Lighting
Check before lighting
Before lighting the boiler:
-
make sure to have read and understood the information given in the manual;
-
follow the oral instructions on operation of the unit provided by the installer prior to use.
-
the hopper must be filled with pellets;
-
the combustion chamber must be clean;
-
the brazier must be completely free, cleaned of any combustion residuals and correctly fitted in the brazier holder;
-
check hermetic closing of the ash box and fire door;
-
check the connection of the power cable and switching to ON/1 of the switch located on the back of the boiler.
-
check opening of the delivery and return shutoff valves as well as the water circuit pressure.
Any lighting done after long idle periods requires the removal of any residual pellets that have remained inside
the hopper, in being damp fuel no longer suitable for combustion, and complete cleaning of the combustion
chamber.
Startup stage
To light the boiler, press the button 'P4' for 3 seconds: the message 'START' will appear on the display.
This stage is automatic and managed entirely by the electronic controller without the possibility of changing the parameters.
Alternatively the boiler can be lit by pressing the buttons P4 and P5 together for 3 seconds. The message AWAITING REQUEST
appears on the display. With this mode the boiler switches to standby status and carries out the lighting-start stage only if a request
for heat is recognised, e.g. to heat the water or for DHW (if available).
