La Nordica MONOBLOCCO GHISA 750 Manual Del Usuario página 25

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 device is made up of metal sheet plates in painted steel, castings of cast iron and refractory materials.
The hearth is coated by cast iron castings or nordiker ®, the grate holder and the related extractible grating are both made of cast iron.
The combusTion chamber assembly is air-TighT by welding and covered wiTh a galvanized sheeT meTal carTer.
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 sight door is assembled on extensible ball guides, which assure a robust and silent operation reliable in time.
The door lifting counter-weight is supported by two sturdy chains with related pinions.
The ceramic glass (resistant up to 700 °c) of the door allows a charming view on burning flames and avoids any leak of sparks and smoke.
under The hearTh graTing There is a easily exTracTable ash drawer, also when The appliance works.
aCCESSORIES
The heaTing of The room occurs:
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 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 primary air is necessary for the combustion process. in order to open the passage of primary air the lever should
be completely pulled. The ash drawer has to be emptied regularly, so that ash cannot hinder the intake of primary air for the combustion.
primary air is also necessary to keep fire live.
during The combusTion of wood, The primary air regisTer musT be opened only a few, since oTherwise The wood
burns quickly and The device can overheaT (see chapter normal operaTion).
2a - SECONDaRY air register
under the door of the hearth there is a secondary air register.
This register must be opened (and therefore the lever completely pushed), 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).
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:

The producT has been designed and builT Taking inTo consideraTion The normal
Thermal deformaTions of each single componenT due To The differenT TemperaTures
some parTs are subjecT To specific movemenTs which are necessary To guaranTee a
normal compensaTion of The Thermal deformaTions. Therefore, shall some movemenTs
or limiTed misalignmenTs of movable parTs be presenT or canTilevered iTems, These
have To be undersTood as normal and foreseen by The projecT.
