SERVICING AND MINOR ADJUSTMENTS
All service work, minor or not, must be performed by a suitably qualified and licensed person.
9.1
Setting Gas Pressure
A pressure test point is provided on the pressure regulator (for Natural Gas models) or on the inlet adapter (for ULPG
models) at the gas connection point of the appliance. The pressure should be set with one burner fully on. The set
pressure should be 1 kPa for Natural Gas or 2.75 kPa for ULPG.
9.2
Gas Simmer Flame Adjustment
The minimum gas flow for each burner is factory set but can be adjusted if necessary. The minimum flow can be increased or
decreased by:–
For models fitted with valves which have solid control shafts, removing the control knob and hob if necessary to gain access
to the adjustment screw on the valve body, and then turning the adjustment screw using a small flat bladed screwdriver. Take
care not to damage the head of the screw.
For models fitted with valves which have hollow control shafts, removing the control knob/s and turning the adjustment
screw in the centre of the control shaft using a small flat bladed screw driver. Take care not to damage the head of the screw.
Conversion from Natural Gas to ULPG: CG29, CG29WOK, CG60WOKFFE, CG90WOKFFE
THE FOLLOWING MUST BE CARRIED OUT BY AN AUTHORISED PERSON
General Information
The hob is supplied pre-adjusted for Natural Gas.
1. The injectors required for adapting this appliance to ULPG are supplied in the conversion kit P/N 51687-1 (CG29),
51687-2 (CG29WOK) and 51688 (CG60 & 90).
2. When the appliance has been converted to ULPG tick the box on the injector information label P/N 51665 (CG29 models)
or 51686 (CG60 and 90).
3. Change the black Natural Gas labels to the red ULPG labels.
Conversion
1. Remove the pan support Burner caps, burner ring/dress rings.
2. Remove the fitted injectors one by one and replace with the ULPG injector sized as the label P/N 51665 (CG29 models) or
51686 (CG60 & 90) attached to the appliance and also the users manual.
3. Fit the Test Point Adaptor at the gas inlet.
4. Replace all the burner parts ensuring that they are correctly keyed to the mating part.
5. After fully leak testing and working on each burner in turn, remove the control knob and light the burner and then adjust
the minimum flame via the adjustment screw in the centre of the Gas Cock shaft. With the gas cock set in the low flame
position, turn the adjustment screw clockwise to reduce the flow to the required level. Other burners should be full on
while adjusting a burner on the CG29. Two burners should be on full while adjusting a burner on the CG60 or CG90.
