ThisapplianceissuppliedsetuptoforNaturalGas
usage.Aconversionkitisincludedwiththeproduct
forUniversalLPGusage.Theconversionkitcontains6
injectorsand1LPGsticker.
Pleasefollowtheprocedurebelowifaconversiontosuit
UNIVERSALLPGisrequired.
1. Removethehotplatetrivets,burnercapsandburner
crownstoaccessthehotplateinjectors.Replacethe
factoryfittedinjectorswiththeappropriateinjectors,as
supplied.Refertoinjectororificetableforinjectorsizes.
Theinjectorsizeisstampedonthesideoftheinjector.
2. Unscrewthehexnutfromtheregulator.Thehexnut,brass
washerandnyloninsertwilldisengageasanassembly.
3. Unclipthenyloninsertfromthenutassemblyby
rotatingtheinsert1/4turn,andpullingitfree.
4. Turnovertheinsert,andclipbackintoposition.
5. Refitthehexnutassemblytotheregulatorensuringthat
itisfullyscreweddown.Theregulatorisnowsetfor
connectiontoLPG.
