7.1.2 Nozzle pressure method
After a short time, the display will show the stored
operating mode (0. = normal operating mode).
In particular, after switching to another type of gas, the gas
flow must be checked or adjusted for the minimum power
and the maximum maximum heating power.
Gas adjustment, depending on its type
The rated thermal input can be adjusted using the nozzle
pressure method or the volumetric method. A U-tube
manometer is required for both methods.

The nozzle pressure method is faster and is therefore
preferable.
