Fan adjustment
Modulation is based on variable-speed technology.
Modulation is based on variable-speed technology.
The combustion air flow rate can be regulated by varying the mo-
tor speed (rpm).
The proportioning gas train delivers the right amount of fuel, de-
pending on the pressure detected in the purging circuit. So the
flow rate supplied is regulated by changing the rotation speed of
the motor.
The motor speed can be regulated through an adjustment of the
control box.
The adjustments take place on the AZL display on the burner and
are carried out using the following parameters:
NOTE:
The adjustment of the fan (to establish the maximum, mini-
mum and ignition outputs) can occur independently both of
the AZL display and the keys and display on board the ma-
chine. Below is a description of the procedure to carry out
using keys and display on the control box.

Burner adjustment
The optimum adjustment of the burner requires an analysis of
flue gases at the generator outlet.
The burner application at the generator, the adjustment and the
testing must be carried out in compliance with the instruction
manual of the generator itself, including the control of the concen-
tration of CO and CO
2
in the flue gases and of their temperature.
Check in sequence:
–
max output
–
min output
–
output upon ignition
The
MAX output
should be equal to the value requested by the
boiler used. To increase or decrease its value use the external
modulation control.
Measure the gas delivery on the counter to precisely establish the
burnt output.
Using a smoke analyser, measure the value of the CO
2
or the O
2
in order to optimise the burner calibration.
The correct values are shown in “Combustion head” on page 29.
To correct these values act on the gas valve in the following way:
to increase the gas delivery and the CO
2
: turn the screw V1
anticlockwise (unscrew)(Fig. 13 on page 21);
to reduce the gas delivery and the CO
2
: turn the screw V1
clockwise (tighten) (Fig. 13 on page 21).
The
MIN output
should be equal to the value requested by the
boiler used. To increase or decrease its value use the external
modulation control.
Measure the gas delivery on the counter to precisely establish the
burnt output (to be corrected in relation to the pressure of the
gas).
Using a smoke analyser, measure the value of the CO
2
or the O
2
in order to optimise the burner calibration.
The correct values are shown in 6.8.
To correct these values act on the gas valve in the following way:
to increase the gas delivery and the CO
2
: turn the screw V2
clockwise (tighten)(Fig. 13 on page 21);
to reduce the gas delivery and the CO
2
: turn the screw V2
anticlockwise (unscrew) (Fig. 13 on page 21).
The
IGNITION output
should be between the minimum output
and the maximum output. To raise or lower its value, adjust the
parameter P0) using the control panel of the control box (Fig. 6
on page 12).
