In order to guarantee correct absorption of the heat produced by the generator it is advisable to use a boiler tube with volume and
heat exchange capacity suitable for the power of the generator. The boiler tube must have a minimum capacity of 300l. In any case
the boiler tube must be capable of absorbing all the power that the generator is capable of delivering.
If this rule is not observed, the generator could raise the water temperature to such a point as to activate the safety limit thermostat
which stops the fuel from dropping into the burner and therefore forces the appliance to shut off.
The installer is required to install a valve that switches over to the system, powered by the stove’s control unit, which trips when the
boiler is thermally “satisfied ”. Consequently, the plant must be designed in such a way that the hot water produced by the generator
can reach the various rooms by acting on the zone valves.
ATTENTION: it is mandatory to earth the generator. If this instruction is not observed serious damage, which
is not covered by warranty, will result to the body of the appliance. Have a skilled electrician check the
earthing. There must be no electric potential (Volt) between the generator earth and the plant’s real earth
(earth plate). To prevent electrochemical corrosion of the appliance body do not use galvanised pipes and
fittings. Other materials must be earthed with special earthing cables in order to obtain a unipotential
earthing system.
