STEP 4: Gas Requirements & Hookup
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 regu-
lator supplied with the appliance. The pressure of
the gas supplied to the appliance regulator must not
exceed 14" water column.
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.
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 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 conversion
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 Profes-
sional cooktops (PSC series) is Thermador Model
CTLPKIT. Field conversion must be done by qualified
service personal only.
ATTENTION:
L’appariel doit etre isole du systeme de tuyauterie de
la fourniture de gaz en ferment la soupape a -main
d’arret individual pendant ltessai du systeme de
tuyauterie de la fourniture de gaz aux pressions,
d’epreuve egale a ou au moins que 1/2 psig (3.5 kPa.).
L’appareil et sa soupape d’arret individual doivent
etre deconnectes du systeme de tuyauterie de la
fourniture de gaz pendant l’essai du systeme aux
pressions d’epreuve en plus de 1/2 psig (3.5 kPa).
En exarninant la pression de gaz du collecteur, la
pression d’ en tre e au regulateur doit e tre au
moins de 6.0"
W.C. pour le gaz naturel ou 11.0" pour le propane.
Ne pas tenter aucun reglage du regulateur de pression.
ATTENTION:
En branchant l’appareil au gaz de propane, soyez
certain que le réservoir de gaz du propane est équipé
avec son regulateur de haute pression á lui-méme en
addition du régulateur de pression fourni avec
l’appareil. La pression du gaz fourni avec l’appareil. La
pression du gaz fourni au régulateur de l’appareil ne
doit pas excéder une colonne d’eau de 14".
HOOK UP
•
A manual gas shut-off valve must be installed exter-
nal to the appliance, in an accessible location 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, Current Issue.
•
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 excessive
pressure when tightening the fittings.
•
Turn on gas and check supply line connections for
leaks using a soap solution. Do not use a flame of
any sort to check for leaks.
•
All installer-supplied parts must conform to
Local Codes.
