3.4 SAFETY
On every solid combustible based boilers it is not technically possible to break the
combustion immediately as happens for boilers based on liquid or gas combusti-
ble according to necessity. For this reason, it is important 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 danger of explosion of the boiler and serious in-
jury risk for the people present near the thermal stove. We suggest also to insert
in the system also a boiler able to accumulate the heating in excess produced by
the stove and not used as by the heating system.
3.5 THERMAL DISCHARGE
For more safety, it is possible to make an auxiliary circuit of thermal discharge
connected directly to the boiler. The thermal stove has a predisposition for this
solution. The thermal discharge system allows to cool directly 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.
All the components of the thermal discharge system external to the thermal stove
must be obtained by third parts according to the specifies of designer and install-
er. To make this system it is necessary to make the going and return connections,
that are interchangeable, 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 safe-
ty devices must be accessible also after the installing for the maintenance 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. All the components of the thermal discharge system
external to the thermal stove must be acquired by third parts. For the thermal
discharge valve we suggest to use the model 3065 of company SYR.
