La Cornue CornuFé 1908 - 36 - Manual (Page 28)

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" hand le type manual gas valve must be installed in the gas supply line to this
appliance.
All La Cornue ranges are fully assembled and equipped for use with the type of gas shown on the
rating plate of the appliance.
The CornuFé 1908 - 36" stove is fitted with orifices for natural gas, pressure 4" WC.
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. A conversion kit for Propane gas is supplied
with the range. See the "Conversion to Propane Gas" instruction for more details.
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 4" of Water Column on natural gas, or
a manifold pressure of 10" of Water Column on LP gas (Propane).
For proper operation, the pressure of natural gas supplied to the regulator must be between 4 1 / 2 "
and 10" of water column.
For LP gas, the pressure supplied must be between 10" 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 4" of water column pressure.
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.
