6. Adapting cook-top to different types of gas
To adapt the hob to a type of gas that differs
from the one tested in the factory (see data plate
or supplementary plate), replace the nozzles of
the five burners Remove the pan carrier grilles
from the hob and withdraw the movable parts of
the burners from their seats:
-
Remove the pot support grids from the
cook-top and remove the mobile parts of
the burners from their position.
-
Unscrew the jets (Fig. 2) using the 7 mm.
Key and replace them with the new ones
(see
table
1).
Check
the
exact
correspondence of the diameter indicated
on the table with that printed on the jets.
After having replaced the jets, set up all the parts
again and stick the new data on the technical
data plate.
Fig. 2
N.B. The burners don’t need any air regulation.
Minimum level adjustment - Burner minimum levels are preset for methane gas (G20) operation.
If operating on liquid gas (G30/G31) proceed as follows: ignite the burner at minimum position,
and, using a screwdriver, fully tighten the by-pass adjustment screw at the side of the shank of
the relevant tap. Check if the flame remains stable and uniform – to help you check, rapidly
turn the tap knob from maximum to minimum position. When you have finished adjusting the
by-pass valve, seal it with red paint. Make sure you fit a plate with the new installation data.
After having set the by-pass screw, seal it with red varnish.
