7.1.5 Preset pressure regulator
Determine setting pressure
An additional pressure regulator is required for connection pressure > 50 mbar.
Set FRS pressure regulator [ch. 7.1.6].
Add the combustion chamber pressure in mbar to the setting pressure.
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.
