Installation instructions
Converting the cooktop to a different gas type
Important!
Only a suitably qualified and registered person may convert the cooktop to a different gas type.
To convert from one gas type to another, you need to replace the injectors, and then
adjust the minimum gas rate setting.
Replacing the injectors
1 Remove the pan supports and burners from the cooktop.
2 Using a spanner, remove the injectors and replace them with ones suitable for the type of gas
you are converting the cooktop to. See the ‘Table for the choice of injectors’.
The burners are designed so that regulation of primary air is not required.
Adjusting a burner’s minimum gas rate setting
Check whether the flame spreads to all burner ports when the burner is lit with the gas valve set
to the minimum position. If some ports do not light, increase the minimum gas rate setting.
Check whether the burner remains lit even when the gas valve is turned quickly from the
maximum to the minimum position. If the burner does not remain lit, increase the minimum gas
rate setting.
To adjust the minimum gas rate setting
1 Make sure the burner is lit.
2 Turn the knob to the minimum position.
3 Remove the knob.
4 Using a screwdriver, turn the adjustment screw
until the flame setting is correct.
For LPG, tighten the adjustment screw completely.
