Properly adjust the composition of the fuel / air mixture. Re-
move the burner’s black cover.
a) Make sure that the burner’s heating power setting corre
-
sponds to boiler size. This adjustment is made using Fig. 4
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. 6, element 1, for approx. 1 level in line
with Fig. 6, element 2.
c) Using a hexagonal Allen wrench no. 4, turn the knob to
the left to the end as in Fig. 7, 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 satis
-
fying 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 damp
-
er Fig. 6, element 1 (typical setting range: 0.5 - 2.0). This set
-
ting and precision adjustment should be conducted several
times until a light flame is achieved in the direct view win
-
dow as in Fig. 4, 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 per-
forming 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. 7 element 5) and fuel return line (Fig. element 4) as
per Fig. 7.
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 8 and 9.
