Hook Up
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 (Figure 15) 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. Locate the gas supply line connection at the back of
the range (Figure 15).
3. Use a ¾" (19 mm) flex line to connect between the gas
supply and the appliance gas inlet. The appliance gas
inlet connection is ½" (13 mm) NPT (Figure 15).
• 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.
WARNING!
Gas line must not come in contact with any components
inside back cover of range.
4. Use a pipe sealing compound or Teflon
pipe threads. Do not apply sealing compound or tape
to flare fittings. Be careful not to apply excessive
pressure when tightening the fittings.
5. 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.
