(*) The proposed value are indicative. The installation must, in any case, be sized and verified according to the general calculation method in UNI
EN13384-1 or by another method of proven efficiency.
(**) For those buildings in which the thermal insulation does not correspond to the instructions on heat protection, the heating volume of the
product is: favourable type of building (30 kcal/h x m

With thermal insulation in accordance with the regulations regarding energy saving, the heated volume is greater. With temporary heating, in
the event of interruptions which last more than 8 hours, the heating capacity is reduced by about 25%.
The declared technical data have been achieved by burning beech wood class "A1" according to the requirement UNI EN ISO 17225-5 and wood
moisture content less than 20%. By burning a different kind of wood the efficiency of the product itself could change and some specific adjustments
on the appliance could be needed.

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 stone tiles. The
hearth is totally sheathed with cast-iron single sheets and refractory material (NORDIKER). 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 made of vermiculite, 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 hearth is equipped with a panoramic door with ceramic glass (resistant up to 700 °C). This allows a wonderful view on the burning flames.
Furthermore, it is thus avoided the output of sparks and smoke.
Below the hearth door will be found an extractable ash-drawer with a closing door
ACCESSORIES
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 (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 (Picture
With the air register located under the door of the hearth (on the left), it is possible to adjust the air flow through the ash drawer and the
grating in direction of the fuel. The primary air is necessary for the combustion process during the ignition. In order to open the passage
of primary air the lever should be completely pulled. The ash drawer has to be emptied regularly, so that ash cannot hinder the intake of
primary air for the combustion. Primary air is also necessary to keep fire live.
During the combustion of wood, the primary air register must be opened only a few, since otherwise the wood burns quickly and the device
can overheat (see chapter NORMAL OPERATION).
