10) REPLACING THE INJECTORS
The burners can be adapted to different types of
gas by installing injectors suited to the type of gas
required. To do this, first remove the burner tops
using a wrench “B”. Now unscrew injector “A” (see
fig. 11) and fit a injector corresponding to the type of
gas required.
It is advisable to tighten the injector in place.
After the injectors have been replaced, the
burners must be regulated as explained in
paragraphs 7. The technician must reset any
seals on the regulating or pre-regulating devices
and affix the label corresponding to the new gas
regulation on the appliance instead of the already
existing one. This label is supplied in the packet
containing the spare injectors.
The envelope with the injectors and the labels can
be included in the kit, or at disposal to the
authorised customer Service Centre.
For the sake of convenience, the nominal rate chart
also lists the heat inputs of the burners, the
diameter of the injectors and the working pressures
of the various types of gas.
