Connect The Range To Gas - LG LRG30355 Installation Instructions Manual

2. CONNECT THE RANGE TO GAS

Shut off the main gas supply valve before
disconnecting the old range and leave it off
until the new hook-up 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.
Never use an old connector when installing a
new range. If the hard piping method is used,
you must carefully align the pipe; the range
cannot be moved after the connection is made.
To prevent gas leaks, put pipe joint compound
on, or wrap pipe thread tape with Teflon*
around, all male (external) pipe threads.
A
Install a manual gas line shut-off valve in the
gas line in an easily accessed location
outside of the range. Make sure everyone
operating the range knows where and how
to shut off the gas supply to the range.
B
Install male 1/2" flare union adapter to the
1/2" NPT internal thread at inlet of regulator.
Use a backup wrench on the regulator fitting
to avoid damage. When installing the range
from the front, remove the 90° elbow for
easier installation.

C
Install 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.
D
Connect flexible metal appliance connector
to the adapter on the range. Position range
to permit connection at the shut-off valve.
E
When all connections have been made,
make sure all range controls are in the off
position and turn on the main gas supply
valve. Use a liquid leak detector at all joints
and connections to check for leaks in the
system.
WARNING!
DO NOT USE A FLAME TO CHECK FOR
GAS LEAKS.
When using test pressures greater than 1/2 psig
to pressure test the gas supply system of the
residence, disconnect the range and individual
shut-off valve from the gas supply piping. When
using test pressures of 1/2 psig or less to test
the gas supply system, simply isolate the range
from the gas supply system by closing the
individual shut-off valve.
