Thermador P24WK - Manual (Page 11)

Step 4: Gas Requirements and Hookup
Natural Gas Requirements:
Inlet Connection: 3/4" N.P.T. (Minimum 3/4"
dia. flex line.)
Supply Pressure: 6" to 14" water column
Manifold Pressure: 5" water column
Propane Gas Requirements:
Inlet Connection: 3/4" N.P.T. (Minimum 3/4"
dia. flex line.)
Supply Pressure: 11" to 14" water column
Manifold Pressure: 10" water column
Cooktops are shipped by the factory to operate on
natural gas. 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 conver-
sion from one type of gas to another, contact the
dealer where the unit was purchased or contact
Thermador (800/735-4328). The field conversion
kit for all Professional cooktops (PC series) is
Thermador Model PLPKIT. Obey all instructions in
PLPKIT for correct conversion of the gas regulator
and settings for the gas valves. Field conversion
must be done by qualified service personnel only.
HOOK UP
• A manual gas shut-off valve must be installed
external to the appliance, in a location acces-
sible 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 gas supply connections should 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.
FOLLOWING NOT APPLICABLE TO PC304
• Install the gas pressure regulator (supplied) to
the manifold pipe. Ensure that the appliance
pressure regulator is set to 5" W.C. for natural
gas and 10" W.C. for propane gas, and that the
arrow points in the direction of the gas flow
towards the appliance. Connect the gas supply
line to the unit pressure regulator using a
3/4" flex gas line between the manual gas shut-
off valve and pressure regulator. (See Fig. 9.)
• Always use pipe dope or Teflon ® tape on the
pipe threads, and be careful not to apply exces-
sive 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.
• Do not use a flame of any kind to check
for gas leaks.
• All installer-supplied parts must conform to all
applicable codes.
