PLANNING DUCTWORK INSTALLATION

Begin planning ductwork by deciding where the duct will run between the range hood and the outside. For best performance, use the shortest possible duct run and a minimum number of elbows. There are several choices shown - FIGS. 1A - 1F.

If needed, a 3¼" x 10" rectangular ducting range hood can be converted to a round duct by means of a transition.
FIG. 1A. Ducting directly through the wall (for range hoods mounted on an exterior wall). Shown are two ways to duct through an outside wall. If a wall cap is used directly off the back of the hood, special care must be taken to make sure that the damper in the damper/duct connector on the hood and damper in the wall cap do not interfere with each other when the hood is operating. This could result in either inadequate air delivery or back drafts. If this condition does exist, remove the hood damper flap. Sometimes when using a wall cap it is easier to duct vertically and then use an elbow as shown in FIG. 1B.
FIG. 1C. Ducting straight up through the roof using 3¼" x 10" rectangular duct. (For single story installations.)
FIG. 1D. Ducting between the ceiling joists (for multi-story installations) or through the soffit space above the cabinets (where the soffit connects to an outside wall).
FIG. 1E. Straight up through the roof using 3¼" x 10" to 6" round duct transition and 6" round duct (for single-story installations).
FIG. 1F. Straight up through the roof using 7" round duct (for single-story installations).

PREPARING THE RANGE HOOD

1. Unpack hood and check contents. You should have:
   1 - Aluminum filter
   1 - 3¼" x 10" Damper/duct connector
   (mounted inside of hood for shipping only) (save the screws)
2. Remove wiring box cover. Under cover find the parts bag containing loose hardware.

For non-ducted installation only

3. For non-ducted installation, remove the grille cover plate retaining screw from inside the hood, then pull the grille cover plate out of the hood and discard.
   NOTE
   The grille on front of hood must be open and visible for hood to operate in non-ducted mode.
4. Remove either top or rear electrical knockout depending upon whether wiring will enter hood from wall or cabinet.
   

DUCTED INSTALLATION ONLY
NOTE
The grille cover plate must NOT be removed to function in ducted mode.

5. Remove appropriate duct knockout on hood by inserting screwdriver into edge of knockout and breaking tabs holding knockout to hood. Peel knockout back with pliers.
   
6. For 3¼" x 10" ducting only: Fit damper/duct connector over opening and secure in place using screws previously removed in PREPARING THE HOOD section
   
   Hinge pins and damper/duct connector should be toward top of hood for ducting through wall or toward back of hood for ducting through cabinet above hood. Seal joint between damper/duct connector and hood with duct tape.
7. 7" round ducted discharge only: Install, between 2 duct sections, a 7" round damper (purchase separately). Damper flap must open freely in direction of air flow (away from range hood).

PREPARING THE INSTALLATION LOCATION

NOTE
MOUNT HOOD SO THAT BOTTOM OF HOOD IS 20"-25" ABOVE COOKING SURFACE.
OMIT STEP 8 if range hood will be installed under cabinets with flush bottom.

8. (For installation on recessed bottom cabinets only.) Attach a wood filler strip at each side of recessed area under cabinet. (Use two 1" x 2" strips cut to length.) If recess is more than 1" use thicker strips. Attach strips with 1¼" screws about 3" from each end.
   
9. Measure and mark the following (FIGS. 7 & 8):
   
   1. Electrical line opening
   2. Duct opening
10. Drill four pilot holes in corners of marked duct opening as shown and cut opening with saber saw or keyhole saw.
11. Use 1¼" drill bit to drill opening for electrical connection in wall or cabinet.
12. Hold hood up against cabinet bottom and trace keyhole slots onto cabinet bottom or filler strips.
13. Screw the four supplied 7/8" wood screws for mounting the hood into the exact center of the narrow end of the keyhole slots marked underneath the cabinet. Allow 3/8" of the screws to project, so the hood can be fitted into place.

INSTALLING THE DUCTWORK

NOTE
START AT THE EXTERIOR AND RUN THE DUCT BACK TO THE RANGE HOOD.
FOR BEST PERFORMANCE OF YOUR RANGE HOOD, USE THE SHORTEST POSSIBLE DUCT RUN AND A MINIMUM NUMBER OF ELBOWS.
NEVER VENT A RANGE HOOD INTO AN ATTIC SPACE BECAUSE A BUILDUP OF GREASE WILL BECOME A FIRE HAZARD.
USE ONLY METAL DUCTWORK (DO NOT USE PLASTIC DUCT). ASSEMBLE SECURELY SO THAT IN CASE OF A GREASE FIRE ON THE RANGE, THE FIRE WILL BE CONTAINED INSIDE METAL DUCT WORK.
IT IS A GOOD PRACTICE TO TAPE WITH METAL DUCT TAPE ALL DUCT CONNECTIONS, MAKING THEM BOTH SECURE AND AIR TIGHT.

14. Follow appropriate directions below for type of ductwork you are installing:
    WALL CAP
    
    Use a saber saw to cut a hole slightly larger than duct so duct will line up easily with hood. Install casing strips on outside walls finished in siding. Assemble the duct work and tape all joints. Run duct work back to hood. Fasten wall cap to last section of duct and nail or screw cap to wall. Seal all around flange on wall cap with caulking compound for exterior use. Make sure that enough duct runs into the room so that the duct will overlap the damper/duct connector by 3/4" when the hood is installed.
    ROOF CAP
    Cut hole in roof slightly larger than duct so duct will line up easily with hood. Trim shingles around hole so that they will fit snugly around hood of cap when cap is installed. Assemble the ductwork and tape all joints. Run the ductwork down to hood. Trim duct parallel to roof pitch, leaving 3/4" of duct projecting above roof. Seal all around duct with roof cement. Install roof cap, inserting back edge of cap under shingles. Seal around cap with roof cement and seal all nail heads and shingles which were cut or lifted.
    Make sure that enough duct runs into the room so that the duct will overlap the damper/duct connector by 3/4" when the hood is put into place.

INSTALLING THE RANGE HOOD

15. Bring electrical cable through access hole drilled in wall or bottom of cabinet. Provide 6" wire leads and install proper connector for type of cable being used. Remove lock nut from connector and let prepared cable project through cabinet or wall opening so it is ready for installation into range hood.
    
16. Position hood in place so that:
    1. Electrical line is routed through appropriate knockout opening. This step will have to be accomplished while positioning hood.
       
    2. Large part of keyhole mounting slots on hood fit onto hood mounting screws projecting from bottom of cabinet. (FIG. 11)
    3. Damper/duct connector (if present) slides into duct work in wall or cabinet.
17. Tighten the four hood mounting screws securely.
18. Install locknut on electrical connector and tighten securely.
19. Make electrical connection using wire nuts to connect WHITE wires to WHITE, BLACK wires to BLACK, and GREEN or bare wire to GREEN ground screw provided.
    
20. Replace wiring box cover and screw, taking care not to pinch wires.
    NOTE
    For non-ducted installations only: Remove the aluminum filter from the hood. Attach the non-ducted filter (part number S97021380, purchase separately) on the back of aluminum filter (side without pull tab), using 4 provided clips (FIG. 13). Reinstall the aluminum filter.
    

USE AND CARE

CONTROL KNOBS
Right knob controls light and left knob controls blower.
Light:
Rotate light knob CLOCKWISE to turn ON the light. Rotate knob COUNTERCLOCKWISE to turn light OFF.
Blower:
Rotate blower knob CLOCKWISE to turn blower ON to LOW speed. Further CLOCKWISE rotation sets blower on HIGH speed. Rotate knob fully COUNTERCLOCKWISE (past LOW speed) to turn fan OFF.

CLEANING
Finish Keep your range hood clean using a mild detergent suitable for painted surfaces.
The aluminum filter should be cleaned frequently. Use a warm dishwashing detergent solution.
Clean all-metal filter using a non-phosphate detergent. Discoloration of the filter may occur if using phosphate detergents, or as a result of local water conditions - but this will not affect filter performance. This discoloration is not covered by the warranty. To minimize or prevent discoloration, hand wash filter using a mild detergent.

FILTER REMOVAL
Remove filter by pulling on its plastic tab.

LIGHT BULB REPLACEMENT
Light bulb (not supplied with hood) should be HALOGEN OR LED, but always GU10 base. Align the bulb leads with the small indentations located on the border of the lamp location on hood (see inset in FIG. 14), then install the bulb by placing the bulb leads into their grooves in the socket.

NOTE: Do not fold the plate (grey part in FIG. 14) located in the light bulb housing. Gently push upwards and turn clockwise until secured.
Halogen bulb: Shielded halogen bulb, GU10 base, 50 watts maximum.

Do not touch lamps during or soon after operation. Burns may occur. In order to prevent the risk of personal injury, only install shielded halogen lamps. Also, never install a cool beam, a dichroic lamp, a lamp not suitable for use in recessed luminaires or identified for use in enclosed fixtures.
LED bulb: 7 watts maximum, GU10 base.

7. Do not use this unit with any additional solid-state speed control device.
8. To reduce the risk of fire, use only metal ductwork.
9. This unit must be grounded.
10. When applicable local regulations comprise more restrictive installation and/or certification requirements, the aforementioned requirements prevail on those of this document and the installer agrees to conform to these at his own expense.

TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:

1. 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.
2. Always turn range hood ON when cooking at high heat or when flambeing food (i.e.: Crêpes Suzette, Cherries Jubilee, Peppercorn Beef Flambé).
3. Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan, filters or in exhaust ducts.
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 — You may be burned.
3. DO NOT USE WATER, including wet dishcloths or towels — This could cause a violent steam explosion.
4. Use an extinguisher ONLY if:
   1. You own a Class ABC extinguisher and you know how to operate it.
   2. The fire is small and contained in the area where it started.
   3. The fire department has been called.
   4. You can fight the fire with your back to an exit.

* Based on "Kitchen Fire Safety Tips" published by NFPA.

1. For indoor use only.
2. For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.
3. To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray, construction dust, etc. off power unit.
4. 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.
5. For best capture of cooking impurities, the bottom of the hood should be at a minimum of 20" and at a maximum of 25" above the cooking surface.
6. To reduce the risk of fire and to properly exhaust air, be sure to duct air outside — Donot exhaust air into spaces within walls or ceiling or into attics, crawl space or garage.
7. When installing, servicing or cleaning the unit, it is recommended to wear safety glasses and gloves.
