PLANNING DUCTWORK INSTALLATION

(This section for 40000 and 42000 hoods only. 41000 hoods skip this section and go on to “Prepare the Hood”.)
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. A – F below.

• FIG. A. 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 backdrafts. 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. B.
• In more complex ducting situations, a 3-1/4” x 10” rectangular ducting range hood (40000 hood) can be converted to a round duct by means of a transition.
• FIG. C. Straight up through the roof using 7” round duct (for single story installations – 42000 & 42000D hood only).
• FIG. D. Ducting straight up through the roof using 3-1/4” x 10” rectangular duct (for single story installations – 40000 hood only).
• FIG. E. 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. F. Straight up through the roof using 6” round duct (for single-story installations).

PREPARE THE HOOD

1. Unpack hood and check contents. You should receive:
   • 1 – Aluminum Filter (40000 and 42000 & 42000D hoods only)
   • 1 – 3-1/4” x 10” Damper/Duct Connector (mounted inside of hood for shipping only) (40000 hood only)
   • 1 – Ductfree Microtek® System I Filter (41000 hood only)
   • 1 – 7” Round Damper (42000D hoods only.)
2. Remove wiring box cover. Under cover find: 1 – Plastic Bag containing loose mounting hardware
3. Remove top or rear electrical knockout. (FIG. 2)
4. (40000 hood ONLY) Remove duct knockout. Insert screwdriver under edge of knockout, break tabs, and peel knockout back with pliers. (FIG. 3)
5. (40000 hood ONLY) Install damper/duct connector over opening made in STEP 4. Use #8B sheet metal screws provided. (FIG. 3)
   (42000 hood ONLY) Install Model 87 round damper (purchase separately) over openingin top of hood.
   (42000D hood ONLY – Install 7” round damper (included) over opening on top of hood.

PREPARE THE INSTALLATION LOCATION

Omit STEP 1 if hood will be installed under cabinets with flush bottom.

1. (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 deeper than 1” use thicker strips. Attach strips with 1-1/4” wood screws, 3” from each end of strip. See FIG. 4.

2. Measure and mark the following (FIGS. 5A & 5B):

   • Electrical wiring opening in wall or cabinet.
   • Duct opening in wall or cabinet (40000, 42000 & 42000D hoods ONLY). WARNING
     WHEN CUTTING OR DRILLING INTO WALL OR CABINET, BE CAREFUL NOT TO CUT EXISTING ELECTRICAL WIRING.

3. Use 1-1/4” bit to drill opening for electric wiring.

4. Cut out duct opening in wall or cabinet with saber saw or keyhole saw.

5. Center hood in installation opening and trace keyhole slots onto wood filler strips on cabinet bottom.

6. Screw four #10 x 7/8 wood screws into exact center of narrow end of traced keyhole slots. Allow 3/8” of screws to project, so that hood can be fitted into place later.

INSTALL THE DUCTWORK

(This section for 40000 and 42000 hoods only. 41000 hoods skip this section and go on to “Install Range Hood”.)

NOTE
These instructions will follow plans made on Page 2. Start at the exterior and run ductwork back to the range hood.
For best possible performance, use the shortest possible duct run and a minimum number of elbows. Do not vent a range hood into an attic space. A buildup of grease in the attic could become a fire hazard.
Use only metal ductwork. DO NOT USE PLASTIC DUCT. Assemble duct run securely so that in case of a grease fire on the range, the fire will be contained inside metal ductwork.

Tape all duct connections.

1. Follow appropriate directions below for type of duct run you install.
   • Wall Cap Discharge; (FIG. 7) Use saber saw or keyhole saw to cut hole slightly larger than duct size used so that duct will line up easily with damper/duct conector on hood. Install casing strips if cap will be installed on siding. Attach required amount of duct to wall cap and run duct back to hood. Fasten cap to wall and caulk well.
   • Roof Cap Discharge; (FIG. 8) Cut a hole in roof slightly larger than duct size being used. Run ductwork down to hood location. Leave 3/4” of duct projecting above roof surface on high side.
     Trim duct parallel to roof pitch and seal all around duct with roof cement .
     Carefully trim shingles and slide back of roof sheet under shingles. Nail roof sheet to roof under shingles at top two corners and two sides. Nail sheet directly to roof in four places at bottom.
     Using roof cement, seal all nail heads and shingles which were cut or lifted. Do not seal bottom edge of roof sheet.

INSTALL RANGE HOOD

WARNING
TURN OFF THE PROPER CIRCUIT AT THE SERVICE ENTRANCE BEFORE WIRING THIS RANGE HOOD.

1. Run electric wiring through hole drilled in wall or cabinet. Split wiring for 6” and install proper connector for type of wire used. (FIG. 9)

2. Position hood so that:

   • Wiring is routed through knockout opening (FIG. 10) (MX Series Only: Use grommet supplied in parts bag.)
   • Large part of keyhole slots fit over hood mounting screws. (FIG. 10) c.) Damper/duct connector slides into duct work. (40000, 42000 and 42000D hoods only)

CLEANING

Clean your hood with a mild detergent suitable for painted surfaces. DO NOT USE ABRASIVE CLOTH, STEEL WOOL PADS OR SCOURING POWDERS.
Fan assembly may be vacuumed. Fan assembly is permanently lubricated, and never needs oiling. If the product is making excessive or unusual noises, replace the motor or blower assembly.

HOW TO AVOID A COMMON RANGE-TOP GREASE FIRE

• Your range hood provides a protective barrier between the cooking surface and the cabinets.
• Keep fan, filters and grease laden surfaces CLEAN according to instructions.
• Always turn hood ON when cooking at high heat to keep the cooking area and the hood cooler.
• Use high heat settings only when necessary.
• Never leave cooking surface unattended. Boil-over causes smoking and greasy spillovers that may ignite.
• Always use adequate-sized utensils.
• If preparing flaming foods, such as Cherries Jubilee, always turn hood ON to HIGH to prevent a high heat situation which can cause damage or fire.

HOW TO EXTINGUISH A COMMON RANGE-TOP GREASE FIRE

• Never pick up a flaming pan. If dropped, flames can spread quickly.
• DO NOT USE WATER! A violent steam explosion may result. Wet dishcloths or towels are also dangerous.
• Smother flames with a close fitting lid, cookie sheet or metal tray.
• Flaming grease can also be extinguished with baking soda or a multi-purpose dry chemical extinguisher.
• Turn off surface units – if you can do so without getting burned.
