FIRsT-AID MEAsUREs

Should any fire arise in the stack or in the flue:
a) Close the feeding door.
b) Close the registers of combustion air
c) Extinguish the fire using carbon dioxide fire-fighting means (CO
d) Seek immediate intervention of FIRE BRIGADE.
DO NOT ExTINgUIsH FIRE UsINg WATER JETs. When the flue does not burn any more please arrange an examination by a specialist in order
to find possible cracks and permeable points.

BEAM PROTECTIONs

Considering the irradiation of the hearth, it is necessary to be particularly careful in protecting the beams while designing your stack. Consider
the proximity of beams to the external surfaces of the hearth, on one side, and the irradiation of the glass door, usually very close to the beams,
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.

TECHNICAL 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 (NORDIKER).
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). One 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
(Picture 13 - A).
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.
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:
