INSTALLATION
CHECKING THE 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 (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.
4. Check the operating pressure for the particular gas type (see
'Gas Type' table).
• For LPG cookers: Adjust the regulator if necessary
(this may be remote from the cooker).
• For Natural Gas cookers: Regulators are supplied
pre-adjusted and configured by the component maker
for use with Natural Gas. The appliance installer is not
required to make an adjustment to obtain the correct outlet
pressure setting. An arrow on the base of the regulator
indicates the direction of the gas flow when the inlet and
outlet of the regulator are orientated correctly.
5. When the regulator has been fitted check for leaks from the
connections with soapy water.
CHECKING REGULATOR FUNCTION
With the appliance operating, check the outlet pressure:
1. When all the burners of the appliance are operating
at maximum.
2. When the smallest burner of the appliance is operating
at minimum.
Under both these conditions the outlet pressure should not
vary from nominal operating pressure of 1.0kPa
by more then ± 20% (ie ±0.20kPa for Natural Gas).
If the regulator does not appear to 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. 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.
3. Replace the regulator if it fails to perform after the checks.
INSTALLATION
TESTING BURNER PERFORMANCE
• Observe the flame appearance on each burner when set to
max. If it is smaller or larger than expected, then the injector
size needs checking (refer to table).
• When maximum flame appearance is correct, check
the turn down setting on each burner. If incorrect, proceed
as follows:
WARNING
WARNING
Disconnect electric power.
1. Remove the control panel and adjust the bypass screw when
valve is set to maximum. The screw is mounted on the body
of each hotplate control valve.
2. Check the ignition on all burners both separately and
in combination.
3. Check the operation of the electrical components,
if applicable.
4. When operating correctly, show customer how to use
the cooker.
5. If not operating correctly, advise the customer to ring
Electrolux Customer Service Centre. Place a warning sign on
cooker or if dangerous, disconnect cooker.
