(*) 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 steel, enamelled cast iron and thermo radiant ceramic.
The hearth is internally sheathed with single sheets in cast iron and inside it there is a turning and extractable grate; the back side is extractable.
Thanks to some calibrated holes made over that side, the supply of pre-heated air inside hearth is guaranteed and having, in this way, a post-
combustion which increases the yield and reduces gas output. Inside it there is a turning and extractable grate.
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 dowor
The heating of the environment is made by:
• Convection: (70%) the air passage through the double mantel of the stove releases heat into the environment;
• 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 (Picture 6
With the primary air control (movable valve), which is found below the hearth door 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.
