Step 5:
Verify the type of gas being used at the installation site.
As shipped from the factory, units are configured
for use with only natural gas or propane (LP) gas.
Make certain the range matches the type of gas
available at this location. These ranges are NOT
convertible between different types of gas.
For installation of the appliance at high altitude, please
consult your local gas company for their recommen-
dation of the correct orifice sizes and any other
necessary adjustments that will provide proper gas
combustion at specified altitudes.
CAUTION
When connecting unit to propane gas, make
certain the propane gas tank is equipped with its
own high pressure regulator in addition to the
pressure regulator supplied with the appliance.
The pressure of the gas supplied to the appli-
ance regulator must not exceed 14"
(34.9 mb) water column.

WARNING
Gas Requirements and Hookup
HOOK UP
• A manual gas shut-off valve must be installed
external to the appliance, in a location accessible
from the front, for the purpose of shutting off the
gas supply. The supply line must not interfere with
the back of the unit. Make sure the gas supply is
turned off at the manual shut-off valve before
connecting the appliance.
• The range is supplied with its own pressure regu-
lator that has been permanently mounted within
the range body.
Use 3/4" flex line to connect between the gas
supply and the appliance inlet pipe, which exits the
upper rear of the appliance. The appliance pipe
connection has a 3/4" NPT external thread and a
1/2" NPT internal thread. (See Photo A.) Use
caution to avoid crimping the 3/4" flex line when
making bends.
• The gas supply connections shall be made by a
competent technician and in accordance with
local codes or ordinances. In the absence of a
local code, the installation must conform to the
National Fuel Gas Code ANSI Z223.1iNFPA54-
current issue.
Always use pipe sealing compound or Teflon®
tape on the pipe threads, and be careful not to
apply excessive pressure when tightening the
fittings.
• Leak testing of the appliance shall be in accor-
dance with the following instructions.
• Turn on gas and check supply line connections
for beaks using a soap and water solution,
Bubbles forming indicate a gas leak. Repair all
beaks immediately after finding them.
• Do not use a flame of any kind to check for
gas leaks.

Gas line must not come in contact with any
components inside back cover of range. Run
gas line in channel in back of range.
Use 3/4" flex line to connect between the gas supply
and the appliance manifold pipe, which exits the
upper left rear of the appliance.
