Pilot - Gas Train Connection; Ignition Pilot Burner - Riello RLS 1000/M C13 Installation, Use And Maintenance Instructions

Example RLS 1000/M C13 with natural gas G20:
Operation at maximum modulating output
Gas pressure at test point 1)(Fig. 26)
Pressure in combustion chamber
A pressure of 39.2 mbar, column 1, corresponds in Tab. I to an
output of 8000 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. 26),
set the maximum modulating output required from the burner op-
eration:
– find the nearest output value in the table Tab. I for the burner
in question.
– read, on the right (column 1), the pressure at the test point 1)
(Fig. 26).
– Add this value to the estimated pressure in the combustion
chamber.

Pressure in combustion chamber
39.2 + 5
pressure required at test point 1)(Fig. 26).

5.13.5 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).
Oil burners (with LPG pilot) can be directly connected to the LPG
cylinder.
Supply pressure 68 - 500 mbar
WARNING

5.13.6 Ignition pilot burner

For proper operation, adjust gas pressure (measured at pressure
test point 1)(Fig. 27) as follows:
Model Gas
RLS 1000/M C13 G20
G31
RLS 1200/M C13 G20
G31
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.
