direction and angles must not exceed 45°;
• the chimney 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
chimney 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 chimney 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).
6.2.3 Chimney pot
The chimney pot, i.e. the top end of the chimney,
must fulfil the following characteristics:
• the cross-section of the smoke outlet must be
at least twice the internal cross-section of the
chimney;
• 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.
6.3 INSTALLATION
For appliance installation and use it is necessary
to observe all of the local, national and European
laws and regulations.
Appliance installation and the preparation of the
building work must observe the regulation in
force in the country of installation (ITALY = UNI
10683).
The installation activities must be carried out by
a technician that is qualified and/or authorised
by the Manufacturer. The staff in charge of
installation must issue a declaration of conformity
of the system to the buyer, whereby they take full
responsibility for the final installation and good
operation of the installed product.
There shall be no liability on the part of Ravelli if
these precautions are not observed.
6.3.1 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 80 cm
case of boiler.
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 be placed inside living
installation room must
quarters. It must never be installed outdoors. The
volume of the room where it is installed must be
suitable for the power of the appliance and, in
any case, greater 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).
Provide due insulation if the surface is made of
flammable material.
If the side walls adjacent to the appliance are
made of a flammable material, it will be necessary
to position the appliance at least 30 cm from
them.
If the floor that the appliance is standing on
is flammable, we recommend duly insulating
it. Objects and parts that are heat-sensitive or
flammable cannot be stored near the appliance;
in any case, keep such objects outside the area
bounded by the minimum distances indicated
above.
Appliance installation must guarantee easy
access to clean the appliance, the exhaust ducts
and the chimney.
6.3.2 Installation example
This type of installation (Fig. 6.1) requires an
insulated chimney pot, even if the entire
conduit is installed inside the building. Besides,
the structure must be inserted into a properly
ventilated skylight shaft.
In the lower part of the chimney pot there is an
inspection cover, properly isolated from wind
and rain.
