Minimum gas pressure switch

Adjust the minimum gas pressure switch after performing all the
other burner adjustments with the pressure switch set to the start
of the scale (Fig. 25).
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 burner start-up to ensure it is operating reg-
ularly. If the burner locks out again, turn the knob again anticlock-
wise by 0.1 kPa (1 mbar).
1 kPa = 10 mbar
