The range is designed to operate at a manifold
pressure of 4’’ of water column on natural gas. A
conversion kit for LP gas (propane or butane) is
supplied with the range. When converted to LP gas,
a pressure of 10’’ of water column is required.
Make sure you are supplying your range with the
correct type of gas.
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. This must be
done before the range can be used on LP gas.
For proper operation, the pressure of natural gas
supplied to the regulator must be between 4 1 /
2
’’ 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 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 1/2’’ and be 5 feet in length for ease of installation.
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.
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 elbow 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 backup 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. Use a product specifically
manufactured for leak detection. Leak testing of
the appliance shall be conducted in accordance to
the manufacturer’s instructions.
CAUTION: DO NOT USE A FLAME
TO CHECK FOR GAS LEAKS.
When using test pressures greater than 1/2 psig
(3.5kPa) 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 (3.5kPa) or less to test the
gas supply system, simply isolate the range from the
gas supply system by closing the individual shut-off
valve.
