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 offers different 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 calorific 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 certifications 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 certifications include, for example, ENPlus, DINplus, Ö-Norm M7135, and in
particular, guarantee the following characteristics:
•
•
•
•
•
•
•
calorific 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 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 render the guarantee and product liability invalid.

2-INSTALLATION INSTRUCTIONS
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 to check 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 distances from flammable or heat-sensitive objects (sofas, furniture,
wood panelling, etc..) as specified below. The front distance from flammable materials must be at least as set out in the product’s technical
data table.
If particularly delicate objects are present, such as furniture, curtains or sofas, increase the stove clearance accordingly.
If the 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.

2-INSTALLATION INSTRUCTIONS
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 efficient and correct smoke flue but is under no circumstances to substitute the
regulations 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 intake of air for combustion, the smoke extraction system, the flue 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 insufficiently sized flue in
violation of regulations 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, 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 in cement must be suitably lined. In both solutions there must be an inspection cap (AT) and/or inspection hatch (AP)
- FIG.1.
It is prohibited to connect more than one wood/pellet or any other type of appliance (vent cowling...) to the same flue.
min.3,5 metri
The stove must be connected to a flue pipe or an internal or external vertical duct conforming to EN 1856-1-2 to suit the
appliance and types of fuels to be burnt – refer to detailed guidance in sections 2, 3 and 4 in ADJ (ONLY FOR UK).

TECHNICAL CHARACTERISTICS
Have the 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.

DIMENSIONING
The drop in pressure (draft) of a flue 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 flue can be circular (best variation), square or rectangular (the ratio between the interior sides must be
≤1.5) with the sides joined with a minimum radius of 20 mm. The dimension of the cross-section must be minimum Ø100mm.
The cross-sections/lengths of the chimneys shown in the technical data tables are indications for correct installation. Any alternative
configurations must be correctly dimensioned in accordance with the general method of calculation of UNI EN13384-1 or other proven
efficiency methods.
Below is a list of some flues available on the market:
Steel chimney AISI 316 with
double chamber insulated with
ceramic fibre or equivalent
resistant up to 400°C.
Refractory chimney with Traditional square-section clay
double insulated chamber and chimney with insulating empty
external lightweight concrete inserts.
cladding with cellular material
such as clay.
Avoid products with an internal
rectangular section where the
larger side is 1.5 times the
smaller side (e.g. 20x40 or
15x30).

2-INSTALLATION INSTRUCTIONS
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 functioning of the heater and, if large build-ups accumulate, can catch fire. The flue and chimney must be cleaned and
checked by a skilled chimney sweep at least once a year. Once the check/maintenance has been performed, request a signed report stating
that the system is safe.
Failure to clean the system jeopardises its safety.
CHIMNEY
The chimney is a crucial element for the heating appliance to work properly: we recommend a wind proof chimney (A), see Figure 7.
The area of the opening for smoke extraction must be at least double the cross-section of the smoke duct/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 zone created by the
shape of the roof or any obstacles near
the outlet (see Figures 2-3-4-5-6).

2-INSTALLATION INSTRUCTIONS
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 cause depression
in the room. A check must be carried out to ensure that, with all equipment on, the pressure drop between the room and the outside does
not exceed a value of 4 Pa. (also for Oyster appliances if combustion air has not been suitably ducted outside). If necessary increase the
intake section of the air inlet, which must be made at 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.
In order to fully enhance the sealed features and heating performance of this Oyster appliance, and thus to avoid fitting a free air intake

4-INSTALLATION AND ASSEMBLY
The stove body or unit must always be kept in a vertical position when handled and moved by using carts only. Pay particular attention to
the door and its glass, protecting them from mechanical knocks that would compromise their integrity. Always handle the product with
care. If possible, unpack the stove near the chosen place of installation.
The packaging materials are neither toxic nor harmful, and therefore no particular disposal measures are required. Therefore, the end user
is responsible for product storage, disposal or possible recycling in compliance with the relative applicable laws.
Do not store the stove unit or its cladding without their packaging.
Position the stove without its cladding and connect it to the flue pipe. Use the four adjustable feet (J) to get the stove correctly levelled so
that the smoke outlet (S) is lined up with the connecting pipe (H). Once the connection operations are complete, assemble the cladding
(ceramics or steel sides).
If the stove needs to be connected to a discharge pipe which goes through the rear wall (to then connect to the flue), take utmost care
not to force the joint.
If the stove smoke outlet is forced or used improperly to lift it or position it, the operation of the stove can be
damaged irreparably.

SYSTEM CONNECTIONS
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 gate valves 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 connected too tightly to the system, and to allow slight movements.
The pressure discharge valve (C) must always be connected to a water drain pipe. The pipe must be adequate to
support the water’s high temperature and pressure.

SYSTEM FILLING
To fill the system, the stove can be equipped with an end piece (optional) with a check valve (D), for manual filling of the heating system
(if the optional 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 allow the valve to vent, it is recommended to loosen the grey cap by one turn and leave the red cap locked (see figure). The filling
pressure of the system WHEN COLD must be 1 bar. If during operation the system pressure drops (due to evaporation of gases dissolved
in the water) to values lower than the minimum ones indicated above, the user must use the filling tap to bring the pressure back up to
its initial 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 filling operation, always close the tap.

DOMESTIC HOT WATER PRODUCTION KIT (Primula/Orchidea stoves only)
The PRIMULA and ORCHIDEA stoves are equipped with a complete kit for the production of domestic water made up of:
• Plate heat exchanger
• A 3-way diverter valve
• Flow switch
• Pipes and fittings for connection
The kit comes preassembled by the manufacturer and it is designed to heat domestic water directly from the home water supply system.
When hot water is required and the tap is turned, the internal water flow switch will send a signal to the diverter valve to channel the hot
water contained in the boiler to the plate heat exchanger. The temperature of the domestic water highly depends on the temperature of
the water inside the heating system. This can be calculated to a good degree of accuracy by taking 10°-15°C away from the value shown
on the stove control panel (which is the temperature of the water in the boiler).
If hot domestic water is needed while the stove is ‘Switch-Off’ or in ‘ECOSTOP off’ mode, the stove will automatically and immediately
begin the start-up process to heat the water inside the boiler, and then the domestic hot water.
To ensure that the plate heat exchanger continues to work properly over time, one must be aware of the system water hardness to prevent
deposits from forming.
If the water in your home is very hard, you are advised to install a softening system upstream. You are advised to
service the plate exchanger annually to eliminate limescale and mineral salts sediments or to replace the heating
plates with new ones. These spare parts are supplied by the manufacturer.

5-PLUMBING CONNECTION
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 ASK YOUR PLUMBER FOR HIS 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 hydraulic shock absorbers to prevent water hammering 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 their extremely low thermal
conductivity.

6 - ELECTRICAL CONNECTIONS
GENERAL PRECAUTIONS
Electrical safety of the system is ensured only when it is properly connected to an efficient earthing system made in compliance with the
safety standards in force: gas, water or heating systems pipes are not suitable as earth connections.
One must check this essential safety requirement; if in doubt, request an accurate inspection of the electrical system to be carried out by
qualified personnel, because the boiler manufacturer is not responsible for any damage caused by failure to earth the system.
Have professionally qualified personnel check the electrical system is suitable for the maximum power absorbed by the heating system,
ensuring in particular that the diameter of cables is appropriate for the power absorbed by the loads.
The use of any component that is powered by electricity entails compliance with some basic rules such as:
• do not touch the appliance with wet and/or damp body parts and/or bare feet;
• do not pull the electric cables;
• do not leave the appliance exposed to weathering (rain, sun, etc.);
• do not allow the appliance to be used by children or inexperienced persons.
230V electrical power supply connection
Installation of the boiler accessory electrical components requires electrical connection to a 230 V – 50 Hz mains: This connection must
be state of the art according to the CEI standards in force.
Hazard!
Electrical installation must be carried out by a qualified technician only.
Before performing connections or any operation on the electrical parts, always disconnect the power supply and
make sure it cannot be accidentally reconnected.
Please note that the boiler electrical power line must be fitted with a bipolar switch with a contact gap greater than
3 mm, easy to access, in order to make any maintenance operations quick and safe.
The power cable must be replaced by authorised technical personnel. Failure to comply with the provisions listed above may compromise
the safety of the appliance.
ELECTRICAL CONNECTION
First connect the power cable to the side of the boiler and then to a wall socket.
The main switch at the side must only be activated to switch the boiler on; otherwise, it is advisable to keep it switched off.
It is recommended to disconnect the boiler power cable when the boiler is not used.

7 - INITIAL START-UP
GENERAL PRECAUTIONS
Remove all components that could burn from the brazier and glass (manual, various adhesive labels and any polystyrene).
Check that the brazier is positioned correctly and rests properly on the base.
After a long period of inactivity, remove any pellets left in the hopper (using a vacuum cleaner with a long pipe ), as they
could have absorbed moisture, thereby altering their original characteristics and no longer being suitable for combustion.
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 the brazier in time for the fire to be regularly ignited.
CANCEL THE FAILED START-UP ALARM STATUS BY PRESSING AND HOLDING KEY 1 (ESC). REMOVE THE PELLETS FROM THE
BRAZIER AND REPEAT START-UP.
If a flame does not ignite after a number of failed start-ups, even though the pellet supply is correct, make sure the brazier is set in place
correctly, which must be interlocked in its seat and free from any ash deposits. If no anomaly is found during this inspection, there
may be a problem with the product components or installation may not be correct.
REMOVE THE PELLETS FROM THE BRAZIER AND CONTACT AN AUTHORISED TECHNICIAN.
Avoid touching the boiler during the initial start-up, as the paint in this stage hardens; by touching the paint, the
steel surface may be exposed.
If necessary, touch up the paint with the spray can in the original colour (see the “Accessories for pellet boilers” section).
It is good practice to guarantee effective 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.
32
7 - INITIAL START-UP
Do not stand close to the product and air the room. The smoke and smell of paint will disappear after about an hour of operation, however,
remember they are not harmful in any case.
The boiler will be subject to expansion and contraction during the start-up and cooling phases, therefore slight creaking noises may be
heard.
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 is not immediately overheated and the temperature is increased gradually, initially using
low power. This will prevent damaging the ceramic or serpentine tiles, the welds and the steel structure.
DO NOT EXPECT HEATING EFFICIENCY IMMEDIATELY!!!
ATTENTION!
If during operation or initial ignition you encounter smoke spillage in to the room from the appliance
or the flue then please switch off the appliance, ventilate the room and contact the installation / service
engineer immediately.
OPENING/CLOSING THE DOOR
ATTENTION!
The door must be closed properly for the boiler to work correctly.
Use suitable protective clothing (such as gloves) to open the boiler door.
To open the door insert the supplied hook into the hole and lift the handle (as in the figure).
DOOR OPENING.
SETTINGS TO BE CARRIED OUT BEFORE THE INITIAL START-UP

7 - INITIAL START-UP
LOADING THE PELLETS
Fuel is loaded from the upper part of the stove by opening the door. Pour the pellets into the hopper.
To ease the procedure carry out the operation in two steps:
Pour half of the contents into the hopper and wait for the fuel to settle on the bottom.
Then complete the operation by pouring in the rest.
Do not pour the pellets up to the gasket because otherwise the door does not close properly, so the stove is not airtight
and the alarm is triggered. It is recommended to pour the pellets up to the lower limit indicated by the arrow (fig. below).
Never remove the protection grille from within the hopper. When loading prevent the pellet bag from coming into
contact with hot surfaces.
No other type of fuel other then pellets, in compliance with above-mentioned specifications, is to be inserted into
the hopper.
Store the back-up fuel at a suitable safety distance.
Do not pour the 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.). It is therefore
recommended to avoid coming into contact with these parts without adequate protective clothing.
PELLET LOADING AND GASKET
SAFETY
PROCEDURE TO FOLLOW IF ANY SMOKE SPILLAGE IS SEEN WITHIN THE ROOM OR THE APPLIANCE SUFFERS FROM AN EXPLOSIVE

10-OPERATION
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.
TIMER 1-2-3-4-5-6 Timer programmes all active.
EXAMPLE OF PROGRAMMING
With boiler on or off:
• access the MENU,
• scroll to TIMER with the <> arrows,
• press the “Menu” key
• the system proposes “P1” (Press the <> keys for the subsequent timers P2,P3, P4, P5, P6)
• to activate “P1” press the “Menu” key
• press + - and select “ON”
• confirm with the “Menu” key
At this point it will propose 00:00 as starting time, with key + - adjust the starting time and press the “menu” key to confirm.
The next step proposes a shutdown time of 10 minutes above that set for start-up: press the + key and adjust the shutdown time, confirm
with the “menu” key.
Subsequently the system proposes the days of the week in which to activate or deactivate the previously set timer. With the - or + key highlight
with the white background the day in which one wishes to activate the timer and confirm with the “menu” key. If no day of the week is
confirmed as active, in turn the timer programme will not appear active in the status screen.
Continue to program the following days or press “ESC” to exit. Repeat the procedure to program the other timers.

10-OPERATION
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.
AUTO ECO MODE (see section 8f and 8g)
To activate the “Auto Eco” mode and adjust the time refer to section 8 f and 8 g respectively.
The possibility to adjust the “ECO shutdown t” comes from the need to ensure proper operation in the various rooms the 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 shutdown procedure is activated automatically when all the power demand devices involved in the “system configuration” are
satisfied: room probe/external thermostat (configurations 1-2-3), flow switch (configuration 2), puffer thermostat/ntc (10 kΩ ß3435)
(configuration 4-5) or boiler thermostat/ntc (10 kΩ ß3435) (configuration 2-3). If all devices present are satisfied the “ECO shutdown t”
time decrease starts (by default 10 minutes, it can be changed within the “Settings menu”). During this stage the panel displays ON with a
small flame and alternately Chrono (of active) - Eco active. The minutes indicating the countdown for the Eco Stop are shown at the top of
the display. The flame goes into P1 and stays there until the programmed “Eco shutdown t” time has elapsed and if the conditions are still
satisfied, it goes into the shutdown stage. The ECO switch off countdown resets if one of the devices boosts power again.
When switch off starts the panel displays: Off - Eco Active - small flashing flame.
Once the boiler has reached the off condition, the panel displays OFF-ECO with the extinguished flame symbol.
To restart from ECO the following conditions must be satisfied simultaneously:
• Power demand
• After 5 minutes from the beginning of shutdown.
• TH2O < TSetH2O.
• If the domestic hot water (DHW) demands power - if envisaged - the first 5’ are ignored and the boiler restarts as needed.
NOTE: In configuration 4 - 5 the Auto Eco mode is enabled automatically. Even when one sets the “summer” function in configuration 2 - 3
it is enabled automatically. In the cases where it is designed to be active, it is not possible to deactivate the mode.
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).
If the SLEEP function is active with the TIMER active the first 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.

10-OPERATION
AUXILIARY BOILER (see section 8i)
One must install an additional module (optional) to enable start-up of an auxiliary boiler in the event the stove is switched off or in alarm
conditions. By default this function is deactivated, if needed activate it to access the settings menu.
PELLETS RECIPE (see section 8j)
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 flame is always high even at low powers and, vice versa if the flame is low one can decrease/increase the amount
of pellets in the brazier:
The available values are:
-3 = Decrease by 30% compared to factory settings.
-2 = Decrease by 20% compared to factory settings.
-1 = Decrease by 10% compared to factory settings.
0 = No variation.
1 = Increase by 5% compared to factory settings.
2 = Increase by 10% compared to factory settings.
3 = Increase by 15% compared to factory settings.
SMOKE RPM VARIATION (see section k)
If the installation presents difficulties 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 -30% to +50%
with variations of 10 percentage points at a time. The variation in negative can be used in case the flame is too low
PUMP ON T (experienced users only) - see section 8h
This menu item allows to adjust the pump activation temperature.
MAXIMUM POWER (experienced users only) - see section 8l
It allows to set the maximum flame limit at which the boiler can operate to reach the set temperature target.
CHIMNEY SWEEP FUNCTION (for maintenance technicians only) - see section 8n
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. During this interval the thermostat/puffer/room set point/H20 set point are not taken into account,
only the safety shutdown at 85°C remains active. At any time the technician can interrupt this stage by quickly pressing the on/off key.
54
10-OPERATION
SEASON FUNCTION (see section 8p)
In configurations 2 and 3, by enabling the “summer” function, the deviation of the 3-way valve to the heating system is inhibited in order
to prevent the radiators from heating up, therefore the flow is always directed towards the domestic hot water (DHW) - if envisaged.
By activating the “summer” option one automatically enables the auto-eco function (it cannot be deactivated). The room probe/external
thermostat are not taken into account.
FEED SCREW (see section 8d)
Allows to fill the pellets loading system. It can only be activated with the boiler switched off, it displays an 180” countdown after which
the feed screw stops automatically, as when exiting the menu.
COMPONENTS TEST (see section 8m)
It can only be carried out with the boiler switched off, it allows to select the components to be tested:
• Spark plug: it is turned on for a fixed time of 1 minute during which the panel displays the countdown seconds.
• Feed screw: it is powered for a fixed time of 1 minute during which the panel displays the countdown seconds.
• Extractor: it is activated at 2500 rpm for a fixed time of 1 minute during which the panel displays the countdown seconds.
• Exchanger: it allows to carry out the test in V5 for a fixed time of 1 minute during which the panel displays the countdown
seconds.
• Pump: it is activated for a fixed time of 10 seconds during which the panel displays the countdown.
• 3 way: the 3 way valve is activated for a fixed time of 1 minute during which the panel displays the countdown seconds.

back-pressure. (wind)
SMOKE TEMPERATURE PROBE
Detects the temperature of the smoke, thereby enabling start-up or stopping the product when the temperature drops below the preset
value.
CONTACT THERMOSTAT IN THE FUEL HOPPER
If the temperature exceeds the preset safety level, it immediately shuts down boiler operation.
CONTACT THERMOSTAT IN THE BOILER
If the temperature exceeds the preset safety level, it immediately shuts down boiler operation.
WATER TEMPERATURE PROBE
If the water temperature approaches the shutdown temperature (85°C) the probe makes the boiler perform the “OFF Stand-by” automatic
shutdown.
ELECTRICAL SAFETY
The product is protected against sudden current surges by a main fuse in the power supply panel on the rear part of the product. Other
fuses that protect the electronic boards are found on the latter.
SMOKE FAN
If the fan stops, the electronic board promptly shuts off the pellets supply and an alarm message is displayed.
GEAR MOTOR
If the gear motor stops, the boiler 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
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.
FAILED START-UP
If during ignition no flame develops, the boiler will go into alarm condition.
ANTIFREEZE FUNCTION
If the probe in the boiler detects a water temperature of less than 5°C, the circulation pump is automatically activated to prevent the

In the first case the alarm will still be displayed, in the second case it will go onto OFF.
If the alarm persists, contact the service centre.
58
11-SAFETY DEVICES AND ALARMS
NORMAL SHUTDOWN (on the 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:
• It stops pellets loading
• The room fan (if provided) maintains the set speed until the smoke T reaches 100°C, then it automatically sets itself at the minimum speed until it reaches the shutdown temperature
• The smoke fan sets itself at maximum speed and maintains it for a fixed time of 10 minutes, at the end of which if the smoke T has
fallen below the shutdown threshold it switches off permanently, otherwise it sets itself at the minimum speed until it reaches
such threshold before switching off.
• If the boiler was shutdown regularly but, due to thermal inertia the smoke temperature exceeds the threshold again, the shutdown
stage restarts at the minimum speed until the temperature goes down.
BLACKOUT WITH THE 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 cools down activating the smoke extractor at minimum power for 10’ and goes onto the next point;
2. It takes the boiler back to the operating condition before the blackout.
During stage 1 the panel displays ON BLACK OUT.
During stage 2 the panel displays Start-up.
If during stage 1 the 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.
BLACKOUT ABOVE 10” WITH BOILER IN SHUTDOWN STAGE
In the event there is a power cut that lasts MORE THAN 10” with the boiler in the shutdown stage, when the boiler is powered again it
restarts in shutdown mode even if the smoke temperature has fallen under 45°C in the meanwhile. This last stage can be skipped by
pressing key 1 (esc) (it goes into start-up) and by pressing it again (it recognises that the boiler is switched off).

12-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 certified to the required European standards. The ignition
system has been tested carefully to increase the lighting efficiency 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 final 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 insufficient maintenance, creating the conditions for a delayed ignition
causing a build up of unburnt gases
• Insufficient 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 flue pipe assembly which don’t comply with UK regulations and which don’t create the draught
required to effectively suck the smoke outside (e.g. too many bends in the flue).
• Partially blocked flue pipes, which indicates poor maintenance, reducing the draw on the chimney making ignition difficult.
• 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, first 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 affects the product repeatedly, despite a clean brazier and a usual fuel loading, we recommend that you immediately stop using the stove and contact a qualified 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 fulfilled, 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 off 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 flue gas outlet
could work not properly).
• Do not open the fire door: this would affect the regular smoke evacuation from the chimney.
• Simply switch off the stove by pressing the on/off 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 qualified technician to check the stove and chimney functionality

13-MAINTENANCE AND CLEANING
EXAMPLE OF A CLEAN BRAZIER
EXAMPLE OF A DIRTY BRAZIER
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 certified high quality pellets.
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 flow 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 specific detergent and clean with a cloth.
ATTENTION!
Do not use abrasive products and do not spray the glass spray cleaner on the painted parts or the door gaskets
(ceramic fibre cord).

13-MAINTENANCE AND CLEANING
CLEAN THE EXCHANGER AND THE UNDERGRATE SPACE EVERY 2/3 DAYS.
Cleaning the exchanger and the undergrate space is a simple operation but very important for always maintaining performance as
declared.
Therefore we recommend cleaning the internal exchanger every 2-3 days, performing these simple operations in sequence:
• Activate the “CLEANING” function – when the stove is switched of press - menu “3”, select“Settings”, with the <> arrows “2-4”
select “Cleaning”, confirm with “Menu”“3”, activate cleaning “ON” by pressing the +- keys “5-6”. This procedure activates the smoke
extraction fan on maximum power to expel the soot that is dislodged when the exchanger is cleaned.
• Clean the pipe unit – Using the hook provided, shake the rods located under the top (A in figure 10) vigorously 5-6 times. This
operation removes the soot that has deposited on the exchanger smoke ducts during normal stove operation.
• Clean the smoke conveyor compartment
PRIMULA/ORCHIDEA stoves (Figure 10)
– Primula/Orchidea stoves are fitted with a removable ash pan “C” designed to collect any soot and ash build-up.
•
GARDENIA/MARGHERITA stoves (Figure 10a)
– Open the door, insert the hook onto the rod of the scraper B (B in figure 10a), shake it vigorously 5-6 times along the entire length.
Remove the hook and reposition the rod B fully in its seat. This will help the fan expel any soot build-up which may have fallen during
the previous pipe unit cleaning process. (After shaking the rods “A”, always shake the scraper “B” too).
Disable the “CLEANING” function - this function is automatically disabled after two minutes. If one needs to stop this function
in advance press the “Esc” key.
If these cleaning operations are not performed every 2-3 days, the stove could go into alarm conditions due to ash
clogging after several hours of operation.

13-MAINTENANCE AND CLEANING
PERIODIC CLEANING PERFORMED BY A QUALIFIED TECHNICIAN
CLEANING THE HEAT EXCHANGER
Half-way through the winter season, but especially at the end of it, the compartment through which the exhaust smoke passes will need
to be cleaned. This cleaning process is mandatory in order to facilitate the general removal of all combustion residue, before it becomes
very difficult to remove it due to the humidity compacting it over time.
ATTENTION: For your safety, the frequency with which the exhaust smoke system is cleaned depends on the intensity
of use of the stove.
CLEANING THE EXCHANGER AND PIPE UNIT (PRIMULA/ORCHIDEA)
CLEANING THE UPPER COMPARTMENT
When the stove is cold, remove the top, remove the ceramics/sides, by loosening the relative fastening screws before removing the drivers
“B” and then remove the boiler cover “C” At this point, remove the four turbulators “D” and using a rigid rod or a bottle brush, clean the
internal pipe unit and the turbulators, removing all of the accumulated ash.
Check the cover gasket and replace it if necessary.
ATTENTION: It is advisable to carry out the cleaning of the upper exchanger at the end of the season and possibly by
an authorised technician in order to replace the gasket that is below plug “C”. (fig.11).
CLEANING THE LOWER COMPARTMENT
Remove the ash drawer “G”, empty it and using the nozzle of a vacuum cleaner remove any ash and soot that may have built up under the
drawer “G”. Remove the brazier “F” and clean it every 2/3 days.
Remove the drawer “E”, empty it and using the nozzle of a vacuum cleaner remove any ash that may have built up in the housing of the
drawer “E”.
ATTENTION: It is advisable to clean the lower compartment “E” once a week and in any case according to the fuel
consumption.

Remove the ash drawer “G”, empty it and using the nozzle of a vacuum cleaner remove any ash and soot that may have built up under the
drawer “G”. Remove the brazier “F” and clean it every 2/3 days.
Loosen the screws and remove the plug “E” and using the nozzle of a vacuum cleaner, remove any ash and soot that may have built up in
the exchanger “H”.
ATTENTION: It is advisable to clean the lower compartment “E” once a week and in any case according to the fuel
consumption.
Check the seal of the ceramic fibre gasket on the plug and replace it if necessary. Check the seal of the door gasket and replace it if
necessary.
At the end of the season one must clean the compartment under the brazier and the inside of the heat exchanger.
This general cleaning should be carried out at the end of the season in order to facilitate the general removal of all combustion residues,
without waiting too long, because with time and humidity these residues can become compacted.
CLEANING THE SMOKE DUCT AND GENERAL CHECKS:
Clean the smoke exhaust, especially around the T-fittings, curves and any horizontal sections. For information on cleaning
the flue, contact a chimney sweeper.
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 authorized service centre to carry out this task.
