setting.
Pressure-regulator setting
The adjustment screw can be rotated
through a range of 60 turns for the
purpose of adjusting the outlet
pressure. Three clockwise turns
increase pressure by 1 mbar, while
three anticlockwise turns decrease it by
the same amount.
During startup:
· At least 10 clockwise turns (+)
· Carry out subsequent fine-adjustment
(higher or lower pressure)
· Check gas pressure either at
multiblock pBr (M4) or at gas
pressure nipple 119.1.
Ignition throughput setting
· Unscrew plastic cap B.
· Turn over and use as tool for turning
Sealed
the adjustment screw (three turns
screw
between minimum and maximum
settings).
· Reduce initial throughput by turning
clockwise, or by turning anticlockwise
to increase.
Adjustment of throughput stage 2
· Loosen locking screw.
IMPORTANT: The counter-locked
sealed screw MUST NOT be
loosened.
· Reduce gas throughout by
anticlockwise rotation of adjustment
knob C located on upper section of
magnet coil. Turn clockwise to
increase throughput.
Note:
The adjustment setting of the gas
throughput for stage 2 can affect stage
1. If this occurs, stage 1 must be
readjusted.
Retighten the locking screw once the
adjustment operation is complete.

Gas-pressure switch adjustment
· Remove transparent cover.
Adjustment is carried out by turning
the adjustment screw with circular
scale and index x .
· Adjust provisionally to minimum
setting.
Adjustment of throughput stage 1
by hand (without use of tool).
· Reduce gas throughout by clockwise
rotation of ring D located on bottom
section of the magnet coil. Turn
anticlockwise to increase gas
throughput (three turns between
minimum and maximum settings).
