WARNING
Electrical Shock Hazard
It is the customer’s responsibility to contact a
qualified electrical installer, to make sure that
the electrical installation is correct, and to
make sure the electrical installation follows the
National Electrical Code, ANSI/NFPA 70 —
latest edition*, and all local codes and
ordinances.
Take special care when cutting holes into a
wall. Electrical wires may be behind the wall
covering and could cause an electrical shock if
you touch them.
Disconnect the power to any electrical circuits
that could be affected by the installation of this
product.
Failure to do so could result in death or serious
injury.
Injury Hazard
To eliminate the risk of burns or fires, Do Not
install cabinets or store things above the
cooktop. If cabinets are already installed above
the cooktop, install a range hood to the
bottom of the cabinet to prevent reaching over
a heated cooking surface. The range hood
should stick out a minimum of 5 inches
(12.7 cm) from the front of the cabinets.
Reaching over a heated cooking surface could
result in a serious burn or other injury.
If cabinet has drawers, drawers will need to
be removed and drawer fronts installed on
front of cabinet.

Venting requirements
WARNING
!
Fire Hazard
The venting system MUST end outdoors.
Do Not end the ductwork in an attic, wall,
ceiling or other enclosed space.
Do Not use 4" laundry-type wall caps.
Do Not use plastic-type duct.
Do Not block the flow of ventilation air.
Failure to follow these instructions could result
in a fire.
Duct materials needed for installation is not
supplied.
Before making cutouts, make sure there is proper
clearance within the wall or floor for the exhaust
duct.
Do Not cut a joist or stud unless absolutely
necessary. If a joist or stud must be cut, then a
supporting frame must be constructed.
Determine which venting method to use. See
“Venting methods,” Page 2.
Next, determine the equivalent duct length using
chart on Page 3. This cooktop is equipped with a
dual range blower. The equivalent duct length (not
actual) determines whether blower is set at the
“Low” or “High” range. The blower is set at the
“Low” range setting at the factory.
The blower housing must be rotated or swiveled to
the proper angle needed for your installation. The
blower can be swiveled 90°. The blower maybe
rotated horizontally or vertically. Reach through the
ventilation chamber to loosen, but Do Not remove,
the nuts around blower inlet to adjust the blower.
This downdraft cooktop is rated at 60 feet of
straight duct.
• If duct length is 10 feet (3 m) or less, 5" diameter
round ductwork may be used.
• If duct length is more than 10 feet (3 m), use 6"
diameter round or 3-1/4" x 10" rectangular duct.
Thermal breaks: In areas of extreme cold weather, it
may be necessary to provide a short length of
nonmetallic duct as close to the wall as possible to
prevent thermal conduction along the metal duct.
For altitudes above 4,500 ft (1,350 m), reduce
recommended duct run by 20%.
For the most efficient and
quietest operation:
Use 26-gauge minimum galvanized or 25-gauge
minimum aluminum metal duct. Poor-quality
pipe fittings can reduce air flow. (Note: Local
codes may require a heavier-gauge material.)
Flexible metal duct is Not recommended.
Do Not exhaust more than one downdraft
cooktop into a single duct system.
The length of duct and number of elbows
should be kept to a minimum to provide
efficient performance.
The size of the duct should be uniform.
Use no more than three 90° elbows.
Do Not install two elbows together.
Make sure there is a minimum of 18" (45.7 cm)
of straight duct between the elbows if more
than one elbow is used. (Elbows too close
together cause excess turbulence that reduces
airflow.)
Do Not use a 5" elbow in a 6" or 3-1/4" x 10"
system. Instead, use a 5" to 6" transition
followed by a 6" elbow, or a 5" to 3-1/4" x 10"
elbow transition.
Do Not reduce back to 5" system after using 6"
or 3-1/4" x 10" fittings.
Avoid forming handmade crimps. Handmade
crimps may restrict airflow.
Use the recommended duct caps for proper
performance. If an alternate wall or roof cap is
used, be certain cap size is not reduced and that
it has a backdraft damper.
Use duct tape to seal all joints in the duct
system.
Use caulking to seal exterior wall or roof
opening around the cap.
The cooktop may be vented through the rear wall or
floor. Common venting methods and the types of
materials needed are shown.
Make sure there is proper clearance within the wall or
floor for exhaust duct before making cutouts.
