Installation
Example with natural gas G20:
Operation at maximum modulating output
Gas pressure at test point 1) (Fig. 28)
= 35.2 mbar
Pressure in combustion chamber = 5 mbar
35.2 - 5 = 30.2 mbar
A pressure of 30.2 mbar, column 1, corresponds in the table Tab.
L to an output of 6000 kW.
This value serves as a rough guide; the effective output must be
measured at the gas meter.
To calculate the required gas pressure at test point P1) (Fig. 28),
set the maximum modulating output required from the burner
operation:
–
find the nearest output value in the table Tab. L for the burner
in question.
– Read, on the right (column 1), the pressure at the test point
P1)(Fig. 28).
– Add this value to the estimated pressure in combustion
chamber.
Example with natural gas G20:
Operation at maximum modulating output
Gas pressure at an output of 6000 kW
= 30.2 mbar
Pressure in combustion chamber = 5 mbar
30.2 + 5 = 35.2 mbar
pressure required at test point P1)(Fig. 28).

5.13.5 Pilot - gas train connection
The burner is equipped with a dedicated gas train fixed to the
sleeve.

Connect it to the main gas train, downstream of the filter or
pressure adjuster (according to the configuration).
Oil burners (with LPG pilot) can be directly connected to the LPG
cylinder.
5.13.6 Ignition pilot
For proper operation, adjust gas pressure (measured at pressure
test point 1)(Fig. 29) as follows: 16 mbar (7.3 Nm
3
/h).
In case of ignition problems, check:

the correct positioning of the ignition electrode;

the gas pressure, according to the specifications.

ATTENTION
Supply pressure 68 ÷ 500 mbar.
ATTENTION
Check the stability of the pilot flame before igniting
the main burner.
