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.
The adjustment is performed with the burner lit, as follows:
–Turn the knob to the minimum position.
Remove the tap knob.
–With a screwdriver turn the screw “A
to
the correct setting.
For LP/PROPANE gas, tighten the adjustment screw completely.
After regulation repeat the operations indicated in paragraph “2. Pressure regulator” at
page 12.
If the cooktop has been disconnected and then connected again to the gas supply line
repeat the operations indicated in paragraph “5. Leak Testing” at page 16.
