yes looking at the MI's you have to set max burner pressure to 15.4 mbar using a preset on the pcb and also the ignition pressure to 6mbar. If you don't do the latter you could find the gas valve sticks later in life.
Do you need a copy of the mi's? attach email address if so.
If it's the one I'm thinking of there is a little black tool clipped onto the pcb cover which you stick into two of the three holes in the cover to set your gas rates.
