CAUTION
The appliance must be isolated from the gas supply piping
system by closing its individual manual shutoff valve
during any pressure testing of the gas supply piping
system at test pressures equal to or less than ½ psi
(3.5 kPa).
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" water column
(34.9 mbar).
WARNING
DO NOT use a flame of any kind to check for gas leaks.
IMPORTANT: Do not ground to a gas pipe.
Verify the type of gas being used at the installation site.
Make certain the range matches the type of gas available
at this location.
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.
5.1 High altitude installation
This appliance has been tested for operation up to an
¡
altitude of 10,100 ft (3,078 m) elevation above sea level.
A high altitude kit is required for natural gas above
¡
5,400 ft (1,646 m) elevation above sea level, and for
propane (LP) above 10,000 ft (3,048 m) elevation above
sea level.
16
If desired, for altitudes above 2,000 ft (610 m) elevation
¡
above sea level, adjustments can be made to the
rangetop burners with an adjustment kit. If flame
performance is satisfactory, adjustment will not be
required.

5.3 Connecting the gas supply
Make sure the gas supply is turned off at the manual
1.
shut-off valve before connecting the appliance.
Use a ¾" (19 mm) flex line to connect between the gas
2.
supply and the appliance gas inlet. The gas supply line
connection is located at the lower right portion. 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.
A ¾" (19 mm) external threads
½" (12.7 mm) internal threads
B ¾" (19 mm) flex line
Use pipe sealing compound or Teflon® tape on the pipe

threads. DO NOT apply sealing compound or tape to
flare fittings. Take care not to apply excessive pressure
when tightening the fittings.
