7.1.5 Preset pressure regulator
Determine setting pressure
Add the combustion chamber pressure in mbar to the setting pressure into the gas
butterfly valve.
Determine setting pressure from the table and note down.
The details given for calorific value H
i
relate to 0 °C and 1013 mbar.
The table values have been calculated under ideal conditions. The values are there-
fore guide values for basic settings.
