HYDRAULIC SYSTEM

Certain concepts referring to the Italian UNI 10412-2 (2009) Standard are described in this chapter.
As previously described, when installing, all national, regional, provincial and town council Standards in force provided by the
country in which the appliance has been installed must be complied with.
TABLE OF DEVICES FOR CLOSED VESSEL SYSTEM, PRESENT AND NOT PRESENT IN THE PRODUCT
Safety valve
Pump control thermostat (managed by the water probe and board program)
Acoustic alarm activation thermostat
Water temperature indicator (display)
Pressure transducer with display
Acoustic alarm
Automatic circuit breater switch (managed by board program)
Pressure transducer with minimum and maximum pressure switch alarm
Water overheating automatic circuit breaker (blocking thermostat)
Circulation system (pump)
Expansion system
During installation of the stove it is MANDATORY to adjust the system with a manometer in order to display the water pressure.

INSTALLATION AND SAFETY DEVICES

The installation, relative system connections, commissioning and inspection of correct functioning must be carried out perfectly,
in total compliance with Standards in force, both national, regional and municipal, as well as these instructions.

According to the UNI 10412-2 (2009) Standard in force in Italy, the closed systems must have: safety valve, pump control
thermostat, acoustic alarm activation thermostat, temperature indicator, pressure indicator, acoustic alarm, regulation automatic
circuit breaker switch, automatic circuit breaker block switch (block thermostat), circulation system, expansion system, safety
dissipation system incorporated with the generator with thermal safety valve (self-activated), whenever the appliance does not
have a temperature self-adjustment system.

DISTANCES OF SAFETY DEVICES ACCORDING TO THE STANDARD

The temperature safety sensors must be in place on the machine at a distance no greater than 30 cm from the ow connection.
