The technical law (UNI 10412-2:2006) has in-
troduced the possibility to install the solid com
bustion based devices matched with devices with
closed expansion tank, endowed with thermal dis-
charge with emergency exchanger inside the
boiler. T Series thermostoves are endowed with all
the predispositions for the thermal discharge.
T Series thermostoves can be installed with open
expansion tank, in this case you should use the go-
ing connector to connect also the safety pipe and
the return connector also for the pipe of discharge.
The thermostoves may also be installed with
closed expansion tank making the thermal dis-
charge system and then connecting the connec-
tors as described forward.
T Series thermostoves are endowed with thermo-
stat to control the working of the pump. The ther-
mostat, or a control unit with the same function,
must be always used when there is a circulation
pump in the system.
The thermostat must be placed outside the device
with the temperature detector inserted in an ap-
propriate hole in the rear part of the thermostove.
The thermostat must guarantee that the pump
works when the boiler hot water temperature
overtakes the set temperature.
On every solid combustible based boilers it is not
technically possible to break the combustion im-
mediately as happens for boilers based on liquid
or gas combustible according to necessity. For
this reason, it is mandatory to swallow always the
produced heating also even if the heating system
does not request that and also in case of lack of AC
power. On contrary, the water in the boiler could
boil without possibility of outlet, with serious dan-
ger of explosion of the boiler and serious injury risk
for the people present near the thermostove. For
this reason, we recommend to follow strictly what
is written in UNI 10412-2 law in the various cases
and we suggest also to insert in the system also
a boiler able to accumulate the heating in excess
produced as sanitary hot water.
Before the lighting of the thermostove it is nec-
essary to make the connections to the heating
system. The use of the thermostove with empty
or not connected to the system boiler causes the
irreversible damaging of the boiler itself.
Anyway, it is necessary to connect the going con-
nector, the return connector and the discharge
connector (necessary to empty the boiler in case
of maintenance), the other connectors according
to the kind of system that you make could be not
necessary and so in this case you can cover them.
In some installations, for example on the wall, it is
suggested to predispose an apposite niche in cor-
respondence of the connections and to connect
the thermostove with flexible pipes.
3.3 INSTALLATION MODES
3.4 THERMOSTAT
3.5 SAFETY
WARNING! For a longer duration of the boiler of the thermostove, you must not make
circulate the water with temperatures lower than 55-60° C. Lower temperatures
generate acid condensation and gas-black on the walls of the boiler.
WARNING! The detector holder shall not be longer than 100 mm inside the boiler.
