Technical Description; Flue - LA NORDICA INSERTO 80 WIDE Manuel Utilisateur

TECHNICAL DEsCRIPTION

The appliance La Nordica is suitable to heat living spaces for some periods. As fuel, wood logs are used. The appliance works as an
intermittent operating appliance.
The appliance is made up of a steel chamber completely soldered and hermetic.
The hearth is totally sheathed with single cast-iron sheets and refractory plates (NORDIKER). 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. 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.
Below the hearth door will be found an extractable ash-drawer with a closing door.
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 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.
With the lever totally PULLED OUT the sECONDARY airflow is CLOsED and the PRIMARY airflow is OPEN; with the lever totally IN the
PRIMARY airflow is CLOsED and the SECONDARY airflow is OPEN.
The adjustment of the registers necessary to reach the rated calorific yield is the following one:

It is possible to get the combustion air directly from outside through a flexible tube fireproof NOT furnished (see chapter VENTILATION
HOOD OR ADJACENT LOCAL).

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;
Should the flues have a square or rectangular section, internal edges must be rounded with a radius not lower than 20 mm. For the rectangular
section, the maximum ratio between the sides must be = 1.5.
A too small section causes a decrease of the draught. It is suggested a minimum height of 4 m.
The following features are FORBIDDEN and therefore they endanger the good operation of the device: asbestos cement, galvanized steel,
rough and porous internal surfaces. In
For a correct installation please respect the sections/lengths of the flue shown in the technical data table. By installations
with different dimensions the flue must be suitably sized in accordance with EN13384-1.
