BOILER FROST PROTECTION
The appliance has a built in frost protection device that protects the boiler from freezing. With the gas and
electric supplies ON and irrespective of any room thermostat setting, the frost protection device will
operate the pump when the temperature fallsbelow 10°C and will operate the burner when the temperature
falls below 5°C. The burner will switch off when the temperature reaches 27°C. When the frost protection
device operates “AF” is displayed on the digital display.
IMPORTANT NOTE:
The system should be protected by incorporating a system frost thermostat.
