On gas valves provided with adjust-
ment screw in the centre of the shaft
(fig. 5.5):
– Using a screwdriver with max. diame-
ter 3 mm, turn the screw inside the tap
until the correct setting is obtained.

ment screw on the valve body (fig. 5.6):
– Turn the screw “A” to the correct set-
ting with a screwdriver.
For G 30/G 31 gas, tighten the adjust-
ment screw completely.
