General Information
Gas Requirements (continued)
Pressure Regulator:
• The regulator supplied with the RDGSU
cooktops must be installed before any gas
connections are made. It is preset for use
with natural gas. This must be converted
for use with LP/Propane gas.
• Manifold pressure should be checked with
a manometer. Natural gas requires 5.0 "
WCP (water column pressure) and LP/
Propane requires 10.0" WCP. Incoming
line pressure upstream for the regulator
must be 1" WCP or higher than the
manifold pressure in order to check the
regulator.
• The regulator used on this cooktop can
withstand a maximum input pressure of
1/2 PSI (14" WCP). If the line pressure
is in excess of that amount a step-down
regulator will be required.
• The manual shut-off valve and pressure
regulator of these cooktops must be
disconnected from the gas supply piping
system during any pressure testing of that
system at pressures in excess of 1/2PSI
(3.45kPa).
• The cooktop 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 pressure equal to or less
than 1/2 PSI (3.45kPa).
IMPORTANT: NEVER reuse old connectors
when installing this cooktop.

Rigid Connections:
• Incoming gas is brought from an intake
pipe at the rear of the unit to the pressure
regulator; then to the manifold pipe for
distribution. The intake pipe and shut-off
valve are not supplied. The intake pipe and
the shut-off valve should be connected to
the regulator to complete the connection.
In Massachusetts: This appliance must be
installed with a 36" (3 foot) long flexible gas
line.
• The alignment of the valves should be
checked after connecting the cooktop to
the gas supply to be sure the manifold pipe
has not been moved. A misalignment may
cause the valve knob stem to rub on the
control panel, resulting ina gas leak at the
valve.
• Installer-supplied intake pipes should be
checked visually for any foreign matter
before installing in a service line.
Proper Lighting and Shutdown Instructions
To ignite electric igniters on the surface
burners :
1. Turn the knob counterclockwise to any
position.
2. Upon ignition of the surface burner, turn
the knob to the desired position (HI, MED,
or LOW).
3. To shutdown the burner, turn knob
clockwise to the OFF position.
In case of failure, shut the gas OFF using the
installer supplied manual shut-off valve.
