5.12.7 Burner calibration
Note
It is advisable to first set the burner for operating on oil and then
for gas.
FIRING
Set switch 1)(Fig. 25) to "MAN".
During the first firing, during the passage from the 1
st
to the 2
nd
stage, there is a momentary lowering of the fuel pressure caused
by the filling of the 2
nd
stage nozzle tubing. This lowering of the
fuel pressure can cause the burner to lock-out and can some-
times give rise to pulsations.
Once the following adjustments have been made, the firing of the
burner must generate a noise similar to the noise generated dur-
ing operation.
OPERATION
The optimum calibration of the burner requires an analysis of the
flue gases at the boiler outlet and interventions on the following
points:
•
Nozzles
See the information listed on page 19.
•
Combustion head
The adjustment of the combustion head already carried out
(page 20) need not be altered unless the 2nd stage delivery
of the burner is changed.
•
Pump
pressure
:
In order to adjust pump pressure, use the relevant screw
5)(Fig. 23). See the information listed on page 19.
WARNING
Execute the fuel exchange when the burner is
off.
