DESCRIPTION

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 (optional).
The devices are equipped with an integrated air circuit for the
recovery of the heat made up of deflectors (radiant fins) on all
external surfaces of the heating body.
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
The fireplace is equipped with a sight door with ceramic glass
(resistant up to 700° C).
This allows a charming sight on burning flames. Moreover, in this
way, any possible leak of sparks and smoke is avoided.
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.
1) 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.
1- PRIMARY air register (Picture 1)
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.
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.
2- SECONDARY air register (Picture 1)
Under the door of the hearth (on the right) there is a secondary air
register.
This valve must be opened (and therefore shifted to the right), 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 CHAP. 13).
It is possible to get the air directly from outside through a flexible
tube (fireproof) (See Picture 2 Ref C).
