The boiler is fitted with a safety temperature limiter STB factory set to
90°C. If the set temperature is exceeded, the STB stops the burner
and the fuel feeder operation and an alarm message is displayed.
Check and remove the cause for boiler overheating. Allow the boiler
to cool, remove the STB nut and press the button.
The boiler temperature sensor [5] and the STB [4] must be installed in
the boiler temperature sensor casing [6]. The sensors must be fixed
securely.
