The heating system must be emptied as follows:
- Turn off the boiler;
- Open the drain valve for the system and place a container below to catch the
water that comes out;
- Empty the system at the lowest points (where present). If you plan on not
using the heating system 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.

Whenever there is the danger of the temperature dropping below the freezing
point, the domestic hot water system must be drained as follows:
- Turn off the general water valve for the household plumbing system;
- Turn on all the hot and cold water taps;
- Empty the remaining water from the lowest points in the system (where
present).

FROST DEVICE
The boiler is equipped with a device that, in the event of the water
temperature going below 5°C, the 3-way diverter valve switches to
domestic hot water and the burner ignites at the minimum power until
the boiler water reaches a temperature of about 50°C.
This device operates only if the boiler is functioning perfectly and:
- the system pressure is sufficient;
- the boiler is powered electrically;
- the gas is distributed.

ISCHARGE
NOMALY
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 is indicated by the
illumination of the yellow L.E.D. "E" for a period of about 15 minutes.
Once this time period has passed and the discharge state of exhaust
fumes has returned to normal, the boiler automatically turns back on.

At the start of every lighting phase, the P.C.B. performs a series of
internal controls. If a malfunction occurs, the boiler will shutdown until
the problem has been resolved.
