The Safari Chef 2 uses needle valve gas technology where the male spindle sits into a female receptacle. When you open the valve (turning the gas control knob anti clockwise) the male spindle retracts from the female receptacle and gas then flows to the burner. Upon ignition the gas is drawn through at the required rate.
In all cases the “bitemark” is very close to the start of the anti-clockwise knob turn, please see above; the flame on the left is full on and on the right, it is clearly on low yet the control knob is less than 1cm difference in turn position. We accept that the gas control knob will then turn out circa two full revolutions with no change in gas flow.
This is the nature of needle valves and we advise you to remember or mark where the gas is full on and where it is low. The gas from a cartridge is under very high “direct” pressure (i.e. not controlled using a regulator) the high pressure jet and burner work in unison to control the gas release and quality of the flame whilst minimising gas consumption, thereby maximising burn time with each gas cartridge.
The gas control may need some attention to become familiar with the “bite marks”. Realistically the maximum turn required is less than 90 degrees or ¼ turn.
We advise ¼ turn to light and then turn it clockwise if you require reducing the flame size.
