Example RS 1000/M BLU with natural gas G20:
Maximum modulating output operation
Gas pressure at test point 1) (Fig. 22
Pressure in combustion chamber
A pressure of 36.9 mbar, column 1, corresponds in the table Tab. J
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. 22),
set the maximum modulating output required from the burner op-
eration:
20058944
) = 41.9 mbar
= 5 mbar
41.9 - 5 = 36.9 mbar
Installation
– find the nearest output value in the table Tab. J for the burner
in question.
– Read, on the right (column 1), the pressure at the test point 1)
(Fig. 22).
– Add this value to the estimated pressure in the combustion
chamber.

= 36.9 mbar
= 5 mbar
36.9 + 5 = 41.9 mbar
