INSTALLATION
For LPG Cookers
Adjust the regulator if necessary (this may be remote from the cooker)
For natural gas cookers
• Check the manometer zero point is correct.
• Connect the manometer to the cooker pressure test point. This is located on the regulator or
LPG inlet fitting.
• Turn on the gas supply and the electricity (if applicable) and try to ignite the gas.
NOTE: It will take additional time to light the gas for the first time as air needs to be
purged from the pipes.
• Check the operating pressure for the particular gas type (see table).
Checking the Function of the Regulator
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
1.0kPa by more than ±20% of the nominal outlet pressure (±0.20kPa for Natural Gas).
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 1.13 – 5kPa.
• 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 direction of gas flow. Once these checks have
been completed, if the regulator still fails to perform in a satisfactory manner it should be
replaced.
Testing the cooker features
Observe the flame appearance on each burner. If it is much smaller or larger than expected,
then the injector size needs checking.
When maximum flame appearance is correct, then check the turn-down setting on each
burner. If the settings appear to be incorrect, proceed as follows:
• Adjust the bypass screw mounted on the body of each hotplate control cock. This is
accessible when the control knob and the control panel are removed.
• Check the ignition on all burners both separately and in combination.
• Check the operation of the electrical components, if applicable.
• If you are satisfied that the cooker is operating correctly, then turn it off and show the
customer how to use it.
Make sure you ask the customer to operate the clock and controls.
