3 INSTALLATION
The assembly position must be chosen based on the
environment, the discharge and the chimney flue.
Check, with your local authority, if there are more
restrictive provisions regarding the oxidising air intake,
the smoke discharge system including the chimney
flue and chimney pot.
The manufacturer cannot be held in any way liable in
the event of installation non-compliant with legislation
in force, of incorrect premises air exchange or
electrical connection non-conforming with standards
and/or inappropriate use of the appliance.
Installation must be carried out by a qualified
technician, who will issue the purchaser with a
Declaration of Conformity for the system and will
assume complete responsibility for final installation
and resulting good operation of the product.
In particular, he should ascertain:
• there is an adequate oxidising air intake and good
smoke discharge compliant with the type of product
installed;
• other stoves or devices installed do not cause
negative pressure in the room where the product is
installed (only for hermetic appliances, a maximum
of 15 Pa depression in the surroundings is permitted);
• when the product is on, there is no smoke back
draught in the surroundings;
• smoke evacuation is implement in total safety
(dimensioning, smoke seal, distances from
flammable materials..).
Once the position is decided where to install the
product, you need to pay attention:
• if the floor is made of combustible material, you
should use protection in suitable material (steel,
glass...) which also protects the front part from any
falling burning fuel during cleaning operations:
• that the floor guarantees adequate load capacity
if the existing building does not meet this requirement,
you should take appropriate measures (for example
a load distribution plate).
3.1 AIR INTAKE
The installation premises of non-hermetic appliances
must be sufficiently ventilated with specific openings,
with particular attention on the position (they must
NEVER be blocked), which consent air reintegration in
the environment.
The air must be taken directly from outside (not from
other rooms, garage, etc.) and must have a net useful
section equal or higher than 80 cm
2
pellet burning
stoves and thermostoves (EN 14785) and 100 cm
2
for
boilers (EN 303-5).
The air intake is not necessary for installation of the
hermetic appliances that take air directly from
outside. Check and comply with the ventilation
requirements for simultaneous operations with other
combustion devices and in the presence of forced
ventilation systems or hoods (refer to section 6.4 of
UNI 10683).
3.2 SMOKE CHANNEL AND FITTINGS
The term smoke channel indicates the piping
connecting the appliance to combustion with the
chimney flue.
For heat generating appliances with an electric fan to
expel the smoke, the following installation instructions
must be followed, provided by the manufacturer
concerning the maximum length and number of
curves the smoke channels can have.
If no indications are given for maximum values or
deriving from preliminary calculations according
to UNI EN 13384-1, the following provisions must be
applied:
• comply with the product standard EN1856-2;
• the horizontal sections must have a minimum slope
of 3% upwards;
• the length of the horizontal section must be
minimal and its projection on plan must not exceed
4 metres;
• the number of changes of direction including
introduction in the chimney flue and excluding
that by effect of using a “T” element
in the appliances with rear smoke output, must
not exceed 3;
• the changes of direction must not have an angle
over 90°(45° curve recommended);
• the section must have a constant diameter
equal to the output of the fireplace up to the
fitting in the chimney flue;
• it is forbidden to use flexible metal and fibre cement
piping, furthermore the piping must guarantee
pressurised sealing;
• the smoke channels must not cross premises
in which installation is forbidden of combustion
appliances;
• Use watertight piping with silicone gaskets.
In any case, the smoke channels must be
sealed by combustion and condensate
products, as well as insulated if passing
inside the installation premises.
Assembly is not permitted of draught manual
adjustment devices on forced draught appliances.
You need to install a first vertical smoke channel
section of at least 1 metre to guarantee correct
smoke ejection.
All local and national legislation and European
standards must be met when installing and using the
the product.
