Installation
To calculate the required gas pressure at test point 1) (Fig. 28),
set the maximum modulating output required from the burner op-
eration:
-
find the nearest output value in Tab. H for the burner in ques-
tion.
- read, on the right (column 1), the pressure at the test point 1)
(Fig. 28).
- Add this value to the estimated pressure in combustion
chamber.
Example RLS 1600/EV C11 with natural gas G20:
Operation at maximum modulating output
Gas pressure at an output of 12400 kW
= 41 mbar
Pressure in combustion chamber = 5 mbar
41 + 5 = 46 mbar
pressure required at test point 1)(Fig. 28).
5.14.5 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).
5.14.6 Ignition pilot burner
For proper operation, adjust gas pressure (measured at pressure
test point 1)(Fig. 29) as follows:
Tab. I
In the case of ignition problems check:

correct positioning of the ignition electrode;

the gas pressure, according to indications.
