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 and refractory material plates, 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.

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.
aCCESSORIES
MonoBLocco 800
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
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.
• for the 800 model, the bar must be completely pulled out .
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
secondary air, passing in the façade's two side struts, heats up and triggers double combustion while also cleaning the glass
door (turn the regulator fully to the right). if you move the lever to the centre, the appliance (800 model) operates at a reduced
rate: primary air is closed and the flow of secondary air is halved (see chapter norMaL operation).
IT IS POSSIblE TO gET ThE aIR SECONDaRy DIRECTly fROm OuTSIDE through a fLexiBLe tuBe
(fireproof not furnisheD see chapter ventiLation anD aeration of the instaLLation preMises).
ThE aDjuSTmENT Of ThE REgISTERS necessary to reach the RaTED CalORIfIC yIElD is the following one:
