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. Ducted fans must always be vented to the outdoors.

7. Do not use this unit with an additional speed control device.

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

8. 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.

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

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

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

12. 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.

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 system can be easily installed
following these basic steps:

Cut out the countertop

•
opening.

Mount the unit in the

•
cabinet.

Install exterior blower

•
Connect the ductwork

•
and electrical.

Install the cooktop.

PLANNING - (continued)

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 2830 will fit in most 30" wide cabinets and the Model
2836 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.

3-1/4" x 10"
DISCHARGE

1. This downdraft blower system is most efficient when used with
10" round ductwork. Use a combination of elbows and transi­tions (shown below), closest to the downdraft, in order to get
from 3¼" x 10" to 10" round as soon as possible.

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.

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.

3. The system will operate most efficiently when the ductwork
does not exceed 40 feet of equivalent duct. The illustrations,
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 and exterior blower system normally draws 6
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 2830 is being
installed in a 30" wide cabinet or the Model 2836 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.

CUT COUNTERTOP OPENING

INSTALL DUCTWORK

1. Lay out and cut the cooktop cut-out far enough FORWARD so
downdraft will fit behind it.

2. Set cooktop in place and slide it as far forward as possible.
Center and square it with edges of countertop.

3. Place the plastic template against the back flange of the
cooktop and center it. Trace around template to mark the
downdraft opening.

4. Remove cooktop from countertop.

5. Cut downdraft opening. Be careful not to chip edges of
countertop.

ASSEMBLY

1. Cut hole in cabinet as well as holes in wall or floor as
necessary.

2. Mount the exterior blower and work back towards the cabinet,
attaching all ductwork, elbows and transitions as previously
planned. Tape all ductwork connections to make them secure
and air tight.

3. Connect ductwork (and transition, if required) to downdraft. If
necessary, LOOSEN nuts and screws that hold the blower in
place, and slide outlet assembly left or right to meet ductwork.
Re-tighten screws and nuts.

ELBOW

1. Set downdraft into opening. Extend leveling brackets to floor
of cabinet so downdraft sits straight. (Note: Leveling brackets
can be removed and re-attached in other positions. Bottom
flange may have to face inward in tight cabinet installations.)

2. Secure the downdraft to the countertop as follows: Hold the
downdraft against the back of countertop cut-out and tighten­ing the 2 mounting screws (one on each end of unit) on
underside of countertop. Use a wood shim between screw and
underside of granite countertops.

3. Screw leveling brackets to bottom of cabinet. Tighten screws
holding leveling bracket to unit on each side.

INSTALL ELECTRICAL WIRING

1. Mount a standard wiring box, with 3-pronged grounded recep­tacle, inside the kitchen cabinet. Make sure the unit's power
cord can easily reach it.

2. Run appropriate power cable into cabinet and connect it to
electrical box and receptacle.

3. Exterior blower may not exceed 6.0 Amp rating.

4. Run 2-wire plus ground power cable from the remote blower
to wiring box on downdraft. Remove wire box cover and attach
cable using proper certified or recognized connector. Use
recognized wire connectors to connect wires. Make sure wires
cannot come loose from connectors after assembly.

5. Connect downdraft wiring to power cable from remote blower.
Wire black to black, white to white and green to green or bare
wire.

6. Replace wiring box cover.
