Cookware; Home Canning - Whirlpool  WFG540H0AW Use & Care Manual

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
grates.
Cookware material is a factor in how quickly and evenly heat is
transferred, which affects cooking results.
Cookware with nonstick surfaces should not be used under the
broiler.
Check for 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.
When canning for long periods, alternate the use of surface
burners between batches. This allows time for the most recently
used areas to cool.
Center the canner on the grate above the burner.

For best results, the cookware should be centered above the
burner with the bottom sitting level on the grate. The flame should
be adjusted so that it does not extend up the sides of the pan.

Do not place canner on 2 surface burners at the same time.
