Installation instructions
Adjusting the minimum burner setting
This has been adjusted at the factory for Natural Gas but may need adjusting for local
conditions.
When converting to LPG, the minimum setting MUST be re-adjusted for each burner.
To adjust the minimum setting, you will need a Ø 2.5 x 45 mm screwdriver.
1
Light the burner and set the control dial to its minimum.
2
Remove the dial.
3
Slowly turn the adjustment screw inside the valve shaft until a minimum regular flame is
achieved. Note:
The flame will diminish when the screw is turned clockwise, and increase when turned
anti-clockwise.
The brass wok burner in the centre of CG905DWAC models may require progressive
venturi adjustment (Fig. 6) until a good flame (Fig.4) is achieved:
- If the flame is ‘lifting off’ the burner, move the venturi closer to the injector.
- If there is yellow tipping, move the venturi away from the injector.
4
Refit the dial.
5
Check the minimum burner setting: quickly turn the dial from maximum to minimum. The flame
must not go out. If it does, repeat the steps above.
Repeat the steps above for each burner.
