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″ (5.1 x 10.2 cm) 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.
• Some models have a pocket handle. If installing the microwave near a right side wall, make sure there is at least 3 inches of clearance between the wall and the microwave oven so 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 the “Rectangular to Round Transition” illustration in the “Venting Design Specifications” section.

Installation Dimensions
NOTE: The grounded 3 prong outlet must be inside the upper cabinet. See the “Electrical Requirements” section.

*30″ (76.2 cm) is typical for 66″ (167.6 cm) installation height. Exact dimensions may vary depending on the type of range/cooktop below.
NOTE: To ensure good performance, do not obstruct top vent airflow. If cabinets are deeper than 14″ (35.6 cm) but no more than 15″ (38.1 cm), use the bump-out mounting kit to replace the I bar mounting plate from the wall. The bump-out mounting kit (part # W11185746) is not provided but can be purchased from Whirlpool.

VENTING DESIGN SPECIFICATIONS

This section is intended for architectural designers and builders/ contractor reference only.
NOTES:
■ Vent materials needed for installation are not provided with microwave hood combinations.
■ We do not recommend using a flexible metal vent.
■ To avoid possible product damage, be sure to vent air outside unless using recirculation installation. Do not vent exhaust air into concealed spaces, such as spaces within walls or ceilings, attics, crawl spaces or garages.
For optimal venting installation, we recommend:
■ Using roof or wall caps that have backdraft dampers.
■ Using a rigid metal vent.
■ Using the most direct route by minimizing the length of the vent and number of elbows to provide efficient performance.
■ Using uniformly sized vents.
■ Using duct tape to seal all joints in the vent system.
■ Using caulking compound to seal exterior wall or roof opening around cap.
■ Not installing 2 elbows together, for optimal hood performance.
If venting through the wall, be sure that there is proper clearance within the wall for the damper to open fully.
If venting through the roof, and the rectangular-to-round transition is used, be sure there are at least 3″ (7.6 cm) of clearance between the top of the microwave oven and the transition piece. See “Rectangular-to-Round Transition” illustration.
Rectangular-to-Round Transition
NOTE: The minimum 3″ (7.6 cm) clearance must exist between the top of the microwave oven and the rectangular-to-round transition piece so that the damper can open freely and fully.
A. Roof cap
B. 6″ (15.2 cm) min. diameter round vent
C. Elbow (for wall venting only)
D. Wall cap
E. 3 1 ⁄4″ x 10″ to 6″ (8.3 x 25.4 cm to 15.2 cm) rectangular-to-round transition piece
F. Vent extension piece, at least 3″ (7.6 cm) high

Recommended Standard Fittings
The following length equivalents are for use when figuring vent length. See the examples in “Recommended Vent Length.”

A. Rectangular-to-round transition piece: 3 ¼” x 10″ to 6″ = 5 ft (8.3 x 25.4 cm to 15.2 cm = 1.5 m)
B. Roof cap: 3 ¼” x 10″ = 24 ft (8.3 x 25.4 cm = 7.3 m) C. 90° elbow: 3 ¼” x 10″ = 25 ft (8.3 x 25.4 cm = 7.6 m)
D. 90° elbow: 6″ = 10 ft (15.2 cm = 3 m)
E. Wall cap: 3 ¼” x 10″ = 40 ft (8.3 x 25.4 cm = 12.2 m)
F. 45° elbow: 6″ = 5 ft (15.2 cm = 1.5 m)
G. 90° flat elbow: 3 ¼” x 10″ = 10 ft (8.3 x 25.4 cm = 3 m)

Recommended Vent Length

A 3¼” x 10″ (8.3 x 25.4 cm) rectangular or 6″ (15.2 cm) round vent should be used.
The total length of the vent system including straight vent, elbow(s), transitions and wall or roof caps must not exceed the equivalent of 140 ft (42.7 m) for either type of vent. See the “Recommended Standard Fittings” section for equivalent lengths.
For best performance, use no more than three 90° elbows. To calculate the length of the system you need, add the equivalent lengths of each vent piece used in the system. See the following examples:

3¼” x 10″ (8.3 x 25.4 cm) vent system = 73 ft (22.2 m) total

A. One 3 ¼” x 10″ (8.3 x 25.4 cm) 90° elbow = 25 ft (7.6 m)
B. 1 wall cap = 40 ft (12.2 m)
C. 2 ft (0.6 m) + 6 ft (1.8 m) straight = 8 ft (2.4 m)

6″ (15.2 cm) vent system = 73 ft (22.2 m) total

A. Two 90° elbows = 20 ft (6.1 m)
B. 1 wall cap = 40 ft (12.2 m)
C. 1 rectangular-to-round transition piece = 5 ft (1.5 m)
D. 2 ft (0.6 m) + 6 ft (1.8 m) straight = 8 ft (2.4 m)
If the existing vent is round, a rectangular to round transition piece must be used. In addition, a rectangular 3″ (7.6 cm) extension vent between the damper assembly and a rectangular to round transition piece must be installed to keep the damper from sticking.
