Testing the operation of the gas cooker

Checking gas supply
1. Check the manometer zero point is correct.
2. Connect the manometer to the cooker pressure test point. This is
located on the regulator or LPG inlet fitting.
3. Turn on the gas supply and the electricity 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.
4. Check the operating pressure for the particular gas type.
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 by more than ±20% of the nominal outlet
pressure (ie ±0.20kPa for Natural Gas).
If the regulator appears to not be performing satisfactorily then check
the following points.
1. 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.
2. 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.
NOTE: When flame is unsatisfactory, then refer to the Electrolux
Technical Publications and correct the fault, if possible.
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:
1. 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.
2. Check the ignition on all burners both separately and in
combination.
3. Check the operation of the electrical components, if applicable.
4. 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.
NOTE: If the cooker cannot be adjusted to perform correctly, then
inform the customer of the problem and put a warning notice on the
cooker. If the problem is dangerous, then disconnect the cooker. If
there is a fault, then the customer should be advised to contact the
manufacturer's local service organisation or the retailer.
