Supply
Location
• Gas components are designed to operate on
natural gas at 4" water column pressure.
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.

Supply
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.
• If local codes permit, more than one cooktop
can be used on the same branch circuit. See
local codes or the National Electrical Code
for circuit demand loads.
WARNING: DO NOT USE AN EXTENSION
CORD WITH THESE APPLIANCES.
Important:
12" min. is specified to allow space for shut-off valve
if supply is opted to enter from rear.
Note:
Both left and right-controlled gas components are
illustrated together in order to compare their supply rough-in
locations.
