BEAM PROTECTIONs

Considering the irradiation of the hearth, it is necessary to be particularly careful in protecting the beams while designing your stack. Consider
the proximity of beams to the external surfaces of the hearth, on one side, and the irradiation of the glass door, usually very close to the beams,
on the other side. In any case, it has to be considered that the internal or lower surfaces of this beam in flammable material must not come in
contact with temperatures higher than 65 °C.
WARNINg: We cannot be made liable for a wrong operation of the plant, when it does not comply with the provisions of
these instructions or when it uses additional products not suitable for this device.

TECHNICAL DEsCRIPTION

Definition: product according to EN 13229 The appliance works as an intermittent operating appliance.
The devices La Nordica are suitable to heat living spaces for some periods. As fuel, wood logs are used. .
The appliance is made up of a series of cast-iron elements joined to one another by a fixed joint, while the seal is assured by refractory putty.
The assembly is supported by tie rods and nuts located outside the heating body.
The devices are equipped with an integrated air circuit for the recovery of the heat made up of deflectors (radiant fins) on all external surfaces
of the heating body.
The devices are equipped with a hearth with double thickness rear part made up of a drilled extractible plate.
Through these holes, pre-heated air gets into the hearth; in this way, it is possible to achieve a post-combustion with an increase of the yield
and a reduction of emissions of unburnt gases.
The fireplace is equipped with a sight door with ceramic glass (resistant up to 700°C). This allows a charming sight on burning flames. Moreover,
in this way, any possible leak of sparks and smoke is avoided.
ACCEssORIEs
Room heating takes place:
a) By irradiation: through the panoramic glass and the external hot surfaces of the stove, the heat is radiated into the environment;
b) By natural convection: the passage of air through the coating and the covering hood releases heat in the room.
The device is equipped with registers of primary and secondary air.
1A- PRIMARY air register (Picture
With the primary air control 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 chapter NORMAL OPERATION).
2A - sECONDARY air register
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 un-burnt carbon does not undergo a post-combustion. See chapter NORMAL OPERATION. Through this
register it is possible to adjust the power of the device.
Leaving it slightly open, according to the flue of the device, it is possible to keep the glass clean.
The adjustment of the registers necessary to reach the rated calorific yield is the following one:
