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 in the warranty.

2. Before servicing or cleaning 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.

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. Do not use this range hood with an additional speed control device.

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

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

9. Do not install this product with the activating switch directly behind a burner or element. Minimum distance between the switch and the edge of the burner should be 4 inches.

10.Loose-fitting or hanging clothing should never be worn when operating this appliance. They may be ignited by burners/ elements on cooktop.

11. Children should not be left alone or unattended in the area where this appliance is in use.

12.When flaming foods, turn the blower OFF. An operating blower may spread the flames.

13. This unit must be grounded.

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 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

WARNING

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 immedi ately, 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

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

Based on “Kitchen Firesafety Tips” published by NFPA.

CAUTION

1. For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.

2. To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray, construction dust, etc. off power unit.

3. Clean filters and grease-laden surfaces frequently.

4. Do not repair or replace any part of this appliance unless specifically recommended in this manual. All other servicing should be done by a qualified technician.

5. Please read specification label on product for further information and requirements.

PLANNING

This downdraft blower system is designed to be used to exhaust airborne contaminants when cooking with a variety of gas or electric cooktops. It can be mounted in island, peninsula, or conventional wall locations.

This unit can be easily installed following these basic steps:

Cut out the countertop

Note: The high level of air flow of this appliance may affect the gas

flame on some types of gas cooktops. This is NORMAL and will cause no harm, but can be corrected by lowering the speed of the blower.

TAKE MEASUREMENTS

1. Refer to the cooktop installation instructions for dimensions of cooktop, countertop cut-out, and cabinet requirements. The Model 2730 will fit in most 30" wide cabinets and the Model 2736 will fit in most 36" wide cabinets. However, it is recommended that oversized cabinets be used for easier installation.

2. Cooktop depth can vary greatly from one to another. This may cause the fit of these two appliances to be rather tight.

PLAN THE DUCTWORK

RIGHT DISCHARGE

LEFT DISCHARGE

DOWN DISCHARGE (as shipped)

1. This downdraft blower system is designed for use with 3-1/4" x 10" ductwork (can be transitioned to 6" round). Three different discharge directions are available with side-to-side adjustment for accurate alignment of ductwork.

2. For best performance: Choose the ducting option which allows the shortest length of ductwork and a minimum number of elbows and transitions. Check location of floor joists, wall studs, electrical wiring or plumbing for possible interference. NOTE: The unit is shipped with the 3-1/4" x 10" discharge facing DOWN. See “CHANGING BLOWER DIRECTION” on page 3, if necessary.

6" ROUND ELBOW

3-1/4" X 10" TO 6" RD. TRANSITION

Pay special attention to the areas of potential interference highlighted above. A countertop with (A) a raised lip and/or (B) a backsplash may not allow enough flat countertop for a proper installation. Note that 2" of flat countertop is required behind cooktop and that 1-3/4" is necessary between the back edge of the cooktop and the inside of cabinet back.

EQUALS 8 FT. OF STRAIGHT DUCT

3. The system will operate most efficiently when the ductwork does not exceed 40 feet of equivalent duct. The chart, above, shows equivalent feet of elbows and transitions. The number of feet of straight duct plus the equivalent feet of transitions and/or elbows to be used should equal 40 feet or less.

NOTE: The equivalent feet of various roof and wall caps has been taken into consideration. Do not include them in this calculation.

PLAN THE WIRING

1. The downdraft blower system draws 4 AMPS and requires a 120 VAC, 60 Hz circuit.

2. The unit has a 2 ft. long power cord with a 3-pronged plug. Plan to provide a grounded outlet in a location which will allow the unit’s power cord to reach. (Note: If the Model 2730 is being installed in a 30" wide cabinet or the Model 2736 is being installed in a 36" wide cabinet, the outlet cannot be located on the back wall of cabinet.) Outlet may also be wall-mounted,

with access hole in cabinet.
