ADAPTING TO DIFFERENT TYPES OF GAS
If the cooker is not already preset to operate with the
type of gas available, it must be converted. Proceed
as follows:
- Replace the injectors (see table on page 23);
- 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 INJECTORS (Fig. 4)
- Remove the grid, the burner caps (A), and the burners
(B);
- Unscrew and remove the injector in the bottom of each
injector holder (C);
- replace the injector in accordance with the table in
page 23, using a 7 mm socket wrench, tighten and
screw right down;
- check that the system is gas-tight;
- replace the burners, the burner caps and the grid.
IMPORTANT:
- Never over-tighten the injectors;
- after replacing, check that all the injectors are airtight.
REPLACING THE OVEN BURNER INJECTOR (Fig.
5a)
- Loose the screw securing the oven bottom;
- remove the oven bottom (push back and raise);
- remove the oven burner, after taking out its fixing
screw;
- replace the injector, using a 7 mm socket wrench.
REPLACING THE GRILL BURNER INJECTOR (Fig.
5b)
- 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.
SETTING HOB BURNER MINIMUM LEVELS
If the cooker is to work on bottled gas (butane/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 inserting a small screwdriver
into the rod) or type B taps, with by-pass on the outside
on the right (accessed directly). See figure 6.
If the cooker is to work on natural gas, proceed as fol-
lows 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 even in quite strong draughts.

SETTING OVEN BURNER MINIMUM LEVELS
If the cooker is to work on bottled gas (butane/propane),
the thermostat by-pass must be screwed right down.
If the cooker is to work on natural gas, proceed as
follows:
- Remove the oven bottom (push towards the back and
raise);
- ignite the oven burner, turning the knob pointer to the
maximum setting;
- shut the oven door;
- access the thermostat or tap by-pass (see fig. 7);
- back off the thermostat by-pass by about 3 turns;
- after 5 or 6 minutes, turn the knob pointer to the mini-
mum setting;
- slowly retighten the by-pass, watching the flame de-
crease in size through the window in the closed oven
door until the tongue of the flame is about 4 mm long.
Never keep the flame too low. It must be stable even
when the oven door is opened or closed quickly;
- turn off the burner and replace the oven bottom.
REGULATING THE BURNER AIR
Refer to the table below for regulation of the gap H in
mm:
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 insuf-
ficient, the flame has a yellow tip and soot may form.
CONNECTING TO THE ELECTRICAL MAINS
Before making the connection, check that:
- the mains voltage is as indicated on the nameplate;
- the earth connection is in good working order.
If the appliance power lead is not fitted with a plug, use
an approved standard type, remembering that:
- the green-yellow wire must be used for the earth connection;
- the blue wire is the neutral;
- the brown wire is live;
- the lead must never touch hot surfaces over about 75
degrees C;
- replacement leads must be of type H05RR-F or
H05V2V2-F of suitable size (see diagrams in fig. 2).
- if the appliance is supplied without lead, using type
H05RR-F or H05V2V2-F cable of suitable size (see
diagrams in fig. 2).
