TESTING THE OPERATION OF THE GAS COOKER
NOTE: 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 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.
