The above adjustment operations can be easily performed,
whatever the positioning or fixing of the cooktop on the
kitchen cabinet.
Minimum flame adjustment
To adjust the minimum flame, proceed as follows.
1. Light the burner as previously described.
2. Turn the cock to the min. flame position.
3. Remove the knobs.
4. Adjust the by-pass pin indicated in fig. 18.
•
When converting from natural gas to LPG, screw down
the by-pass pin clockwise. When converting from natural
gas to town gas, unscrew it 3/4 turn (approx.).
•
In any case, the result must be a small and even flame
on all the burner crown.
5. Lastly, check that the burner does not go off when
quickly turning the cock from max. to min.
Replacing nozzles
1. Remove the grates.
2. Remove the burner caps and flame spreaders.
3. Using a 7 mm socket wrench, unscrew and remove
(Fig. 16) the nozzles, replacing them with those
required for the type of gas used (refer to table 1 on the
previous page).
To adapt the nozzles for operation on Town gas, after
fitting the special types (fig. 17,
B
) screw the special
cages on to them: for the semirapid and auxiliary
burners use the cage indicated by letter
A
(with Ø 10
hole), and the cage indicated by letter
C
(with Ø16
hole) for the rapid burner and fish kettle burner.
4. Refit the parts by carrying out the above operations in
reverse order.
5. Then replace the rating plate (located near the gas
connection) with that corresponding to the new type of
gas. The latter is included in the bag of injectors
supplied.
If the pressure of the gas used is different (or variable)
from that provided for, a suitable pressure regulator for
the piped gas (
NOT LPG
) complying with Standard UNI-
CIG 7430 must be installed on the inlet piping.
The use of pressure regulators for liquified gases (LPG)
is allowed provided they comply with Standard UNI-CIG
7432.
