Cook tops come in either electric or gas and are installed in a cut out area of the countertop or in an island. Below is a description on the main differences on each type of installation.
Electric models typically have flanges around the cook top that is used to support the unit in the countertop.
Gas fueled cook tops require a slightly different installation than the electric models. They do not have any flange for support and need to fit into a cutout or dropped section of the countertop and actually sit on the top of the cabinet frame. Be sure to order the correct cabinets and countertops that include a drop section.
Built-in Ovens:
A built-in oven is very like a slide in range except that it slides in to cabinet or an opening in the wall. Be sure to check that the oven will fit in to the cabinets by taking measurements before attempting to fit it in.
