Introduction
The Profile 30-in. Slide-In Induction Range with convection oven and warming drawer features electronic
oven and induction element controls. The induction elements provide unmatched cooking performance and
flexibility. Induction technology heats only the pan and its contents and offers energy efficiency by reducing
wasted heat when compared to radiant and gas cooktops.
The Profile 30-in. Slide-in Induction Range has the following new features:
• Innovative technology―delivers the responsiveness of a gas cooktop.
• Superior performance―induction technology heats only the pan and
its contents, providing an incredibly fast boil time.
• Remarkable versatility―this induction cooktop offers the choice of
19 different power levels, including a 3700-watt, 11" element for large
cookware , warming capability, and a low-heat simmer setting for
delicate sauces.
• Cooler cooktop surface―since there is not a traditional thermal
heating element, the induction cooktop stays cooler than conventional
radiant cooktops.
• Below cooktop venting―dissipates heat, permitting less depth to the
burner box.
• Easy cleanability―cooktop cleaning is easier since spills and splatters do not burn on the cooktop.
• Electronically controlled oven heating
elements―provide precise cooking control with
fast preheating.
• Convection mode uses reverse-air convection
technology―a bidirectional fan that works with
a dedicated third heating element to promote
even heat circulation.
• Performance compensation for 208-volt
installation―boosts power as needed in
multifamily dwellings.
• Cooktop locked out during self clean
• Hidden oven bake element―concealed
beneath the oven floor, allows quick and easy
ash removal following the self-clean cycle.
• Two nickel-plated sliding extension racks
