Thermador PROFESSIONAL PRO GRAND PRD36 Manual De Instalación página 17

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.
The range is supplied with its own pressure regulator that
has been permanently mounted inside the range.
• Make sure the gas supply is turned off at the manual
shut-off valve before connecting the appliance.
• Use 3/4" (19mm) flex line to connect between the gas
supply and the appliance inlet pipe, which exits the
rear, lower right of the appliance. The appliance pipe
connection has a 3/4" (19mm) NPT external thread and
a 1/2" (13mm) NPT internal thread (see Figure 10 on
page 14).
• Use caution to avoid crimping the 3/4" (19mm) flex
line when making bends.
• Suggested length of the flex line is 48" (1219mm);
however, check local codes for requirements
before installation.
• Use pipe sealing compound or Teflon
pipe threads, and be careful not to apply excessive
force when tightening the fittings.
Leak testing of the appliance shall be in accordance with
the following instructions.
•
•
Installer is responsible for ensuring that the installation, gas
connections, and grounding comply with all applicable
codes.

tape on the
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. (14.9
mb) for natural gas or 11.0" W.C. (27.4 mb) for propane.
Do not attempt any adjustment of the pressure regulator.
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
(3.5kPa.).
