Start-up, calibration and operation of the burner

Adjustment of air delivery

Progressively adjust the starting profile of cam 4)(Fig. 27) by
turning the screws working through the access hole 6)(Fig. 27). 
It is preferable not to turn the first screw since this is used to set
the air damper to its fully closed position.

6.5.3

Max. output

Max. output of the burner must be set within the firing rate range
shown on Fig. 2 on page 10.
In the above description, we left the burner switched on, working
at MIN output. Now press the button 2)(Fig. 26 on page 24)
“output increase”, and keep it pressed until the servomotor has
opened the air damper and the gas butterfly valve at 90°.

Adjusting gas delivery

Measure the gas delivery at the meter.
As a general rule, it can be seen from the Tab. F on page 20, just
read the gas pressure on the pressure gauge, see Fig. 25, and
follow the indications given on "Gas pressure” on page 20.

If delivery needs to be reduced, diminish outlet gas pressure
and, if it is already very low, slightly close adjustment valve
VR.

If delivery needs to be increased, increase outlet gas
pressure.

Adjustment of air delivery

Progressively adjust the end profile of cam 4)(Fig. 27) by turning
the cam adjustment screws as they appear through the access
opening 6)(Fig. 27).

Turn the screws clockwise to increase air delivery.

Turn the screws anti-clockwise to reduce air delivery.

Adjusting gas delivery

No adjustment of gas delivery is required.

Adjustment of air delivery

Press the key 2)(Fig. 26) “output increase” a little so that a new
screw 5)(Fig. 27) appears in the opening 6)(Fig. 27). 
Adjust it until optimal combustion is obtained. Proceed in the
same way with the other screws.
Take care that the cam profile variation is progressive.
Switch the burner off with the switch 1)(Fig. 26). Release the
variable profile cam by putting the servomotor slot 2)(Fig. 27) in
a vertical position and check more than once, rotating the cam
forward and backward by hand, that the movement is soft and
smooth, without sticking.
As far as is possible, try not to move those screws at the ends of
the cam that were previously adjusted for the opening of the air
damper to MAX and MIN output.

NOTE:
Once you have finished adjusting outputs MAX - MIN -
INTERMEDIATE, check ignition once again: noise emission
at this stage must be identical to the following stage of
operation. If you notice any sign of pulsations, reduce the
ignition stage delivery.
