IMPORTANT SAFETY INSTRUCTIONS

WARNING: TO REDUCE THE RISK OF FIRE, ELECTRIC

SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:

■ Use this unit only in the manner intended by the

manufacturer. If you have questions, contact the manufacturer.

■ Before servicing or cleaning the unit, switch power off at

service panel and lock the service disconnecting means to prevent power from being switched on accidentally. When the service disconnecting means cannot be locked, securely fasten a prominent warning device, such as a tag, to the service panel.

■ Installation work and electrical wiring must be done by

qualified person(s) in accordance with all applicable codes and standards, including fire-rated construction.

■ Do not operate any fan with a damaged cord or plug.

Discard fan or return to an authorized service facility for examination and/or repair.

■ Sufficient air is needed for proper combustion and

exhausting of gases through the flue (chimney) of fuel burning equipment to prevent backdrafting. 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 wall or ceiling; do not damage

electrical wiring and other utilities.

■ Ducted fans must always be vented outdoors. CAUTION: For general ventilating use only. Do not use

to exhaust hazardous or explosive materials and vapors.

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, attics or into crawl spaces, or garages.

WARNING: TO REDUCE THE RISK OF FIRE, USE ONLY

METAL DUCTWORK.

WARNING: TO REDUCE THE RISK OF A RANGE TOP

GREASE FIRE:

■ Never leave surface units unattended at high settings.

Boilovers cause smoking and greasy spillovers that may ignite. Heat oils slowly on low or medium settings.

■ Always turn hood ON when cooking at high heat or when

flambeing food (i.e. Crepes Suzette, Cherries Jubilee, Peppercorn Beef Flambé).

■ Clean ventilating 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 TO

PERSONS IN THE EVENT OF A RANGE TOP GREASE FIRE, OBSERVE 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 DEPARTMENT.

■ 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

already 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.

Venting Requirements

■ Vent system must terminate to the outdoors.

■ Do not terminate the vent system in an attic or other enclosed

area.

■ Do not use 4" (10.2 cm) laundry-type wall caps.

■ Use metal vent only. Rigid metal vent is recommended.

Plastic or metal foil vent is not recommended.

■ The length of vent system and number of elbows should be

kept to a minimum to provide efficient performance.

For the most efficient and quiet operation:

■ Use no more than three 90° elbows.

■ Make sure there is a minimum of 24" (61.0 cm) of straight

vent between the elbows if more than 1 elbow is used.

■ Do not install 2 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 wall or roof opening around the

cap.

■ The size of the vent should be uniform.

Cold weather installations

An additional back draft damper should be installed to minimize backward cold air flow and 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 locale to locale. Consult your HVAC professional for specific requirements in your area.

Venting Methods

Calculating Vent System Length

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

Vent Piece Equivalent Length

45° elbow 2.5 ft

(0.8 m)

90° elbow 5.0 ft

(1.5 m)

The maximum equivalent vent lengths are: 10" (25.4 cm) round vents - 60 ft (18.3 m)

Example vent system

90 elbow

2 ft

(0.6 m)

6 ft (1.8 m)

The following example falls within the maximum recommended vent length.

1 - 90° elbow = 5.0 ft (1.5 m) 1 - wall cap = 0.0 ft (0.0 m) 8 ft (2.4 m) straight = 8.0 ft (2.4 m)

Length of system = 13.0 ft (3.9 m)

Wall cap

A 10" (25.4 cm) round vent system is needed for installation (not included). The hood exhaust opening is 10" (25.4 cm) round.

NOTE: Flexible vent is not recommended. Flexible vent creates back pressure and air turbulence that greatly reduce performance.

Vent system can terminate either through the roof or wall.
