Adaptation to different types of gas
! ! ! ! !
A. Injectors replacement
•
Remove the pan supports.
•
Remove the burner's caps and crowns.
•
With a socket spanner 7 unscrew and
remove the injectors (Fig. 5), and replace
them with the ones required for the type of
gas in use (see table 2:Injectors).
•
Reassemble the parts, following the same
procedure backwards.
•
Replace the rating label (placed near the
gas supply pipe) with the relevant one for
the new type of gas supply. You can find
this label in the package of the injectors
supplied with the appliance.
Should the feeding gas pressure be
different or variable compared with the required
pressure, an appropriate pressure adjuster
must be fitted on the gas supply pipe, in
compliance with the rules in force.

B. Adjustment of minimum level
To adjust the minimum level of the burners,
proceed as follows:
•
Light the burner.
•
Turn the knob on the minimum position.
•
Remove the knob.
•
With a thin screwdriver, adjust the by-pass
screw positioned in the centre of the gas tap
control shaft (see Fig. 6). If changing from
natural gas 20 mbar to liquid gas,
completely tighten the adjustment screw in.
If changing from liquid gas to natural gas 20
mbar, undo the by-pass screw about 1/4 of
a turn. If changing from natural gas 20 mbar
to natural gas 13 mbar undo the by-pass
screw about 1/4 of a turn. If changing from
liquid gas to natural gas 13 mbar, undo the
by-pass screw about 3/4 of a turn.
•
Finally check the flame does not go out
when quickly turning the knob from the
maximum position to the minimum position.
This procedure can easily be carried out,
anyhow the hob has been positioned or built in
the working top.
