FUME CONDUIT CLEANING

The exhaust system must be cleaned every month.

Fig. 59 - Fume conduit cleaning

• Remove the inspection lid of the T-union (see Fig. 59 page 32).

• Extract the ash which has accumulated in the inner.

• After cleaning repeat the operation in reverse order, checking the condition and efciency of the gasket,

and if necessary replace it.

It is important to sealed the cap othrwise noxiuous fumes will propagate among the room.

14.7 HOW TO CLEAN THE ROOM FAN (IF THERE IS ONE)

Clean every the year the room fan from ash or dust which can cause a blade unbalance and a greater noise.

• Remove the sides.

• Remove dust build-up using a brush or a vacuum cleaner (see Fig. 60 page 33).

14.8 FUME PIPES ANNUAL CLEANING

Clean once a week from soot with brushes. The cleaning operation must be executed by a specialized stove-repairer who will provide for the cleaning of fume pipe, chimney ue and chimney pot. He will also check their eciency and will release a written declaration of the safety of the appliance. This operation must be executed at least once a year.

14.9 GENERAL CLEANING

For cleaning external and inner parts of the stove do not use steel wools, muriatic acid or other corrosive and abrasive materials.

14.10 CLEANING OF PAINTED METAL PANELS

To clean painted metal panels use a soft cloth. Do not use degreasant agents like alcool, diluents, acetone, gasoline because these could irremediably damage the varnish.

14.11 GASKET REPLACEMENT

In case of deterioration of re door, hopper or fume chamber gaskets, it is necessary to replace them by an autorized technician in order to guarantee the good running of the stove.

Use exclusively original spare parts.

14.12 GLASS CLEANING

The glass-ceramic of the re door is able to stand till 700°C but not to thermal shocks. The probable cleaning with usual sale product for glass cleaning must be effected at cool glass in order to avoid explosions.
