OPERATIONS TO BE PERFORMED WHEN SUBSTITUTING THE INJECTORS
If the injectors are not supplied they can be obtained from the "Service Centre".
Remove the gratings and the burner covers;
Using a wrench, substitute the nozzle injectors;
"J" (left Fig. 13) with those most suitable for the kind of gas for which it is to be used (see
Injector table).
The burners are conceived in such a way so as not to require the regulation of the primary air.
REGULATING THE BURNER MINIMUM SETTING
When switching from one type of gas to another, the minimum flow rate must also be correct
the flame should not go out even when passing suddenly from maximum to minimum flame. To
regulate the flame follow the instructions below:
1.Light the burner
2.Set the cock valve to minimum
On gas valves provided with adjustment screw in the centre of the shaft (fig.14)
Using a screwdriver with max. diameter 3 mm, turn the screw
inside the tap until the correct setting is obtained.
On gas valves provided with adjustment screw on the valve body (fig.15):
Turn the screw "A" to the correct setting with a screwdriver.Normally for G30 gas, fully tighten
the adjustment screw.
LUBRICATION OF THE GAS TAPS

spread a bit of special grease resistant to high temperatures on it.
The operations must be executed by a qualified technician.
