other naturally vented systems. To minimize
the chance of interference with such naturally
vented systems, follow the heating equipment
manufacturer’s guidelines, and local codes.
Also follow the guidelines in ASHRAE
Standard 62-1989, “Ventilation for Acceptable
Indoor Air Quality”, section 5.8. When
following these guidelines, be sure to test for
proper airflow direction into the draft hood of
a naturally vented gas furnace or water heater.
This can be checked by striking a match,
blowing it out, and while it is still smoking,
holding it near the draft hood relief opening.
If smoke is drawn into the opening, vent flow
is in the proper direction. If the ASHRAE
Standard 62 guidelines are not satisfied, a
positive supply of outside air may have to be
supplied.
Wiring must conform to the requirements of
the National Electrical Code. If the electric
supply provided does not meet the specifications, call a licensed electrician.
WARNING:
Any home ventilation system, such as a
cooktop with a downdraft mechanism, may
interfere with the proper flow of exhaust
products or combustion air required by gas
furnaces, gas water heaters, fireplaces, or

These cooktops are supplied with 1/2" NPT
male gas connections. The connection for
models with right hand controls is on the
bottom right corner, and left hand control
models on the left corner.
• Gas components cannot be converted to LP
gas operation.
• Make gas connection through the rear wall,
or on the cabinet floor at the rear.
• For rigid connection, locate pipe stub:
–4-7/16" from center line of appliance,
–on the back wall, at least 12" below
countertop,
–on the floor, 2-1/2" forward of the back of
the countertop cutout.
For flexible connection, locate pipe stub on
floor or back wall in a convenient location.
• Install a manual shut-off valve in the gas line
in an easily accessible location.
The radiant component operates on 240/208
volt, 60 Hz. Updraft grill and downdraft grill
components operate on 240 volt, 60 Hz. Gas
and downdraft vent components operate on
120 volt, 60 Hz. from a separate junction box.
A dedicated circuit, protected by a time delay
fuse or circuit breaker is required for
cooktops. The downdraft vent requires an
appliance circuit with a time delay fuse of
circuit breaker.

Joining Cooktop to Downdraft Vent
• Remove all grates, knobs, burner caps and drip
pans.
• Lay cooktop upside down.
• Remove endcap on side of cooktop to be joined
by removing three nuts with a 5/16" nutdriver.
Important: Pre-tap holes in downdraft joiner and
endcaps by driving supplied screws through
holes and then backing out before installation.
This will make the joining process easier.
• Replace endcap with downdraft joiner strip
using the same three nuts.
–If the vent is to be installed at the end of
the countertop opening, attach downdraft
endcap to that side.
• Place the downdraft vent and cooktop into the
cutout.
• Remove two screws from the front of cooktop
chassis. Drive the two screws into holes below
the downdraft vent flange as shown. Use a
phillips screwdriver bit socket.
• If downdraft vent is installed at the end of the
cutout, secure the downdraft endcap to the
countertop by driving two phillips head screws
as shown.
• To finalize installation, proceed to “Securing
cooktop(s) to countertop.
• If additional cooktop(s) are to be installed,
proceed to “Joining additional cooktop to
downdraft vent or downdraft grill.”

Gas
• Install the supplied pressure regulator in gas
supply line as close to the cooktop inlet as
possible. Allowances for ventilation ducting
may be required.
–The regulator should be installed with the
arrow pointing in the direction of gas flow.
• Install a manual gas shut-off valve where it
will be easily reached. Be sure the user knows
where and how to shut off the gas supply.
• Appropriate flare union adapters are
required at each end of a flexible connector.
• Turn on the gas and check for leaks. Use a
liquid leak detector at all connections in the
system. A pressure test fitting is located on
the pressure regulator.
CAUTION
Do not use a flame to
check for leaks.

Connect electrical to downdraft vent
• Connect the 3-pin plastic plug from the
blower/motor assembly to the 3-pin plastic
socket on the underside of the vent controls.
• Fasten the wire box on the conduit over the
plug and onto the bottom of the control box
with screws provided.
The blower conduit is long enough to reach
the vent connection when installed in the
cabinet below. The conduit will also reach
some blower installations below the cabinet
floor.
• If the blower conduit is not long enough to
reach the vent connection, the leads can be
extended.
To add conduit length:
• Install an appropriate junction box near the
blower.
• Remove the wire box from the end of the
blower conduit.
• Cut the leads approximately 3" from the
plug.
• Cut a length of electrical cable to reach the
junction box. Use 14 gauge min. electrical
cable (or conform to local codes).
• Attach the wire box and plug to one end of
the cable. Connect opposite end of cable to
blower leads in the junction box.
