ADAPTING TO DIFFERENT TYPES OF
GAS
If the cooker is not already preset to operate
with the type of gas available, it must be con-
verted. Proceed as follows:
- Replace the injectors (see table on page
24);
- regulate the primary air flow;
- regulate the minimum settings.
N.B.: every time you change the type of gas,
indicate the new type of gas on the serial
number label.
REPLACING THE HOB BURNER INJEC-
TORS (fig. 4)
- Remove the lid of the cooker by lifting it off
its supports;
- remove the grids, burner caps and burners,
lifting them off;
- unscrew the 2 screws (above) or nuts
(below) at the back which secure the work
top, and pull it out forward.
- remove the mixer pipes and replace the
injectors using a 7 mm socket wrench.
REPLACING THE OVEN BURNER INJEC-
TOR (Fig. 5)
- Loosen the screw which secures the bottom
of the oven;
- remove the oven bottom (pulling it forward);
- remove the oven burner, after taking out
the screw which secures it;
- replace the injector using a 7 mm socket
wrench.
REPLACING THE GRILL BURNER INJEC-
TOR (Fig. 6)
- Remove the burner after taking out the two
screws which secure it;
- replace the injector using a 7 mm socket
wrench.
IMPORTANT:
- Never over-tighten the injectors;
- after replacing, check that all the injectors
are airtight.
REGULATING THE BURNER AIR
Refer to the table below (indicative values)
for regulation of the gap H in mm (fig. 4 for
the hob, fig. 6 for the grill).
Check operation of the burner:
- Ignite the burner at maximum flame;
- the tongue of the flame must be clear and
with no yellow tip, and must adhere closely
to the burner. If too much air is supplied,
the flame detaches from the burner and
may be dangerous. If the air supply is in-
sufficient, the flame has a yellow tip and
soot may form.
SETTING HOB BURNER MINIMUM LEV-
ELS
If the cooker is to work on bottled gas (bu-
tane/propane), the tap by-pass must be
screwed right down.
The cooker may be equipped with type A
taps, with by-pass inside (accessed by in-
serting a small screwdriver into the rod) or
type B taps, with by-pass on the outside on
the right (accessed directly). See figure 7.
If the cooker is to work on natural gas, pro-
ceed as follows for both types of tap:
- Ignite the burner at maximum flame;
- pull off the knob, without using a lever
against the control panel, which might be
damaged;
- access the by-pass with a small screwdriver
and back off by about 3 turns (turning the
screwdriver anti-clockwise);
- turn the tap rod anti-clockwise again until it
stops: the burner will be at maximum flame;
- screw the by-pass slowly back in, without
pushing the screw-driver, until the flame has
apparently shrunk to 1/4 of the maximum
size, checking that it is sufficiently stable
