Electric and Gas Ranges, Cook-tops, and Ovens
The domestic range was designed as a multipurpose cooking appliance. It consists of a surface area with healing elements on the top to cook the food. The oven cavity is used for baking food at a set temperature. Within the same oven cavity, the broiling of food is also incorporated. Domestic ranges are available in either electric or gas, in sizes ranging from 20 inches to 48 inches in width, and with a wide selection of configurations and colors. The following sections describe a few of the common configurations available to the consumer.
The freestanding range stands between two base cabinets, or sometimes at the end of a cabinet line. The consumer has a choice of gas or electric. These ranges are available in 20- , [ 24 , 30- , 36- , 40- , and 48-inch widths (Figure 1-1). Some 40- and 48-inch models have two ovens. Designs include gas burners and gas ovens, or standard electric heating elements with electric ovens, and a glass cook-top with concealed electric elements underneath. Also available is a combination of electric and gas cooking. The controls might be located on the rear console or across the front

Designs include gas burners, standard electric heating elements, and a glass cook-top with concealed electric elements underneath. The oven and cook-top controls are usually located across the front of the range; however, some models have the cook-top controls along the side.

These ranges can also be installed overlapping the adjacent countertop edges, thereby eliminating dirt-catching gaps. A drop-in range either hangs from a countertop or sits on a low cabinet base; a slide-in range sits on the floor. Slide-in ranges and drop-in ranges (Figure 1-3) have the following advantages and disadvantages:
