REGULATING THE BURNER MINIMUM
SETTING
When changing from one type of gas to
another, the minimum tap output must
also be correct, considering that in this
position the flame must be about 4 mm
long and must remain lit even when the
knob is turned sharply from the maximum
to the minimum position.
The adjustment is performed with the
burner lit, as follows:
– Turn the knob to the minimum position.
– Remove the tap knob.
On gas valves provided with adjust-
ment screw in the centre of the shaft
(fig. 5.4):
✓
Using a screwdriver with max. diame-
ter 3 mm, turn the screw inside the tap
until the correct setting is obtained.
On gas valves provided with adjust-
ment screw on the valve body (fig.
5.5):
✓
Turn the screw “A” to the correct set-
ting with a screwdriver.
✓
In models with a gas-lighter incorporat-
ed into the knob, turn screw “A” via the
hole in the microswitch.
For G 30/G 31 gas, tighten the adjust-
ment screw completely.
LUBRICATING THE GAS TAPS
If one of the gas taps becomes hard to
turn, dismantle it, thoroughly clean with
petrol and apply special high-tempera-
ture grease.
Warning!
These operations must be performed by
a specialised engineer.
