Step 6: Electrical Requirements, Connection & Grounding - Thermador PROFESSIONAL PRO HARMONY Serie Instructions D'installation

• The range is supplied with its own pressure
regulator that has been permanently mounted
within the range body.
2. Use a ¾'' (19 mm) flex line to connect between the gas
supply and the appliance gas inlet. The gas supply line
connection is located at the lower right portion of all
range models (see Figure 9). The appliance gas inlet
connection is ½'' (12.7 mm) NPT.
• Use caution to avoid crimping the ¾'' (19 mm) flex
line when making bends. Suggested length of flex
line is 48" (1219 mm); however, please check local
codes for your area's requirements before
installation.
3. Use pipe sealing compound or Teflon
pipe threads. DO NOT apply sealing compound or tape
to flare fittings. Take care not to apply excessive
pressure when tightening the fittings.

WARNING
An improper 120 VAC power supply will cause
malfunction, damage to this appliance, and possibly
create a condition of shock hazard.
Before installing, turn power OFF at the service panel.
Lock service panel to prevent power from being turned
ON accidentally.
For these gas range models, a neutral supply wire must be
provided from the power source (breaker) because critical
range components, including the surface burner spark
reignition modules, require 120 VAC to operate safely and
properly.
