Connecting the Range to Gas
Isolate the range from the gas supply system by closing its individual shut-off valve during any pressure testing of the gas supply system at test pressures equal to or less than 1/2 psi (3.5 kPa).
The appliance 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 of 1/2 psi (3.5 kPa).
Shut off the range gas supply valve before removing the old range and leave it off until the new hook-up has been completed.
Because hard piping restricts movement of the range, a CSA International-certified flexible metal appliance connector should be used unless local codes require a hard-piped connection.
A manual valve must be installed in an accessible location in the gas piping external to the appliance for the purpose of turning on or shutting off gas to the appliance.
Never reuse an old connector when installing a new range.
To protect against gas leaks, use a qualified pipe joint sealant on all external threads.
Install a male 1/2" or 3/4" flare union adapter to the NPT internal thread of the manual shut-off valve, taking care to back-up the shut-off valve to keep it from turning.
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.
Check that the gas pressure regulator valve is in the open position.

NoteThe gas pressure regulator valve is open when shipped. If the range does not work properly after installation, make sure the regulator valve is still open.
Connect a flexible metal appliance connector to the adapter on the range. Position the range to permit connection at the shut-off valve.
When all connections have been made, be sure all range controls are in the OFF position and the pressure regulator valve is open before turning on the main gas supply valve.
Gas leaks may occur in your system and create a hazard. Gas leaks may not be detected by smell alone.
Check all gas connection joints and fittings for leaks with a non-corrosive leak detection fluid, then wipe off.
Gas suppliers recommend you purchase and install a UL approved gas detector. Install and use in accordance with the installation instructions.
WarningDo not use a flame to check for gas leaks.
NoteInstallation must conform with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 or, in Canada, the Natural Gas and Propane Installation Code, CSA B149.1.
