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.

for the normal working
To allow an easier lighting of the cooker
with cold chimney, wood fired cookers are
endowed with starting key governed by a
rod: if you extract this rod, the key opens.
The opening of the key creates a direct con-
nection between the combustion chamber
and the chimney, in order to obtain a better
draught. To light the fire, you can use well
dried wood, very subtly cut, together with
the specific products you can find in com-
merce. The combustion may be difficult as
long as the chimney is cold. The necessary time depends on the chimney and on the
weather conditions. When the fire becomes
powerful you must turn off the key in order
to force the fume to heat the other parts of
the cooker. The cooker is designed to work
with the key turned off, the use with the key
opened does not allow the cooker to work
at its best and may cause overheating and
consequent damages.
3.2 STARTING
The primary air regulator, located in the
front of the cooker, is ruled by a graduate
hand grip which regulates the combustion
speed. Low values ensure less power and
bigger autonomy. High values ensure more
power and less autonomy. The regulator is
automatic and maintains steady the heating
produced by the cooker.
The secondary air is set automatically ac- cording to the settings of primary air and to
the conditions of working and draught.
When the cooker is not working, the pri-
mary air regulator must be set to 0, in or-
der to limit the undesired air flow that may
cause an anticipated cooling of the device
and the room. This operation is particularly
important when the external air intake of
the cooker is directly connected.
