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.
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
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
B1). 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:
