3.1 GENERAL NOTES
ST thermal cookers are endowed with boiler
to use the heating produced by the device
through a system with fluid vector for heat-
ing and for the production of hot water.
The system must be designed according to
UNI 10412-2:2006 law by a qualified thermal
technician and must be installed by experi-
enced people according to existing laws in
particular to UNI 10683:2005 law.
The thermal cookers are endowed with all
3.2 CONNECTIONS TO THE HEATING SYSTEM
Before the lighting of the thermal cooker
it is necessary to make the connections to
the heating system. The use of the thermal
cooker with empty or not connected to the
system boiler causes the irreversible damag-

AUXILIARY CONNECTIONS

According to the system you want to in-
stall, there are some auxiliary connectors
for facultative use, but sometimes necessary.
These are the connectors for the thermal di-
3.4 THERMOSTAT
ST thermal cookers are not endowed with
thermostat. If you want to create a forced
circulation based heating system it is neces-
sary to use an external thermostat to control
the working of the circulation pump of the
system, according to the temperature of the
water in the boiler. The thermostat detector
WARNING! For a longer duration of the boiler of the thermal cooker, you must
not make circulate the water with temperatures lower than 55-60° C. Lower tem-
peratures generate acid condensation and gas-black on the walls of the boiler.
