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.
Ifyou 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

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 bythe National Fire Protection Association (NFPA),
and the American Society for Heating, Refrigeration and Air
Conditioning Engineers (ASHRAE), and the local code au-

thorities.

5. When cutting or drilling into walt 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.
Boitovers cause smoking and greasy spittovers 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

FOLLOWINGa:

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
atety, EVACUATE AND CALL THE FIRE DEPARTMENT.

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

3. DO NOT USE WATER, includingwet dishcloths or towels

- a violent steam explosion will result.

4. Use an extinguisher ONLY if:

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.

a 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 unbal-
anced 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

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 wilt fit in most 36" wide cabinets, However, it is recom-

mended that oversized cabinets beused 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.

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 DI-

RECTION" on page 3, if necessary.

Pay special attention to the areas of potential interference
highlighted above, A countertop with (A) a raised tip and/or (B) a

backsplash may not allow enough fiat 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,

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 wilt allow
the unit's power cord to reach. (Note: If the Model 2730 is
being installed in a30"wide cabinet or the Model 2736 is being

installed in a 36" wide cabinet, the outlet cannot be located on
the back walt of cabinet.) Outlet may also be wall-mounted,

CHANGING BLOWER DISCHARGE (Optional)

The blower is shipped with its discharge facing DOWN. Follow
these steps ONLY if:

• the position of the blower discharge needs to be moved
so ductwork does not interfere with floor joists, plumb

ing or wiring below.
it is necessary to rotate the blower discharge to the

RIGHT or LEFT.

Place the unit on its back on a table or work surface.
