Your safety and the safety of
others are very important,
We have provided many important
safety messages in this manual
and on your appliance. Always
read and obey all safety
messages.
This is the safety alert
symbol.
This symbol alerts you to
potential hazards that can kill or
hurt you and others.
All safety messages will follow the
safety alert symbol and either the
word "DANGER" or "WARNING".
These words mean:
You can be killed or seriously
injured if you don't immediately
foltow instructions.
You can be killed or seriously
injured if you don't foltow
instructions.
All safety messages will tell you
what the potential hazard is, tell you
how to reduce the chance of injury,
and tell you what can happen if the
instructionsare not followed.
mmportant: Observe aH governing
codes and ordinances,
Proper installation is your
responsibility. Make sure you have
everything necessary for correct
installation. It is the responsibility
of the installer to comply with the
installation clearances specified on
the model/serial rating plate.The
model/serial rating plate is located
on the front of the downdraft vent
above the wiring box cover.
Mobile home installation
The installation of this range hood
must conform to the Manufactured
Home Construction Safety
Standards, Title 24 CFR, Part 328
(formerly the Federal Standard for
Mobile Home Construction and
Safety, Title 24, HUD, Part 289) or
when such standard is not
applicable, the Standard for
Manufactured Home Installation
1982 (Manufactured Home Sites,
Communities and Setups) ANSI
A225.1/NFPA 591A*, or latest
edition, or with local codes.
Check location where downdraft
vent will be installed.The location
should be away from strong draft
areas, such as windows, doors
and strong heating vents or fans.
Before making countertop cutout,
check that downdraft vent and
cooktop location will clear cabinet
walls, backsplash, and rear wall
studs inside cabinet.
ALL OPENINGS IN THE WALL OR
FLOOR WHERE RETRACTABLE
DOWNDRAFT VENT iS TO BE
INSTALLED MUST BE SEALED.
Electrical ground is required. See
"Electrical requirements;' page 3.
When installing downdraft vent,
the cabinet drawer will need to be
removed and the drawer front
installed permanently to cabinet.
Note: Downdraft vent is installed
directly behind the cooktop. Install
downdraft vent first.
Cabinet construction: Downdraft
vent is designed for use in a
cabinet with a depth of 24"
(61 cm). Some installations
require a countertop deeper than
25" (63.5 cmL See chart on page 5.
The maximum depth of the
overhead cabinet is 13" (33 cm).
Overhead cabinets installed at
either side of the downdraft vent
must be 18" (45.7 cm) above the
cooking surface.
See cooktop Installation
instructions before making any
cutouts and for the minimum
distance between the front edge
of the countertop and front edge
of cooktop.The minimum
horizontal distance between the
overhead cabinets is the same as
the width of the installed
downdraft vent.
When installing a 36" (91.4 cm)
retractable downdraft vent with
"Create-A-Cooktop" modules, the
optional support must be installed
on the front of the downdraft vent.
See installation steps for details.

iMPORTANT
Save installation instructions for
electrical inspector's use.
A 120-volt, 60-Hz, AC-only
electrical supply is required on a
separate 15-ampere circuit, fused
on both sides of the line. A time-
delay fuse or circuit breaker is
recommended.The fuse must be
sized per local codes in
accordance with the electrical
rating of the downdraft vent as
specified on the model/serial
rating plate located on the front
of the downdraft vent above the
wiring box cover.
THE DOWNDRAFT VENT
MUST BE CONNECTEDWITH
COPPER WIRE ONLY.

WARNING -- TO REDUCE THE
RISK OF FIRE, ELECTRIC
SHOCK, OR INJURY TO
PERSONS, OBSERVE THE
FOLLOWING:
Installation work and electrical
wiring must be done by qualified
person(s) in accordance with all
applicabb Codes and Standards,
including fire related construction.
Sufficient air is needed for proper
combustion and exhausting of
gases through the flue (chimney)
of fuel burning equipment to
prevent back drafting. 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
of Heating Refrigeration and Air
Conditioning Engineers
(ASHRAE), and the local code
authorities.
When cutting or drilling into wall
or ceiling, do not damage
electrical wiring and other hidden
utilities.
Ducted fans must always be
vented to the outdoors.
WARNING --To reduce the risk
of fire, use only metal ductwork.
This unit must be grounded.
This downdraft vent should
be connected directly to the fused
disconnect (or circuit breaker)
through flexible, armored or non-
metallic sheathed, copper cable.
Allow some slack in the cable so
the downdraft vent can be moved
if servicing is ever necessary.
E,, A U.L.- or C.S.A.qisted, 1/2"
(12.7 ram) conduit connector
must be provided at each end of
the power supply cable (at the
downdraft vent and at the
junction box).
A wiring diagram is located
on the downdraft vent base
above the wiring box cover.

Do not use plastic or metal foil
vent.
Vent work needed for installation
is not supplied.
Wall cap is Not provided with
interior-mounted motor.
Determine which venting method
to use. Vent system can extend
through either the wall or roof.
The length of vent system and
number of elbows should be kept
to a minimum to provide efficient
performance.
The size of the vent shouH be
uniform.
Do Not install two elbows
together.
Use duct tape to seaUaH joints in
the vent system.
Use caulking tape to seaUthe

For best performance, use no more
than three go° elbow's. If more than
one elbow, is used, make sure that
there is a minimum of 24" (61 cm) of
straight vent between any two
elbows. Do Not install two elbows
together. It is recommended that
you use round vent instead of
