10) REPLACING THE INJECTORS
The burners can be adapted to different types of
gas by mounting injectors suited to the type of gas
in question. To do this, first remove the burner
tops using a wrench "B". Now unscrew injector "A"
(see fig. 13) and fit a injector corresponding to the
utilized type of gas in its place.
It is advisable to strongly tighten the injector in
place.
After the injectors have been replaced, the burners
must be regulated as explained in paragraphs 9.
The technician must reset any seals on the
regulating or pre-regulating devices.
The envelope with the injectors and the labels can
be included in the kit, or at disposal to the
authorized customer Service Centre.
For the sake of convenience, the nominal rate table
also lists the heat inputs of the burners, the diameter of
the injectors and the working pressures of the various
types of gas.
