If you are not sure, proceed as follows:
- Check whether the worm conveyor is really working by plugging the conveyor connector directly
to a wall socket, if so
-
Turn off and on the main switch of the boiler and watch the lighting and flashing symbols on the
display of the electronic unit. Each start over a particular symbol on the display means that the
element or function is in operation or should be.
Each symbol on the display characterizes one element or function of the burner.
- Indicates operation of the external conveyor
- Indicates connected control thermostat of the boiler
- Indicates connected ignition spiral 1
- Indicates connected ignition spiral 2
- Indicates the fan running at the starting or
operation speed
- Indicates connected reserve output R (bottom *)
- Indicates connected reserve output R2 (top *)
- Indicates that the photocell sees the flame
-
If an error message related to the damage of a particular part on the burner appears immediately,
you should call the customer service to replace the damaged part

If no error message appears, you must watch and compare the function of individual elements in
the burner by checking which symbol on the display is flashing or lighting up. This way you can
easily locate a possible defect within the burner (faulty part).
