The heating system must be emptied as follows:
-
Turn off the boiler;
- Attach a hose pipe and open the drain valve;
- Empty the system at the lowest points (where present). When the heating system
is unused for an extended period of time, it is recommended that you add
antifreeze with an ethylene glycol base to the water in the
heating lines and radiators if the ambient temperature drops below 0°C during the
winter.
This makes repeated draining of the entire system unnecessary.

The outlet pressure of the gas cock is obtained by completely loosening the screw on the solenoid. The
maximum pressure of the gas to the burner will be equal to the nominal delivery pressure minus the
head loss within the gas valve. [1 mbar = 10,197 mmc.a.]

FROST DEVICE
:
The boiler is equipped with a device that, in the event of the water temperature
going below 6°C, the burner ignites at the minimum power until the boiler water
reaches a temperature of 16°C.
This device operates only if the boiler is functioning perfectly and:
- the system pressure is sufficient;
- the boiler is powered electrically - L.E.D.

HUTDOWN
:
The boiler is fitted with safety devices, which in the event of defective discharge
of exhaust fumes, automatically interrupts the gas supply, thereby shutting off
the boiler.
The shutdown of the boiler is temporary and when the discharge state of
exhaust fumes has returned to normal, the boiler automatically turns back on
