INJECTORS REPLACEMENT
• Remove the pan supports.
• Remove the burner's caps and crowns.
• With a socket spanner 7 unscrew and remove the
injectors (Fig. 6), and replace them with the ones
required for the type of gas in use (see table 2).
• Reassemble the parts, following the same procedu-
re 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. 7). If changing from natural gas "E" to
natural gas "LL", undo the by-pass screw until a
small regular flame is obtained. If changing from
natural gas "E" to LPG, completely tighten clockwise
the screw, until a small regular flame is obtained.
• 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.
