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. Extract the knobs.
4. Adjust the by-pass pin indicated in Fig. 8.
• When converting from natural gas to LPG, screw
down the by-pass pin clockwise.
• When converting from LPG to natural gas, unscrew
the by-pass pin 1/4 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.
The above adjustment operations can be easily performed,
whatever the positioning or fixing of the cooktop to the
cabinet.
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. 7) the nozzles, replacing them with those required
for the type of gas used (refer to the table on this page).
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,
must be installed on the inlet piping.
The use of pressure regulators for liquified gases (LPG)
is allowed provided they comply with Standard.
