5.1 F / E
IRING UP XTINGUISHING
After the initial ignition of the boiler, the Ignition function must be activated. In this mode, the fan will start working to facilitate
ignition (in a still cold boiler). Once the CH temperature rises to 30°C (the so-called fan threshold), the Fan On/ Off function will
appear on the display instead of the Ignition option and the Manual Operation diode will turn off and the boiler will enter the
operating mode. Using the Fan On/ Off function, the fan can be switched on or off (e.g. when adding fuel). Turning off the fan is
indicated by an asterisk on the main screen in the lower right corner of the display. This function allows for safe operation of the
boiler. Never open the furnace door with the fan on. If the boiler reaches a temperature of 35°C, the pump (or both pumps
depending on the operating mode) will start.
