Gas Requirements and Hookup, Hook UP

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 instruc- tions in PLPKIT for correct conversion of the gas regulator and settings for the gas valves.

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 appli- ance regulator must not exceed 14" (34.9 mb) water column.

This appliance has been CSA certified for safe opera- tion up to an elevation of 10,200 ft. without any modi- fications. Exception: For use with propane, the appli- ance must be converted per the LP conversion in- structions.

Natural Gas Requirements:

Inlet Connection: 3/4" NPT external 1/2" NPT internal (Minimum 3/4" diam. flex line.)

Supply Pressure: 6" min. to 14" max. water col- umn.

(14.9 to 34.9 mb)

Manifold Pressure: 5" water column (12.5 mb)

Propane Gas Requirements:

Inlet Connection: 3/4" NPT external 1/2" NPT internal (Minimum 3/4" diam. flex line.)

Supply Pressure: 11" min. to 14" max. water col- umn.

(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. Run gas line in channel in back of range.

HOOK UP

•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 regu- lator that has been permanently mounted within the range body.

•Use 3/4" flex line to connect between the gas supply and the appliance manifold pipe, which exits the upper rear of the appliance. The appli- ance manifold pipe connection has a 3/4" NPT external thread and a 1/2" NPT internal thread. (See Photo A.) Use caution to avoid crimping the 3/4" flex line when making bends.

•The gas supply connections shall be made by a competent technician and in accordance with local codes or ordinances. In the absence of a local code, the installation must conform to the National Fuel Gas Code ANSI Z223.1/NFPA54- current issue.

•Always use pipe sealing compound or Teflon® tape on the pipe threads, and be careful not to apply excessive pressure when tightening the fittings.

•Leak testing of the appliance shall be in accor- dance 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.

•Do not use a flame of any kind to check for gas leaks.
