FIG. 10
10) REPLACING NOZZLES
The burners can be adapted to suit different types
of gas by fitting the nozzles that correspond to the
gas used. To do this, it is necessary to remove the
burner heads and use a tubular spanner “B”, to
unscrew the nozzle “A” (see fig. 10) and replace it
with a nozzle corresponding to the gas used.
We advise you to block the nozzle tightly.
After making these replacements, the
technician must regulate the burners as
described in paragraph 7 - 8 - 9, seal any
regulation or pre-regulation organs and apply
the label corresponding to the new gas
regulation carried out on the appliance in place
of that previously applied. This label is
contained in the spare nozzle bag.
For the ease of the fitter, we have prepared a table
indicating the flow capacities, the heat capacities of
the burners, the diameter of the nozzles and the
working pressure for the various types of gas.
