Installation
5.8 Combustion head adjustment
At this point of the installation, the combustion head is fixed to the
boiler as shown in Fig. 16.
It is therefore especially easy to adjust, and this adjustment
depends only on the maximum output of the burner.
In the diagram of (Fig. 14), find the notch at which the combustion
head should be adjusted.
Air adjustment
Rotate screw 1)(Fig. 16) until the notch on the lamina 2)(Fig. 16)
matches the surface of plate 3)(Fig. 16).
Example:
RS 35/M BLU, burner output = 270 kW.
From diagram (Fig. 14) you can see that for this output the air
should be adjusted at notch 3, subtracted from the value of the
pressure in the chamber.
Central air adjustment
In the event that the specific application requires a particular
adjustment, it is possible to change the central air flow rate
moving the ring nut 4)(Fig. 16) until it reaches the notch indicated
by the diagram (Fig. 15).
To carry out this operation, loosen the screws 5)(Fig. 16) and lift
the ring nut 4).
When finished, lock the screws 5) again.
NOTE:
The adjustments indicated can be modified during the initial
start-up.
Once you have finished adjusting the head, reassemble the
burner 4)(Fig. 17) on the slide bars 3)(Fig. 17) at about 100mm
from the pipe coupling 5)(Fig. 17) - burner in the position shown
in 4)(Fig. 11) - 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. 17.
Refit screws 2) on slide bars 3)(Fig. 17).
Fix the burner to the pipe coupling with the screw 1)(Fig. 17).
ATTENTION
To facilitate the adjustment, loosen the screw 5)
(Fig. 16), adjust, then block.
ATTENTION
If the pressure in the chamber is equal to 0 mbar,
the air must be adjusted with reference to the
hatched line on the diagram (Fig. 14).
