9Note: Flat-bottomed canners arerequired for glass cooktops.Pots that extend beyond 1″ ofthe surface unit’s circle are notrecommended for most surfacecooking. However, when canningwith water-bath or pressure canner,larger-diameter pots may be used.This is because boiling watertemperatures (even under pressure)are not harmful to the cooktopsurfaces surrounding the surface units.HOWEVER, DO NOT USE LARGE-DIAMETER CANNERS OR OTHERLARGE-DIAMETER POTS FORFRYING OR BOILING FOODSOTHER THAN WATER. Most syrupor sauce mixtures—and all types offrying—cook at temperatures muchhigher than boiling water. Suchtemperatures could eventually harmthe glass cooktop surfaces.Be sure the canner fits over thecenter of the surface unit. If yourcooktop or its location does notallow the canner to be centeredon the surface unit, use smaller-diameter pots for good canningresults.Flat-bottomed canners must beused. Do not use canners withflanged or rippled bottoms (oftenfound in enamelware) becausethey don’t make enough contactwith the surface units and takea long time to boil water.When canning, use recipes andprocedures from reputablesources. Reliable recipes andprocedures are available from themanufacturer of your canner;manufacturers of glass jars forcanning, such as Ball® and Kerr®brand; and the United StatesDepartment of AgricultureExtension Service.Remember that canning is aprocess that generates largeamounts of steam. To avoid burnsfrom steam or heat, be carefulwhen canning.NOTE: If your house has low voltage,canning may take longer than expected,even though directions have beencarefully followed. The process time willbe shortened by:(1) using a pressure canner, and( 2) starting with HOT tap water for fastestheating of large quantities of water.CAUTION: Safe canning requires that harmfulmicroorganisms are destroyed and thatthe jars are sealed completely. Whencanning foods in a water-bath canner,a gentle but steady boil must bemaintained for the required time. Whencanning foods in a pressure canner, thepressure must be maintained for therequired time. After you have adjusted the controls,it is very important to make sure theprescribed boil or pressure levels aremaintained for the required time. Since you must make sure to processthe canning jars for the prescribedtime, with no interruption in processingtime, do not can on any cooktopsurface unit if your canner is not flat.Observe the Following Points in CanningWrong!Right!www.GEAppliances.comSafety Instructions Operating Instructions Care and Cleaning Troubleshooting Tips Consumer Support
