5.11.5 Pilot - Gas Train Connection; 5.11.6 Ignition Pilot Burner - Riello RS 1300/EV BLU Installation, Use And Maintenance Instructions

Example RS 1300/EV BLU FS1 with natural gas G20:
Operation at maximum modulating output
Gas pressure at test point 1)(Fig. 23)
Pressure in combustion chamber
102 - 10
A pressure of 92 mbar, column 1, corresponds in Tab. J to an out-
put of 12200 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. 23),
set the maximum modulating output required from the burner op-
eration:
– find the nearest output value in Tab. J for the burner in ques-
tion.
– Read, on the right (column 1), the pressure at the test point
1) (Fig. 23).
– Add this value to the estimated pressure in combustion
chamber.
Example RS 1300/EV BLU FS1 with natural gas G20:
Operation at maximum modulating output
Gas pressure at an output of 12200 kW
Pressure in combustion chamber
92 + 10
pressure required at test point 1)(Fig. 23).

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. 24) as follows:
Model
RS 1300/EV BLU FS1
RS 1600/EV BLU FS1
RS 2000/EV BLU FS1
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.
The data of thermal output and combustion
head gas pressure are related to full open (90°)
gas butterfly valve.
