REGULATION AND TRANSFORMATION OPERATIONS
10) REPLACING NOZZLES
The burners can be adapted to suited 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 straight key
“B”, to unscrew the nozzle “A” (see fig. 13) 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 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.
