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 burn-
ing (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 light-
ing, 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
WARNING! For the correct working of the wood fired cooker, verify that the comburent
air flow through the intake of the cooker, the eventual air intake in the room and all the
aeration and ventilation grills are not obstructed.
3.2 STARTING
To allow an easier lighting of the cooker with cold
chimney, the M-MZ-ML Range wood fired cookers
have two devices useful for starting. The starting
key is ruled by a rod: extracting the rod, the key
opens. This creates a direct connection between
the combustion chamber and the chimney, in or-
der to obtain an improved draught.
The regulation of starting primary air allows the

inside the combustion chamber happens in differ-
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 environment. Once started the com-

haustion of all the combustible inserted.
direct entrance of air from the room in which the
cooker is installed to the combustion chamber.
When starting, it is suggested to open both the
devices that later shall be closed when the fire will
be started for the normal working of the cooker.
The cooker is designed to be used with the start-
ing regulations closed, using they in different ways
