TABLE
*In accordance with Regulation No. 66/2014 EU measures for the implementation of Directive 2009/125/EC,
the performance (EEgas burner) was calculated according to EN 30-2-1 last review with the G20.
**DCC AFB: AIR FROM BOTTOM.
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. Now unscrew injector(see fig. 13 -
13/A - 13/B) and fit a injector corresponding to the
utilized type of gas in its place. To access the
injector, in ultra-fast burners with DCC AFB,
remove the injector cover "A" (Fig. 13/B).
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.
