Installation Instructions
(See page 5)
NOTE: IF INSTALLING HOOD WITH
WARMING SHELF PANEL, INSTALL
WARMING SHELF PANEL FIRST.
IMPORTANT - PLEASE READ AND FOLLOW
•Before beginning, please read these instructions completely
and carefully.
•Do not remove permanently affixed labels, warnings, or
plates from the product. This may void the warranty.
•Please observe all local and national codes and ordinances.
If no local codes are applicable, wire in accordance with the
National Electrical Code, ANSI/NFPA 70-1990.
•The installer should leave these instructions with the
consumer who should retain for local inspector’s use
and for future reference.
This hood is for residential installation only and is not
designed for installation over a commercial product. Make
sure power is off at the main circuit breaker or fuse box before
making connections. To avoid risk of fire, electric shock, or
injury to persons, turn off the electricity to the hood from
the power supply before servicing or cleaning.
Viking hoods are equipped with variable speed controls
for blowers. These units will not function with a single
speed ventilator. All Viking ventilator kits are designed
specifically for use with Viking hoods. Use of any non-
Viking ventilator kit will void the hood warranty.
WARNING
TO REDUCE THE RISK OF FIRE, ELECTRICAL SHOCK,
OR INJURY TO PERSONS, OBSERVE THE
FOLLOWING:
1. Installation work and electrical wiring must be done by
qualified person(s) in accordance with all applicable
codes and standards, including fire-rated construction.
2. Sufficient air is needed for proper combustion and
exhausting of gases through the flue (chimney) of fuel
burning equipment to prevent back drafting. Follow the
heating equipment manufacturer’s guideline and safety
standards such as those published by the National Fire
Protection Association (NFPA), and the American Society
for Heating, Refrigeration and Air Conditioning Engineers
(ASHRAE), and the local code authorities.
3. When cutting or drilling into wall or ceiling, do not
damage electrical wiring and other hidden utilities.
4. Ducted fans must always be vented to the outdoors.
5. WARNING!: To reduce the risk of fire, use only metal
ductwork.
6. CAUTION!: To reduce risk of fire and to properly
exhaust air, be sure to duct air outside. Do not vent
exhaust air into spaces within walls or ceilings, or into
attics, crawl spaces, or garages.
CAUTION
For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.
WARNING
TO REDUCE THE RISK OF FIRE, ELECTRICAL
SHOCK, OR INJURY TO PERSONS, RANGEHOODS
MUST BE INSTALLED WITH THE VENTILATORS
THAT ARE SPECIFIED ON THEIR CARTON
INDICATING SUITABILITY WITH THIS MODEL.
OTHER VENTILATORS CANNOT BE SUBSTITUTED.

•Maximum duct run length: 50 Ft. (152.4 cm)
•All CFM’s stated are based on tests with .1 static pressure; without applying static pressure (as some brands consciously do), CFM
could be greatly overstated.
•Duct run length is for general reference only; for longer duct runs, increase duct size and contact a qualified and trained installer.
•Straight runs and gradual turns are best; avoid sharp turns; for example, each 900elbow is equivalent to 5 - 10 feet (1.52 m - 3.05
m) of straight run.
•NEVER USE FLEXIBLE DUCT; It creates back pressure / air turbulence and greatly reduces performance.
•Proper performance is dependent upon proper ducting; make sure that a qualified and trained installer is used.
•Check with a qualified and trained installer or local codes for makeup air requirements, if any.

HEIGHT OF HOOD
The bottom of the hood should be 30” (76.2 cm)
min. to 33” (83.8 cm) max. above the countertop. This
would result in the bottom of the hood being 66” (167.6
cm) to 69” (175.3 cm) above the floor. These dimensions
provide for safe and efficient operation of the hood and a
more proportionately pleasing and attractive installation.

INSTALLATION
Plan where and how the ductwork will be located. Install
proper-sized duct work, transition(s), elbow(s) and roof or
wall cap.
Dimensions for the most common installations are shown
ABOVE.
Adjust your measurements for various heights of ceilings,
soffits, cabinets, or cooktops.
Roof Cap
7” Round
Duct
INSTALLING HOOD
Center hood over location and hold it against
bottom of soffit or flue. Secure hood to wall with
mounting screws.
Use additional mounting screws and wall anchors if
necessary.
NOTE: BECAUSE OF THE WEIGHT OF THE
HOOD - MAKE SURE THAT THE SCREWS ARE
DRIVEN INTO THE SOFFIT FRAMING AND NOT
JUST THE DRYWALL.

INSTALLING DUCT
1. Use 7” round ductwork. Run ductwork from roof cap or wall cap, to the installation location. For best
performance, use the straightest possible duct run and the fewest number of elbows. Tape all joints.
2. Run 120 VAC electrical power cable from service panel to installation location.
3. Connect transition provided to the damper on top of hood. Tape all joints.
4. Connect the same transition to the duct extending from the roof/wall cap. Tape all joints.
5. Remove wire box cover. Remove a knockout from the wiring box. Feed 6” of power cable through opening and
attach cable to wiring box with appropriate connector.
6. Wire black to black, white to white, and green or bare wire beneath green ground screw. Replace wire box cover.
7. If using a duct cover, from inside the hood, attach duct cover to top of hood using the screws provided with duct
cover.
Use duct tape to make all joints secure and air tight. In some installations, it is easier to attach transition to plate
before attaching plate to hood.

diameter transition.
2. Slide the recirculating assembly
onto the top of the hood and
secure on the sides/rear using (6)

INSTALLING THE OPTIONAL DUCT COVER
1. Measure from top of the canopy to ceiling and subtract 1/8” (0.3 cm) for clearance.
2. Place the duct cover top inside the duct cover base and lower until desired height is found. (To eliminate
scratches, make a mark on the duct cover top for the desired lowering point by subtracting 18” (45.7 cm) from the
total height needed.)
3. Use the retaining nuts and bolts to fasten in place.
4. Slide the duct cover in place and fasten from inside canopy using the sheet metal screws provided.
5. Note: For installations with ceilings above 9’ (22.9 cm), use optional duct extensions. See product literature for
details
