Before starting to use the cooker, remove
the packaging materials in the oven and in
the wood box, remove the stickers and re-
move the plastic film in which is wrapped
the plate and remove with a rag the most
of the oil on its surface. We suggest to make
a first lighting of the cooker just to verify the correct installation. The first lighting
must be done with moderate fire, using lit-
tle wood broken in small pieces. In the next
lightings you can progressively increase the
load of combustible.
The refractory mortar used for the internal
walling contains always a little moisture
that is eliminated after the first periods of
use: so it is normal that the first times you
light the cooker a little condensation is be-
ing generated.
All the refractory materials inside the cooker
experience a settlement process that may
generate small holes on the bricks, such holes do not preclude anyway the working
of the cooker.
Other settlements may involve other parts
of the cooker so during the heating and
cooling phases you might hear light noises.
These symptoms do not absolutely preclude
the use of the cooker and fading out till
disappearance with the constant use of the
cooker.

During the working, inside the cooker hap-
pens a combustive reaction of combusti-
ble (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 combustion: after the lighting,
the combustion goes on till the exhaustion
of the combustible but it can be maintained
lighted by making another load of combus-
tible 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 cham-
ber happens in different 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
feedings 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 post-combustion of the fumes,
generating further heating, knocking down
the amount of harmful gas and so improv-
ing both the rendering and the impact on
the environment. Once started the combus-
tion it cannot be interrupted in a safe way: it
must be always faded out naturally with the
exhaustion of all the combustible inserted.
