slide under the bracket, as shown in Figure 7.
4. If the range is moved to a new location, the Anti-Tip
Device must be removed and reinstalled.
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.
High Altitude — For altitudes above 2,000 feet (610 m)
elevation above sea level, adjustments can be made with
the High Altitude Packet included with the unit. If flame
performance is satisfactory, the contents in this packet will
not be required. It is required that a Certified Professional
make the high altitude adjustments during installation.
WARNING
Gas line must not come in contact with any components
inside back cover of range.

Inlet Connection: ½'' (13 mm) NPT internal
[Minimum ¾" (19 mm) 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: ½'' (13 mm) NPT internal
[Min. 3/4" (19 mm) 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)
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.
1. 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.
2. Use a ¾'' (19 mm) flex line to connect between the gas
supply and the appliance gas inlet. The gas supply line
connection is located at the lower right portion of all
range models (see Figure 8). The appliance gas inlet
connection is ½'' (12.7 mm) NPT.
• Use caution to avoid crimping the ¾'' (19 mm) flex
line when making bends. Suggested length of flex
line is 48" (1219 mm); however, please check local
codes for your area's requirements before
installation.
