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.

For installation of the appliance at high altitude, 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.

The field conversion kit for this series of Dual Fuel Ranges

is Thermador Model PALPKITHC. Obey all instructions in

this kit 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

appliance regulator must not exceed 14" (34.9

mb) water column.

WARNING

Gas line must not come in contact with any

components inside back cover 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 regulator

that has been permanently mounted within the range

body.

• Use 3/4" 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 8 and Figure 9). The

appliance gas inlet connection is 1/2" NPT. Use caution

to avoid crimping the 3/4" flex line when making bends.

Suggested length of flex line is 48"; 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.

• 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.

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 (3.5

kPa.).

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

(3.5 kPa.). When checking the manifold gas

pressure, the inlet pressure to the regulator

should be at least 6" W.C. (14.9 mb) for natural

gas or 11" W.C. (27.4 mb) for propane.

Do not attempt any adjustment of the pressure

regulator.

Natural Gas Requirements:

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: 11"min. to 14"max. water column

(27.4 mb to 34.9 mb)

Manifold Pressure: 10" water column (24.9 mb)
