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.
