Thermador PCG305W Installation Instructions Manual page 14

High Altitude
This appliance has been tested for operation up to an
altitude of 10,100 ft (3,078 m) elevation above sea level.
If desired, for altitudes above 2,000 feet (610 m) elevation
above sea level, adjustments can be made with a High
Altitude Kit. If flame performance is satisfactory,
adjustment will not be required. It is required that a
Certified Professional make the high altitude adjustments
during installation.
Gas Requirements
Natural Gas Requirements:
• Inlet Connection: 1/2'' NPT internal (Minimum 3/4''
dia. flex line)
• Supply Pressure: 6'' min. to 14'' max. water column
(14.9 to 34.9 mb)
• Manifold Pressure: 5'' water column (12.5 mb)
Propane Gas Requirements:
• Inlet Connection: 1/2'' NPT internal (Minimum 3/4''
dia. flex line)
• Supply Pressure: 11'' min. to 14" max. water column
(27.4 mb to 34.9 mb)
• Manifold Pressure: 10'' water column (24.9 mb)
Rangetops are shipped by the factory to operate on
natural gas. They must be converted for use with propane.
Verify the type of gas being used at the installation site
matches the type of gas used by the appliance.
If the location site requires conversion from natural gas to
propane (LP), contact the dealer where the unit was
purchased or contact Thermador
conversion kit. Obey all instructions in this kit for correct
conversion of the gas regulator and settings for the gas

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.
CAUTION
Save the orifices removed from the appliance for
future use. 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 regulator supplied with the appliance. The
pressure of the gas supplied to the appliance
regulator must not exceed a 14'' water column
(34.9 mb).
