in the pilot burner, following the indications given in the following paragraphs. The type of nozzle
to install can be found in table 2, 3, 4, 5 - pag. 23, 24. The nozzles for the main burner, marked with the
relative diameter in hundredths, and the ones for the pilot burner, marked with a number, can be
found in a transparent packet attached to the instruction booklet.
When the conversion is completed, check the tightness of the pipe fittings and also that the ignition
and functioning of both the pilot burner and main burner, at both minimum and maximum, are
correct. It may be necessary to check the output (power).
Substituting the burner nozzle (fig. 10 - pag. 4)
To substitute the burner nozzle, open the compartment door and unscrew the nozzle (1) from the
nozzle holder (2), and open it completely, unscrew the nozzle (3) with a spanner and substitute it
