3.6 THERMAL DISCHARGE
3.7 EXAMPLES
The thermal discharge system allows to cool di-
rectly the boiler when it is necessary by making
flow cold leaking water in a separate circuit inside
the boiler. The making of the thermal discharge
system is under responsibility of the installer. To
make this auxiliary system it is necessary to make
the going and return connections, that are inter-
changeable, the detector that rules the device
must be inserted in the apposite connection bulb.
The system, to be effective, must be able to work
and must have availability of cold water also in
case of lack of AC power. The safety devices must
be accessible also after the installing for the main-
tenance and the functional verify. The functional
verify must be done regularly: we suggest at least
once a year. The thermal discharge circuit must
not be used for the production of hot water for
domestic use.
On demand, Rizzoli can give a thermal discharge
valve appropriate for the use with its thermos-
toves.
Here are some examples of possible system real-
ization. These schemes are just valid as example
and must not be used in the making of the system.
Ask always a thermal technician for an installation
that best suites your needs.
