Start-up, calibration and operation of the burner
5.5.3 Minimum gas pressure switch
Adjust the minimum gas pressure switch (Fig. 35) 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 2 mbar and repeat the burn-
er start-up to ensure it is regular.
If the burner locks out again, turn the knob anticlockwise again by
1 mbar.
5.5.4 PVP pressure switch kit
Adjust the pressure switch for the valve leak detection control de-
vice (PVP Kit)(Fig. 36), if present, according to the instructions
supplied with the Kit itself.
