Viking Installation Guide
IMPORTANT–Please Read and Follow!
•Please read all instructions thoroughly before installing the Built-In Microwave Hood. Two people are recommended to install this product.
•If a new electrical outlet is required, its installation should be completed by a qualified electrician before the Built-In Microwave Hood is installed. See ELECTRICAL GROUNDING INSTRUCTIONS on page 2.
Unpacking and Examining
Your Oven
Open the bottom of the carton, bend the carton flaps back and tilt the oven over to rest on plastic foam pad. Lift carton off oven and remove all packing materials, Wall and Top Cabinet Template, Turntable, and Turntable Support. SAVE THE CARTON AS IT MAY MAKE INSTALLATION EASIER.
•Remove the feature sticker from the outside of the door, if there is one.
•DO NOT REMOVE THE WAVEGUIDE COVER, which is located on the right side wall of the oven cavity. Check to see that there is a Wall TEMPLATE and Top CABINET Template. Read enclosures and SAVE the Use and Care manual.
Check the oven for any damage, such as misaligned or bent door, damaged door seals and sealing surfaces, broken or loose door hinges and latches and dents inside the cavity or on the door. If there is any damage, do not operate the oven and contact your dealer or Viking AUTHORIZED SERVICER.

Designer Built-In Microwave Hood
111 Front Street
Greenwood, Mississippi 38930 USA
2 Wall Construction
This Built-in Microwave Hood should be mounted against and supported by a flat vertical wall. The wall must be flat for proper installation. If the wall is not flat, use spacers to fill in the gaps. Wall construction should be a minimum of 2” x 4” wood studding and 3/8” or more thick dry wall or plaster/lath. The mounting surfaces must be capable of supporting a weight of 110 pounds—the oven and contents—AND the weight of all items which would normally be stored in the top cabinet above the unit. The unit should be attached to a minimum of one 2” x 4” wall stud.
To find the location of the studs, one of the following methods may be used:
•Use a stud finder, a magnetic device which locates the nails in the stud.
•Use a hammer to tap lightly across the mounting surface to find a solid sound. This will indicate stud location.
The center of the stud can be located by probing the wall with a small nail to find the edges of the stud and then placing a mark halfway between the edges. The center of any adjacent studs will normally be 16” or 24” to either side of this mark.
3ELECTRICAL GROUNDING
INSTRUCTIONS
This appliance must be grounded. This oven is equipped with a cord having a grounding wire with a grounding plug. It must be plugged into a wall receptacle that is properly installed and grounded in accordance with the National Electrical Code and local codes and ordinances. In the event of an electrical short circuit, grounding reduces risk of electric shock by providing an escape wire for the electric current.
WARNING: Improper use of the grounding plug can result in a risk of electric shock.
ELECTRICAL REQUIREMENTS
The oven is equipped with a 3-prong grounding plug. DO NOT UNDER ANY CIRCUMSTANCES CUT OR REMOVE THE GROUNDING PIN FROM THE PLUG.
DO NOT USE AN EXTENSION CORD.
If the power supply cord is too short, have a qualified electrician or serviceman install an outlet near the appliance.
The Power Supply Cord and plug must be connected to a separate 120 Volt AC, 60 Hz, 15 Amp, or more branch circuit, single grounded receptacle. The receptacle should be located inside the cabinet directly above the Built-in Microwave Hood mounting location as shown in figure 2.
NOTE:
•If you have any questions about the grounding or electrical instructions, consult a qualified electrician or serviceperson.
•Neither Viking nor the dealer can accept any liability for damage to the oven or personal injury resulting from failure to observe the correct electrical connection procedures.

4 Hood Exhaust Duct |
5 Tools Recommended for |
|
Installation |
When the hood is vented to the outside, a hood exhaust duct is required. All ductwork must be metal; absolutely do not use plastic duct. Check that all connections are made securely. Please read the following carefully:
EXHAUST CONNECTION: The hood exhaust has been designed to connect to a standard 3-1/4" x 10" rectangular duct. If round duct is required, a rectangular- to-round adapter must be used.
REAR EXHAUST: If a rear or horizontal exhaust is to be used, care should be taken to align the exhaust with the space between the studs, or wall should be prepared at the time it is constructed by leaving enough space between wall studs to accommodate exhaust.
MAXIMUM DUCT LENGTH: For satisfactory air movement, the total duct length of 3-1/4" x 10" rectangular or 6" diameter round duct should not exceed 140 feet.
Elbows, adapters, wall caps, roof caps, etc. present additional resistance to air flow and are equivalent to a section of straight duct which is longer than their actual physical size. When calculating the total length, add the equivalent lengths of all transitions and adapters plus the length of all straight duct sections. Figure 3 shows the approximate feet of equivalent length of some typical ductwork parts. Use the values in parentheses for calculating air flow resistance equivalent, which should total less than 140 feet.

1) MOUNTING OVEN TO THE WALL: Place carton upside down.
NOTE: Before insertion, be sure you leave a space more than the thickness of the wall between the Mounting Plate and the end of each of the Toggle Nuts (in the closed position). If you do not leave enough space, the Toggle Nut will not be able to open on the other side of the wall. Also, once a Toggle Nut opens, it cannot be withdrawn from the hole; therefore make sure all of the Toggles are in the correct position before insertion.
