INSTALLATION MODES
The technical law (UNI 10412-2:2006) has intro-
duced the possibility to install the solid combus-
tion based devices matched with devices with
closed expansion tank, endowed with thermal dis-
charge with emergency exchanger inside the boil-
er. RTE - RTVE thermal cookers are endowed with
all the predispositions for the thermal discharge.
RTE – RTVE thermal cookers can be installed with
3.5
THERMOSTAT
RTE - RTVE thermal cookers are endowed with
thermostat to control the working of the pump.
The thermostat, or a control unit with the same
function, must be always used when there is a cir-
culation pump in the system.
The thermostat must be placed outside the device

open expansion tank, in this case you should use
the going connector to connect also the safety
pipe and the return connector also for the pipe of
discharge.
RTE - RTVE thermal cookers may also be installed
with closed expansion tank making the thermal
discharge system and then connecting the con-
nectors as described forward.
with the temperature detector inserted in an ap-
propriate hole in the rear part of the thermal cook-
er. The thermostat must guarantee that the pump
works when the boiler hot water temperature
overtakes the set temperature.
