11Simmering Your new professional gas range hasexceptionally low simmering capabilities. Thecenter simmer cap serves as a heat diffuser tospread out the heat to avoid having a center hotspot. Keep in mind that because of the high heatcapacity of the outer burner, and the mass of thecast iron burner grates (they retain heat longerthan lighter, conventional grates), some foodsmay continue to cook by retained heat after theburner has been turned off.The simmer burner is lit from the outside burnerflame.The flame travels through the simmer ignitionchannels and crosses over onto the simmerburner located just beneath the simmer cap.When lighting only the simmer burner, alwayslight the main burner first. This will in turnprovide the ignition source for the simmerburner. Ensure that the simmer ports are litbefore turning the control knob down to thesimmer position. Should a strong draft orboilover extinguish the simmer flame it will notrelight automatically as the outer burner would.SimmerignitionchannelsBurner baseElectronicignitorsNOTE: Keep the ignitor, ignitor cap and burnerports clean.If a burner does not ignite, listen for theclicking sound. If the ignitor is not clicking,turn off the burner. Check the circuit breakerfor a blown fuse or a tripped circuit breaker. Ifthe ignitor still fails to operate, check theProblem Solver in the back of this guide or thePower Failure information in this section.NOTE: If you are using propane gas, a slight popor flash may occur at the burner ports a fewseconds after the burner has been turned off.This “extinction pop” is normal for propane gas.Burnerefficiencyand flamecharacteristicsThe burner flame should burn completelyaround and within the burner with no excessivenoise or lifting. The flame should be blue incolor and stable with no yellow tips.An improper air-gas mixture may cause eithera burner flutter or a yellow-tipped flame.A technician should adjust the flame.During initial use, foreign particles in the gasline, or dust in the air or around the appliancemay cause an orange flame. This will disappearwith use.IgnitorPowerfailureThe electric ignition that lights the surfaceburners will not operate during a power failure.To light the surface burners during a powerfailure, turn the control knob for the burneryou want to light to LITE while holding alighted match to the outer ring.After the flame is burning all the way aroundthe burner, adjust the flame.It is necessary to light each burner separatelyeach time you want to use it during a powerfailure.
