• smoke ducts must not cross rooms where
the installation of combustion equipment is
prohibited.
In any case, the smoke ducts must be sealed
against combustion products and condensation,
as well as insulated if they lead outside of the
installation room.
Installing manual draught adjustment devices is
not allowed.
Creating an initial straight vertical smoke duct
section of at least 1 m to ensure proper smoke
ejection is mandatory.
5.2.2 Flue pipe
The flue pipe is a particularly important element
for correct appliance operation.
The flue pipe must be sized so as to guarantee
the draught declared by the Manufacturer.
Do not connect the appliance to a collective flue
pipe.
The flue pipe must be built applying the following
regulations:
• it must observe product standard EN 1856-1;
• it must be made of materials that are suitable
to
guarantee
mechanical, chemical and thermal stress and
be correctly thermally insulated to limit the
formation of condensation;
• it must be mainly vertical and not feature any
bottlenecks along its entire length;
• it must be correctly spaced with an air gap and
insulated from flammable materials;
• there must be a maximum of 2 changes in
direction and angles must not exceed 45°;
• the flue pipe inside the home, however, must
be insulated and can be inserted into a skylight
shaft, as long as it respects standards regarding
placing inside a tube;
• the smoke conduit must be connected to the
flue pipe using a "T" fitting with an inspection
collection chamber for combustion residue
and especially for collecting condensation.
It is necessary to check the safety distances that
need to be observed when there are flammable
materials and the type of insulating material that
needs to be used is on the flue pipe data plate.
Use watertight pipes with silicone seals.
It is forbidden to use the discharge mounted
directly on the wall or directed towards indoor
spaces and any other type of discharge that is not
set forth by the regulation in force in the country
of installation (Note: in Italy only roof-discharge
is allowed).
5.2.3 Chimney pot
The chimney pot, i.e. the top end of the flue pipe,
must fulfil the following characteristics:
• the cross-section of the smoke outlet must be
at least twice the internal cross-section of the
fireplace;
• it must stop water or snow from getting in;
• make sure the smoke is taken away even when
there is wind (wind resistant chimney pot);
• the outlet height must be outside of the reflux
zone (refer to national and local regulations to
calculate the reflux zone);
• it must always be built at a distance from
antennas or dishes, it must never be used as
support.

5.3 FIRE PREVENTION MEASURES
Every use of the appliance has a certain element of
danger in it. Therefore, the following instructions
must be carefully followed:
• Wait for the fire to die out. Never extinguish
flames with water.
• Lit appliance becomes hot and can cause
burns if touched.
• Remove ash only when the appliance is cold.
The ash may contain hot embers, so it must be
placed in a fireproof container.
• The ash must be placed outside or emptied in
a place where it will not pose a potential fire
hazard.
5.3.1 Flue pipe fire
• Close all openings and air intakes.
• Keep the appliance door closed.
• Call the fire brigade.
• Before the appliance and flue pipe are used
again after a fire, they must be checked by a
specialist technician to ensure that they are
undamaged and function correctly.
5.4 MINIMUM DISTANCE FROM
FLAMMABLE MATERIALS
The minimum safety distances when using the
appliance are given in the "Minimum safety
distances" sheet.
Objects and parts that are heat-sensitive or
flammable cannot be stored near the stove;
in any case keep these objects at a minimum
frontal distance of 100 cm from the most external
point of the appliance's footprint.
5.4.1 Requirements for the installation
premises
The
appliance
sufficiently ventilated. To fulfil this requisite it is
necessary to equip the room with an air intake
connected to the outdoors.
The installation room must have an air intake
with a free cross-section of at least 100 cm
For installation in the presence of other
combustion appliances or VMC system it is
necessary to check the appliance for correct
operation.
The appliance must never be installed outdoors.
It must be placed inside living spaces, but
cannot be installed in bathrooms or bedrooms
and explosive environments unless an airtight
installation is made. The volume of the room
where it is installed must be suitable for the
power of the appliance and, in any case, more
than 15 m
.

When extraction fans (example: extraction
hoods) are used in the same room or space as the
appliance, this can cause problems to appliance
operation.
The appliance must be installed on a floor with
suitable load capacity. If the existing position
does not fulfil this requirement, it is necessary
to take due measures (for example, using a load
distribution plate).
