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)
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.
• 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.
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.
