Jenn-Air JES9800 manual Downdraft Ventilation System, Home Canning, Cookware Characteristics

■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.
