and ash, if available these residues should be cleared away
;
In case that the power supply has been interrupted, at its renewal the
burner will continue its operation automatically;

Operating control parameters of the burner of series “GP”
The control board of the burner has factory preset operating parameters
values, which in common case are satisfying the requirements of a system and
does not require any intervention and variation. The optimal operating
conditions, however are achieved by adjustment of the thermal capacity (by
adjustment of the thermal capacity potentiometer) and adjustment of the air flow
rate control flap, its position should correspond to the position of the thermal
capacity potentiometer position, determined according to its own color scale.
The control board is equipped with various LEDs (with different colors),
which indicate the operating mode of the unit and its adjustment indexes values.
The adjustment of the operating parameters of the burner should be performed
by a trained authorized technician;
ATTENTION :
any adjustment actions, which require detachment of the
burner’s cover and any possibility of contact with high voltage elements, should
be performed by authorized technician only;
●
Description of LED indication (positioned on the control board of the
unit):
Green
and
yellow
LEDs are blinking in series mode – they are indicating
operating information
for the status of the burner. This information could
be utilized in order to analyze the operating mode of the unit. For example
the number of blinking signals of the
green
LED, indicates the index of
the potentiometer number (P1 … P5), which are positioned on the control
board. The number of the following
yellow
LED blinking signals
indicates the value of the position of the appropriate potentiometer. The
correspondence between the number
yellow
LED blinking and
parameter’s value are given in Table 5.1 and Table 5.2. The
red
LED is
active when the photosensor senses presence of the combustion process.
EXPLANATION :
the emitted visible light from the above mentioned LEDs
could be monitored through the transparent window, positioned above the
control board of the burner, installed on its top cover.
