1. PRECAUTIONS AND SAFETY
The stoves manufactured in our factory are built
with the ma imum 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. 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 e pressly designed.
The manufacturer declines any responsibility,
contractually or e tra-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 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 unattended
children or disabled persons.
Do not touch the stove if you are bare-footed or if
parts of your body are wet or damp.
Modifying 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 unattended 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 e tended 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.

3. WHAT ARE PELLETS?
Pellets are made by applying very high
pressure to sawdust; i.e. the residue of raw
timber (without paint) produced by sawmills,
carpentry works and other activities involved
in processing wood.
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 lignite, a natural
substance found in the wood itself.
As well as being an environmentally friendly
fuel, since wood residues are e ploited to the
ma imum, pellets also have technical
advantages.
While the heating power of wood is 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/m
3
and the
water content is 8% of its weight. For this
reason, pellets do not need to be seasoned
to obtain a sufficient heating yield.
Pellet diameters range from a minimum of 5
mm to a ma imum of 8 mm, though
E traflame recommends using 6 mm pellets.
3.1 Pellet storage
To guarantee problem-free combustion, the
pellets must be stored in a dry place.
WARNING
THE USE OF POOR QUALITY PELLETS OR ANY
OTHER MATERIAL MAY DAMAGE THE YOUR
STOVE AND MAY LEAD TO THE INVALIDATION
OF THE WARRANTY
AND THE RELATED RESPONSIBILITIES
OF THE MANUFACTURER.

5.2.1 Connection to t e ex aust venting system
Ex aust c annel or pipe
For the assembly of the e haust channels it is imperative to use non-flammable materials that are
resistant to combustion products and any condensates.
It is forbidden to use fle ible metal pipes and asbestos cement for connecting the stove to the
flue, also for pre-e isting e haust channels.
There must be continuity between the e haust channel and the flue so that the flue does not lean
on the stove.
The e haust channels must not pass through rooms in which the installation of combustion devices
is forbidden.
The assembly of the e haust channels 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 e haust outlets have to be reached that are not coa ial in relation to the
e haust 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 e haust fan, i.e. all products made by
E traflame, 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 meters.
•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, e haust channels 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 e haust channel must allow soot recovery and cleaning using a swab.
The e haust channel must have a constant cross-section. Any changes in cross-section are allowed
only at the flue connection.

5.2.5 Connection to external air intakes
To ensure correct operation, the appliance must have sufficient air available by means of e ternal
air intakes, 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. (E traflame 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., that are directly e posed to the radiance of the hearth must be placed at a safe distance.
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.
