REGULATION
Before performing any regulation, disconnect
the electricity supply to the appliance.
After carrying out any regulation or pre-
regulation operations, any seals must be
replaced by the technician.
The regulation of primary air to our burners is
not necessary.
9) VALVES
Regulation of the “Minimum”:
-
Remove knob “M” (fig. 12 and 12/A) of the tap,
wh
ich is simply pressed on to its rod. The by-
p
ass for minimal rate regulation can be: beside
th
e tap (fig. 12) or inside the shaft. In any case,
to
access to regulation, it can be done trought
th
e insertion of a small screwdriver
‘’D’’
beside
th
e tap (fig. 12) or in the hole
‘’C’’
inside the shaft
of
the tap (fig 12/A).
Turn
the throttle screw to the
r
ight or left until the burner flame has been
adequately regulated to the “Reduced rate”
pos
ition.
Th
e flame should not be too low: the lowest small
fl
ame should be continuous and steady. Re-
assemble the several components.
It is understood that the aforementioned
regulation must only be carried out with
burners which use G20, while for burners
which use G30 the screw must be blocked
completely.
Th
e operations described above can be carried
out
easily, whatever the position of the hob or
how
ever it is fastened to the unit.
THE BURNERS DO NOT REQUIRE ANY
REGULATION OF THE PRIMARY AIR.
10) REPLACING NOZZLES
Th
e burners can be adapted to suited different
typ
es of gas by fitting the nozzles that correspond
to
the gas used. To do this, it is necessary to
r
emove the burner heads and use a straight key
“B”,
to unscrew the nozzle “A” (see fig. 13) and
r
eplace it with a nozzle corresponding to the gas
us
ed.
W
e advise you to block the nozzle tightly.
After making these replacements, the
technician must regulate the burners as
described in paragraph 9, seal any regulation
or pre-regulation organs and apply the label
corresponding to the new gas regulation
carried out on the appliance in place of that
previously applied. This label is contained in
the spare nozzle bag.
For
the ease of the fitter, we have prepared a table
indicating the flow capacities, the heat capacities
of
the burners, the diameter of the nozzles and the
work
ing pressure for the various types of gas.
W
ARNING:
To adjust the minimum “DUAL” burner first
remove the bushing “E” (fig. 12).
In the case of a “DUAL” burner, the
regulation screw situated inside the post of
the valve regulates the central flame, while
the screw next to the valve regulates the
outer flame.
