Jenn-Air JES9900 Cooktop User Manual


 
7
Use flat-bottomed cookware for best heat conduction and
energy efficiency. Cookware with rounded, warped, ribbed or
dented bottoms could cause uneven heating and poor
cooking results.
Determine flatness by placing the straight edge of a ruler
across the bottom of the cookware. While you rotate the ruler,
no space or light should be visible between it and the
cookware.
Cookware designed with slightly indented bottoms or small
expansion channels can be used.
Make sure the bottoms of pots and pans are clean and dry
before using them. Residue and water can leave deposits
when heated.
To avoid damage to the cooktop, do not cook foods directly
on the cooktop.
Downdraft Ventilation System
The built-in downdraft ventilation system removes cooking
vapors, odors and smoke from foods prepared on the cooktop.
IMPORTANT: For optimal performance, operate downdraft
ventilation system with the filter properly installed.
To avoid the buildup of grease, the filter should be cleaned often.
For more information on proper filter placement and cleaning, see
“Downdraft Ventilation System” in the “General Cleaning”
section.
To Use:
The ventilation fan can be set to Low, High or Off.
Press VENT FAN once for Low, a second time for High, and a
third time to turn the fan Off.
Home Canning
When canning for long periods, alternate the use of surface
cooking areas, elements or surface burners between batches.
This allows time for the most recently used areas to cool.
Center the canner on the grate or largest surface cooking
area or element. On electric cooktops, canners should not
extend more than ½" (1.3 cm) beyond the surface cooking
area or element.
Do not place canner on 2 surface cooking areas, elements or
surface burners at the same time.
On ceramic glass models, use only flat-bottomed canners.
For more information, contact your local agricultural
department. Companies that manufacture home canning
products can also offer assistance.
Cookware
IMPORTANT: Do not leave empty cookware on a hot surface
cooking area, element or surface burner.
Ideal cookware should have a flat bottom, straight sides and a
well-fitting lid, and the material should be of medium-to-heavy
thickness.
Rough finishes may scratch the cooktop or grates. Aluminum and
copper may be used as a core or base in cookware. However,
when used as a base they can leave permanent marks on the
cooktop or grates.
Cookware material is a factor in how quickly and evenly heat is
transferred, which affects cooking results. A nonstick finish has
the same characteristics as its base material. For example,
aluminum cookware with a nonstick finish will take on the
properties of aluminum.
Cookware with nonstick surfaces should not be used under the
broiler.
Use the following chart as a guide for cookware material
characteristics.
COOKWARE CHARACTERISTICS
Aluminum
Heats quickly and evenly.
Suitable for all types of cooking.
Medium or heavy thickness is best for
most cooking tasks.
Cast iron
Heats slowly and evenly.
Good for browning and frying.
Maintains heat for slow cooking.
Ceramic or
Ceramic glass
Follow manufacturer’s instructions.
Heats slowly, but unevenly.
Ideal results on low to medium heat
settings.
Copper
Heats very quickly and evenly.
Earthenware
Follow manufacturer’s instructions.
Use on low heat settings.
Porcelain
enamel-on-
steel or cast
iron
See stainless steel or cast iron.
Stainless steel
Heats quickly, but unevenly.
A core or base of aluminum or copper
on stainless steel provides even
heating.
