INTENDED FOR DOMESTIC COOKING ONLY

IMPORTANT SAFETY INSTRUCTIONS

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

1. Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer at the address or telephone number listed in the warranty.

2. Before servicing or cleaning unit, switch power off at service panel and lock service panel 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.

3. Installation work and electrical wiring must be done by a qualified person(s) in accordance with all applicable codes and standards, including fire-rated construction codes and standards.

4. 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), and the American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities.

5. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.

6. Ducted fans must always be vented to the outdoors.

7. Use with approved cord-connection kit only.

8. To reduce the risk of fire, use only metal ductwork.

TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:

1. Never leave cause smoking and greasy spillovers that may ignite. Heat oils slowly on low or medium settings.

2. Always turn hood ON when cooking at high heat or when cooking flaming foods.

3. Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan or filter.

4. Use proper pan size. Always use cookware appropriate for the size of the surface element.

TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT OF A RANGE TOP GREASE FIRE, OBSERVE THE FOLLOWING*:

1. 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.

2. NEVER PICK UP A FLAMING PAN - Yo u may be burned.

3. DO NOT USE WATER, including wet dishcloths or towels - a violent steam explosion will result.

4. Use an extinguisher ONLY if:

A . You know you have a Class ABC extinguisher, and you already

know how to operate it. B. The fire is small and contained in the area where it started. C. The fire department is being called. D. Yo u can fight the fire with your back to an exit. * Based on “Kitchen Firesafety Tips” published by NFPA.

IMPORTANT SAFETY INSTRUCTIONS

1. F or indoor use only.

2. For general ventilating use only. Do not use to exhaust hazardous

or explosive materials and vapors.

3. To reduce the risk of fire or electrical shock, this range hood should not be used with an additional speed control device.

4. To reduce the risk of shock, disconnect power before servicing.

5. To reduce the risk of fire and to properly exhaust air, be sure to duct air outside.

6. Your hood motor has a thermal overload which will automatically shut off the motor if it becomes overheated. The motor will restart when it cools down. If the motor continues to shut off and restart, have the hood serviced.

PLAN THE INSTALLATION

Recommended mounting height is 18” to 24” from the bottom of the range hood to the top of the cooking surface.

The hood should be mounted to the bottom of a standard wall cabinet. If the hood must be mounted directly to a wall, secure the hood to wall studs.

All wiring must comply with local codes and the unit must be properly grounded. The hood is connected to a 110-120vAC lighting circuit (15 amp) in the circuit breaker or fuse box.

This range hood is “Convertible” – it may be installed as a ducted or as a

non-ducted unit.

IF THE RANGE HOOD IS TO BE NON-DUCTED:

Purchase non-ducted (duct-free) charcoal filter Model BPQTF.

IF THE RANGE HOOD IS TO BE DUCTED:

Ductwork can be installed vertically or horizontally. Duct runs should be as short as possible. Avoid the use of elbows. Use duct tape at all joints. Do not use duct smaller than the discharge on the hood. For 7” round ductwork installation, use 7” round damper, Model

BP87 (purchased separately).

PREPARATION

1. Use the dimensional drawings (Refer to FIGURES 1 - 3) to

lay out the range hood’s mounting holes, wiring access and ductwork by marking the cabinet bottom and drywall where applicable.

2. Make cutouts for wiring and ductwork.

3. If the hood is to be ducted, install the ductwork so that is flush to the range hood’s mounting surface.

Refer to FIGURE 1 if the range hood is to be installed with a horizontal discharge.

Refer to FIGURE 2 and FIGURE 3 if the range hood is to be installed with a vertical discharge.

4. Run two-conductor wire (with ground) from a power source to the hood location. Bring approximately 12” of wiring through wiring hole in cabinet.

5. Drill four 3/32” diameter pilot holes at points where mounting holes are marked in cabinet bottom.

6. Insert four (4) mounting screws, leaving approximately ¼” of thread exposed.

7. Remove and retain the mounting screws securing the 3¼” x 10” and 7” duct transitions to the hood. Install the appropriate duct transition as described in the installation section.

INSTALLATION

1. Remove the necessary duct opening and wiring knockout from the range hood.

If the range hood is to be installed as a non-ducted unit,

remove the wiring knockout only. If the range hood is to be installed as a ducted unit, a baffle

plate is provided to close off the non-ducted vent. Install baffle plate (Refer to FIGURE 4) by sliding into place behind grille. Use locator bumps to orient in

. For 7” round discharge installation, refer to FIGURE 5. Se-

cure 7” adapter (included) to top of hood using screws provided. Install 7” round damper (Model BP87, purchased separately).

For 3¼” x 10” vertical discharge installation, refer to FIGURE

6. Secure 3¼” x 10” transition (if used) to top of hood. For 3¼” x 10” horizontal discharge installation, refer to FIG-

URE 7. If using supplied 3¼” x 10” duct transition, secure it to

the range hood. Ensure that the damper flap operates fully and freely. If it does not, remove the damper flap or make necessary modifications to the installation to insure full and free operation of the damper flap.

3. Feed the wiring through the access hold and into the electrical box.

4. Align hood’s keyhole mounting slots over the four (4) partially installed screws.

5. Making sure the duct positions over the hood’s duct transition, push the hood against the rear wall. Secure hood by tightening screws.

6. Using a long blade screwdriver, reach into the discharge opening and make sure the damper flap operates freely (vertical discharge only).

HOOD WIRING

All wiring connections must comply with local codes and the unit must be properly grounded.

1. Make sure box connector is secure.

2. Refer to FIGURE 8. Make wiring connections.

3. Replace electrical box cover and secure with screw.

LAMP INSTALLING OR REPLACEMENT

1. Depress sides of light diffuser until tabs of diffuser disengage from slots in hood. Remove diffuser.

2. Install (2) 40 watt maximum, Type A-15 appliance bulbs.

3. Replace difuser in hood by depressing sides and engaging tabs in slots in hood.

FILTER INSTALLATION AND REPLACEMENT

1. Fo r ducted operation, install the aluminum mesh filter. For nonduct operation, install the non-ducted filter (Model BPQTF, sold separately).

2. Refer to FIGURE 9. The filter slides into channels at the back of the hood, on either side of the fan compartment, and snaps under the spring clips near the front of the fan compartment.

MAINTENANCE

FILTERS IMPORTANT: The aluminum filter should be removed once monthly

and washed in hot detergent water. Rinse in clear, warm water and shake off excess moisture before replacing. The filter may also be cleaned in your dishwasher.

IN A NON-DUCTED INSTALLATION: Replace filter every 3-6 months as needed.

CLEANING

The hood should be wiped off occasionally both inside and outside using warm water, mild dish detergent and a soft cloth. Never use scouring powders, steel wool pads or any other which will destroy the hood’s finish.
