Location Requirements Check the opening where the microwave oven will be installed. The location must provide: ■■ Minimum installation dimensions. See the "Installation Dimensions" illustration. ■■ Minimum one 2" x 4" (50.8 x 101.6 mm) wood wall stud and minimum 3/8" (1 cm) thickness drywall or plaster/lath within cabinet opening. ■■ Support for weight of 150 lbs (68 kg) which includes microwave oven and items placed inside the microwave oven and upper cabinet. ■■ Grounded electrical outlet inside upper cabinet. See the "Electrical Requirements" section. NOTES: ■■ If installing the microwave oven near a left sidewall, make sure there is at least 6" (15.2 cm) of clearance between the wall and the microwave oven so that the door can open fully. ■■ If installing the microwave oven near a right sidewall, make sure there is at least 3" (7.6 cm) of clearance between the wall and the microwave oven, so that you can grab the handle integrated inside the door. ■■ Some cabinet and building materials are not designed to withstand the heat produced by the microwave oven for cooking. Check with your builder or cabinet supplier to make sure that the materials used will not discolor, delaminate, or sustain other damages. Special Requirements For Wall Venting Installation Only: ■■ Cutout must be free of any obstructions so that the vent fit properly and the damper blade opens freely and fully. For Roof Venting Installation Only: ■■ If you are using a rectangular-to-round transition piece, the 3" (7.6 cm) clearance needs to exist above the microwave oven so that the damper blade can open freely and fully. See "Rectangular to Round Transition" illustration in the "Venting Design Specifications" section. ■■ For gas cooktops, we recommend that the combined cooking surface rating does not exceed 55,000 BTU/hr. NOTE: Depending on model, aluminum grease filter and charcoal filter may be combined. Materials Needed ■■ Standard fittings for wall or roof venting. See the "Venting Design Specifications" section. 2
