Introduction Technical service - Rights reserved - Reproduction prohibited

INTRODUCTION

Dear Customer,
We wish to thank you for choosing one of our products, specifically a

stove from the Pellet line.
Products built with Oyster technology, thanks to a perfectly sealed

frame, do not consume oxygen by taking all the air from the
environment outside so therefore can be placed inside every home
properly insulated and within passive houses. Thanks to this
technology, there are no risks of smoke emissions in the environment
and the air grilles are no longer necessary. As a result, there will no
longer be flows of cold air that make the environment less comfortable,
compromising the overall efficiency of the system.

In the case of forced ventilation or rooms that could have a negative
vacuum in comparison to the outside, an airtight stove can be installed.

In order to get the best performance from your stove and to
enjoy to the full the warmth and the sense of well-being which
the flame will diffuse through the home, we recommend that
you read this booklet carefully before lighting the s

tove for the first time.
While thanking you again, may we remind you that the stove MUST

NOT be used by children, and that they must always be kept at a safe

distance from it!

2. Theoretical notions for installation

2.1. 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 comes from the lignin which is contained in the wood itself, and
allows the production of pellets without the use of glues or binders.

The market offers different types of pellet with characteristics which
vary depending on what mixture of woods is used. The diameter varies
between 6 mm and 8 mm, with a standard length in the range 5 mm to
30 mm. Good quality pellets have a density which varies between 600
kg/m3 and 750 kg/m3, with a moisture content which varies from 5%
to 8% by weight.

Besides being an ecological fuel (exploiting timber residues to the
maximum and achieving cleaner combustion than is possible with fossil
fuels), pellets also have technical advantages. While good-quality
timber has a calorific power of 4.4 kW/kg (with 15% moisture,
therefore after about 18 months' seasoning), the equivalent figure for
pellets is 4.9 kW/kg.

To ensure good combustion, the pellets must be stored in an area that
is free of humidity and protected from dirt. The pellets are usually
supplied in 15 kg. sacks, so storing them is very convenient.

Good quality pellets ensure good combustion, thus lowering the
emission of harmful agents into the atmosphere.

The poorer the quality of the fuel, the more
frequently will intervention be necessary for cleaning
the internal parts, such as the grate and the
combustion chamber.

The main certifications of quality for pellets in the European market are
DINplus and Ö-Norm M7135; these ensure respect of:

 Calorific power: 4.9 kWh/kg
 Water content: max 10% of weight
 Percentage of ashes: max 0,5% of weight
 Diameter: 5 – 6mm
 Length: max 30mm
 Contents: 100% untreated wood, with no added bonding

substances (bark percentage 5% max)

 Packaging: in sacks made from ecologically compatible or

biologically decomposing material

Theoretical notions for installation Technical service - Rights reserved - Reproduction prohibited

The company strongly recommends the use of
certified fuel for its stoves (DINplus and Ö-Norm
M7135).

The use of fuel of inferior quality or not conforming
to the specification given above compromises the
running of your stove and can therefore lead to the
termination of the guarantee and of the
manufacturer's responsibility for the product.

Pellet stoves only work with pellets having a
diameter of 6-8 mm with a length ranging from 5mm
to max 30 mm.

2.2. PRECAUTIONS FOR INSTALLATION

IMPORTANT!
Installation and assembly of the stove must be

carried out by qualified personnel.

The stove must be installed in a suitable position to allow the normal
operations of opening and ordinary maintenance.

The site must be:

 capable of providing the environmental conditions for operation
 equipped with power supply 230V 50 Hz
 capable of taking an adequate system for smoke discharge
 provided with external ventilation
 provided with an earth connection complying with CE

The stove must be positioned in such a way that the electrical
plug is accessible.

IMPORTANT!
The stove must be connected to a flue pipe or a

vertical duct which can discharge the fumes at the
highest point of the building.

The fumes are however derived from the combustion
of wood products, and if they come into contact with
or close to walls, they can make dirty marks.

Also take care because the fumes are very hot but
almost invisible, and can cause burns on contact.

The holes for the passage of the smoke pipe and for
the intake of air from outside should be made before
positioning the stove unit.

2.3. OPERATING AREA

If installing together with other heating equipment, provide suitable air
intakes for each (according the indications of each product).

It is not permissible to install the stove in bedrooms,
bathrooms, or in a room where another heating
appliance is installed (fireplace, stove etc.) which
does not have its own independent air intake.

Locating the stove in a room with an explosive
atmosphere is prohibited.
The floor of the room where the stove is to be
installed must be strong enough to take its weight.

2.3.1. Safe distances

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

If the floor is wooden, we recommend the use of a
floor guard in compliance with the applicable
standards in force in the country of installation.

2.4. CONNECTION TO THE COMBURENT AIR INLET
PIPE (1)

Pipes and unions with suitable gaskets must always
be used, to guarantee a hermetic seal.

Products built with Oyster technology, thanks to a perfectly sealed
frame, do not consume oxygen by taking all the air from the
environment outside so therefore can be placed inside every home
properly insulated and within passive houses.

In order to satisfy these requirements, the connection pipe, with a
diameter of 80 mm, for the comburent air inlet (1) must be
connected outside the building.

The air intake must also:
 be protected by a grill, made of metallic anti-insect mesh or a

suitable protection as long as it does not reduce the minimum
section.

 be installed so as to avoid obstruction
 the maximum permitted length for the duct is 6 m with two 90°

curves

The stove must be connected to the external air
intakes with pipes and unions that guarantee a
hermetic seal to fulfil the requirements of an airtight
stove (OYSTER technology).

2.5. CONNECTION OF SMOKE DISCHARGE PIPE (2)

When making the hole for the passage of the smoke discharge pipe, it
is necessary to take into account the possible presence of flammable
materials. If the hole will be going through a wall made of wood or any
other material which is sensitive to heat, the INSTALLER MUST first
of all use the special wall union (diam.13cm 13cm minimum) and
properly insulate the pipe of the stove that passes through it, using
adequate insulation materials (thickness 1.35cm with minimum thermal
conductivity of 0.07 W/m°K).

The same is true if the stove pipe must run through vertical or
horizontal stretches passing in proximity (min.20cm) to the heat­sensitive wall

As an alternative we recommend the use of insulated pipe, which can
also be used on the outside to avoid condensation.

The combustion chamber works in low pressure. The smoke duct for
the discharge of fumes will also be under low pressure when connected
to an efficient flue pipe as directed.

Pipes and unions with suitable gaskets must always
be used, to guarantee a hermetic seal (class P1,
reference standard EN 1856-2).

All sections of the smoke duct must be inspectable and
removable to enable periodic internal cleaning. Tee
connectors with inspection caps should be used.

Position the stove bearing in mind all the instructions and
considerations above.

IMPORTANT!
All 90 degree changes of direction in the flue pipe

must be fitted with suitable tee connectors to allow
the possibility of inspection. (see accessories for
pellet stove)

It is absolutely prohibited to fit a grille on the end of
the discharge pipe, because it could lead to poor
running of the stove.

FOR CONNECTION TO THE FLUE PIPE, NOT MORE
THAN 2-3 METRES OF HORIZONTAL PIPE MUST BE
USED AND NOT MORE THAN THREE 90° CURVES
MUST BE USED

IT IS ALSO ADVISABLE NOT TO EXCEED 6 METRES IN
LENGTH WITH THE PIPE Ø 80 mm

2.6. CONNECTION TO THE FLUE PIPE

The flue pipe must have internal dimensions not larger than 20 x 20
cm, or diameter 20 cm. In the event of larger dimensions, or of the
flue pipe being in poor condition (for example cracks, poor insulation,
etc.), it is advisable to fit a stainless steel pipe of suitable diameter
inside the flue pipe throughout its length, right up to the top.
Check with suitable instruments that there is a minimum draught of 10
Pa.
At the bottom of the flue pipe, provide an inspection cap to allow
periodic checking and cleaning, which must be done annually.
Make a gas-tight connection to the flue pipe, using pipes and
connectors as recommended by us.
You must ensure that a windproof cowl should be fitted which complies
with the standards in force.

This type of connection ensures the evacuation of the
fumes even in the event of a temporary power cut.

2.7. CONNECTION TO AN EXTERNAL FLUE WITH
INSULATED OR DOUBLE-WALL PIPE

The external fluepipe must have internal dimensions of minimum
10x10 cm or 10 cm diameter, and maximum 20x20 cm or 20 cm
diameter.
Check with suitable instruments that there is a minimum draught of 10 Pa.
The only type of pipe which is permissible is insulated (double-walled)
stainless steel, smooth on the inside, fixed to the wall. Flexible stainless
steel pipe must not be used. At the bottom of the flue pipe, provide an
inspection cap to allow periodic checking and cleaning, which must be
done annually. Make a gas-tight connection to the flue pipe, using
pipes and connectors as recommended by us.
You must ensure that a windproof cowl should be fitted which complies
with the standards in force.

This type of connection ensures the evacuation of the
fumes even in the event of a temporary power cut.

2.8. CONNECTION TO THE FLUE PIPE

For proper functioning, the connecting pipe between the stove and the
chimney or flue duct must have a slope of not less than 3% in the
horizontal stretches, the length of which must not exceed 2/3
metres, and the vertical distance between one tee connector and
another (change of direction) must not be less than 1.5m.
Check with suitable instruments that there is a minimum draught of 10
Pa.
At the bottom of the flue pipe, provide an inspection cap to allow
periodic checking and cleaning, which must be done annually.
Make a gas-tight connection to the flue pipe, using pipes and
connectors as recommended by us.
You must ensure that a windproof cowl should be fitted which complies
with the standards in force.

This type of connection ensures the evacuation of the
fumes even in the event of a temporary power cut.

2.9. OPERATING PROBLEMS CAUSED BY DRAUGHT
DEFECTS IN THE FLUE

Of all the weather and geographical conditions which affect the
operation of a flue pipe (rain, fog, snow, altitude a.s.l., exposure to
sunlight, direction of facing), the wind is unquestionably the most
decisive. In fact, along with thermal depression caused by the
difference in temperature inside and outside of the chimney, there is
another type of depression or over-pressure: dynamic pressure caused
by the wind. An updraft always increases depression and hence
draught. A crosswind increases depression provided the cowl has been
installed properly. A downdraft always decreases depression, at times
inverting it.

Besides the direction and force of the wind, the position of the flue and
the cowl with respect to the roof of the building and the surrounding
landscape is important.

The wind also influences the operation of the chimney indirectly by
creating high-pressure and low-pressure zones, not only outside the
building but inside as well. In rooms directly exposed to the wind (2),
an indoor high-pressure area can be created which can augment the
draught in stoves and fireplaces, but it can be counteracted by the
external high pressure if the cowl is situated on the side exposed to the
wind (1). On the other hand, in the rooms on the opposite side from
the direction of the wind (3), a dynamic depression can be created
which competes with the natural thermal depression developed by the
chimney, but this can be compensated for (sometimes) by locating the
flue on the opposite side from the direction of the wind (4).

IMPORTANT!
The operation of the pellet stove is noticeabl

y

sensitive to the conformation and position of the flue
which is adopted.

Hazardous conditions can only be overcome by
suitable setting-up of the stove carried out by
qualified personnel.

3.2. PREPARATION AND UNPACK ING

The DALIA OYSTER stove is delivered in one sole package formed

of:

o Structure packaging
o Side and top packaging (Fig.1)

Open the packaging, remove the four screws that secure the base of
the stove to the pallet, two to the right and two to the left (see figure

4), and position the stove in the selected place, ensuring that it is
complies with the above instructions.

The stove body or unit must always be kept in a vertical position when
moved, and moved only using carts. Special care must be used to
protect the door and the glass from impacts that would damage them.

Moving the product must always be done with care. If possible, unpack
the stove in the area where it is going to be installed.

The materials which make up the packaging are not toxic or harmful,
so no special procedures for disposal by required.

Their storage, disposal or possible recycling are therefore the responsibility
of the final user, in compliance with current legislation on the subject.

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 operations for connection 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 connect up with the flue), take the greatest
care to make sure that the joint is not stressed.

3.4. MAKING THE ELECTRICAL CONNECTIONS

Connect the supply cable first at the rear of the stove and then to an
electrical outlet on the wall.

The main switch located on the rear of the stove should be switched on
only when you want to light the stove.

If you do not intend to use the stove, it is advisable
to keep it switched off.

4. OPERATION

4.1. PRE-LIGHTING WARNINGS

Do not touch the stove during the first lighting, as it
is during this phase that the paint sets. If you touch
the paint, you may expose the steel surface.

If necessary, touch up the paint with the aerosol spray in the original
colour (see the section "Accessories for pellet stoves").

It is recommended to provide plenty of ventilation in
the room during the initial lighting, as the stove will
give off a small amount of smoke or odour due to the
stabilisation of the paint.

Do not stay near the stove, and as previously mentioned, ventilate the
room. The smoke and the smell of paint will vanish after about one
hour of operation. There are no health risks involved.

The stove will be subject to expansion and contraction during the
stages of lighting and cooling down, and may therefore make slight
creaking noises.

This phenomenon is absolutely normal, the structure being made of
sheet steel, and must not be considered a fault.

It is extremely important to be sure not to take the stove to full heat
straight away, but to bring it gradually up to temperature.

If use low heating powers (for example 1

a-2a-3a

). During subsequent
use, you will be able to make use of all available heating power (e.g.
4

a-5a

).

In this way you will avoid damage to the ceramic panels, the welds and
the steel structure.

Do not demand maximum heating
performance immediately!

As with automobiles, a running-in period is
recommended, even if only for a short period of
time (4/5 hours).

Try to get familiar with the commands given from the control panel.

4.2. PRE-LIGHTING CHECK

Check that all the safety conditions described above have been met.
Make sure you have read and completely understood the contents of

this instruction booklet.
Remove any components which might burn from the firebox and from

the glass (various instructions and adhesive labels).
Check that the grate A is properly positioned and rests correctly on the

base.

After long periods of disuse, remove from the hopper (using
a vacuum cleaner with an extension) any remains of
pellets which have lain there for some time, since they may
have absorbed moisture, which changes their original
characteristics and makes them unsuitable for burning.

4.3. LOADING THE PELLETS

Fuel is loaded from the upper part of the stove by opening a door. Pour
the pellets in the hopper; when empty, it will hold about 10 kg.

To make the process easier, do this slowly and continuously. In
addition:

 Do not pour the pellets up to the level of the gasket,

because otherwise the door will not close correctly and
the stove will not be airtight, tripping alarm A04 (see
par.). It is advisable to pour the pellets up to the lower
limit shown by the arrow (fig. to the side).



Never remove the protection grille in the hopper.
When filling, do not let the sack of pellets touch any
hot surfaces.

Do not place any type of fuel in the hopper other than
pellets that are compliant with the specifications
provided previously.

Store the fuel supply at a suitable safety distance.
Do not pour pellets directly into the brazier but just in

the hopper.
Be very careful when touching the hopper door when

the stove is on because you could burn yourself.
Most of the stove surfaces are very hot (door, handle,

glass, smoke outlet pipes, hopper door, etc) therefore
it is recommended not to come into contact with these
parts without using suitable protective garments.

4.4. DISPLAY PANEL AND COMMANDS

4.4.1. Control panel logic

Shown below is some useful information for understanding the logic
and use of the control panel:

 Knob A has 5 ventilation levels. The knob rotates uniformly

from min to max.

 Knob B allows the room temperature to be regulated. The

temperature ranges from a minimum of 15°C to a maximum of
30°C, also in this case the knob turns uniformly.

 Knob C foresees 5 levels of flame regulation (power); the key

rotates uniformly.

 Key D allows the stove to be ignited (ON) or shutdown (OFF).
 Key E increases or decreases pellet load respect to the factory

default value which is 0. When the stove is lit for the first
time, the set setting is 0 (led in the middle), by using key E
you increase (led to the right+1/+2) or decrease (led to the
left-1/-2) the pellet load. The selected led will remain fixed
orange while the stove is operational, it will go out when the
stove is switched off and the last setting will stay in the
memory when it is lit again.

 Led 1 – when the stove is lit the led is green and fixed,

flashing green when igniting/setting the stove and flashing
yellow/orange when it is switched off; it flashes red in the case
of the intervention of an alarm.

 The 5 leds over key E (0/-1/-2/+1/+2) also light up to signal

alarms. In the event of an alarm, LED 1 will flash red, an
acoustic signal will be emitted and the type of alarm will be
displayed by the corresponding LEDs.

4.5. STOVE POWER SUPPLY

Once the power cord is connected to the rear part of the stove, place
the switch, also on the rear, to position (I).

The lighted button of the switch will come on.
The switch located to the rear of the stove powers the system.

On the rear of the stove there is a fuse box which is located
underneath the mains socket. Use a screwdriver to open the fuse box
if necessary replace them (3.15 A delayed).

4.6. FIRST LIGHTING

4.6.1. Ignition/shutdown using the control panel

(Key D)

The stove is ignited and shutdown by pressing key D on the control
panel for 2 seconds.

When switching on, LED 1 flashes green, whereas when the stove is lit
it is fixed green.

After a start-up phase lasting about 20 minutes, the stove
enters into full working order (led 1 lit with fixed green light).

Key D is also used to switch the stove off (see section.4.8).

4.7. OPERATING MODE

4.7.1. Setting room temperature (Knob B)

By using command B it is possible to set the desired temperature for
the room in which the stove is installed from a minimum of 15°C to a
maximum of 30°C.

When such condition is obtained the stove goes into a status
corresponding to the minim values of consumption (flam and hot air fan
speed at minimum, see following points), to then return to the set
values when the room temperature drops below the set threshold.

4.7.2. Setting the flame power (Knob C)

Using command C the flame power is set from a minimum of 1 to a
maximum of 5.
The levels of power correspond to a different fuel consumption value:
by setting 5 the room will be heated in less time, setting 1 the room
temperature will be maintained for a longer period of time.

The flame power setting is only effective after
ignition and therefore in full working order.

Operation Technical service - Rights reserved - Reproduction prohibited

4.7.3. Setting the hot air fan speed (Knob A)

Using command A the hot air fan speed can be regulated.

The fan starts to work when the stove has reached a
default (factory setting) temperature value.

During the switch off process, the fan stays on until
the stove has cooled down.

4.7.4. Note on first ignition

The first attempt at ignition may not be successful,
since the feeder screw is empty and it is not always
able to fill the grate with required amount of pellets
in time to ensure normal ignition

CANCEL THE CONDITION OF ALARM FOR FAILED
IGNITION BY PRESSING KEY D FOR A FEW SECONDS
(see section 4.17). REMOVE THE PELLET LEFT IN THE
BURNER AND REPEAT IGNITION

After repeated attempts at lighting, if there is no flame even though
pellets are flowing normally, check that the grate is correctly
positioned. It must be placed where it adheres perfectly to its
housing and free of any ash incrustations. If after this check no
abnormalities are found, it means that there may be a problem with the
stove components or that installation may not have been carried out
correctly.

REMOVE THE PELLETS FROM THE BURNER AND
CONTACT AN AUTHORISED TECHNICIAN.

4.8. SHUTDOWN MODE (Key D)

The stove is shutdown by pressing key D. From this moment a
completely automatic cooling phase begins which includes the
interruption of loading the fuel, cleaning the grate and the smoke
discharge conduit.
Such phase may last for a variable time according to how many hours
the stove has been lit and its position; the smoke blower fan will
revolve until the minimum default temperature (factory setting) is
reached.

NEVER SHUTDOWN THE STOVE BY CUTTING OFF THE
MAINS.

Always leave it to complete the shutdown cycle,
otherwise damage could be caused to the structure,
and also problems with ignition in the future.

4.9. CHOOSING THE TYPE OF PELLET LOAD (Key E)

This operation allows the user to set the stove in the best way based
on the type of pellet available.
This prevents fuel waste, ensures expected heating ability and protects
the condition of the product.
Depending on the characteristics shown below (shape/colour/ nature of
flame) and user's experience (grate too full or too empty) it is possible
to use key E, respect to the factory default (0), to increase or decrease
pellet load.

THE CHOICE OF LOAD TYPE (0 factory
default, -1/-2/+1/+2) CAN BE MADE ON
FIRST INSTALLATION OR EVERY TIME IT
IS NECESSARY. (E.g. when you change supplier or

when you notice differences in colour or size of the
pellets)

4.10. SUCTION UNIT SPEED SELECTION

In the installation proves difficult for smoke discharge (lack of draught
or even pressure in the conduit), it is possible to increase the smoke
and ash exhaust speed. Such modification is also the best way to solve
all potential problems of pellet blockages in the grate and sediments on
the bottom of the grate which are created by bad quality fuel or which
release a lot of ash.

Press keys D and E simultaneously for a few seconds until LED 0 begins
to flash: now use key E to increase or decrease the suction unit speed
setting:

 LED -2 = -20%
 LED -1 = -10%
 LED 0 = default
 LED +1 = +8%
 LED +2 = +15%

4.11. VIEWING THE FLAME

In order to obtain good operation from the stove, you need to know
how to "read" the flame. The characteristics that the user needs to pay
attention to are the basically:

 The shape
 The colour
 The character

4.11.1. The shape

In normal combustion, the flame should be tapered and lively, as

wide as the grate that it comes out of and with the tip roughly vertical
or pushed towards the Alutec70 back of the firebox. You should have
the sensation that the flame is pulled upward so that it does not beat
against the glass of the door.

Fig. 1

On the other hand a flame which at its base is bigger than the grate
and has a feeble character, whose tip is not "guided", or which beats
against the glass

(Fig. 2)

may be a symptom of poor setting of the fuel
loading and/or smoke aspiration, or the smoke duct is obstructed or
there are high pressure areas that do not allow for regular smoke
outflow.

In this case you will ALWAYS have operating problems. Request
assistance from specialized personnel or ask technicians for advice.

4.11.2. The colour

The colour is in some way connected to the shape of the flame. A
colour which varies between orange and yellow with a dark tip usually
goes along with an enlarged flame (as previously described) which
lacks oxygen or in any case indicates improper combustion. As the
colour changes to light yellow-white, the shape of the flame changes,
becoming thinner, showing the presence of a greater quantity of
oxygen.

4.11.3. Character

Lively or feeble, this is closely connected to the shape of the flame.

NORMAL COMBUSTION
Shape: Tapered, compact, vertical
Character: Lively
Colour: Yellow – light yellow - white

ABNORMAL COMBUSTION
Shape: enlarged irregular not

compact

Character:Tenuous - feeble
Colour:Orange - yellow

4.12. Connection to a room thermostat

The room thermostat is not included with the stove
and it must be installed by a specialised technician.

WARNING!
The electrical wires must not be in contact with the

hot parts of the stove.

The stove can also be connected to a room thermostat. The procedure
to follow for the connection of the external thermostat is the following:

 Connect the two wires of the cable which come from the room

temperature to the two free terminals of the connector
(position 13 wiring diagram chap.7). To do this it is
necessary to:

o unscrew the protective cap of the probe
o Pass the two wires through the protective cap and

insert them into the hole together with the probe.

o Pull the two wires to carry out connection to the board

corresponding to terminal 13 (see chap.7)

o Close the protective cap again.

4.13. Accessing the motherboard

Perform the following operations working behind the stove:

 remove the four screws X
 remove the cover U
 remove the two screws Y
 remove the cover U
 remove the motherboard S

Make the connections to the card and replace the covers V and U.

POS.13

CA VO TERMOSTATO
AMBIENTE

To make the stove work according to the temperature set on the
external thermostat it is necessary to bring knob (B) to the minimum
position (15°C).

Please remember that once the temperature is reached, the stove does
not switch off but automatically modulates the flame and room fan to
minimum power. The stove will only switch off if the Eco-Stop function
is active.

4.14. Operation with ECO-STOP

The Eco-Stop function automatically switches the stove off when the
room reaches a satisfactory temperature and switches the stove back
on again when room temperature drops.

Activation: press the On/Off button briefly 5 times in a row within a
period of 6''. The card responds by sounding a long beep to confirm (3
seconds).

 During operation with Eco-Stop active the green led remains

on for 5 seconds and switches off for 2 seconds, rather than
staying on permanently.

 When the temperature is reached (satisfied temperature of

probe on the edge of the stove and (if present) external open
contact thermostat) the stove begins to the Eco-Stop count.
This prompts a gradual transition to Power level 1. The system
remains in this state until the counter reaches 20' and then, if
the temperature is still satisfactory, begins the switch off
process. On the other hand, if during these 20' the
temperature once again becomes unsatisfactory for a few
seconds (to exclude a momentary indication), the count
immediately zeros.

 When Eco-Stop switches the stove off this is signaled by

orange and green leds flashing alternately every 2''.

Operation Technical service - Rights reserved - Reproduction prohibited

 When Eco-Stop puts the stove into stand-by mode this is

signaled by green and orange leds flashing alternately every
2''.

 Eco-Stop switches the stove back on when both of the

following conditions are present:
 At least 5' have elapsed since the switch off process

began.

 Room T is at least 2°C below the set temperature (e.g. set

to 20°C, restarts when the temperature drops to 18°C).

 If an external thermostat is used for operation, this is the

element that controls re-starting (e.g. in some thermostats
the delta can be set to between 0.5°C and 1.5°C).

 N.B.: to exclude a momentary indication, the

aforementioned conditions must be present for 10''
consecutive.

 When Eco-Stop switches the stove back on, this is indicated by

a green flashing led (as with normal start-up).

 If the stove is switched off manually using the On/Off button

while Eco-Stop is active, the next time the stove is restarted
the function will still be active.

 If there is a black-out while the stove is switched on or in

stand-by mode with Eco-Stop active, when the stove restarts
Eco-Stop will switch it off and then on again (if the
temperature is not satisfactory, with a delay of 120'').

Deactivation: press the On/Off button briefly 5 times in a row within a
period of 6''. The card responds by sounding a long beep to confirm (4
seconds).

4.15. Connection to programmable timed

thermostat (optional RED accessory)

The room timer is not included with the stove. The
user is responsible for fitting this part.

Refer to the instructions given in the optional programmable timed
thermostat for information on how to install it.

4.16. SAFETY DEVICES

The stove is fitted with the following safety devices:

 MAIN STOVE POWER SUPPLY SAFETY

The stove is protected by a fuse which is near to the switch (I).

 SMOKE TEMPERATURE SENSOR.

Monitors the temperature of the smoke, and gives permission for
start-up or shuts the stove down when the smoke temperature
falls below the preset value.

 PELLET HOPPER TEMPERATURE SENSOR.

If the temperature exceeds the preset safety level, it immediately
shuts down the running of the stove, and has to be reset, after the
stove has cooled, before the it will restart.

 ELECTRICAL SAFETY

The stove's electronic board is protected by a fuse. (see section.7).

 FAILURE OF THE SMOKE EXTRACTION FAN

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

 BREAKDOWN OF THE REDUCTION MOTOR

If the reduction motor stops, the stove continues to function until
it has cooled down to the minimum level.

 TEMPORARY POWER CUT

If there is a power outage during operation, when the power
comes back on the stove will go into cooling mode.

 FAILURE TO LIGHT

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

TAMPERING WITH THE SAFETY DEVICES IS
PROHIBITED

It is only after eliminating the cause which gave rise to the
intervention of the safety system, that it is possible to
relight the stove and thus reset the automatic operation of
the sensor. To understand which anomaly has occurred,
consult this manual which explains what to do based on the
alarm message the stove displays.

ATTENTION

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

 Failure when carrying out works of maintenance,

cleaning and repair to adopt all necessary measures and
precautions

 Tampering with the safety devices.
 Removing the safety devices.
 Failure to connect the stove to an efficient system for the

discharge of smoke.

 Failure to check in advance that the room where the

stove is to be installed is adequately ventilated.

5. MAINTENANCE AND CLEANING

ATTENTION!
All cleaning of all parts must be carried out with the

stove completely cold and unplugged.

The stove does not need much maintenance if used with
certified quality pellets.

5.1. DAILY AND WEEKLY CLEANING BY THE USER

5.1.1. Before each lighting

Using a suitable tool clean the grate “A” of ash and any incrustation
which could obstruct the passage of air.

In the case of pellet depletion, unburnt pellet in the grate could
accumulate in the hopper. Always empty the residuals from the grate
prior to each lighting.

REMEMBER THAT ONLY A CORRECTLY POSITIONED
AND CLEAN GRATE CAN GUARANTEE THE OPTIMAL
LIGHTING AND OPERATION OF YOUR PELLET STOVE.

For good cleaning of the grate, pull it completely out of its housing and
thoroughly clean the grate and holes on the bottom. If you use good­quality pellets, you will normally only need to use a paintbrush to
restore the perfect condition of the component. For tough incrustations,
use the steel tool provided with the stove.

5.1.2. Check every 2/3 days

Clean compartment “S” around grate “A” from ash being careful of hot
ashes.

Only if the ash is completely cold, it is possible to use a vacuum
cleaner 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 used, will determine the
frequency of cleaning.

It is however advisable not to let it exceed 2 or 3 days.

5.1.3. Cleaning the glass

For cleaning the ceramic glass, the use of a dry brush is recommended,
or if it is very dirty, the special spray detergent, applying a small
quantity then cleaning with a cloth.

ATTENTION!
Do not use abrasive products and do not spray the

cleaning product on the glass of the painted parts or
on the gaskets of the fire door (ceramic fibre cord)

5.2. PERIODIC CLEANING BY A SPECIALISED

TECHNICIAN

5.2.1. Cleaning of the heat exchanger

Halfway through the winter, but especially in the spring, you will
need to clean the compartment where discharge smoke passes.

This cleaning must

be done in order to remove all combustion residues
before time and humidity let them harden and make them difficult to
remove.

It is good practice to provide plenty of ventilation in
the room when cleaning the stove.

CLEANING THE DALIA OYSTER STOVE EXCHANGER:

While the stove is cold, open the door, remove the plate “M”, remove
the brazier “N” with the pellet deflector; raise the back panel “H”
slightly (beware as it breaks easily) and remove it.
Next, remove the top plate “O” by prising it off at the slots “X” at the
bottom using a screwdriver then insert the cold hand or another tool
into the two slots “Y” at the top and lift the plate “O”. Tilt it slightly to
extract it.
Use a rigid rod or bottle brush to scrape clean the walls of the
combustion chamber inside plate “O” (just removed) so that the ash in
the lower ash collection compartment falls.
When the upper exchanger has been cleaned remove plate“L”by
removing the two screws and using the nozzle of the vacuum cleaner to
remove the ash and soot that has accumulated in the lower exchanger
and in the area around brazier “N”. Clean and refit everything.

CLEANING OF SMOKE DUCT AND GENERAL CHECKS:
Clean the smoke discharge system, especially in the area of the

tee connectors, curves and any horizontal stretches of pipe.

For information on cleaning the flue pipe, contact a professional
chimney sweep.

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

ATTENTION:
The frequency with which the smoke discharge

system is cleaned should be determined based on the
type of use that is made of the stove and the type of
installation.

We recommend relying on an authorized service
centre for end-of-season cleaning and maintenance,
they will carry out all of the previously mentioned
work and make a general check of the stove's
components.

5.2.2. Shutting the stove down (end of season)

At the end of season, before shutting down the stove, we recommend
completely removing pellets from the hopper with the use of a vacuum
cleaner with an extension.

During periods of disuse, the stove must be unplugged and
placed in a dry place protected from the elements. For greater
safety, especially if there are children around, we recommend
removing the supply cable from the rear of the stove.

Upon re-start, when pressing the main switch (located on the back of
the stove) does not make the control panel display light up, it could
mean that the service fuse needs replacing.

On the rear of the stove there is a fuse holding compartment which is
located underneath the supply socket. Use a screwdriver to open the
fuse-holder compartment and if necessary replace them (3.15 AT
delayed)

5.2.3. Check of internal components

ATTENTION!
The check of the internal electro-mechanical

components must be carried out only by qualified
personnel with technical knowledge of electricity and
combustion.

We recommend that an annual maintenance service is carried out,
preferably under a programmed service contract. The essential part of
this service is a visual and functional check on the internal components:

The following is a summary of the checks and/or maintenance tasks
which are indispensable for the correct operation of the stove.
