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 16).

Gas line must not come in contact with any components
inside back cover of range.
• Use caution to avoid crimping the ¾'' (19 mm) flex
line when making bends.
• Suggested length of flex line is 48" (1219 mm);

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.
WARNING
Do not use a flame of any kind to check for gas
leaks.
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" W.C. (14.9
mb) for natural gas or 11.0" W.C. (27.4 mb) for propane. Do
not attempt any adjustment of the pressure regulator.
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.).
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" water
column (34.9 mb).
Installer is responsible for ensuring that the installation, gas
connections, and grounding comply with all applicable
codes.
