It is necessary to perform
adjustment of the operating

it
should be performed by trained
authorized technician
;
The fuels’ ash
content is higher
than recommended
It is necessary to replace the fuel
with appropriate one – see the table
with properties of the recommended

malfunctioning and
the gives improper
signal to the

Check the quantity of the fuel at
nominal mode, delivered on the
burner’s grate:
In case that this quantity is less
than required, than increase the
thermal capacity of the burner or
decrease the air flow rate by
repositioning the control flap of
the air fan;
In case that this quantity is
higher than required, than
decrease the thermal capacity of
the unit or increase the air flow
rate by repositioning the control
flap of the air fan;
