Minimum gas pressure switch

Adjust the minimum gas pressure switch (Fig. 36) after having
performed all other burner adjustments with the pressure switch
set to the start of the scale.
With the burner operating at maximum output, increase adjust-
ment pressure by slowly turning the relative knob clockwise until
the burner locks out.
Then turn the knob anticlockwise by 0,2 kPa (2 mbar) and repeat
the burner start-up to ensure it is regular.
If the burner locks out again, turn the knob anticlockwise again by
0,1 kPa (1 mbar).
