*Equivalent lengths of duct pieces are based on actual tests and reflect requirements for good venting performance with any downdraft cooktop.

†Measure and list feet of straight duct used. Count and list the quantity of all other duct pieces for the “Number Used” of each type.

IMPORTANT:

For maximum efficiency, use the shortest and straightest duct run possible, with as few fittings as possible. For satisfactory performance, the duct run should not exceed 100 feet equivalent length.

Venting performance is improved by using larger diameter duct.

Should not exceed 100 feet.

If flexible metal ducting is used, all the equivalent feet values in the table should be doubled. The flexible metal duct should be straight and smooth and extended as much as possible.

DO NOT use flexible plastic ducting.

Vent installation should not exceed 100 feet equivalent length.

Blower is rated at 400 CFM at 0.1 inch of water back pressure.

JP989SKSS specifications

The GE JP989SKSS is a remarkable addition to the lineup of advanced kitchen appliances, specifically designed to cater to the cooking needs of modern households. This professional-grade range offers a unique blend of style, functionality, and innovative features that enhance the cooking experience.

One of the standout features of the GE JP989SKSS is its dual fuel capability. By combining the precision of a gas cooktop with the even baking performance of an electric oven, this appliance provides the best of both worlds. Home cooks can enjoy the instant heat and temperature control of a gas burner while benefiting from the consistent heat distribution of an electric oven, making it ideal for baking and roasting.

The cooktop is equipped with five burners, including a powerful 20,000 BTU tri-ring burner that can handle everything from delicate simmering to rapid boiling. This versatility allows users to prepare multiple dishes simultaneously, optimizing their cooking efficiency. Additionally, the burners are designed with heavy-duty cast iron grates that not only enhance durability but also provide a professional look and feel.

The oven of the GE JP989SKSS features a generous capacity that allows users to cook multiple dishes at once without sacrificing quality. It employs advanced convection technology, which circulates hot air throughout the oven for faster and more even cooking results. This capability is particularly advantageous for baking, ensuring that pastries rise beautifully and roasts cook thoroughly.

Another notable technology in this range is the edge-to-edge cooktop design. This feature provides a seamless surface, allowing for easy movement of pots and pans across the entire cooktop. Moreover, the surface is made from easy-to-clean stainless steel, making maintenance a breeze.

The GE JP989SKSS also offers smart features, allowing users to control their oven remotely through a smartphone app. This technology enables cooks to preheat the oven, set timers, and receive alerts, providing greater flexibility in managing meal preparation.

Safety is a priority with features like the auto shut-off capability, which automatically turns off the oven after a set period, preventing any potential hazards. The range also includes a self-cleaning function, simplifying the process of maintaining a spotless oven.

In summary, the GE JP989SKSS stands out due to its dual fuel capability, powerful burners, convection baking technology, and smart home integration. This range is designed for those who seek both style and functionality, elevating the culinary experience in any kitchen. With its robust construction, innovative features, and user-friendly design, the GE JP989SKSS is a top-tier choice for home chefs.
