Gas connection INSTALLATION
3. GAS CONNECTION
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”.
In The Commonwealth Of Massachusetts
This product must be installed by a licensed plumber or gas fitter when installed within the Commonwealth
of Massachusetts.
A ”T” handle type manual gas valve must be installed in the gas supply line to this appliance.
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 (1,24 kPa = 12,4 mbar) on
natural gas, or a manifold pressure of 11” of Water
Column (2,74 kPa = 27,4 mbar) 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 (1,49 and 2,49 kPa).
For LP gas, the pressure supplied must be between 12”
and 13” of water column (3 and 3,24 kPa).
When checking for proper operation of the regulator, the
inlet pressure must be at least 1” (0,25 kPa) 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 (1,5 m) 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 test
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.
