Step 5: Gas Requirements and
Hookup
Verify the type of gas being used at the installation site.
The appliance is shipped from the factory for use with
natural gas. It must be converted for use with propane.
A qualified technician or installer must do the
conversion. Make certain the range matches the type of
gas available at this location.
The field conversion kit for this series of Dual Fuel Ranges
is THERMADOR ® model PLPKIT. Obey all instructions in
PLPKIT for correct conversion of the gas regulator and
settings for the gas valves.
For installation of the appliance at high altitude, up to
10,100 ft. (3,078 m) elevation above sea level, 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.
This appliance has been CSA certified for safe operation
up to an elevation of 10,200 ft (3,109 m) without any
modifications. Exception: For use with propane, the
appliance must be converted per the LP conversion
instructions.
ILCAUTION:
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).
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: 1 l"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
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" (19mm) 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 9 and Figure 10). The
appliance gas inlet connection is ½" (13mm) NPT.
• Use caution to avoid crimping the ¾" (19mm) flex
line when making bends. Suggested length of flex
line is 48" (1219mm); 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.
3. Always use pipe sealing compound or Teflon ® tape on
the pipe threads, and be careful not to apply excessive
pressure when tightening the fittings.
4. 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.
ILWARNING:
Do not use a flame of any kind to check for gas
leaks.
