IMPORTANT SAFETY INSTRUCTIONS
WARNING: TO REDUCE THE RISK OF FIRE,
ELECTRIC SHOCK, OR INJURY TO PERSONS,
READ THE FOLLOWING:
Use this unit only un the manner intended by the
manufacturer. If you have questions, please contact the
manufacturer.
Before servicing or cleaning the unit, switch the power o
and lock the service panel. This will prevent the power for
accidentally turning on. If the service panel does not lock,
secure a warning label, such as tag, to the service panel.
Installation work and electrical wiring must be done by a
qualied proesional(s) in accordance with all applicable
codes, standars, and re-rated constructions.
Do not operate any fans with a damaged cord or plug.
Discard the fn or return it to an autorized service facility for
further examination and/or repair.
To prevent back draft, sucient air is needed for proper
combustion. Gas from fuel burning equipment needs to
exhaust through the ue (chimney). Follow the heating
equipment manufacturer´s guideline and safety standards
such a those published by the National Fire Protection
Association (NFPA), the American Society for Heating,
Refrigeration and Air Conditioning Engineers (ASHRAE),
and the local code authorities.
When cutting or drilling into walls or ceilings; be aware of
electrical wires, piping, and other utilities.
Ducted fans must always be vented outdoors.
CAUTION: For general ventilation use only. Do
not use to exhaust hazardous or explosive
materials and vapors.
CAUTION: To reduce the risk of fire and to
porperly exhaust air, be sure to duct air
outside. - DO NOT vent exhaust air into attics,
crawl spaces, garages, or within walls and
ceilings.
WARNING: TO REDUCE THE RISK OF A RANGE
TOP GREASE FIRE, READ THE FOLLOWING:
Never leave surface units unatended at high settings,
Boil-over can cause smoke and grease to spill over that
may ignite. Heat oils slowly on low or medium settings.
Always turn the hood ON when cooking at high heat or
when ambeing food (i.e. Crepes Suzette, Cherries Jubilee,
Peppercorn Beef Flambé).
Use proper pan size. Always use cookware appropiate for
the size of the surface element.
WARNING: TO REDUCE THE RISK OF INJURY. IN
THE EVENT OF A RANGE TOP GREASE FIRE,
READ THE FOLLOWING:
SMOTHER FLAMES with a close tting lid, cookie sheet, or
metal tray, then turn o the burner. BE CAREFUL TO
PREVENT BURNS. If the ames do not go out imemediately,
EVACUATE AND CALL THE FIRE DEPARTMENT.
NEVER PICK UP A FLAMING PAN - you may get burned
DO NOT USE WATER, including wet dishcloths or towels - a
violent steam explosion will result.
Use a re extinguisher ONLY if:
- You know you have a class ABC extinguisher, and you
already know how to operate it.
- The re is small and contained in the area where ir
started.
- The re department is being called.
- You can ght the re with your back to an exit.

Observe all governing codes and local ordinances. Have a qualied technician install the range hood. It is the installer´s
responsibility to comply with installation clearences specied on the model serial rating plate.
Canopy hood´s location should be away from strong draft areas, such as windows, doors, and strong heating vents.
Recommended heights are shown. Given dimensions provide minimum cleareance.
Body (Main Unit): 1 pc
Installation Manual: 1 pc
Metal Grease Filter: 1-4 pcs
Hardware: 1 set

Range hoods must be ventilated to the outdoors, except for non-vented (recirculating) installations.
Do not ventilate the range hood into an arric or other encloed areas.
Do not use 4” (10.2 cm) laundry-type wall caps.
The length of the range hood exhaust and the number of elbows should be kept to a minimum to provde maximum
performance.
Use no more than three 90° elbows.
Make sure there is a minimum of 24”(61 cm) of straight duct between the elbows if more than one elbow is used.
Do not install two elbows together.
Use clamps to seal all joints in the vent system.
The vent system must have a damper. If the roof or wall cap has a damper, do not use the damper supplied with the
range hood.
Use caulking to seal exterior walls or roof openings around the cap.
The size of the vents should be uniform
VENTILATION REQUIREMENTS
Local building codes may require the use of makeup air systems, when using ventilation systems greater than specied
CFM of air movements in your area.
MAKEUP AIR
An additional back draft damper should be installed to minimize backward cold air ow. A thermal break should be
installed to minimize conduction of outside temperatures as part of the vent system. The damper should be on the cold
air side of the thermal break. The break should be as close as possible to where the vent system enters the heated portion
of the house.
COLD WEATHER INSTALLATIONS
This canopy hood is factory set for through the roof wall. A 6” (15.2 cm) round vent system is needed for installation.
The hood exhaust opening is 6” (15.2 cm ) round. To vent through a wall, a 90° elbow is needed. If exhaust ducting with
a diameter of less than 5.91” (150 mm) or if at ducting is used, the noise level of the range hood will increase and
extraction will be less ecient.
VENTING METHOD
A 90° elbow may be installed immediately above the hood.

ATTENTION HOMEOWNER
These installation steps are meant to be a general guideline for mounting and installing your under cabinet range hood.
If you require assistance, please contact your local contractor.
Please exercise extreme caution when handling a range hood to prevent risk of injury and electric shock.
Building codes will vary. It is the buyer or contractor’s responsibility to know local county or state regulations before
installation of this range hood.
PREPARATIONS:
NOTE: To avoid damage to your hood, prevent debris from entering the vent opening
Decide the location of the venting pipe from the hood to the outside. Please see“Venting Method” section.
A straight, short vent will allow the hood to perform more eciently.
Try to avoid as many transitions, elbows, and long run as possible. This may reduce the performance of the hood.
IMPORTANT: Peel white or blue plastic protective lm o the hood.
Use HVAC foil tape / duct tape to seal joints between the pipe sections.
For installing under cabinets with a recessed bottom, attach 4-inch wide wood ller strips (not provided) on each side.
Refer to Figure 1.
Using references in measurements and diagrams provided, create an opening for electrical wires and hood exhaust
under the cabinet
CAUTION: If moving the cooking range is necessary to install the hood, rst turn o the power.
Always turn o the gas before moving a gas range.
Puncture the knockout holes (for mounting under the cabinet) on the hood as shown in Figure 2.
If necessary, attach two rubber panels with adhesive tape to the rear corners of the range hood.
This will help reduce vibrations and shaking when in operation.

Proceed if you would like to mount this range hood using the provided hood mounting bracket (If included).
1. Using references in the Location Requirements section, mark the leveling point of the hood. Position two mounting
screws on the wall, leaving 1/8” space away from the wall. Mounting the hood on wall studs is highly recommended.
2. Attach the hood mounting bracket to the back of the hood with four screws as shown in Figure 3.
3. Puncture the knockout wire access hole at the back of the hood and draw the electrical wires.
4. Align hood-mounting brackets to the screws on the wall and hook the hood into place as shown on the next page.
5. Tighten screws to secure hood to the wall.
CAUTION: Make certain the range hood is fully secured before releasing!

STEP 1 | METHOD A
Two people will be required to lift and install the main unit. We highly recommend professional help and an extra set of
hands.
Measure the distance between the stove top and the bottom of the range hood. A distance of 24” to 32” is
recommended.
There are two methods (A or B) to mount the range hood, choose the one that better ts your setup and model.
Proceed if you would like to mount this range hood without using the hood mounting bracket.
1. Using references in the Location Requirements section, center the hood beneath the cabinet and ush with the front
of the cabinet.
2. Draw the electrical wires through the cabinet access opening if not done so already.
3. From inside of the hood, place screws into the exact center of each knockout hole and secure to cabinet bottom. Finish
tightening all screws until secure. Be careful when using electrical screwdrivers, they may cause damage to the range
hood.
Skip Method B below and proceed to step 2.
CAUTION: Make certain the range hood is fully secured before releasing!
