LA NORDICA MARLENA 5.0 Manuel Utilisateur page 25

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.
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 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.
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).
The ADjuSTmENT Of THE REgISTERS necessary to reach THE RATED CALORIfIC yIELD is the following one:
mARLENA 5.0
LIÙ 5.0
LIÙ 5.0 PETRA
To ignite the flame follow the instructions below (see Cap. IGNITION) :
• Open the Primary and Secondary air control
• any butterfly valve placed on the flue gas exhaust pipe must also be opened.
