Thermador PCG48 Gas Requirements and Hookup, Natural Gas Requirements, Propane Gas Requirements

Step 4: Gas Requirements and Hookup

Cooktops 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/job site requires conversion from natural gas to propane (LP), contact the dealer where the unit was purchased or contact Thermador. The field conversion kit for the Professional Cooktops in this series is Thermador Model PALPKITHC. 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.

Natural Gas Requirements:

Inlet Connection: 1/2” NPT (min. 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 (min. 3/4” dia. flex line)

Supply Pressure: 11” min. to 14” max. water column (27.4 mb to 34.9 mb)

Manifold Pressure: 10” water column (24.9 mb)

•The installer should inform the consumer of the location of the gas shut-off valve. Make sure all users know where and how to shut off the gas supply to the cooktop.

•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.

•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 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.

•All installer-supplied parts must conform to applicable codes.

WARNING

If a gas conversion kit is used, the kit shall be installed by a qualified service agency 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 agency 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.

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.

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 a 14” water column (34.9 mb).

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 6.0" W.C. for natural gas or 11.0" for propane.

Do not attempt any adjustment of the pressure regulator.
