3.12 CONNECTION IN PRESENCE OF ANOTHER HEAT GENERATOR
The thermal cooker may be easily matched also
to another heat generator. It is recommended to
contact a technician or an experienced installer in
order to plan a duly system. It is necessary to mind
that the thermal cooker must have the precedence
on every other heat generator, because when us-
ing solid combustible it is not technically possible
to break up immediately the combustion if neces-
3.13 CALCAREOUS WATER
Hard water with high residual saturation may cre-
ate deposits inside the water circuits. The contin-
uous use in these conditions may damage the de-
vice. In these cases, it is recommended to install a
softener upstream the entrance of the water inside
the thermal cooker, to be chosen according to the
features of water.
3.14 SACRIFICIAL ANODE
Inside the tank, there is a magnesium sacrifi-
cial anode, which prevents the corrosion due to
electro-chemical reactions or wandering currents
inside the boiler. When this happens the anode
corrodes itself to save the material with whom
the boiler is covered. The sacrificial anode must

sary. This can be managed manually but it can also
be automatic, using the advanced features of the
control unit of the thermal cooker.
With the correct electric connections, the control
unit can manage the working of the other heat
generator for both heating and production of san-
itary hot water.
After an extended use of the device, it could be
necessary to make the maintenance of the serpen-
tines when showing calcareous deposits on their
surfaces. In this case it is suggested to empty the
system, removing the serpentines and to proceed
to the mechanical cleaning of them.
be controlled at least once a year and must be re-
placed when the diameter is shorter than 10 mm.
The anode is just screwed on his support and the
replacement is easy and fast. It is recommended to
pay attention that the anode is not in contact with
the exchange serpentines.
Ask always a thermal technician for an installation
that best suites your needs.
