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 and coated with a carter made of varnished and galvanized
sheet heat-resistant.
The appliances 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 insert 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. Under the hearth grating there is a easily extractable ash drawer.

The heating of the room occurs:
by convection: the passage of air through the coating and the covering hood releases heat in the room.
a) by convection: the passage of air through the coating and the covering hood releases heat in the room.
b) by radiation: through the sight glass and the steel body, heat is radiated into the room.
The device is equipped with registers of primary and secondary air, with which it is possible to adjust the combustion air.
1A - PRIMARY air register
(Picture
With the primary air control, 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.
During wood combustion, the register of primary air must be opened only for a while, because otherwise the wood burns fast and the
insert may overheat(see chapter NORMAL OPERATION).
2A - sECONDARY air register
On the over part of the door there is the secondary air control. Also this register must be opened (then moved to the right), in detail, for
the combustion of wood, so that unburnt carbon can be subject to a post-combustion, increasing the yield and assuring the cleaning of
the glass (see chapter NORMAL OPERATION).
The adjustment of the registers necessary to reach the rated calorific yield is the following one:

FLUE

Essential requirements for a correct operation of the device:
• the internal section must be preferably circular;
• be thermally insulated and water-proof and produced with materials suitable to resist to heat, combustion products and
possible condensates;
• not be throttled and show a vertical arrangement with deviations not greater than 45°;
• if already used, it must be clean;
• all the sections of the flue gas duct must be accessible to inspection;
• inspection openings must be provided for cleaning.
• observe the technical data of the instructions manual;
Picture 2 gives some examples of execution.
