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.
