INSTALLATION
7 The operation of the regulator can be confirmed by connecting a manometer to the pressure test
point located on the side of the regulator body adjacent to the outlet. With the appliance operating
check the outlet pressure
• when all burners of the appliance are operating at maximum,
• when the smallest burner of the appliance is operating at minimum.
Under these conditions the outlet pressure should not vary from the nominal outlet pressure of
2.60kPa by more the +0.52kPa.
8 If the regulator appears to not be performing satisfactorily then check the following points.
• If the outlet pressure is consistently too low then the inlet pressure may be too low and
adjustment of an upstream regulator may be needed, or an upstream regulator or valve with
insufficient flow capacity may be present in the gas supply line. If this is suspected then it may
be necessary to repeat the checks whilst measuring both the inlet and outlet pressure to
determine if the inlet pressure is in the range 2.75 – 7.00kPa.
• Check that the insert has been fitted correctly as per diagram figure 8. Check that the
turret screw is fully screwed down.
• Check that the regulator has been fitted to the gas supply line in the correct orientation, the
arrow on the base of the body indicates the director of gas flow.
Once these checks have been completed, if the regulator still fails to perform in a satisfactory manner
it should be replaced.
9 One by one, turn the knobs to minimum and screw in the bypass screw (accessible when the
knob is removed) until a small stable flame results. Turn the knob to maximum and then back to
minimum to ensure that the correct minimum flame is maintained.
10 Attach the LPG sticker to the cooker, near the gas supply inlet. Cover the Natural Gas label that is
factory fitted.
