Gas Supply Requirements

Observe all governing codes and ordinances.

IMPORTANT: 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 or CAN/CGA B149 - latest

edition.

IMPORTANT: Leak testing of the cooktop must be conducted

according to the manufacturer’s instructions.

Type of Gas

Natural Gas:

This cooktop is factory set for use with Natural gas. If converting

to LP gas, see the “LP Gas Conversion” instructions provided in

the package containing literature. The model/serial/rating plate

located on bottom of the cooktop has information on the types

of gas that can be used. If the types of gas listed do not include

the type of gas available, check with the local gas supplier.

LP Gas Conversion:

Conversion must be done by a qualiﬁed service technician.

No attempt shall be made to convert the cooktop from the gas

speciﬁed on the model/serial/rating plate for use with a different

gas without consulting the serving gas supplier. See the “Gas

Conversion” instructions provided in the package containing

literature.

Gas Supply Line

■ Provide a gas supply line of

⁄

" (1.9 cm) rigid pipe to the

cooktop location. A smaller size pipe on longer runs may

result in insufﬁcient gas supply. Pipe-joint compounds

that resist the action of LP gas must be used. Do not use

TEFLON

®†

tape. With LP gas, piping or tubing size should be

" minimum. Usually, LP gas suppliers determine the size

and materials used in the system.

Flexible metal appliance connector:

■ If local codes permit, use a

" or

" I.D. ﬂexible stainless

steel tubing gas connector, designed by CSA to connect the

cooktop to the rigid gas supply line.

■ A

" male pipe thread is needed for connection to the

female pipe threads of the inlet to the cooktop pressure

regulator.

■ Do not kink or damage the ﬂexible metal tubing when

moving the cooktop.

■ Must include a shut-off valve:

The supply line must be equipped with a manual shut-off

valve. This valve should be located in the same room. It must

be accessible without removing the cooktop, and it should

be in a location that allows ease of opening and closing. Do

not block access to shut-off valve. The valve is for turning on

or shutting off gas to the cooktop.

Gas Pressure Regulator

The gas pressure regulator supplied with this cooktop must be

used. The inlet pressure to the regulator should be as follows

for proper operation:

Natural Gas:

Minimum pressure: 5" (12.7 cm) WCP

Maximum pressure: 7" to 14" (17.8 cm to 35.5 cm) WCP

LP Gas:

Minimum pressure: 10" (25.4 cm) WCP

Maximum pressure: 14" (35.5 cm) WCP

Contact local gas supplier if you are not sure about the inlet

pressure.

Burner Input Requirements

Input ratings shown on the model/serial/rating plate are for

elevations up to 2,000 ft (609.6 m).

For elevations above 2,000 ft (609.6 m), ratings should be

reduced at a rate of 4% for each 1,000 ft (304.8 m) above

sea level (not applicable for Canada).

Gas Supply Pressure Testing

Gas supply pressure for testing regulator must be at least 1"

water column pressure above the manifold pressure shown on

the model/serial/rating plate.

Line pressure testing above ½ psi gauge (14" WCP)

The cooktop and its individual shut-off valve must be

disconnected from the gas supply piping system during any

pressure testing of that system at test pressures in excess

psi (3.5 kPa).

Line pressure testing at ½ psi gauge (14" WCP) or lower

The cooktop must be isolated from the gas supply piping

system by closing its individual manual shut-off valve during

any pressure testing of the gas supply piping system at test

pressures equal to or less than

psi (3.5 kPa).

WARNING

Explosion Hazard

Use a new CSA International 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" (36 cm) 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.
