CONVERSIONS

12) 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. 14) 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 11, 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 nozzlebag.

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.
