Adaptation to different types of gas
WARNING: Servicing shall only be carried out
by authorised personnel.
Substitution of the nozzles
-
Remove the grills;
-
Remove the caps and baffles from the burners;
-
With a tubular spanner no. 7 unscrew and remove
(Fig. 18) the nozzles substituting them with those
corresponding to the type of gas used (see table
on page 14);
-
Remount the parts carrying out the operations
described in reverse. Upon completion remove
existing gas type label and stick the relevant gas
type label near the gas supply pipe.
If the pressure of gas used is different (or variable) from
that foreseen an appropriate pressure regulator should
be installed on the entry tube. In case pressure regulators
for U-LPG are used these should conform to the
regulations in force.
Regulation of the minimum
To regulate the minimum:
-
bring the tap to the minimum flame position.
-
extract the knob.
-
in case of conversion from natural gas to U-LPG,
tightly screw the by-pass screw (Fig. 19);
-
when converting from U-LPG to natural gas
unscrew about ½ turn by-pass screw, until a
regular small flame is reached.
Finally check that by quickly turning the tap from the
maximum position to the minimum position the
burner is not extinguished; remount the parts carrying
out the operations described in reverse.
