INSTRUCTIONS FOR USERS
10. TROUBLESHOOTING
Do not drain the whole system as lling up with water again causes unnecessary and harmful scale to build up inside the
boiler and the heating elements. If the boiler is not used during winter and is therefore exposed to the danger of frost, add
some specic anti-freeze to the water in the system (e.g.: propylene glycol coupled with corrosion and scale inhibitors). The
electronic boiler management system includes a “frost protection” function for the heating system which, when delivery
temperature falls below 5°C, operates the burner until a delivery temperature of 30°C is reached.
The frost protection function is enabled if:
* the boiler is electrically powered;
* the gas tap is open;
* the system is at the correct pressure;
* the boiler is not blocked.
