MINIMUM FLOW ADJUSTMENT FOR COOKTOP GAS TAPS
IMPORTANT!
All work must be carried out by a registered gas fitter and in
accordance with the current standards.
WARNING!
Always isolate the cooktop from the electricity and gas
supply before changing the injectors and/or adjusting the
minimum flow of the burners.
► Switch the burner on and set the knob at the minimum
position.
► Remove the knob from the tap and place a small bladed
screwdriver in the centre of the tap shaft.
► Unscrew the adjusting screw, in order to increase the
gas flow or tighten the adjusting screw to decrease the
gas flow.
► The correct adjustment is obtained when the flame has
a length of about 3 – 4 mm.
► For ULP gas, the adjusting screw must be tightly
screwed in.
► Refit the control knob.
► Make sure that the flame does not go out by quickly
turning from maximum flow to minimum flow. If it
does then remove the control knob and make further
adjustments to the gas flow, testing it again once the
adjustment has been made.
► Repeat this process for each one of the gas taps.
► When converting from Natural Gas to ULP gas ensure
that the NG regulator is removed and replaced with
the Test Point Assembly. A gas regulator suitable for a
supply pressure of 2.75kPa should be at the inlet to the
appliance. Replace the old data plate with one which is
suitable for the type of gas for which the appliance has
been regulated.
IMPORTANT!
Where this appliance is installed in marine craft or in
caravans, it shall not be used as a space heater.
