Natural gas connection
To connect the gas
1. Make sure the gas supply is turned off at the manual
shut-off valve before connecting the appliance.
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 left rear of the
appliance. 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" (1,219 mm); however, please check
local codes for your area's requirements before
installation.
3. 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.
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.
Propane (LP) gas connection
Rangetops are shipped by the factory to operate on
natural gas. They must be converted for use with propane.
Verify the type of gas being used at the installation site
matches the type of gas used by the appliance.
If the location site requires conversion from natural gas to
propane (LP), contact the dealer where the unit was
purchased or contact Thermador
®
to purchase a
conversion kit. Obey all instructions in this kit for correct
conversion of the gas regulator and settings for the gas
valves. Field conversion must be done by qualified service
personnel only.
9 WARNING
If a gas conversion kit is used, the kit shall be installed
by a qualified service personnel in accordance with
the manufacturer’s instructions and all applicable
codes and requirements of the authority having
jurisdiction. If the information in the instructions is not
followed exactly, a fire, explosion or production of
carbon monoxide may result causing property
damage, personal injury or loss of life. The qualified
service personnel is responsible for the proper
installation of the kit. The installation is not proper and
complete until the operation of the converted
appliance is checked as specified in the
manufacturer’s instructions supplied with the kit.
9 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).
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 7.0" (17.4
mb) W.C. for natural gas or 11.0" (27.4 mb) for
propane.
DO NOT attempt any adjustment of the pressure
regulator.
9 CAUTION
Save the orifices removed from the appliance for
future use. 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 a 14'' water column
(34.9 mb).
