5. TECHNICAL DESCRIPTION
Definition
: product according to
EN 13240. The appliance works as an intermittent operating appliance.
The chimney stoves of La Nordica are suitable to heat living spaces for some periods or to support an insufficient centralized heating
system. They are ideal for holiday apartments and weekend houses or as an auxiliary heating system during the whole year. As fuel, it is
possible to use wood logs. The chimney stove is made of raw and enamelled meltings of cast iron.
The hearth is internally sheathed with single sheets in cast iron and inside it there is a turning and extractable grate. The model GIULIETTA
x, VIOLETTA x, is provided with an internal side of the hearth, which is extractable and pierced. Thanks to the calibrated holes of that side,
a contribution of pre-heated air inside the hearth is guaranteed, obtaining a post-combustion, which increases the yield and reduces the
exhaust gases emissions.
The hearth is equipped with a panoramic door with ceramic glass (resistant up to 700 °C). This allows a wonderful view on the burning
flames and avoids any possible output of sparks and smoke.
The heating of the environment is made
by irradiation:
through the panoramic glass and the external hot surfaces of the stove, the heat is
radiated into the environment. The device is equipped with registers of primary and secondary air by which it is adjusted the combustion air.
PRIMARY Air register ( B Picture 6 at page 62 )
With the thermostat (ISETTA EVO, ISOTTA EVO, VIOLA EVO) or valve (GIULIETTA x, VIOLETTA x) placed on the back of the right side
of the stove, it is adjusted the passage of air through the ash drawer and the grate in the fuel direction. The primary air is necessary for
the combustion process. The ash drawer must be regularly emptied, so that the ash does not obstruct the primary air entry. Through
the primary air the fire is also kept alive.
During wood combustion, the register of primary air must be opened only for a while, because otherwise the wood burns fast and the
stove may overheat. For the correct arrangement (see paragraph NORMAL OPERATION).
SECONDARY Air register ( A Picture 6 at page 62 )
Over the door of the hearth there is the secondary air control.
This regulator must be open (the lever must be moved to the right), especially for wood combustion, so that unburnt carbon undergoes
a post-combustion (see chapter NORMAL OPERATION).
Through this register it is possible to adjust the power of the stove. Leaving it slightly open, according to the flue of the chimney, it is
possible to keep the glass clean.
IGNITION CONTROL ( C Picture 6 at page 62 )
Close - ; Open + , See chapter LIGHTING.
LIGHTING OPERATION :
Open the secondary air register (
A
), primary air register (
B
), open the ignition control (
C
), light up the fire.
After about 10 minutes, when the fire is lighted, close the thermostat ( B ) and the ignition control ( C ) and adjust the combustion course
with the controls ( A ). The openings for air (primary and secondary) must be opened together just a little (you must open the eventual
butterfly valve placed on the pipe of smokes exhaust). See chapter LIGHTING.
LOAD THE FUEL
:
Before opening the hearth door, open the ignition control (C) , load the fuel, close the door and after about 5 or 10 minutes close
the control (C). IMPORTANT : we suggest you to open the door very slowly, to avoid the exit of smokes.
The adjustment of the registers necessary to reach the rated calorific yield is the following one:

6. FLUE
Essential requirements for correct appliance operation:
• the internal section must preferably be circular;
• the appliance must be thermally insulated and impermeable and built with suitable materials which are resistant to heat, combustion
products and any condensation;
• there must be no narrowing and vertical passages with deviations must not be greater than 45°;
• if already used, it must be clean;
• the technical data from the instruction manual must be respected;
If the flues are of a square or rectangular section, the internal edges must be rounded with a radius of not less than 20 mm.
For the rectangular section, the maximum ratio between the sides must be ≤ 1.5.
