5.1.8 Setting of the minimum power of gas burners
The reduced (minimum) power is factory set. After replacing the nozzle to adjust to
the available gas or particular pressure conditions in the supply network, it may be
necessary to change the minimum power settings.
Adjust settings in the following way:
-
ignite the burner and let it burn for
ca. 10 minutes with maximum power;
-
turn the burner control knob to the
minimum position;
-
pull out the control knob;
-
set the minimum position using a small
screwdriver by turning the bypass screw
clockwise, until obtaining the required flame
power;
Fig. 12
Replace the control knob and quickly turn it from the maximum position to the
minimum position and check the flame. Make sure that it still allows for correct
heating of the thermocouple. If not, correct again the minimum flame setting.
After replacement of nozzles or other adjustments, always make sure that the flame
is blue, stable and soundless, and that it does not separate from the burner, and
there is no back burning while changing from the large flame to small flame.
CAUTION!
The device functions properly only when the pressure in the gas installation is
within the values given in the table labeled
“Gas categories in selected
countries
” on pp. 48, 49.
CAUTION!
Properly reassemble all parts after making alterations or recalibrating the
device to ensure it is prepared for further use.
Inspect gas installation seals using a soap solution, never by using an open
flame.
After adaptation, remove the old sticker with regulation values and replace it
with a new one appropriate for the new gas type.
