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,
which is simply pressed on to its rod. The by-
pass for minimal rate regulation can be: beside
the tap (fig. 12) or inside the shaft. In any case,
to access to regulation, it can be done trought
the insertion of a small screwdriver ‘’D’’ beside
the tap (fig. 12) or in the hole ‘’C’’ inside the shaft
of the tap (fig 12/A). Turn the throttle screw to the
right or left until the burner flame has been
adequately regulated to the “Reduced rate”
position.
The flame should not be too low: the lowest small
flame 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.
The operations described above can be carried
out easily, whatever the position of the hob or
however it is fastened to the unit.
THE BURNERS DO NOT REQUIRE ANY
REGULATION OF THE PRIMARY AIR.
10) REPLACING NOZZLES
The burners can be adapted to suited different
types of gas by fitting the nozzles that correspond
to the gas used. To do this, it is necessary to
remove the burner heads and use a appropriate
key “B”, to unscrew the nozzle “A” (see fig. 13-
13/A-13/B) and replace it with a nozzle
corresponding to the gas used.
To access the injector, in ultra-fast burners with
DCC AFB, remove the injector cover "A"(fig.13/B).
We 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
working pressure for the various types of gas.
