;
8.
The burner is not
running or it stops
No power supply
Check the operation of the control module’s
display, positioned on the interface panel of the
burner.
Check
the
connection
and
electricity
parameters of the burner’s main unit and the
heat consumer power supply – the parameters
should be as follows 220 V, 50 Hz –
it should
be performed by authorized technician only;
Check the correctness of the power supply
connection, according to the applied electrical
scheme –
it should be performed by authorized
technician only;
Check for tightness of electrical joints of the
control board –
it should be performed by
authorized technician only;
Absence of operating signal to
the burner’s main unit
Check the availability of start signal of the
burner. Check the wiring and connection of the
burner’s main unit and the power supply box of
the heat consumer’s power supply - –
it should
be performed by authorized technician only;
Check for tightness of electrical joints of the
control board –
it should be performed by
authorized technician only;
Check the operation and functioning of the
control module, which gives operating signal to
the burner – check the parameters of the power
supply – it should be as follows : 220 V, 50 Hz
–
it should be performed by authorized
technician only;
The burner does not run and
start signal is present
Check if the control board is in alarm mode –
see following table with operating and alarm
indication
Safety fuses are broken due to
emergency short circuit
This check-up operation should be performed
by authorized technician only : check each fuse
status and replace if necessary with
appropriate one (

: safety fuses F1,
F2, F3 and F4 are fast reacting);
9.
The
flame
looks
“opaque” and smoke is
observed at the exit of
the chimney
Low quality fuel
Fuel replacement is recommended, most
probably the moisture content is higher than
required for nominal operation of the burner –
see the requirements in the fuel properties
table;
Inappropriate
operating
parameters adjustment
It is necessary to perform operating parameters
adjustment and achieve efficient combustion
process –
this operation should be performed
by trained authorized personal only
;
10.
The ignition process of
the fuel is successful,
but the unit could not
reach stable operating
mode
Incorrect photosensor
positioning
Change (i.e. slightly rotate or even axially
move) the position of the photosensor
The external surface of the
photosensor is dirty
Clean the transparent section of the photosensor
by careful cleaning – do not use solvents
The photosensor is gone – its
working surface is damaged
and overheating zones are
observed
It is necessary to replace the photosensor –
it
should be performed by authorized technician
only
11.
The operation of the
burner is not stable
Photosensor malfunctioning
Check the condition and functionality of the
photosensor
The operating parameters of
the control board have been
changed
Check the position of the heat capacity
potentiometer
