Step 5: Gas Requirements
and Hookup
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 recommendation
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
appliance regulator must not exceed 14" (34.9
mb) water column.
Natural Gas Requirements:
Inlet Connection: 1/2" NPT internal
(Minimum 3/4" dia. flex line.)
Supply Pressure: 6" min. to 14" max. water column.
(14.9 to 34.9 mb)
Manifold Pressure: 5" water column (12.5 mb)
Propane Gas Requirements:
Inlet Connection: 1/2" NPT internal
(Minimum 3/4" dia. flex line.)
Supply Pressure: 11" min. to 14"max. water column.
(27.4 mb to 34.9 mb)
Manifold Pressure: 10" water column (24.9 mb)
WARNING
Gas line must not come in contact with any
components inside back cover of range.

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 regulator
that has been permanently mounted within the range
body.
• Use 3/4" flex line to connect between the gas supply
and the appliance gas inlet, located at the lower right
portion of the range. (See Figure 8.) The appliance inlet
pipe connection is 1/2" NPT. Use caution to avoid
crimping the 3/4" flex line when making bends.
Suggested length of flex line is 48", however, please
check local codes for your area's requirements before
installation.
• The gas supply connections shall be made by a
competent technician and in accordance with local
codes or ordinances. In the absence of local codes, the
installation must conform to the National Fuel Gas Code
ANSI Z223.1/NFPA54- 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 accordance with
the following instructions.
• Turn on gas and check supply line connections for
leaks using a soap and water solution.
• Bubbles forming indicate a gas leak. Repair all leaks
immediately after finding them.
WARNING
Do not use a flame of any kind to check for
gas leaks.
CAUTION:
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 1/2 psig (3.5kPa.).
The appliance and its individual shut off valve
must be disconnected from the gas supply piping
system during any pressure testing of the system
at test pressures in excess of 1/2 psig (3.5kPa.).
When checking the manifold gas pressure, the
inlet pressure to the regulator should be at least
6.0" (14.9 mb) W.C. for natural gas or 11.0" (27.4
mb) for propane.
Do not attempt any adjustment of the pressure
regulator.
