Step 6: Electrical Requirements, Connection & Grounding - Thermador Professional PRO-HARMONY PRG30 Manuel D'installation

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, located at the lower right
portion of the range. (See Figure 9.) The appliance inlet
pipe 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
force 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 (3.5kPa.).
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" (14.9 mb) W.C. for natural gas or 11.0" (27.4
mb) for propane.
Do not attempt any adjustment of the pressure
regulator.
