Installation
Operation on SNG
For SNG, please contact Electrolux Customer Service.
Testing the gas cooker
warning
You MUST test the cooker after installation, before you hand it
over to the customer.
You MUST have a manometer and a connecting tube.
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) to ensure2.75kPa at inlet to
Appliance Gas Regulator.
• 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 these conditions the outlet pressure should
not vary from nominal operating pressure of 1.0kPa (for
Natural Gas) or 2.75kPa (for Propane and ULPG) by more
than ± 20% (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
flowcapacity may be present in the gas supply line. It may
benecessary to repeat the checks whilst measuring both
theinlet and outlet pressure to determine if the inlet pressure
is1.13 - 5kPa for NG, 2.75 - 7 kPa for Propane and
ULPG.
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.
Testing cooker features
• Observe the flame appearance on each burner. If it is
smaller or larger than expected, then the injector size
needs checking
• If the flame is unsatisfactory, then refer to the Electrolux
Technical Publications and correct the fault if possible
• When maximum flame appearance is correct, check the turn
down setting on each burner. If incorrect, proceed as follows:
warning
1. Disconnect electric power.
2. Remove the control panel and adjust the bypass screw
mounted on the body of each hotplate control cock.
3. Check the ignition on all burners both separately and in
combination.
4. Check the operation of the electrical components, if
applicable.
5. When operating correctly, show customer how to use the
cooker.
6. If not operating correctly, advise the customer to ring
Electrolux service. Place a warning sign on cooker or if
dangerous, disconnect cooker.
