General information

HOOD EXHAUST

NOTE: Read these next two pages only if you plan to vent your exhaust to the outside. If you plan to recirculate the air back into the room, proceed to page 11.

OUTSIDE TOP EXHAUST (EXAMPLE ONLY)

The following chart contains an example of one possible ductwork installation .

IMPORTANT: If a rectangular-to-round transition adaptor is used, the bottom corners of the damper will have to be cut to fit, using the tin snips, in order to allow free movement of the damper.

OUTSIDE BACK EXHAUST (EXAMPLE ONLY)

The following chart contains an example of one possible ductwork installation.

NOTE: For back exhaust, care should be taken to align the exhaust with the space between studs, or the wall should be prepared at the time it is constructed by leaving enough space between the wall studs to accommodate exhaust.
NOTE: If you need to install ducts, note that the total duct length of 3 ¼˝ x 10˝ rectangular or 6˝ diameter round duct should not exceed 140 equivalent feet.
Outside ventilation requires a HOOD EXHAUST DUCT. Read the following carefully.
NOTE: It is important that venting be installed using the most direct route and with as few elbows as possible. This ensures clear venting of exhaust and helps prevent blockages. Also, make sure dampers swing freely and nothing is blocking the ducts.

Exhaust connection:

The hood exhaust has been designed to mate with a standard 3 ¼˝ x 10˝ rectangular duct.
If a round duct is required, a rectangular-to-round transition adaptor must be used. Do not use less than a 6˝ diameter duct.

Maximum duct length:

For satisfactory air movement, the total duct length of 3 ¼˝ x 10˝ rectangular or 6˝ diameter round duct should not exceed 140 equivalent feet.

Elbows, transitions, wall and roof caps,

Present additional resistance to airflow and are equivalent to a section of straight duct which is longer than their actual physical size. When calculating the total duct length, add the equivalent lengths of all transitions and adaptors plus the length of all straight duct sections. The chart below shows you how to calculate total equivalent ductwork length using the equivalent length in feet of some typical ducts.

Step-by-step installation guide

PLACEMENT OF THE MOUNTING PLATE

A. REMOVING THE MICROWAVE OVEN FROM THE CARTON/REMOVING THE MOUNTING PLATE

1. Remove the installation instructions, Exhaust adaptor, filters, glass tray, and the small hardware bag. Do not remove the Styrofoam protecting the front of the oven.
2. Fold back all 4 carton flaps fully against carton sides. Then caresssfully roll the oven and carton over onto the top side. The oven should be resting in the Styrofoam.
3. Pull the carton up and off the oven.
4. Remove and properly discard plastic bags.
5. Remove the 2 screws from the mounting plate. This plate will be used as the rear wall template and for mounting.
   NOTE: You will have to reuse two screws in original loction of outcase after removing mounting plate.

B. FINDING THE WALL STUDS

1. Find the studs using one of the following methods:
   A. Stud finder–a magnetic device which locates nails.
   B. Use a hammer to tap lightly across the mounting surface to find a solid sound. This will indicate a stud location.

2. After locating the stud(s), find the stud’s center by probing the wall with a small nail to find the edges of the stud. Then, place a mark halfway between the edges. The center of any adjacent studs should be 16˝ or 24˝ from this mark.

3. Draw a line down the center of the studs.

THE MICROWAVE MUST BE CONNECTED TO AT LEAST ONE WALL STUD.

C. DETERMINING WALL PLATE LOCATION UNDER YOUR CABINET

Plate position – beneath flat bottom cabinet.

Draw a vertical line on the wall at the center of the 30˝ wide space. Tape the Rear Wall Template onto the wall so that the top of the template touches the bottom of the cabinet and the centerline on the template lines up with the line you drew on the wall.

Plate position – beneath recessed bottom cabinet with front overhang.

Plate position – beneath framed recessed cabinet bottom.

Draw a vertical line on the wall at the center of the 30˝ wide space. Tape the Rear Wall Template onto the wall so that the top of the template touches the bottom of the cabinet frame and the centerline on the template lines up with the line you drew on the wall.
Your cabinets may have decorative trim that interferes with the microwave installation. Remove the decorative trim to install the microwave properly and to make it level.

THE MICROWAVE MUST BE LEVEL.
Use a level to make sure the cabinet bottom is level.
Draw a vertical line on the wall at the center of the 30˝ wide space. Draw a second, horizontal line on the wall below the cabinet to mark how far the inside of the front overhang descends below the cabinet. Tape the Rear Wall Template onto the wall so that the top of the template touches the bottom of the horizontal line and the centerline on the template lines up with the vertical line.

D. ALIGNING THE WALL PLATE

CAUTION: Wear gloves to avoid cutting fingers on sharp edges.

1. Draw a Horizontal line on the wall at the bottom of the “Rear Wall Template”.

2. Drill ⅝˝ holes for toggle bolts in 3 locations (Hole A, Hole B, Hole C) as shown in the illustration above. If the location of a hole lines up with a stud, drill a 3/16˝ hole for a wood screw. You cannot use a toggle bolt to attach the wall plate to a stud.
   NOTE: DO NOT MOUNT THE PLATE AT THIS TIME.

3. Holes A, B and C are inside area E. If none of these holes line up with a stud, find a stud in area E that lines up with a hole circle in Area E, and then drill a 3/16˝ hole into it for a wood screw. You must have at least one wood screw mounted firmly into a stud to support the weight of the microwave. Set the mounting plate aside.
