3.1 WORKING OF THE COOKER
During the working, inside the cooker happens
a combustive reaction of combustible (the wood
inserted in the combustion chamber) and burning
(the oxygen present in the air of the room in which
the cooker is placed).
The wood fired cooker makes an intermittent com-
bustion: after the lighting, the combustion goes on
till the exhaustion of the combustible but it can
be maintained lighted by making another load of
combustible and so on.
The maintenance of the combustion in time is
guaranteed by the correct working of the chimney,
which allows to evacuate the fumes and in the
same time to feed the flame with comburent air.
In this way, the features of the chimney have a big
influence on the correct working of the cooker.
The combustion of wood requests that the air flow
inside the combustion chamber happens in differ-
WARNING! For the correct working of the wood fired cooker verify that the passage of
comburent air is not obstructed or, in case of connection with external air intake, that the
air aspiration grill is not obstructed.
3.2 STARTING
To allow an easier lighting of the cooker with cold
chimney, the wood fired cookers have two devices
useful for starting. The starting key is ruled by a
rod: extracting the rod, the key opens. This cre-

ent points to obtain the maximum efficiency. In
particular, it is present a primary air feeding that
flows in the lower part of the combustion chamber
by the grill, and one or more secondary air feed-
ings that flow in the upper part of the combustion
chamber.
The primary air is the main air and regulates the
combustion speed.
The secondary air allows the post­combustion of
the fumes, generating further heating, knocking
down the amount of harmful gas and so improving
both the rendering and the impact on the environ-
ment.
Once started the combustion it cannot be inter-
rupted in a safe way: it must be always faded out
naturally with the exhaustion of all the combus-
tible inserted.
ates a direct connection between the combustion
chamber and the chimney, in order to obtain an
improved draught.
