Adjusting the minimum flame position
First of all, make sure that the appliance is unplugged from the mains electrical
supply and that the gas feed is open.
The minimum flame position is adjusted with a flat screw located on the valve. As
shown in the figures below; for valves with a flame failure safety device, the screw is
located on the side of the valve spindle and for valves without a flame failure safety
device, the screw is located inside the valve spindle. To make adjusting the flame
position easier, we recommend that you remove the control panel (and the micro
switch if your model has one) during the alteration. The bypass screw must be
loosened for conversion from LPG to natural gas. For conversion from natural gas to
LPG, the bypass screw must be tightened.
Determining the minimum flame position
To determine the minimum position, ignite the burners and leave them on in the
minimum position. Remove the knobs to gain access to the screws. With the help
of a small screwdriver, fasten or loosen the bypass screw by around 90 degrees.
When the flame has a length of at least 4mm, the gas is well distributed. Make sure
that the flame does not die out when passing from the maximum position to the
minimum position. Create an artificial wind with your hand towards the flame to see
if the flames are stable.
