Pilot - Gas Train Connection; Ignition Pilot Burner - Riello RS 1000/EV C01 Installation, Use And Maintenance Instructions

Example RS 1000/EV C01 with G20 natural gas:
Maximum modulating output operation
Gas pressure at test point 1) (Fig. 21)
Pressure in combustion chamber
59.2 - 10
A pressure of 49.2 mbar, column 1, corresponds in Tab. K to an
output of 9000 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 1) (Fig. 21),
set the maximum modulating output required from the burner op-
eration:
– find the nearest output value in Tab. K for the burner in ques-
tion.
– read, on the right (column 1), the pressure at the test point 1)
(Fig. 21).
– Add this value to the estimated pressure in the combustion
chamber.
Example RS 1000/EV C01 with G20 natural gas:
Maximum modulating output operation
Gas pressure at an output of 9000 kW
Pressure in combustion chamber
49.2 + 10
Pressure required at test point 1)(Fig. 21).

5.11.5 Pilot - gas train connection

The burner is fitted with a dedicated gas train that is fixed to the
pipe coupling.
➤ It should be connected to the main train downstream the fil-
ter or the pressure adjuster (depending on configuration).
Supply pressure 68 ÷ 500 mbar.
WARNING

5.11.6 Ignition pilot burner

For proper operation, adjust gas pressure (measured at pressure
test point 1)(Fig. 22) as follows:
Model
RS 1000/EV C01
RS 1200/EV C01
Check pilot flame stability before starting up the
main burner.
WARNING
In the case of ignition problems check:
➤ correct positioning of the ignition electrode;
➤ the gas pressure, according to indications.
