COMBUSTION HEAD SETTING

Installation operations are now at the stage
where the blast tube and sleeve are secured to
the boiler as shown in fig. (A). It is therefore par-
ticularly easy to adjust the combustion head.
Air adjustment (A - B)
Rotate the screw 1)(A) until the notch on the
lamina 2)(A) corresponds with the surface of the
plate 3)(A).
Example:
RS 44/1 MZ burner, output = 300kW.
From diagram (B) you can see that, for the MAX
output of 300 kW, the air should be adjusted at
notch 4, subtracted from the value of the pres-
sure in the chamber. In this case, the loss of
pressure in the combustion head is shown in col-
umn 1 on page 6 - 7.
Note
If the pressure in the chamber is equal to 0 mbar,
the air is adjusted with reference to the broken
line of the diagram (B).
Central air adjustment (A - C)
n case the application needs a particular setup,
it is possible to modify the central air delivery
using the ring nut 4)(A) up to the notch indicated
in diagram (C).
In order to carry out this operation, unscrew the
screws 5)(A) and lift up the ring nut 4)(A). At the
end, tighten the screws 5)(A) again.
Once you have finished adjusting the head,
reassemble the burner 4)(D) on the guides 3)(D)
at about 100mm from the pipe coupling 5)(D) -
burner in the position shown in fig. (C)p.8 -
insert the cable of the probe and the cable of the
electrode, then slide the burner as far as the
pipe coupling, burner in the position shown in
fig. (D).
Refit the screws 2) on the guides 3).
Fix the burner to the pipe coupling with the
screw 1).
