Properly adjust the composition of the fuel / air mixture.
Remove the burner’s black cover.
a) Make sure that the burner’s heating power setting
corresponds to boiler size. This adjustment is made using
Fig.7 element 1 by turning a screwdriver to the left or right.
b) Initial setting of the air damper is made by turning the
adjustment screw Fig. 9, element 1, for approx. 1 level in line
with Fig. 8, element 2.
c) Using a hexagonal Allen wrench no. 4, turn the knob to
the left to the end as in Fig. 10, element 1, and then turn the
wrench clockwise 1 – 1.5 turn to the right.
Carefully watching the boiler’s chimney outlet (there
should be no black or white smoke), adjust fuel amount to
a satisfying dose (typical setting in the range from extreme
left po 1 turn to the right to 2.5 turns to the right).
Make sure that the burner-boiler assembly does not shake in
the resonance (characteristic loud rumbling noise). In case
fuel pump adjustment range is insufficient, adjust the air
damper Fig. 9, element 1 (typical setting range: 0.5 - 2.0).
This setting and precision adjustment should be conducted
several times until a light flame is achieved in the direct view
window as in Fig. 7, element 2. The target adjustment should
be performed on a heated machine during a third or fourth
boiler heating (normal operation mode), whereas precision
adjustment refers to the machine’s cold start procedure.
NOTE: Since it is not possible to adjust the burner by
performing steps as above, the fuel nozzle must be worn
out. Dismantle the burner and replace the nozzle.
NOTE: Watch for proper installation of fuel supply line
(Fig. 10 element 5) and fuel return line (Fig. 10 element 4)
as per Fig. 10.
Fuel nozzle replacement should be accompanied by proper
setting of ignition electrodes. Distance from nozzle head to
ignition electrodes, and from ignition electrodes to the swirl
vane: as in Figures 11 and 12.
