5.ANTI-FROST DEVICE:
The boiler is equipped with a device that, in the event of the water temperature going below 5°C, the
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.
6 - EXHAUST DISCHARGE ANOMALY SHUTDOWN:
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.
7 - SAFETY SHUTDOWN:
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.
3.9 DRAINING THE SYSTEMDRAINING THE HEATING SYSTEM
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.
DRAINING THE DOMESTIC HOT WATER SYSTEM
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).
