The installation of your La Cornue appliance must conform with local codes or, in the
absence of local codes, in the USA with the "National Fuel Gas Code", ANSI Z223.1, latest
edition, and, in Canada, with CAN/CGA - B149.1, and CAN CGA - B149.2, "Installation Code
for Gas Burning Appliances".
All La Cornue ranges and cooktops are fully assembled and equipped for use with the type of gas
shown on the rating plate of the appliance.
If no special instructions were mentioned upon ordering, the stove is fitted with orifices for natural
gas.
Prior to installation, ensure that the local distribution conditions (nature of the gas and
gas pressure) and the adjustment of the appliance are compatible.
The range is designed to operate at a manifold pressure of 5’’ of Water Column on natural gas, or
a manifold pressure of 11’’ of Water Column on LP gas (Propane).
If the range is to be used on LP gas, a qualified LP installer must convert it. We recommend that
the range be converted before installation.
For proper operation, the pressure of natural gas supplied to the regulator must be between 6’’ and
10’’ of water column.
For LP gas, the pressure supplied must be between
12’’ and 13’’ of water column.
When checking for proper operation of the
regulator, the inlet pressure must be at least 1’’
greater than the operating (manifold) pressure as
given above.
The pressure regulator located at the inlet of the
range 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 range to the gas supply line should
have an I.D. of ½’’ and be 5 feet in length for ease
of installation.
The gas regulator on the appliance is set at the factory for pressures given by regulations.
For the La Cornue ranges and hobs the regulator and the pressure tap can be found on the hob’s
manifold located by the 2 left gas burners
Connect the Range to the Gas Supply
Shut off the main gas supply valve before disconnecting the old
range and leave it off until the new hookup 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 range, the use of
a CSA International certified flexible metal appliance connector
is recommended unless local codes require a hard piped
connection.
