(*) 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 raw and enamelled meltings of cast iron.
The hearth is totally sheathed with single cast-iron sheets. Its back is extractable. Thanks to calibrated holes, made on the same back, it is
guaranteed a supply of pre-heated air inside the hearth, thus obtaining a post-combustion which increases the efficiency and reduces the
emission of the unburnt gases. Inside it there is a turning and extractable grate. Below the hearth door will be found an extractable ash-drawer
with a closing door (Picture 8 -
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 (see
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.
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).
ACCEssORIEs
The openings for the combustion air (primary and secondary) are managed by one single register.
sINgLE register PRIMARY air and sECONDARY air
The lever to adjust the combustion air is located underneath the fire-door
With the air register located under the door of the hearth, it is possible to adjust the air flow through the ash drawer and the grating in
direction of the fuel.
The air is necessary for the combustion process during the ignition. The air also keeps the flame alive.
The ash drawer has to be emptied regularly, so that ash cannot hinder the intake of air for the combustion. The air is also necessary to keep
fire live.
