KitchenAid 30-Inch 4 Burner Downdraft Gas Cooktop, Architect® Series II Use & Care Manual

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.

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.

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.

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.

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.

Use the following chart as a guide for cookware material 
characteristics.
