1. WARNINGS AND SAFETY
The stoves manufactured in our factory are built with the
maximum dedication to the individual components so as
to protect both the user and the installer from accidents.
Authorized personnel are therefore advised to pay special
attention to the electrical connections after any servicing
operation on the product, especially with regard to the
stripped part of the wires, which must not protrude in
any way from the terminal block to prevent possible
contact with the live parts of the wire.
Installation must be carried out by aut orized
personnel, w o must issue t e purc aser a
declaration of compliance of t e system. T e
purc aser s all assume responsibility for t e
definitive installation and consequent proper
operation of t e product installed. It is necessary
to bear in mind all t e national, regional,
provincial and municipal laws and regulations
present in t e country in w ic t e appliance is
installed.
Extraflame S.p.A. may not be eld responsible in
t e event of failure to observe t ese precautions.
This instruction manual constitutes an integral part of the
product. It must always accompany the appliance, also
when it is transferred to another owner or user or moved
to another location. If the manual gets damaged or lost,
ask your local service centre for another copy.
This stove must only be used for the applications for
which it was expressly designed.
The manufacturer declines any responsibility,
contractually or extra-contractually, for any damage
caused to persons, animals or property by errors in
installation, adjustment, and maintenance, or by
improper use.
After removing the packaging, check to make sure that
the contents are intact and complete.
If this is not the case, contact the vendor from whom the
appliance was purchased.
The electrical components of the stove must only be
replaced with original spare by an authorized service
centre.
General stove maintenance must be carried out at least
once a year, scheduled sufficiently in advance with the
service centre.
T e following safety precautions must be
observed:
Do not allow the stove to be used by children or
unassisted disabled persons.
Do not touch the stove if you are bare-footed or if parts
of your body are wet or damp.
odifying the safety or adjustment devices without the
manufacturer’s approval or instructions is forbidden.
Never pull, detach, or twist the electrical cables coming out
of the stove, even if it is disconnected from the electrical
power.
Do not plug or reduce the size of the air vents of the room
in which the stove is installed.
The air vents are critical for correct combustion.
Keep the packaging materials out of the reach of children
and unassisted disabled persons.
Prior to installation, we recommend that you thoroughly
clean all the piping of the system to remove any residues
that could jeopardise the efficient operation of the
appliance.
During installation, the user should be informed that:
a. In the event of water leakage, the water supply must be
closed off and the service centre must be notified promptly.
b. The operating pressure of the system must be checked
periodically. When the stove is not used for an extended
period of time, we recommend asking the technical service
to carry out at least the following operations:
- Put the master switch in position 0.
- Close the water taps on both the heating and plumbing
systems.
- Empty the heating and plumbing systems if there is a risk
of freezing
During normal functioning of the product the door of the
furnace must always be closed.
Avoid direct contact with parts of the appliance, which tend
to heat up during functioning.
Check for the presence of any obstructions before switching
the appliance on following a long standstill period.
The stove has been designed to function in any climatic
conditions (even critical), in particularly adverse conditions
(strong wind, ice) safety systems may intervene, which
switch the stove off.
If this happens, contact the after-sales service and do not
disable the safety systems in any case.
If the flue should catch fire use adequate systems to
suffocate the flames or request help from the fire brigade.

3. WHAT ARE PELLETS?
The pellets are made by applying very high pressure to sawdust, that is pure timber waste
(without paint), produced by sawmills, carpentry works and other activities associated with the
working and transformation of timber.
This type of fuel is completely environmentally friendly as no binders of any kind are used to keep
it compact. In fact, the compactness of the pellets over time is guaranteed by a natural substance
found in the wood itself: the lignite.
As well as being environmentally friendly, as the wood residues are exploited to the maximum,
pellets also have technical advantages.
While wood has a calorific power of 4.4
kW/kg. (with 15% humidity, after about 18 months seasoning) the power of pellets is 5.3 kW/kg.
The density of the pellet is 650kg/m3 and the water content is 8% of its weight. For this reason,
the pellets do not need to be seasoned to obtain an adequate calorific yield.
The pellet used must conform to the characteristics of the following regulations:
•Ö-Norm 7135
•DIN plus 51731
•UNI CEN/TS 14961
Extraflame recommends always using 6 mm pellets for its products.
3.1 Pellet storage
To guarantee problem-free combustion, the pellet must be stored in a dry place.
3.2 Pellet loading
To load the pellets, open the tank cover positioned on the upper part of the stove and empty the
bag of pellets, paying attention not to let them escape.
WARNING
THE USE OF POOR QUALITY PELLETS OR OF ANY OTHER ATERIAL AY DA AGE THE
FUNCTIONING OF YOUR STOVE AND LEAD TO THE INVALIDATION OF THE WARRANTY
AND ASSOCIATED RESPONSIBILITIES
OF THE ANUFACTURER.

4. SAFETY DEVICES
4.1 Breakdown of flue gas extractor
If the extractor stops, the electronic unit immediately prevents pellet feeding.
4.2 Breakdown of pellet load motor
If the motor stops, the stove continues to operate until the minimum cooling level is reached.
4.3 4 Failed ignition
If no flame develops during the ignition phase, the appliance automatically attempts a new ignition, this
time, though, without loading pellets.
If, after this attempt, the stove still has no flame, the stove display shows “FAILED IGNITION”. If you
attempt to light the stove again, the display shows “COOLING WAIT” which means “WAIT”. T is function
reminds you t at before lig ting t e stove, you must be sure t at t e brazier is free of dirt and
debris.
4.4 Temporary power cut
The appliance will re-light automatically after a brief power failure. When the power goes off, the stove may
emit a minute quantity of smoke inside the house for a period of 3 to 5 minutes.
THIS DOES NOT POSE ANY SAFETY RISK.
4.5 Electrical safety device
The stove is protected against violent changes in power by a master fuse on the rear of the stove (2A 250V
delayed).
4.6 Flue gas ex aust safety device
If the exhaust system fails, an electronic pressure switch stops the stove and an alarm is signalled.
4.7 Pellet temperature safety device
In case of overheating inside the pellet tank, this safety device blocks stove operation; resetting is manual
and must be performed by an authorised technician.
4.8 System pressure safety device
A mechanical pressure switch blocks any over-pressure in the system.
Resetting is manual and must be carried out by an authorised technician.
4.9 Boiling water safety device
In the event of a lack or minimum quantity of water, this device blocks the pellet feed. Reset is manual and
must be carried out by an authorised technician.
4.10 External devices
During stove installation, it is ANDATORY to adapt the system with a pressure gauge for viewing the water
pressure and an automatic discharge valve calibrated at 3 bar pressure.
4.11 Installation and safety devices
The installation and respective system connections, the start-up and final testing for correct operation must
be carried out with all due diligence by authorised professional technicians (Italian Law no. 46 of 5 arch
1990), in full respect for the regulations in force, both national and regional, as well as for the instructions
given in this manual.
Extraflame S.p.A. declines any responsibility for damage to objects and/or persons caused by
t e system.

5.2.1 Connection to t e flue gas venting system
Ex aust pipe or fitting
For the assembly of the exhaust pipes it is imperative to use non-flammable materials that are
resistant to combustion products and any condensates.
It is forbidden to use flexible metal pipes and asbestos cement for connecting the stove to the
flue, also for pre-existing exhaust channels.
There must be continuity between the exhaust pipe and the flue so that the flue does not lean on
the stove.
The exhaust pipes must not pass through rooms in which the installation of combustion devices is
forbidden.
The assembly of the exhaust pipes must be carried out in such a way as to ensure that they are
airtight for the operating conditions of the appliance, as well as to limit the formation of
condensates and prevent them from being conveyed towards the appliance.
The assembly of horizontal sections must be avoided where possible.
Where roof or wall exhaust outlets have to be reached that are not coaxial in relation to the
exhaust outlet from the appliance, the direction changes must be made using open elbows no
greater than 45° (see figures below).
For heat generating devices equipped with an electric exhaust fan, i.e. all products made by
Extraflame, it is necessary to observe the following instructions:
•Horizontal sections must have a minimum slope of 3% upwards.
•The length of the horizontal section must be as short as possible, and in any case no
greater than 3 metres.
•No more than four direction changes may be used, including the one resulting from the use
of the “T”-element. (When four bends are used, use double wall piping with a 100 mm
diameter.)
In any case, exhaust pipes must be sealed in relation to combustion products and condensates, as
well as insulated, if they pass outside the installation room.
It is forbidden to use elements in counter-slope.
The exhaust channel must allow soot recovery and cleaning using a swab.
The exhaust channel must have a constant cross-section. Any changes in cross-section are allowed
only at the flue connection.

5.2.3 Connecting t e appliance to t e flue and evacuation of combustion products
The flue must receive exhaust from a single heat generator.
Direct discharge towards enclosed areas, even when roofless, is forbidden.
Direct discharge of combustion products must take place on the roof and the exhaust pipe must
have the features set out in the section “Chimney or single flue” .
5.2.4 C imney cap
The chimney cap must meet the following requirements:
- have an internal section equivalent to that of the chimney;
- have a useful outlet section no less than twice the internal section of the chimney;
- be constructed in such a way as to prevent the penetration of rain, snow and foreign bodies into
the chimney, as well as to assure the discharge of the combustion products also in the presence of
winds coming from any direction and at any angle.
- be positioned in such a way as to assure proper dispersion and dilution of the combustion
products and, in any case, outside the reflux area in which the formation of counter-pressure is
most likely to occur. This area has different sizes and shapes depending on the slope of the roof;
therefore, it is necessary to use the minimum heights indicated in the figures below.
The chimney cap must not have any mechanical suction devices.

5.2.5 Connection to external air inlets
To ensure correct operation, the appliance must have sufficient air available by means of external
air inlets, which must meet the following requirements:
a) They must have a total free section of at least 80 cm².
b) They must be protected by a grate, metal mesh, or other suitable protection provided that it
does not reduce the minimum section as per point a) and that it is positioned in such a way as to
prevent the intakes from being obstructed.
If the combustion air is collected directly from the outside by means of a pipe, it is necessary to fit
a downward bend or a wind hood on the outside. In addition, no grating or similar device should
be positioned. (Extraflame S.p.A. suggests creating an air intake directly communicating with the
installation room, even if air is collected from outside by means of a pipe). Air inflow can also be
obtained from a room adjacent to the installation room, provided that the flow can occur freely
through permanent openings communicating with the outside.
The adjacent room must not be subject to depression with respect to the outside as a result of the
opposing draught caused by the presence of another utility device or suction device in this room.
In the adjacent room, the permanent openings must meet the requirements described above.
The adjacent room cannot be used as a garage, storage area for combustible material, or for
activities involving fire hazards.
5.2.6 Insulation, trims, facings, and safety precautions
The facings, no matter what type of material they are made of, must constitute a self-bearing
structure with reference to the heating assembly and not in contact with it.
The beam and the trims in wood or combustible materials must be positioned outside of the
radiant area of the hearth or be properly insulated.
If the space above the heat generator has coverings made of combustible or heat-sensitive
material, a protective membrane made of non-combustible insulating material must be placed
between it and the generator.
All elements made of combustible or flammable material, such as wooden furnishings, curtains,
etc., which are directly exposed to the radiance of the hearth, must be placed at a safe distance.
The installation of the appliance must guarantee easy access for cleaning the appliance itself, of
the exhaust gas pipes and the flue.
5.2.7 National, regional, provincial and municipal laws
All the national, regional, provincial ad municipal laws of the country where the appliance has been
installed must be taken into consideration.

9. OPERATING MODES
The stove is factory-set to receive a number of external supplementary thermostats that make it
possible to adapt and regulate operation in relation to the system needs.
In support of this function, the stove has three operating modes strictly tied to the use of external
thermostats, where used. This means that the selection of one mode over another without the use
of supplementary devices does not modify the stove in any way.
The external thermostats have to be connected to the terminal board located on the back of the
stove.
The installer must verify that supplementary device applied to the stove is suitably earthed; if
necessary, provide for an additional earth. Pay particular attention that the cables are not in
contact with heated parts.
On the back wall of the tank, just above the terminal board, there are four holes for attaching the
cable terminals that you will find in the bag of accessories.
The table below shows some examples of possible connections for external thermostats.
ING1  input connection between terminals ING1 and CO of the terminal board
ING2  input connection between terminals ING2 and CO of the terminal board
ING1 has priority over ING2
OUT3 and OUT4 are outputs of the supplementary board controlled by the status of input ING1.
The status of the outputs indicated in the table below are to be considered valid only when the
pump is working.
N.B.: Stove s utdown always as a delay of 15 minutes.
