ADJUSTMENTS
• All seal must be replaced by the technician
following any adjustment or regulation.
• The adjustment of the reduce rate (simmer)
must be undertaken only with
functioning on natural gas while in the case of
burners functioning on L.P.G, the screw must
be locked down fully (in clockwise direction).
• "Primary air adjustment" on hob gas burners
is unnecessary.
TAPS (fig. 21)
All gas taps are male cone type with only one way of
passage. The adjustment screw (V) is on the side of
the stem.
Adjustment of the "Reduced rate" position as follows:
• Turn the burner on and place the knob on the
"Reduced rate" position (small flame).
• Remove the knob of the tap which is attached by
simply applying pressure to the rod.
• Insert a small screwdriver (C) into screw (V ) and
turn to the right or left the throttling cone until the
flame of the burner is conveniently regulated to the
Low position, the adjustment screw (V) is over (fig.
21) or on the side of the stem .
• Check that the flame does not go out when the knob
is sharply switched from the "Full on" to "Reduced
rate" positions.
• ATTENTION!! This operation can be carried out
also with the front panel fitted, but if the technician
finds some difficulties to reach the adjustment
screw, remove the front panel unscrewing the
fixing screws, which are positioned in the inferior
part of the same.
