Surface Grates
The grates must be properly positioned before cooking. In the
proper position the grates should be flush and level. Improper
installation of the grates may result in chipping or scratching of
the cooktop.
To ensure proper positioning, align bumpers on grate bottom with
the indentations in the cooktop. See cooktop illustrations in the
“Parts and Features” section for proper grate positioning.
Although the burner grates are durable, they will gradually lose
their shine and/or discolor due to the high temperatures of the
gas flame.
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 U se:

Turn vent fan knob clockwise to LOW or HIGH. Turn vent fan
knob to OFF when finished cooking, or when the cooktop is not
in use.
Home Canning
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.
■Do not place canner on 2 surface burners at the same time.
■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. 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.
