Step 7: Electrical Requirements, Connection & Grounding - Thermador PROFESSIONAL PRO GRAND Installation Instructions Manual

• Suggested length of flex line is 48" (1219 mm);
however, please check local codes for your area's
requirements before installation.
WARNING
Gas line must not come in contact with any components
inside back cover of range.
4. Use a pipe sealing compound or Teflon
pipe threads. Do not apply sealing compound or tape
to flare fittings. Be careful not to apply excessive
pressure when tightening the fittings.
5. 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.
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.
Installer is responsible for ensuring that the installation, gas
connections, and grounding comply with all applicable
codes.
CAUTION
Do not remove the back cover of the range. It is for an
authorized servicer access only.
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.).

Before installing, turn power OFF at the service panel. Lock
service panel to prevent power from being turned on
accidentally.
A neutral supply wire must be provided from the power
source (breaker panel) because critical range components,
including the surface burner spark reignition modules,
require 120 VAC to operate safely and properly.
WARNING
An improper 120 VAC power supply will cause
malfunction, damage to this appliance, and possibly
create a condition of shock hazard.
If the correct power supply circuit is not provided, it is the
responsibility and obligation of the installer and user to
have proper power supply connected. This must be
accomplished in accordance with all applicable local codes
and ordinances by a qualified electrician. In the absence of
local codes and ordinances, the power supply connection
shall be in accordance with the National Electrical Code.
Observe all governing codes and ordinances when
grounding. In the absence of these codes or ordinances
observe National Electrical Code ANSI/NFPA No. 70
current issue.
Electric wiring diagrams and schematics are attached
behind the door trim of the range, for access by a qualified
service technician (see Figure 30 on page 24).
