Replacing the injectors
Our burners can be adapted to different
types of gas by simply installing the injectors
suitable for the gas you want to use.
To change the injectors on the hob, remove
the burner cup and head and with a 7 mm Ø
socket spanner replace them (fig. 11).
To help the installer, the table on in the
"Technical information" section. gives the
burner nominal heat input, injector diameter
and operating pressure of the different gas
types.
After having replaced the injectors, it
will be necessary to proceed with burner
adjustment as explained in the previous
paragraphs. The technician must replace
any seals after the adjustments have
been made.
