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 diameter varies
between 6 and 8 mm, with a standard length ranging from 5 to 30 mm. A good quality pellet has a density of between 600 and 750 or
more kg/metres cubed and a water content that accounts for 5 to 8% of its weight.
Pellets have technical advantages besides being an ecological fuel, as the wood residue is used completely, thereby achieving cleaner
combustion than that of fossil fuels.
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.
15 Kg BAGS OF FUEL
The poorer the quality of the fuel, the more often the internal parts of the brazier and combustion chamber must
be cleaned.
The main quality certifications for pellets currently available on the European market guarantee that the fuel complies with class A1/A2
according to EN14961-2. 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.
Water content: max 10% of the weight.
Percentage of ash: max 1.5% of the weight.
Diameter: 5 ÷ 6 mm.
Length: max 40 mm.
Content: 100% untreated wood without the addition of binding substances (max 5% bark).
Packaging: in sacks made from ecologically compatible or 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.

PRECAUTIONS REGARDING INSTALLATION
IMPORTANT!
Product installation and assembly must be carried out by qualified personnel.
The product must be installed in a suitable place that allows easy access for it to be opened regularly and for routine maintenance to be
performed.
The installation area must be:
• suitable to enable the appliance to operate correctly.
• Equipped with an adequate smoke extraction system.
• Equipped with adequate ventilation from outside.
• Equipped with 230V 50 Hz power supply with an EC compliant earthing system.
IMPORTANT!
The product must be connected to a chimney that expels the smoke at the highest point of the building.
The chimney must be of suitable dimensions, caulked, and fitted with a condensation collector for collecting the
water vapour that can form due to the high performance of the appliance and the consequently low temperatures
of the outgoing fumes.
The chimney must comply with regulations in force.
The holes of the external air inlet and the smoke outlet pipe must be drilled before positioning the product.
THE OPERATING AREA
The boiler must be installed indoors in an area well protected from atmospheric elements.
The surface on which it stands and/or support points must have sufficient load bearing capacity to support the total weight of the
appliance, its accessories and covers.
To ensure the appliance works well, we recommend installing the boiler detached from any walls or furniture, and with good air circulation
to allow effective ventilation for the appliance. The product should be located in an area that allows sufficient space for normal use and
maintenance operations.
The volume of the room should be no less than 15 m3.
It is essential that an adequate outdoor air intake is provided that supplies the air for combustion needed for the product to function
correctly.
These air inlets must be arranged so that it is impossible for them to be obstructed.
Protect the inlets with grilles, metal mesh, etc., without reducing the net cross-section.
Remember that the ventilation grilles always have the useful cross-section in cm2 indicated on one side. When
choosing the grille and size of the inlet, check that the useful cross-section of the grille is larger or equal to the
section required for product operation.
The flow of air between the outside and the room of installation may be direct, through an inlet in an external wall of the building; or
indirect, through the intake of air from rooms adjoining and connecting permanently with the room of installation. Adjoining areas may
not include sleeping areas, garages or general areas that present a fire hazard.
For air ducts, up to 3m increase the cross-section by approximately 5%, while for ducts that run for longer increase it by 15%.
IMPORTANT!
The air flow can also be drawn from an adjoining room to that of the room where the product is installed, provided
the air can flow freely through permanent openings to the outside; avoid connection to sleeping areas and rooms
that present a fire hazard in general.

2-INSTALLATION INSTRUCT
POSITIONING AND RESTRICTIONS
In the case of simultaneous installation with other heating appliances, provide appropriate air inlets for each one (according to the
instructions of each product).
Installation of the product is not permitted:
• in rooms where there are liquid fuel appliances with continuous or intermittent operation that draw the
combustion air from the room they are installed in;
• in rooms where there are B-type gas heating appliances, with or without domestic hot water production and
interconnecting rooms;
• in rooms in which the decrease in pressure during use, as measured between the pressure outside and the
pressure in the room, is greater than 4 Pa.
The product may not be installed in rooms used as sleeping areas, bathrooms, garages or in rooms that present a
fire hazard in general.
BOILER ROOM
Check that the room meets the requirements and provisions of the standards in force. There must also be a flow of at least enough air in
the room for normal combustion. Vents must be installed in the walls of the room that meet the following requirements:
• Increase the cross-section by at least 6 cm2 for each 1 kW (859.64kcal/h) The minimum cross-section of the opening must not,
however, measure less than 100 cm. The cross-section can be calculated using the following relations:
S = K * Q ≥ 100 cm2
Where “S” is in cm2, “Q” in kW, “K” = 6 cm2/kW
• The opening must be located at the base of an external wall, preferably opposite the one with the outlet for combusted gases.
Heat-sensitive or flammable objects cannot be stored near the product; keep such objects at a minimum distance of
80 cm from the outermost point of the product.

FOREWORD
This chapter on the Smoke Flue has been produced in reference to the prescriptions of European regulations (EN13384 - EN1443 - EN1856
- EN1457).
The chapter provides indications for installing an 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
min.3,5 metri
Have the efficiency of the flue checked by an authorised technician.
The flue or chimney is vital to the correct functioning of a forced draft solid fuel heating appliance, given that boilers with high performance
have cooler fumes with consequently weaker draft and the possible formation of condensation.
It is therefore essential that the flue meets all construction standards and is always maintained in perfect condition.
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 either case, ensure to include an inspection cap (AT) or inspection door (AP) and a
suitable device for collecting condensation - FIG.1.
It is prohibited to connect more than one wood/pellet or any other type of appliance (vent cowling...) to the same flue.

TECHNICAL CHARACTERISTICS
Flues serving a pellet/wood fuelled appliance must meet the following requirements:
• made of materials that are sufficiently resistant to mechanical stress, heat, the action of the products of combustion and their
vapours.
• made of materials that are impermeable to fumes, condensation, be thermally insulated and resistant to normal mechanical stress
over time
• go in a vertical direction and deviate no more than 45° from the vertical axis and be free of choke points
• be suited to the specific operating conditions of the product and have CE marking (EN1856-1, EN1443).
• Be of the correct size to suit the draft/smoke extraction requirements necessary for the product to work properly (EN13384-1)
• Be suitably caulked externally to avoid condensation and reduce the cooling of the smoke.
• Be at least category T400 (or greater if the appliance requires) and resistant to soot fires.
We recommend in particular to check on the data tags of the flue (in accordance with EN1856-1, EN1443) the safety distances that must
be respected in presence of passing combustible materials and the type of insulating material to be used. These indications must be
followed rigorously to avoid serious harm to personnel and surrounding infrastructure.
The chimney opening must be in the same room as the appliance, or at most in the adjoining room, and have a soot and condensation
collection chamber beneath the opening, and be accessible via a watertight metal hatch.
Smoke must be extracted through a single flue (see fig. 3) with insulated steel tubes (A) or though an existing flue that complies with
the intended use (B). A simple air shaft in cement must be suitably lined. In either case, ensure to include an inspection cap (AT) and/or
inspection door (AP) and a suitable device for collecting condensation - FIG.1.
It is prohibited to connect more than one wood/pellet or any other type of appliance (vent cowling...) to the same flue.

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 a minimum Ø150mm.
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 INSTRUCT
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 qualified chimney sweep at least once a year. Once the maintenance has been performed, request a written declaration that
the device is safe.
Failure to clean the system jeopardises the safety.
CHIMNEY
The chimney is a crucial element for the heating appliance to work properly: we recommend a wind proof chimney (A), see Figure 7.
The area of the opening for smoke extraction must be at least double the cross-section of the smoke duct/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).

Use smoke flues of 100mm diameter and silicon seals or similar seals that can resist the high operating temperatures of the appliance
(min. T200 class P1). The use of flexible metal tubes in fibre cement or aluminium is prohibited. For direction changes, we
always recommend the use of a T joint with an inspection cap allowing easy access for cleaning the tubes. Always ensure that the
inspection cap is replaced and hermetically sealed with the seal in tact after cleaning.
It is prohibited to connect more than one appliance to the same smoke duct, or the discharge from overhead cowling. It is prohibited to
extract the products of combustion directly through the wall, whether into indoor spaces or outdoors.
The smoke duct must be a minimum distance of 400 mm from flammable or heat-sensitive structures.

It is essential to make ventilation holes connecting to the exterior and in compliance with Standard UNI 10683, with the following
characteristics:
1.
2.
3.
They must be made at a height close to that of the floor;
They must be adequately protected by wire mesh or grille, provided it does not reduce the minimum passage section;
They must be positioned in such a way as not to be clogged.
Proper air flow can also be guaranteed by openings to an adjacent room, as long as it has direct ventilation and is
not an environment with danger of fire, such as storage rooms, garages or warehouses as regulated by Standard
UNI 10683.
It is good practice to install the boiler in rooms in which there are no leaking devices with respect to the room or appliances which may
cause depression in the room itself with respect to the external environment thus causing poor draught problems of the smoke evacuation
system (UNI 10683).

5-PLUMBING CONNECTION
PLUMBING CONNECTION
IMPORTANT:
The connections depend on the type of hydraulic kit installed and on the type of System Configuration.
IMPORTANT!
If installation of the product involves interaction with another, pre-existing system complete with heating
equipment (gas boiler, methane boiler, diesel boiler, etc.), contact qualified personnel, who subsequently will be
responsible for conformity of the system in compliance with the applicable law in force.
The Company declines all responsibility for damage to persons or things in the event of failed or incorrect operation,
if the aforementioned warnings are not complied with.
IMPORTANT!!!
FLUSH THE ENTIRE SYSTEM BEFORE CONNECTING THE BOILER IN ORDER TO REMOVE RESIDUES AND DEPOSITS.
Always install gate valves upstream from the boiler 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 boiler using hoses so that the boiler is not too strictly connected to the system, and to allow slight
movements.
HYDRAULIC KIT
The boilers must be connected to an optional hydraulic kit with ot without domestic water production.
CLEANING THE SYSTEM
Install suitable shutters to cut off the tubes from the heating system.
To protect the heating system from being damaged by corrosion, incrustation or smoke deposits, it is extremely important, before the
appliance is installed, that it be washed according to the UNI 8065 standard (water treatment of thermal systems for civil use) with
appropriate products.
As standard, RED supplied the product FERNOX PROTECTOR F1 with the product.
This provides long term protection against corrosion and calcium build-up for the heating appliance. It prevents the corrosion of the metal
parts of the appliance, i.e. the ferrous metals, copper and copper and aluminium alloys. It also reduces the noise produced by the boiler.
Refer to the instructions on the product. Cleaning should be performed by a qualified technician.
We also recommend the use of FERNOX CLEANER F3 and LEAK SEALER F4, available from our authorised distribution centres.
FERNOX F3 is a neutral product for rapid and efficient cleaning of heating appliances. It has been designed to eliminate residue, oily
deposits and incrustations from existing appliances of all ages. It can help restore the heating efficiency of the boiler and reduce the noise
it generates.
FERNOX F4 is intended to be used with all heating appliances to seal micro fractures that cause small and inaccessible leaks.
Attention: Failure to clean the heating system and to add a suitable inhibitor will void the warranty of the equipment
and other accessories such as for example pumps and valves.

5-PLUMBING CONNECTION
FILLING THE SYSTEM
Fill the system slowly to allow air bubbles to pass through the vent holes of the heating system. For closed circuit heating systems, the
filling pressure of the system at cold and the pre-inflation pressure of the expansion tank must be the same.
• In open vessel heating systems, direct contact between circulating liquid and air is allowed. During the heating season, the user
must check the circulating water level in the expansion tank regularly. The water level in the circulation system must be kept
constant. Practical experience shows that a regular check of the water level must be made every 14 days to maintain a relatively
constant level. When necessary, the water level must be topped up when the boiler has cooled to room temperature. This is to avoid
and damage being caused to the steel body of the boiler due to thermal stress.
• In systems with an open vessel, the water pressure in the boiler must not be less than 0.3 bar when the system is cool.
• The water used for filling the heating system must be decontaminated and not contain air.
Attention!
Do not mix heating water with incorrect concentrations of anti-freeze or anti-corrosion substances! This could
damage the gaskets and cause noise during operation.
The manufacturer denies any liability for harm caused to persons, animals or objects caused by failure to observe
these precautions.
After making all the hydraulic connections, pressure-test the seals by filling the boiler.
This must be done with care by doing the following:
• open the air vent valves of the radiators, boiler and system;
• gradually open the filling tap of the system, making sure that any automatic air vent valves in the system work correctly;
• close the vent valves of the radiators as soon as water comes out;
• use the pressure gauge inserted in the system to check that the pressure reaches a value of approximately 1 bar; for open vessel
systems, the water is topped up automatically through the vessel.
• close the filling tap of the system and then open the vent valves of the radiators again to purge any air;
• check the seal of all the connections;
•
•
after starting up the boiler for the first time and bringing the system up to temperature, stop the pumps and repeat the air purging
procedure;
leave the system to cool, and if necessary, restore the water pressure to 1 bar.
NOTE
In systems with a closed vessel, where possible, the water pressure in the heating system must not be lower than 1
bar when the system is at room temperature; if this is not the case, use the tap to fill the system.
This operation must be performed when the system is cool.
The pressure gauge on the system enables you to read the pressure in the circuit.
24
5-PLUMBING CONNECTION
To fill the system, the hydraulic kit (optional) is fitted with a tap, with a check valve, to load the heating system manually.
During this operation, any air in the system is released via the air valve located in the upper part of the boiler.
To ensure the valve vents, it is advisable to loosen the side cap (see figure)
The filling pressure of the system WHEN COLD must be 1 bar.
Upon completion of this filling operation, always close the tap.
AIR VALVE WITH SIDE CAP
LOOSENED BY 1 TURN
THERMOSTATIC DIVERTER VALVE (COMPULSORY)
The automatic thermostatic diverter valve is used in solid fuel boilers to prevent the return of cold water into the exchanger which would
cause condensation to form.
The prolonged formation of condensation irreparably damages the heat exchanger.
The lack of a device to prevent this invalidates the guarantee.
A higher return temperature reduces the formation of condensation of the fumes and extends the life of the boiler.
Valves available offer various calibrations. RED recommends the model (see accessories list) at 55°C.
Once the calibration temperature is reached, the valve opens providing hot water to the system.

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 back of the boiler and then to a wall socket.
The main switch placed on the back must only be activated to switch the boiler on; otherwise, it is advisable to keep it switched off.
It is recommended to disconnect the power cable when the boiler is not used.

7-INITIAL START-UP
BEFORE 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.
Technical Dept. - All rights reserved - Reproduction is prohibited
27
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 light 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!!!
OPENING/CLOSING THE INTERNAL DOOR
ATTENTION!
The door must be closed properly for the boiler to work correctly.
to open the internal door lift and pull the handle towards you. In the event one needs to open the door while the boiler is running one
must use suitable heat protection clothing (for example leather gloves).
OPENING THE INTERNAL DOOR.
SETTINGS TO BE CARRIED OUT BEFORE THE INITIAL START-UP
Once the power cable is connected in the rear part of the boiler, turn the switch, also placed at the rear, to position (I). To switch the boiler
on or off press key 1 on the control panel.

7-INITIAL START-UP
LOADING THE PELLETS
Pellets loading can be either manual or automatic. When empty the hopper can contain 100 litres i.e. roughly 70 kg of pellets.
Manual Loading:
• Open the upper door of the boiler directly and pour in the pellets.
Automatic Loading (to be combined with the remote 100/200 or 400 kg hopper - optional - see accessories):
• Remove the round plate from the door, cut the insulation and insert the hopper pipe. Subsequently load from the optional hopper.
Never remove the protective grille from inside the hopper. When loading pellets, prevent the bag from coming into
contact with hot surfaces.

8-MENU ITEMS AND 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.

•
•
•
•
•
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.
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.

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 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.

8-MENU ITEMS AND OPERATION
i - Auxiliary boiler
One must install an additional module (optional) to enable start-up of an auxiliary boiler in the event the boiler is switched off or in alarm
conditions. By default this function is deactivated, if needed activate it to access the settings menu.
l - Pellet Recipe
One must install an additional module (optional) to enable start-up of an auxiliary boiler in the event the boiler is switched off or in
alarm conditions. By default this function is deactivated, if needed activate it to access the settings menu. This function is for adapting the
boiler 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.
To change the recipe act as follows:
• Press the “menu” button.
• Scroll to “Settings” using the arrows
• Press “menu” to confirm.
• Scroll to “Pellet recipe” using the arrows.
• Press “menu” to confirm.

• Press “menu” to confirm and “esc” to exit
m - Smoke rpm % ventilation
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

9-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).

9-SAFETY DEVICES AND ALARMS
Safety thermostat - Alarm A03
This type of alarm occurs when the water temperature in the boiler exceeds 95°C.
The boilers contain a safety thermostat that prevents the water in the boiler from boiling.
The safety thermostat in the boilers must be reset manually. This is done by pressing the small button between the two sockets (see
below). Problems like this can happen if there is no water circulation because the pump is blocked, if all the valves are closed or if there
is no electricity.
CAUTION:
All operations must only be carried out when the boiler is switched off and the plug disconnected.
If the problem persists, contact a service centre.
To reset the safety thermostat in the case of alarm A03 proceed as follows:
• Switch the boiler off
• Disconnect the power supply
• Wait for the boiler to cool down
• Access the safety thermostat by opening the door to the boiler, removing the two screws and the plate (see figure below). You can
access the thermostat from the hole.
• Reset the thermostat by pressing the button between the two sockets until it clicks (if the button cannot be pressed, the boiler
temperature may still be too high or the thermostat may be damaged)
• set the plate back into position
• power the stove once again,
• Cancel the alarm (if the alarm persists, contact the service centre).
Reset the alarm by pressing key 1 (ESC) for a few seconds. The boiler checks whether the cause of the alarm is ongoing. In the first case,
the alarm continues to be displayed (contact the service centre) and in the second case it goes OFF.

DAILY OR WEEKLY CLEANING PERFORMED BY THE USER
BEFORE EACH START-UP
Using a suitable tool clean brazier “G” from ash and any incrustation which could obstruct the air passage holes. If the pellets in the hopper
finish, unburned pellets may accumulate in the brazier. Always empty the residue in the brazier before starting-up.
REMEMBER THAT ONLY A CORRECTLY POSITIONED AND CLEAN BRAZIER CAN GUARANTEE START-UP AND OPTIMAL
OPERATION OF YOUR PELLET BOILER.
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 you use good quality pellets, you will normally only need to use a paintbrush to restore the perfect operating condition of the
component. For tough incrustations, use the steel tool provided with the boiler.
CHECKS TO BE PERFORMED EVERY 2/3 DAYS
Clean the compartment around the brazier from ash paying attention to hot ashes.
Only if the ash is completely cold can a vacuum cleaner be used to remove it. Use a drum-type vacuum cleaner that is suitable for
picking up particles of a certain size. Experience and the quality of the pellets will determine the cleaning frequency required.
However, it is recommended not to exceed 2 or 3 days.

10-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 boiler is switched of press - menu, select“Settings”, with the <> arrows select
“Cleaning”, confirm with “Menu”, activate cleaning “ON” by pressing the +- keys. 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 cold handle supplied shake the rods placed under the cover vigorously 5-6 times. This will remove
any soot that has deposited on the exchanger smoke ducts during normal boiler operation.
• 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.
• Clean the smoke conveyor compartment (fig.2) - The boiler is fitted with a removable ash pan designed to collect any soot and
ash build-up.
• Once cleaning is complete close the cover and ash pan.
If such cleaning is not done every 2-3 days the boiler could go into alarm caused by ash clogging after several hours
of operation.

When the boiler is cold lift front cover “H”, remove screws “O” to the right and left and remove cover “A”. Then remove the the fixing screws
from drivers “V” and remove boiler cover “B”.
At this point, remove the four turbulators “C” 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 also replace the gasket located below plug “B”.
CLEANING THE LOWER COMPARTMENT
Remove ash pan “D” and empty it.
Lower lever “E” and extract drawer “F”. Remove the ash from the drawer and if needed use a vacuum cleaner to remove any other ash or
soot that has built-up under the drawer. Remove brazier “G” and clean it every 2/3 days. Check the seal of the ceramic fibre gasket on the
plug and replace it if necessary.
52
10-MAINTENANCE AND CLEANING
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 FAN COMPARTMENT
Remove the four screws that keep the plug fastened on the rear part of the boiler and remove any ash deposited on the smoke fan with
a vacuum cleaner.
Check the seal of the ceramic fibre gasket on the plug and replace it if necessary.
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 tightness of the ceramic fibre gaskets on the boiler door. If necessary, order new replacement gaskets from the retailer or contact
an authorized service centre to carry out this task.
ATTENTION:
The frequency with which the smoke exhaust must be cleaned depends on the use of the boiler and the type of
installation.
We recommend contacting an authorised service centre for end-of-season maintenance and cleaning as the abovementioned operations will be performed together with a general inspection of the components.

10-MAINTENANCE AND CLEANING
END-OF-SEASON SHUTDOWN
At the end of season, before shutting down the boiler, we recommend completely removing pellets from the hopper with the use of a
vacuum cleaner with an extension.
The service fuse may have to be replaced if the control panel display does not go on when the product is re-started upon pressing the main
switch on the rear of the boiler.
On the rear of the boiler there is a fuse compartment which is located underneath the supply socket. Use a screwdriver to open the fuse
compartment and if necessary replace them (3.15 A delayed).
