Installing the Rear Filler
1
Using a screwdriver, remove the upper four
screws that attach the rear bracket and loosen
the lower two screws.
2
Place the rear filler on the rear bracket.

Providing Adequate Gas
Supply
The range is designed to operate at a pressure of
5" of water column on natural gas or 10" of water
column on LP.
Make sure you are supplying the range with the type
of gas for which it is configured.
This range is convertible for use on natural or LP gas.
When using this range on LP gas, conversion must
be made by a qualified LP installer before attempting
to operate the range.
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 to the regulator
must be between 10" and 13" of water column. When
checking for correct operation of the regulator, the
inlet pressure must be at least 1" more than the
operating (manifold) pressure as given above.
The pressure regulator located at the inlet of the
range must remain in the supply line regardless of
which type of 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
/ " and a maximum length of 5 feet. In Canada,

flexible connectors must be single wall metal
connectors less than 6 feet in length.

Connecting the Range to Gas

This appliance must be installed in accordance 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.
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 shall 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.
1
Install a male / " or
1
2
NPT internal thread of the manual shut-off valve,
taking care to back-up the shut-off valve to keep
it from turning.
2
Install a male / " 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.
3
Connect a flexible metal appliance connector to
the adapter on the range. Position the range to
permit connection at the shut-off valve.
4
When all connections have been made, be sure
all range controls are in the Off position and turn
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.
WARNING
• Do not use a flame to check for gas leaks.
• 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
• The appliance must be isolated from the gas
supply piping system by closing its individual
manual shut-off valve during any pressure
testing of the gas supply piping system at test
pressures equal to or less than
