tions below:
– Light the burner.
– Set the gas tap to minimum.
– Remove the tap knob.
For gas taps provided with adjust-
ment screw in the centre of the shaft
(fig. 6.5):
– Using a screwdriver with max. diame-
ter 3 mm, turn the screw inside the tap
until the correct setting is obtained.
For gas taps provided with adjustment
screw on the body (fig. 6.6):
– Turn the screw "A" to the correct set-
ting with a screwdriver.
For G30/G31 gas, tighten the adjust-
ment screw completely.
