Candy PR 2250 GH - Manual (Page 21)

Regulating the minimum flame
After lighting the burners, turn the control knob to the minimum setting and then remo-
ve the knob (this can easily be removed by apply a gentle pressure).
Using a small «Terminal» type screwdriver the regulating screw can be adjusted as in
Fig. 8. Turning the screw clockwise reduces the gas flow, whilst turning it anticlockwise
increases the flow – Use this adjustment to obtain a flame of approximately 3 to 4 mm
in length and then replace the control knob.
If GPL (cylinder) gas is being used, turn the screw clockwise right to the end of the
travel of the by-pass.

When you have carried out the new gas regulation, replace the old gas rating pla-
te on your appliance with one (supplied with hob) suitable for the type of gas for
which it has been regulated.

Adapting the hob to different types of gas
To adapt the Hob for use with different types of gas, carry out the following instructions:
— remove the grids and burners
— insert the hexagonal spanner (supplied) into the burner support (Fig. 5)
— unscrew the injector and replace it with one suitable for the gas to be used (see
Table of gas consumption)
— carry out regulation of the burner.

Regulating the burners
For maximum efficiency from the burners, the correct combustion of the flame is neces-
sary (see table of gas consumptions quota “X”). A good flame must be well aligned and
without yellow tips (Fig. 7/B). If there is insufficient air, the flame will be uneven with yel-
low tips (Fig. 7/A). If there is too much air, the flame will be very short and bright (Fig.
7/C). In these cases the combustion
must be adjusted by re-fitting the carburation tube to the Venturi (where there is insuffi-
cient air) or removing the carburation tube (in the case of too much air). To position the
carburation tube, the fixing screws must be loosened, and retightened when the sati-
sfactory combustion is obtained.
