b. Any conversion required must be performed by your dealer or a qualied
licensedtechnicianorgasservicecompany.Pleaseprovidetheserviceperson
withthismanualbeforeworkisstartedonthecooktop.(Gasconversionsarethe
responsibilityofthedealerorenduser.)
c. Thiscooktopcanbeused with NATURALor LP/PROPANE gas. It is shipped
fromthefactoryadjustedforusewithNATURALgas.
d. Manifoldpressureshouldbecheckedwithamanometer;NATURALgasrequires
4.0”W.C.P.andLP/PROPANErequires11.0”W.C.P.(seegurebelow).
• Incoming line pressure upstream from the regulator must be 1” W.C.P.
higherthanthemanifoldpressureinordertochecktheregulator.
• Theregulatorusedonthiscooktopcanwithstandamaximuminputpressure
of1/2PSI(14.0”W.C.P).Ifthelinepressureisinexcessofthatamount,a
step-downregulatorwillberequired.
e. The appliance, its individual shut-off valve, and pressure regulator must be
disconnectedfromthegassupplypipingsystemduringanypressuretestingof
thatsystematpressuresinexcessof1/2PSI(3.5kPa).
f. Theappliancemustbeisolatedfromthegassupplypipingsystembyclosingits
individualmanualshut-offvalveduring anypressure testingof thegas supply

3.FlexibleConnections:
Iflocalcodespermit,CSAorULdesign-certied,exiblemetalapplianceconnectoris
recommendedforconnectingthiscooktoptothegassupplyline.DoNotkinkordamage
theexibleconnectorwhenmovingthecooktop.Thepressureregulatorhas3/8”NPT
femalepipethreads.Youwillneedtodeterminethettingsrequired,dependingonthe
sizeofyourgassupplyline,exiblemetalconnectorandshutoffvalve.
4.RigidPipeConnections:
Ifrigidpipeisusedasagassupplyline,acombinationofpipettingsmustbeused
toobtainanin-lineconnectiontothecooktop.Allstrainsmustberemovedfromthe
supplyandfuellinessocooktopwillbelevelandinline.
• Use joint compounds and gaskets that are resistant to action of natural or
propanegasonallmalepipethreads.
• Do not over tighten gas tting when attaching to pressure regulator. Over
tighteningmaycrackregulator.
5.LeakTesting:
IMPORTANT:Leaktestingoftheapplianceshallbeconductedasfollows:
• After nal gas connection is made, turn on manual gas valve and test all
connectionsingassupplypipingandapplianceforgasleakswithasoapywater
solution.Duringthistestallappliancegasvalveshavetobeclosed.
• Inordertoavoidpropertydamageorseriouspersonalinjury,neveruseaIighted
match.Ifaleakispresent,tightenjointorunscrew,applymorejointcompound,
tightenagainandretestconnectionforleak.

OPERATIONS TO BE PERFORMED WHEN
SUBSTITUTING THE INJECTORS
• Removethepansupports,theburnercapsandtheflame
spreaders.
• Using a wrench substitute the nozzle injectors “J1”, “J2”
and“J3”(figs.2.6a,2.6b)withthosemostsuitableforthe
kindofgasforwhichitistobeused.
• Refit the flame spreaders, the burner caps and the pan

The burners are conceived in such a way so as not to
requiretheregulationoftheprimaryair.
SETTING THE BURNER MINIMUM
Whenswitchingfromonetypeofgastoanother,theminimum
owratemustalsobecorrect:theameshouldnotgoouteven
whenpassingsuddenlyfrommaximumtominimumame.
Toregulatetheamefollowtheinstructionsbelow:
• Lighttheburner.
• Setthegasvalvetotheminimumrateposition.
• Removetheknob.
• With a thin screwdriver, turn the regulation screw “A”
