The photocell does not detect the flame during the burning process:
If the photocell does not see any flame during the 30 seconds, ventilator stays running for the
next 30 seconds before the burner provides the normal burning out process according to the
value set on the P4. When the burning out phase is finished and the heat from the boiler
thermostat is still needed, the normal starting phase takes the place again. If the burner is not
ignited in this attempt, ALARM is signalized by a constant lightning of green control light LD3.
If it is needed to change the burner factory settings, please read the chapter: Control electronic
settings and Burner settings.

The burner was set in the factory, however it is needed to synchronize it once again with the
actual operational conditions.
Intervals of pellet feeding can be changed on the control panel to synchronize them with the
pellet diameter, required output and the grade of feeding appliance (max. 45°)
Factory settings of intervals are described in the tabel in chapter: "Control electronic settings" as
well as on internal side of the burner cover. If you are changing these intervals, write the
changes into the tabel and keep it for further use.

Changing the intervals, veltilator flap
When providing any changes, it is necessary to provide the new meassurements after the
installer has set the burner with the kit for flue gas to assure the correct combustion and low
pellet consumption.
Ventilator flap is opened for 30 mm from the factory.
The flue gas temperature can change by increasing or decreasing the interval of feeding the
pellets and corresponding ventilator flap settings (bigger opening in higher inlet and smaller
opening in lower inlet). Necessary flue gas temperature depends on the type of the chimney,
where the boiler is attached. Brick chimneys require higher temperature, because here the
temperature usually decreases of 15-20 °C per meter and in chimney from steel it decreases of 5-
10 °C per meter. The temperature in 1 m below the chimney top should not be lower than 60 °C.
This disables the condensate creation and thus damaging the chimney, caused by freeze.

photocell has lost the flame for 30 seconds
