26 INSTALLING THE GAS ELEVATED COOKER
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.
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.
INSTALLING THE GAS ELEVATED COOKER GAS CONVERSION PROCEDURE
10. Re-fit oven supply pipe to burner and replace
the backpanel.
11. Place gas sticker supplied onto rear panel over
existing sticker.
12. Remove the regulator and replace with test point
adaptor supplied for ULP or propane. For NG
remove test point adaptor and replace with regulator
supplied. Note that ULP and propane both use the
same test point adaptor.
13. Turn on gas & check for leaks.
14. Check and adjust the test point pressure according
to the procedure in the installation instructions.
15. Light all burners and operate at maximum.
16. For each hotplate and grill burner adjust the burner
to minimum and screw in the bypass screw until
a small stable flame results. Adjust the burner to
maximum and back to minimum to ensure correct
adjustment.
17. Re-fit the control panel & re-connect to electrical
power.
1. Turn off gas supply to appliance.
2. Disconnect appliance from electrical power
(if applicable).
3. Pull off control knobs and remove control panel
(two screws).
4. Remove grill burner injector and replace with
appropriate injector.
5. Fit aeration control (shutter) supplied to grill burner
as required. See page 10 of instruction book for
grill shutter assembly diagram. Note that ULP and
propane use the same aeration control.
6. Remove existing hotplate injectors and fit appropriate
injectors supplied.
7. Remove by pass screw in oven thermostat and fit
appropriate by pass screw supplied. Note that ULP
and propane use the same by-pass screw.
8. Remove backpanel and disengage oven supply pipe
from oven burner.
9. Remove oven injector and replace with injector
supplied.
