TECHNICAL DESCRIPTION

The chimney stoves of La Nordica are suitable to heat living spaces for some periods. As fuel, wood logs are used. The appliance
works as an intermittent operating appliance.
The stove is made of sheets in galvanized and painted steel, of cast iron (grate and grate holder of the hearth, exhaust pipe) of
majolica tiles and of glass panels. The hearth is totally sheathed with cast-iron single sheets and refractory material (IRONKER).
Inside there are a easy extractable thick flat grate and its holder. The combustion chamber is hermetic welded and is sheathed with
a painted steel carter.
The inside smoke plate, reflects the fire radiation and increases the internal temperature of the combustion chamber. This process
together with the exhaust gases flows, makes optimal the combustion and improves the efficiency.
The one-piece ceramic glass of the door (resistant up to 700 °C) allows a wonderful view on the burning flames. Furthermore, it is
thus avoided the output of sparks and smoke.
Below the hearth grate there is an extractable ash drawer,
ACCESSORIES
The heating of the environment is made by:
a) Convection : (70%) the air passage through the double mantel of the stove releases heat into the environment;
b) Irradiation : (30%) through the panoramic glass and the external hot surfaces of the stove, the heat is radiated into the
environment. (See chapter CALCULATION OF THE THERMAL POWER).
The stove is equipped with controls of primary and secondary air by which it is adjusted the combustion air.
1A - PRIMARY AIR register (right lever)
Below the hearth door, on the front right side, there is the primary air register, in the style of lever
With this air register, it is adjusted the passage of primary air into the low part of the stove and through particular channels flows
in the fuel direction. The primary air is necessary for the combustion process during lighting. The ash drawer must be regularly
emptied, so that the ash does not obstruct the entry of the primary air for the combustion. In order to open the air flow, the bar
must be completely pulled out. During wood combustion, the register of primary air must be opened only for a while, because
otherwise the wood burns too fast and the stove may overheat (see chapter NORMAL OPERATION).
2A - SECONDARY AIR register (left lever)
Below the hearth door, on the left front side there is the secondary air register
The secondary air, passing through the two lateral jambs of the front side, heats itself starting the double combustion and
keeping at the same time the glass clean (with open register).
When the bar is pushed to the back the passage of the secondary is completely open (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.
The adjustment of the registers necessary to reach the rated calorific yield is the following one:

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.
A section which is too small causes a reduction in draught. A minimum height of 4 m is advisable.
