1.4 Safety devices for closed expansion tank system
Systems with closed expansion tank must be tted with:
• Safety valve
• Circulator control thermostat
• Acoustic alarm activation thermostat
• Temperature gauge
• Pressure gauge
• Acoustic alarm
• Automatic thermal regulation switch
• Automatic thermal blockage switch (blockage thermostat)
• Circulation system
• Expansion system (the expansion vessel on the re is sufcient for the re. An extra
vessel may be required depending on the total water volume)
• Safety dissipation system incorporated in the generator with thermal discharge valve
(self-operated), if the device is not tted with a temperature self-regulator.
Automatic lling domestic-type heating devices must be tted with a fuel-blocking thermostat or with
a cooling circuit set by the device’s manufacturer, activated by a thermal safety valve that guarantees
that the highest temperature established by law is not exceeded. The connection between the supply
unit and the valve must be with cut-off devices. The pressure up-stream from the cooling circuit must
be at least 1.5 bars.
Installation recommendations
Warning: Our thermal stoves are tted with 3-litre (Genova, Pisa) and 6-litre (Venezia, Amal ) expansion
tanks. For thermal stoves with a 3-litre expansion tank a further expansion tank with a capacity of at
least 15 litres must be installed in the circuit.
Stoves with a 6-litre expansion tank do not need a further expansion tank if the plant has a maximum
capacity of 60 litres of water; otherwise, in this case also an expansion tank with a capacity of at least
10 litres must be installed.
