USING YOUR RANGE
Using the surface cooking areas
Home canning information
To protect your range:
Use flat-bottomed canners on all types of
cooktops,
especially
ceramic
glass.
Canners with
rippled or
ridged bot-
toms do not
allow good
contact with
the surface.
Center the canner over the largest surface
cooking area. Do not extend more than
one inch outside the surface cooking area.
Large diameter canners/pans, if not 
centered correctly, trap heat and can
cause damage to the cooktop.
Do not place your canner on two surface
cooking areas at the same time. 
The type of material the canner is made of
determines the length of heating time.
Refer to the “Characteristics of cookware
materials” chart later in this section for
more information.
When canning for long periods of time,
allow elements and the surrounding 
surfaces to cool down.
Alternate use of the surface cooking areas
between batches or prepare small batches at
a time.
Start with hot water, cover with a lid, and
bring to a boil; then reduce heat to 
maintain a boil or required pressure levels
in a pressure canner.
On coil element model, keep your reflector
bowls clean so that they will always reflect
heat well.
For up-to-date information on canning,
contact your local U.S. Government
Agricultural Department Extension Office
or companies who manufacture home
canning products.

Optional canning kit
(Coil element model)
Most water-bath or pressure canners have
large diameters. If you do canning with them
at high heat settings for long periods of time,
you can shorten the life of regular coil 
elements. This can also damage the 
cooktop. If you plan to use the cooktop for
canning, we recommend the installation of a
Canning Kit. Order the kit (Part No. 242905)
from your dealer or designated service 
company.
Cookware tips
Select a pan that is about the same size as
the surface cooking area. Cookware should
not extend more than 1 inch (2.5 cm) 
outside the area.
For best results and greater energy 
efficiency, 
use only flat-bottomed 
cookware that makes good contact with
the surface cooking area. Cookware with
rounded, warped, ribbed (such as some
porcelain enamelware), or dented bottoms
could cause uneven heating and poor 
cooking results.
Cookware designed with slightly indented 
bottoms or small expansion channels can
be used.
Cookware with a non-stick finish has
heating characteristics of the base material.
Check for rough spots on the bottom of
metal or glass cookware which will scratch
the ceramic glass surface.
Use flat bottom cookware for best heat 
conduction from the surface cooking area
to the cookware. Determine flatness with
the ruler test. Place the edge of a ruler
across the bottom of the cookware. Hold it
up to the light. No light should be visible
under the ruler. Rotate the ruler in all 
directions and look for any light.
Do not leave empty cookware, or cook-
ware which has boiled dry, on a hot surface
cooking area. The cookware could 
overheat, causing damage to the cookware
or the surface cooking area.
