Electrical Code ANSI/NFPA No. 70, latest edition.

1. Providing Adequate Gas Supply

This cooktop is designed to operate at a pressure
of 5” of water column with natural gas or 10” of
water column with LP, propane or butane gas.

Make sure you are supplying your cooktop with
the type of gas for which it is designed.

This cooktop is convertible for use with natural or
propane gas. When using this cooktop with LP gas,
the conversion must be made by a qualified LP
installer before attempting to operate the cooktop
using that gas.

For correct operation, the pressure of natural gas
supplied to the regulator should be between 5”
and 13” of water column.

For LP gas, the pressure supplied must be between
10” and 13” of water column.

When checking for correct operation of the
regulator, the inlet pressure must be at least 1”
more than the operating (manifold) pressure as
given above.

The pressure regulator located at the inlet of the
cooktop manifold must remain in the supply line
regardless of whether natural or LP gas is being
used.

A flexible metal appliance connector used to
connect the cooktop to the gas supply line must

have an I.D. of 5/8” and must be a maximum of 3
feet in length for easy installation. In Canada,
flexible connectors should be single wall metal
connectors less than 6 feet in length.

2. Connecting the Cooktop to Gas

Shut off the main gas supply valve before
removing the old cooktop and leave it off until the
new hook-up has been completed. Don’t forget to
relight the pilot on other gas appliances when you
turn the gas back on.

Because hard piping restricts movement of the
cooktop, the use of a CSA International-certified
flexible metal appliance connector is
recommended unless local codes require a hard­piped connection.

Never reuse an old connector when installing a
new cooktop. If the hard piping method is used,
you must carefully align the pipe; the cooktop
cannot be moved after the connection is made.

To prevent gas leaks, put pipe joint compound on
all male (external) pipe threads.

1 Install a manual gas line shut-off valve in the

gas line in an easily accessed location outside
of the cooktop. Be sure everyone operating
the cooktop knows where and how to shut off
the gas supply to the cooktop.

2 Install a male 1/2” flare union adapter to the

1/2” NPT internal thread at the inlet of the
pressure regulator. Use a backup wrench on
the pressure regulator fitting to prevent
damage. Make sure that the access cap on the
gas regulator is facing the front of the cabinet
and is easily accessible through the cabinet
doors.

3 Install a male 1/2” or 3/4” flare union adapter

to the NPT internal thread of the manual shut­off valve, taking care to back-up the shut-off
valve to keep it from turning.

4 Connect a flexible metal connector to the

adapter on the cooktop. Position the cooktop
to permit connection at the shut-off valve.

5 When all connections have been made, be

sure all cooktop controls are in the off
position and turn on the main gas supply
valve. Check for gas leaks using a manometer.

WARNING

NOTE

en-us_main.book.book Page 9 Friday, February 16, 2024 1:13 PM

9INSTALLATION

If a manometer is not available, turn the gas
supply to the cooktop on and use a liquid leak
detector at all joints and connections to check
for leaks. Tighten all connections, if necessary,
to prevent gas leakage in the cooktop or
supply line.

• DO NOT USE A FLAME TO CHECK FOR GAS LEAKS.

• The appliance and its individual shutoff valve
must be disconnected from the gas supply
piping system during any pressure testing of
that system at test pressures in excess of 1/2 psi
(3.5 kPa).

• The appliance must be isolated from the gas
supply piping system by closing its individual
manual shutoff valve during any pressure
testing of the gas supply piping system at test
pressures equal to or less than 1/2 psi (3.5 kPa).
