If you have a square finish (flat) countertop and the opening width is 30" (76.2 cm), no countertop preparation is required.
Formed front-edged countertops must have molded edge shaved flat ³⁄₈" (1.0 cm) from each front corner of opening.Tile countertops may need trim cut back ³⁄₈" (1.0 cm) from each front corner and/or rounded edge flattened.
If countertop opening width is greater than 30" (76.2 cm), adjust the ³⁄₈" (1.0 cm) dimension.
Countertop must be level. Place level on countertop, first side to side, then front to back. If countertop is not level, range will not be level. Range must be level for satisfactory baking conditions.
These measurements are for planning purposes only. As with any built-in appliance, never make cuts or modifications without having the item there from which to take measurements.
