Installation Instructions
PROVIDE ADEQUATE GAS SUPPLY
Your range is designed to operate at a pressure of 5"
of water column on natural gas or, if designed for LP
gas (propane or butane), 20" of water column.
Hake sure you are supplying your range with the type
of gas for which it is designed.
This range is convertible for use on natural or propane
gas. If you decide to use this range on LP gas, conversion
must be made by a qualified LP installer before
attempting to operate the range on that gas.
For proper operation, the pressure of natural gas supplied
to the regulator must be between 5" and 13" 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 r' 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 1/2"
and be 5 feet in length for ease of installation. In Canada,
flexible connectors must be single wall metal connectors
no longer than 6 feet in length.
CONNECT THE RANGE TO GAS
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
gou 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.
a.
Install a manual gas line shut-off valve in the gas line
in an easily accessed location outside of the range.
Hake sure everyone operating the range knows where
and how to shut off the gas supply to the range.
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:
DONOTUSE 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.
