Venting Requirements

■ 36" (91.4 cm) model requires a 6" (15.2 cm) round vent

system. 48" (121.9 cm) model requires two 6" round vent

Vent system can terminate either through the roof or wall. To vent through a wall, a 90° elbow is needed.

roof cap

systems or a 10" (25.4 cm) round system using vent transition

kit number 4396915.

■ Vent system must terminate to the outside.

■ Do not terminate the vent system in an attic or other enclosed

area.

■ Do not use 4" (10.2 cm) laundry-type wall caps.

■ Use metal vent only. Rigid metal vent is recommended. Do

not use plastic or metal foil vent.

For the most efficient and quiet operation:

■ Use a straight run or as few elbows as possible.

■ Use no more than three 90° elbows.

■ Make sure there is a minimum of 24" (61 cm) of straight vent

between the elbows if more than one elbow is used.

■ Do not install two elbows together.

■ Use duct tape to seal all joints in the vent system.

Cold weather installations

An additional backdraft damper should be installed to minimize backward cold air flow and a nonmetallic thermal break to minimize conduction of outside temperatures as part of the vent system. The damper should be on the cold air side of the thermal break.

The break should be as close as possible to where the vent system enters the heated portion of the house.

Make up air

Local building codes may require the use of make-up air systems when using ventilation systems greater than specified CFM of air movement. The specified CFM varies from locale to locale.

Consult your HVAC professional for specific requirements in your area.

Calculating Vent System Length

To calculate the length of the system you need, add the equivalent feet (meters) for each vent piece used in the system.

Maximum equivalent vent length is 35 feet (10.7 meters) for 6" (15.2 cm) vent, 60 feet (18.3 m) for 10" (25.4 cm) vent.

Venting Methods

This canopy hood is factory set for venting through the roof or wall.

The 36" (91.4 cm) model requires a 6" (15.2 cm) round vent system for installation (not included). The 48" (121.9 cm) model requires two 6" (15.2 cm) round vent systems or a 10" (25.4 cm) round vent system for installation. The hood exhaust opening is 6" (15.2 cm) round.

NOTE: Flexible vent is not recommended. Flexible vent creates back pressure and air turbulence that greatly reduces performance.

RANGE HOOD LINER with INTERNAL BLOWER specifications

The KitchenAid Range Hood Liner with Internal Blower is a perfect combination of form and function, designed to enhance your kitchen's ventilation while maintaining a sleek appearance. This product stands out in the crowded marketplace for several reasons, most notably its high-performance features that cater to both the aesthetic and practical needs of modern cooking environments.

One of the main features of the KitchenAid Range Hood Liner is its internal blower system. This integral component operates quietly—reducing noise levels while delivering powerful ventilation. The internal blower efficiently removes smoke, steam, and cooking odors, keeping your kitchen fresh and comfortable. This technology eliminates the need for an external blower, streamlining installation and minimizing the complexity associated with traditional ventilation systems.

In terms of power, the range hood liner typically offers multiple fan speeds, allowing you to adjust the airflow based on your cooking habits. Whether you are simmering a delicate sauce or searing meat at high temperatures, the customizable speed settings ensure that you can effectively manage odors and heat without overwhelming noise. Additionally, many models feature a convenient delay-off option, which keeps the fan running after cooking is done, providing continued ventilation to clear lingering smells and humidity.

The design of the KitchenAid Range Hood Liner is equally impressive. It is constructed to fit seamlessly into cabinetry, giving your kitchen a sleek, integrated look. Made with premium materials such as stainless steel, the liner is not only durable but also easy to clean and maintain. Many models include dishwasher-safe filters that capture grease and particulates, ensuring your kitchen remains spotless while prolonging the life of your range hood.

Safety is also a priority with features such as the automatic shut-off, which prevents overheating and offers peace of mind during cooking sessions. Energy-efficient LED lighting is another characteristic that improves visibility over your cooking surface, making meal preparation safer and more enjoyable.

In summary, the KitchenAid Range Hood Liner with Internal Blower combines powerful performance, aesthetic charm, and innovative features, making it an excellent choice for both amateur cooks and culinary enthusiasts alike. With its advanced technology, durable design, and thoughtful safety features, it promises to elevate the functionality and ambiance of any kitchen space.
