Kitchen Design

Kitchen design is one area where Jenn Air® truly rises above Thermador®. Most cooking appliances, including Thermador®, require overhead hoods for ventilation. This limits where designers can put the range without major renovations. The innovative solution brought about by Lou Jenn in 1965 allows kitchen designers to put the range almost anywhere while maintaining a sleek and elegant style. Jenn Air® ranges do not require overhead hoods for ventilation.

How Downdraft Venting Works

How does a Jenn Air® range remove smoke and odors without an overhead vent? The downdraft venting of a Jenn Air® range works vent that is located behind the range. The design is similar to the vent for your dryer. The vent rises from the backside of the range. A fan blows air at a height of 19”, and traps smoke and odors. The fan moves the air into a curved vent in the range and out through a wall vent behind the range.

The controls for the Jenn Air® downdraft system are concealed in the cooktop. There are four settings for the fan. When you turn on the system, a unit rises up from the range top. You can turn it on manually or program the unit to work at certain times of the day. The system has an automatic shutoff that stops the fan, and retracts the unit back into the stovetop.

Burner Design

Jenn Air® ranges are made with a double stack of brass that is precisely drilled with holes for gas cooking. The burner design allows for impressive temperature control, whether you need a low, slow simmer, or high heat for searing.

Thermador® ranges feature a unique star-shaped burner design. The perimeter of the burner is 56% longer than a standard round burner. This means more cooking power in the same space.

Related Questions

What’s the difference between a range and a stove?

A range includes the stovetop and oven. A stove is just the cooktop. The words range and stove are often used interchangeably.

What is a steam oven?

Steam ovens use steam for cooking rather than electricity or gas. The benefits of a steam oven include better color to your foods and retaining nutrients. You use less oil for cooking with a steam oven, and the food stays moist.

Do indoor grills work as well as outdoor grills?

Indoor grills give you the convenience of grilling regardless of weather. The downside is that you cannot achieve the smokey flavor of an outdoor grill. Outdoor grills produce higher temperatures than indoor grills. Heat distribution is better with an indoor grill.

How does convection cooking work?

A convection oven circulates warm air around the food with a special exhaust and fan design. Convection is preferred by many cooks and bakers because it cooks food evenly in less time.
