Explosion Hazard
Use a new AGA or CSA approved gas
supply line.
Install a shut-off valve.
Securely tighten all gas connections.
If connected to LP, have a qualified
person make sure gas pressure does
not exceed 14" water column.
Examples of a qualified person
include licensed heating personnel,
authorized gas company personnel,
and authorized service personnel.
Failure to do so can result in death,
explosion, or fire.
Observe all governing codes and
ordinances.
Important: Cooktop must be connected
to a regulated gas supply.
This installation must conform with all local
codes and ordinances. In the absence of local
codes, installation must conform with
American National Standard, National Fuel
Gas Code ANSI Z223.1 — latest edition* and
all local codes and ordinances.
Copies of the standards listed above may be obtained
from:
* CSA International
8501 East Pleasant Valley Road
Cleveland, Ohio 44131-5575

Input ratings shown on the model/serial rating
plate are for elevations up to 2,000 feet
(610 m). For elevations above 2,000 feet
(610 m), ratings are reduced at a rate of 4% for
each 1,000 feet (305 m) above sea level.
Type of gas: This downdraft cooktop is factory
set for use with Natural gas. It is design-

certified by CSA International for Natural or
L.P. gas usage with appropriate conversion.
(See “Gas conversion” instructions, Page 7).
The model/serial rating plate (located on the
right side of the downdraft plenum) lists the
type of gas that can be used. If the type of gas
listed does not agree with the type of gas
available, check with the local gas supplier.
Conversion must be done by a qualified
service technician.
Gas supply line: With Natural gas, provide a
gas supply line of 3/4" rigid pipe to the
downdraft cooktop location. With L.P. gas,
piping or tubing can be 1/2" minimum. A
smaller size pipe on long runs may result in
insufficient gas supply. Usually, L.P. gas
suppliers determine the size and materials
used on the system.
Pipe-joint compounds made for use with L.P.
gas must be used.

Flexible metal appliance connector: If local
codes permit, a new AGA or CSA designcertified, 4-5 foot long, 1/2" or 3/4" I.D., flexible
metal appliance connector is recommended
for connecting the cooktop to the gas supply
line. A 1/2" male pipe thread is needed for
connection to pressure regulator female pipe
threads. Do Not kink or damage the flexible
metal tubing when moving the downdraft
cooktop.

If rigid pipe is used as a gas supply
line, a combination of pipe fittings
must be used to obtain an in-line
connection to the downdraft
cooktop. All strains must be removed from the
supply and fuel lines so cooktop will be level
and in line.

shutoff valve
“open” position
to downdraft
cooktop
to gas
supply

Shutoff valve: The supply line must be
equipped with an approved manual shutoff
valve. This valve should be located in the
same room as the downdraft cooktop and
should be in a location that allows ease of
opening and closing. The valve is for turning
on or shutting off gas to the appliance. Do Not
block access to shutoff valve.
Pressure regulator: The gas pressure
regulator supplied with this downdraft
cooktop must be used. The regulator must be
checked at a minimum 1-inch water column
above the set pressure. The inlet pressure to
the regulator should be as follows for
operation and for checking the regulator
setting:
NATURAL GAS:
Minimum pressure: 6 inches WC
Maximum pressure: 14 inches WC
L.P. GAS:
Minimum pressure: 11 inches WC
Maximum pressure: 14 inches WC
Line pressure testing above 1/2 psi gauge
(14" WC) — The downdraft cooktop and its
individual shutoff valve must be disconnected
from the gas supply piping system during any
pressure testing of that system at test
pressures greater than 1/2 psi (3.5 kPa).
Line pressure testing at 1/2 psi gauge
(14" WC) or lower — The downdraft cooktop
must be isolated from the gas supply piping
system by closing its individual manual
shutoff valve during any pressure testing of
that system at test pressures equal to or less
than 1/2 psi (3.5 kPa).

Venting requirements
Venting system must terminate to the
outside.
Do Not terminate the vent system in an
attic or other enclosed space.
Do Not use 4-inch (10 cm) laundry-type
wall caps.
Use metal vent only. Exception: See
“optional venting under a concete slab”,
in “Venting methods” on Page 4. Rigid
metal vent is recommended. Do not use
plastic or metal foil vent.
To reduce risk of fire and to properly
exhaust air, be sure to vent air outside.
Do Not vent exhaust air into spaces
within walls or ceilings or into attics,
crawl spaces or garages.

Vent materials needed for installation are
not supplied.
Before making cutouts, make sure there is
proper clearance within the wall or floor for
the exhaust vent.
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.

Page 3

Determine which venting method to use. See
“Venting methods,” Page 4.
Next, determine the equivalent vent length
using the chart on page 4. This cooktop is
equipped with a dual range blower. The
equivalent vent 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 may be rotated horizontally or
vertically. Reach through the ventilation
chamber to loosen, but Do Not remove, the
nuts around the blower inlet to adjust blower.
This downdraft cooktop is rated at 60 feet of
straight vent.
• If vent length is 10 feet or less,
5" diameter round vent MUST be used.
• If vent length is more than 10 feet, use
6" diameter round or 3-1/4" x 10" rectangular
vent.
Thermal breaks: In areas of extreme cold
weather, it may be necessary to provide a
short length of nonmetallic vent as close to
the wall as possible to prevent thermal
conduction along the metal vent.
For altitudes above 4,500 ft, reduce
recommended vent run by 20%.

For the most efficient and
quietest operation:
Use 26-gauge minimum galvanized or
25-gauge minimum aluminum metal vent.
Poor-quality pipe fittings can reduce air
flow. (Note: Local codes may require a
heavier-gauge material.) Flexible metal
vent is not recommended.
Do Not exhaust more than one downdraft
cooktop into a single vent system.
The length of vent and number of elbows
should be kept to a minimum to provide
efficient performance.
The size of the vent should be uniform.
Use no more than three 90° elbows.
Do Not install two elbows together.
Make sure there is a minimum of 18"
of straight vent 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 vent 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 vent
system.
Use caulking to seal exterior wall or roof
opening around the cap.

Determine range blower setting.

This cooktop is equipped with a dual range blower. It is factory set at
“Low” range to be used for equivalent vent length runs of 30 feet
(9.1m) or shorter. If the equivalent vent length exceeds 30 feet (9.1m),
the blower must be shifted to “High” range. Do Not shift to “High”
range for runs shorter than 30 feet (9.1m). Using the “High” range on
shorter runs will cause excessive noise and conditioned air loss, and
will affect the flame pattern of gas burners.
List the number of each piece and length of straight vent you will use.
Multiply the equivalent length by the number of pieces. Add the totals
to get the total equivalent length of your system.

install cooktop.
Failure to do so can result in back or
other injury.

C Vent connection

B Installation

Insert downdraft cooktop into
cutout. Check that:
cooktop is centered in cutout.
front edge of downdraft cooktop is at
least 1-1/2" (3.8 cm) from front edge of
countertop and parallel to countertop.
side edge of cooktop is at least 2 inches
(5.1 cm) from side wall.

Connect vent system. See
“Venting requirements,” pages 3-4. Use
duct tape to seal all joints. Vent must end
with a wall or roof cap outside the
building.

1.
2.

Remove the downdraft cooktop
from packaging.

Check equivalent vent length to
determine if blower should be set at
“Low” or “High” range (see chart on page
4 to determine equivalent vent system
length). If vent system length is greater
than 30 feet (9.1m), shift the blower range
setting from “Low” to “High” (see
instructions on page 4 for shifting the
blower range).
If blower must be shifted to “High” range,
do it now.

D Gas connection
IMPORTANT: All connections must be
wrench-tightened. Do Not make
connections to the gas regulator too tight.
Making the connection too tight may crack
the regulator and cause a gas leak. Do Not
allow the regulator to turn on the pipe when
tightening fittings.

All connections must be wrench-tightened.

Open the manual shutoff valve in
the gas supply line. Wait a few minutes for
the gas to move through the line.

Use a brush and liquid detergent to
test all gas connections. Bubbles around the
connections will indicate a leak. If a leak
appears, shut off gas valve controls and
adjust connections. Then check connections
again. NEVER TEST FOR GAS LEAKS WITH
A MATCH OR OTHER FLAME. Clean all
detergent from the cooktop.

E Check operation

Push in and turn each surface
burner control knob to “LITE” position and
then to “LO” position. The low flame should
be a minimum, steady blue flame.
Do Not use a metal blade to pry off control
knob; this could damage the product. If the
control knob cannot be easily removed, tuck
a cloth under the knob and pull upward on
cloth with steady, even pressure to remove
knob.

Plug the
power supply cord
into the grounded
outlet.

Check for proper venting:
• Check that the air filter is in place.
• Align the dotted line labeled for “cooktop
models” on the flow tester with the edge
of the intake on the left side of the cooktop
near the center.
• Turn on the downdraft system:
If the card is pulled into the air intake,
your downdraft is working properly.
If the card is not pulled into the system,
see “Venting requirements,” Pages 3-4,
and check vent installation for possible
causes.

If the low flame needs adjusting –
• Remove the control knob and turn the
adjustment screw in the center of the valve
stem. Do Not turn screw more than 1/2
revolution in either direction.
• Replace the control knob. Check the
adjustment by turning the control knob from
“HI” to “LO” several times. The burner is
properly adjusted when the low flame
remains steady and the burner does not go
out.
• Turn control knob to “OFF” position.
• Repeat if necessary for other surface burner.

Electronic ignitions system
Cooktop burners use electronic ignitors in
place of standing pilots. When the cooktop
control knob is turned to the “LITE”
position, the system creates a spark to light
the burner. This sparking continues until the
control knob is turned to the desired setting.

Check each surface burner for
proper flame at “HI” setting. The
small inner cone should have a
very distinct, blue flame that is
1/4" (0.6 cm) to 1/2" long (1.3 cm).
The outer cone is not as distinct as
the inner cone. Turn surface
burner control knobs to “OFF” position.
