Converting to a different gas type
Important!
Gas conversion may only be carried out by a suitably qualified and registered person.
To convert from one gas type to another, you need to replace the injectors and adjust the minimum burner setting.
To replace the injectors, you will need a 7 mm box spanner (and a 10 mm ring spanner for CG905DWAC models). These are not supplied.
1Disconnect the cooktop from the power supply.
Important!
Disconnect cooktop from the power supply before continuing.
2Make sure each control dial is turned to O (OFF).
3 Remove all the pan supports and burner heads.
4 Pull off the control dials.
5 Using a 7 mm box spanner, remove the injectors and replace them with the correct ones (size numbers are stamped on the inside, eg 70=0.70 mm). Hold on to the card housing the replacement injectors for later use.
