5.5.3 Minimum output
Minimum output must be selected within the firing rate range
shown on page 9.
Press switch 2)(Fig. 25) “output reduction” until the servomotor has
closed the air damper and the gas butterfly valve to 15° (factory set
adjustment).
Adjusting gas delivery
Measure the delivery of gas from the gas meter.
–
If this value is to be reduced, decrease the angle of orange cam
(Fig. 24) slightly by proceeding a little at a time until the angle
is changed from 15° to 13° or 11°....
– If it has to be increased press the switch “output
increase” 2)(Fig. 25) (i.e. open the gas butterfly valve by 10-
15°), increase the orange cam angle (Fig. 24) with small suc-
cessive movements, i.e. take it from angle 15° to 17° - 19°....
Then press the switch “output decrease” until the servomotor is
taken to the minimum opening position and measure the gas
delivery.
NOTE:
The servomotor follows the adjustment of cam only when the
cam angle is reduced. If it is necessary to increase the cam an-
gle, first increase the servomotor angle with the switch “out-
put increase”, then increase the orange cam angle, and at the
end bring the servomotor back to the MIN output position with
the switch ”output decrease”.
Adjustment of air delivery
Progressively adjust the starting profile of cam 4)(Fig. 26) by turn-
ing the screws working through the access hole 6)(Fig. 26).
5.5.4 Intermediate outputs
Adjustment of gas delivery
No adjustment of gas delivery is required.
Adjustment of air delivery
With the switch 1)(Fig. 25) move in intermediate outputs and set
the variable profile cam 4) by turning the screws 5).
–
If the burner operation is low-high it is sufficient to set only min-
imum and maximum firing rates
– If the burner operation is modulating, all the points of modula-
tion should be adjusted.
When the adjustment is complete, release the servomotor and
manually check there is no binding of the cam.
