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 proce-
dure 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.
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.
