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.

DEsCRIPTION

The appliance is made up of a steel chamber completely soldered and hermetic. The hearth is coated by single castiron sheets and refractory
plates (IRONKER).
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 galvanized sheet carter.
Inside the hearth there are a grate holder and the related grating, both made of very thick cast-iron and easily extractable.
The appliances are equipped with an integrated air circuit for the recovery of the heat made up of a galvanized steel carter external to the
heating body. The appliance works as an intermittent operating appliance.
The fireplace is equipped with to sight door with ceramic glass (resistant up to 700°C). 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 (B) there is a easily extractable
ash drawer (A), 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 (on the left), 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 during the ignition. 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 (on the right) there is a secondary air register.
This valve must be opened (and therefore 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 air sECONDARY directly from outside through a flexible tube (fireproof NOT furnished
It is necessary to remove the underlying semi-blanks. (see Ref 1 or 2).
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;
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.
