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. 12) 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-

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.
