IMPORTANT SAFETY INSTRUCTIONS

WARNING: TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, READ THE FOLLOWING:

➢ Use this unit only in the manner intended by the manufacturer. If you have questions, please contact the

manufacturer.

➢ Before servicing or cleaning the unit, switch the power off and turn power off at the electrical panel and lock

the service panel. This will prevent the power from accidentally turning on. If the service panel does not lock,
secure a warning label, such as a tag, to the service panel.

➢ Installation work and electrical wiring must be done by a qualified professional(s) in accordance with all

applicable codes, standards, and fire-rated constructions.

➢ Do not operate any fans with a damaged cord or plug. Discard the fan or return to an authorized service

facility for further examination and/or repair.

➢ To prevent back draft, sufficient air is needed for proper combustion. Gas from the fuel burning equipment

needs to exhaust through the flue (chimney). Follow the heating equipment manufacturer’s guideline and

safety standards such as 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 properly 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 unattended 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 range hood ON when cooking at high heat or when cooking food with high flames.
➢ Clean ventilation fans frequently. Grease should not be allowed to accumulate on fan or filter.
➢ Use proper pan size. Always use cookware appropriate 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-fitting lid, cookie sheet or metal tray, then turn off the burner. BE CAREFUL TO

PREVENT BURNS. If the flames do not go out immediately. EVACUATE AND CALL THE FIRE DEPARMENT.

➢ NEVER PICK UP A FLAMING PAN – you may be burned.
➢ DO NOT USE WATER, including wet dishcloths or towels – a violent steam explosion will result.
➢ Use an extinguisher ONLY if:

-You know you have a class ABC extinguisher, and you know how to operate it.

-The fire is small and contained in the area where it started.

-The fire department is being called.

-You can fight the fire with your back to an exit.

Based on “Kitchen Fire Safety Tips” published by NFPA
WARNING: To reduce the risk of fire or electrical shock, do not use this fan with any solid-state speed control
device.

LOCATION REQUIREMENTS

IMPORTANT: Observe all governing codes and ordinances. Have a qualified technician install the range hood. It is
the installer's responsibility to comply with installation clearances specified 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.
Cabinet opening dimensions that are shown must be used. Given dimensions provide minimum clearance.

ELECTRICAL REQUIREMENTS

Observe all governing codes and ordinances. Ensure that the electrical installation is adequate and in conformance
with the National Electrical Codes, ANSI/NFPA 70 (latest edition), or CSA Standards C22.1-94, Canadian Electrical
Code, Part 1 and C22.2 No. 0-M91 (latest edition), all local codes, and ordinances. If codes permit and a separate
ground wire is used, it is recommended that a qualified electrician determine that the ground path is adequate.
A copy of the above code standards can be obtained from:

➢ A 120 volt, 60 Hz., AC only, 15-amp, fused electrical circuit is required.
➢ If the house has aluminum wiring, follow the procedure below:

o Connect a section of solid copper wire to the pigtail leads.
o Connect the aluminum wiring to the copper wire using special connectors and/or tools designed

and UL listed for joining copper to aluminum. Follow the manufacturer’s recommended procedure

for the electrical connector. Aluminum/copper connection must conform to local codes and
industry accepted wiring practice.

➢ Wire sizes and connections must conform to the rating of the appliance as specified on the model/serial

rating plate. The model/serial plate is located behind the filter on the rear wall of the range hood.

➢ Wire sizes must conform to the requirements of the National Electrical Code, ANSI/NFPA 70 (latest edition),

or CSA Standards C22. 1-94, Canadian Electrical Code, Part 1 and C22.2 No. 0-M91 (latest edition) and all

local codes and ordinances.

VENTILATION REQUIREMENTS

General requirements

➢ Range hoods must be ventilated to the outdoors, except for non-vented (recirculating) installations.
➢ Do not ventilate the range hood into an attic or other enclosed areas.
➢ Do not use 4” (10.2 cm) laundry-type wall caps.
➢ The length of the range hood and the number of elbows should be kept to a minimum to provide maximum

performance.

For the most efficient and quiet operation

➢ Use no more than three 90-degree elbow.
➢ 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 and tape 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.

Cold Weather Installations

An additional back draft damper should be installed to minimize backward cold air flow. 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.

Makeup Air

Local building codes may require the use of makeup air systems, when using ventilation systems greater than
specified CFM of air movement. The specified CFM varies from state to state. Consult your HVAC professional for
specific requirements in your area.

For Non-Vented (recirculating) Installations

If it is not possible to vent cooking fumes and vapors to the outside, certain hoods can be used in the non-vented
(recirculating) version, fitting a carbon filter at the motor. Fumes and vapors are the recycled through the top
grille. DO NOT block the chimney holes.

Calculating Vent System Length

To calculate the length of the system you need, add the equivalent feet (meters) for all vent pieces used in the
system.

INSTALLATION DIMENSION RECOMMENDATIONS

For Island range hoods:

A. Countertop Height.
B. Hood height from ceiling to bottom of the range hood filter surface: D-A-C=B.
C. 24” minimum from cooking surface up to 36” maximum for Electric/Induction range tops. 27” minimum

from cooking surface up to 36” maximum for Gas range tops.

D. Floor to ceiling height.

Prior to installation

➢ Unpack range hood and ensure all listed parts are in the box.
➢ It is recommended for the vent system to be installed before hood is installed.
➢ Before making cutouts, make sure there is proper clearance within the ceiling or walls for the exhaust

vent.

➢ Determine which venting method to use: roof or wall.
➢ It is recommended that a professional installer perform the range hood installation.

Installing the range hood

This installation is for mounting the product to a ceiling. Ensure your ceiling has the proper support to
hold the range hood weight. These instructions are general guidelines, please consult professional
installation specialist regarding the best type of mounting hardware and support system based on
your ceiling construction. All island range hoods must be installed and supported by studs and joists in
your ceiling. All homes constructions are different and installations will vary.

1. Begin installation by removing the filters (D) and removing any tape on the air flow flappers (C).

2. Remove protective film from range hood and ducting. When handling the ducting please wear protective

gloves to avoid sharp edges.

3. If your model has an electronic touch sensor control panel, remove the protective plastic film covering the

control panel.
