The consumption of wood is subject to the quality and degree of dryness of the same

14
ASSEMBLY
Positioning
The initial phase for the best installation of the fireplace heating
system is to determine its optimal location; regarding this the
following data needs to be taken into account:
Possibility of creating an external air vent;
Possibility of creating a straight flue and possibly coaxial at
the fireplace heating system outlet;
Possibility of creating piping necessary to discharge
boiling;
Proximity to the main liquid collector and /or the boiler if
one already exists);
Proximity or ease of connection to the water system.
Once the best location for the appliance is determined, it is
possible to position the fireplace heating system following the
indications below.
The appliance must be installed on a floor with suitable load
capacity. If the existing building does not fulfil this requirement
appropriate measures (e.g. load distribution plate) must be
taken.
The minimum safety distance from inflammable materials must
be at least 300 mm from the fireplace heating system.
Appliance installation must guarantee easy access for cleaning
the appliance itself, the gas pipes and the flue.
The air extraction devices must not be used in the same room as
the appliance, unless an adequate ventilation air supply is
envisioned.

15
Air vent
Modern houses are all equipped with hermetic fittings, which do
not allow any air to pass.
To burn one Kg of wood about 15 m3 of air is required (in
fireplaces with closed hearth) and 40 m3 in fireplaces with open
hearth.
If the combustion of the wood inside the combustion chamber is
perfect, the amount of carbon dioxide (CO2) produced will be
equal to that absorbed by a living plant via the “chlorophyll
photosynthesis” process.
The lack of oxygen leads to bad and incomplete combustion,
which only makes partial use of the wood's energy and instead
of developing carbon dioxide (CO2) causes the formation of
carbon monoxide (CO), a highly toxic substance. Consequently
it heats less and pollutes more.
This is why fireplace absolutely require an external air vent.
To realise the air vent in the wall behind the fireplace heating
system, follow the indications given below:
IMPORTANT:
Make an external air vent respecting the following minimum
passages:
Solution A: 650 cm2(Ø 30 cm)
Solution B: 390 cm2(Ø 22 cm)
It is also mandatory to create a hood aeration grid "C" with
minimum passages, 390 cm2(Ø 22 cm), without filters or
closures;

N.B.: It is important that the grid communicates with the external
air vent without connection via pipes.
If it is not possible to realise the air vent in the wall behind the
fireplace heating system, make the hole in a perimeter wall where the
fireplace heating system is installed.
If it not possible to realise the external air vent in the same room
where the fireplace heating system is installed, this hole can be made
in an adjoining room as long as this room communicates
permanently, by means of a transit hole (20cm minimum diameter).
The UNI 10683 Standard PROHIBITS the withdrawal of
combustion air from garages, combustible material warehouses,
or from activities where there is a fire hazard.
If there are other heating or suction appliances in the room, air
vents must guarantee an air volume necessary for the proper
functioning of all devices.
Only sealed appliances (e.g. C type gas appliances, according to
the UNI 7129 Standard) or appliances that do not cause a lower
pressure compared with the external environment can pre-exist
or be installed in the place where the fireplace heating system
must be installed.
Extractor fans can cause functioning problems to the thermo stove when
they are installed in the same room or space where the fireplace heating
system is found.

17
Flue and connection to the same
The Flue is a fundamental component for correct functioning of the
fireplace heating system. The minimum section of the flue must be that
indicated in the fireplace heating system technical features (250 mm).
Each fireplace heating system must be equipped with its own flue,
without other intakes (boilers, fireplaces, stoves, etc…). Flue
dimensions are closely related to its height, which must be measured
from the fireplace heating system flue gas outlet to the chimney base.
In order to guarantee draught, the chimney flue outlet surface must be
twice as big as the flue section. The combustion products exhaust
pipe, generated by the natural draught appliance, must respond to the
following requisites:
Combustion products sealed, waterproof and suitably isolated
and insulated in the same way as the conditions of use (cf UNI
9615);
Realised with suitable materials in order to resist to normal
mechanical stress, heat, action of the combustion products
and in the event of condensation;
Upward alignment after the vertical tract throughout the
remaining pathway with 50% minimum gradient. The sub-
horizontal alignment part must not have a length greater than
¼ of the effective height of the flue or chimney and it must not
however be longer than 2,000 mm;
Preferably circular internal section: squared and rectangular
sections must have rounded angles with radius larger than 20
mm;
Constant, free and independent internal section;
Rectangular sections with 1:5 maximum ratio between the
sides;
If the flue is installed externally it is absolutely necessary
that it is insulated in order to avoid the flue gas cooling
and the formation of condensate;
For the assembly of the flue gas pipes (which go from the
appliance to the flue inlet) elements of non-combustible
material must be used, which are suitable for resisting
combustion products and their condensation;
It is forbidden to utilise fibre cement pipes to connect the
appliances to the flue;

18
Flue pipes must not pass through places in which the
installation of combustion appliances is forbidden;
The assembly of flue pipes must be performed in a way to
guarantee the sealing against flue gas for the appliance
functioning conditions in low pressure;
The assembly of horizontal tracts is prohibited, unless
absolutely necessary;
It is forbidden to use tilted elements;
The flue gas pipe must allow the recovery of soot or be
cleanable and must have a constant section;
It is prohibited to make other air intake channels and pipes, for
plant engineering, transit inside the flue gas pipes, even if
over-dimensioned.

19
Chimney
The chimney is a device crowning the flue, used to ease dispersion of
combustion products.
It must satisfy the following requisites:
Have a useful outlet section that is not less than the double
of that of the flue on which it is inserted;
Be conformed in a way to prevent the penetration of rain
and snow into the flue;
Be built in a way that, also in the case of winds from every
direction and inclination, to ensure combustion exhaust.
The outlet height (where height means that which corresponds to the
top of the flue, independently of any chimneys) must be outside of the
so-called reflow zone in order to prevent the formation of counter-
pressures, which prevent free exhaust of the combustion products into
the atmosphere.
It is therefore necessary that the minimum heights, indicated in the
following figures, are respected:
Technical
volume

0,5 m
Distance > 5 m Distance < 5 m Distance> 1,85 m
Distance< 1,85 m

CONNECTIONS
Electrical connection
The electric connection must only be performed by qualified
staff, with respect to general and local Safety Standards in
force.
Check that the power supply voltage and frequency
correspond to 220 V –50 Hz.
Appliance safety is obtained when the same is correctly
connected to an efficient earth plant.
In the electric connection to the mains power supply, envision a 6
A –Id 30 mA differential magnet circuit breaker switch with
relevant breaking load. The electric connections, including the
earth, must be made after the voltage has been removed from
the electric plant. When realising the system remember that the
cables must be placed in an unmovable and away from parts
subject to high temperatures. During the final wiring of the circuit,
only use components with a suitable electric protection rating.
KLOVER srl declines all responsibility for injury to persons,
animals or damage to objects deriving from the failure to
connect the network to the fireplace heating system earth
plant and failure to comply with the IEC Standards.
