4. Provide an Adequate Gas Supply

This cooktop is designed to operate on natural gas at 4"
(10.2 cm) of manifold pressure only.
A pressure regulator is connected in series with the
manifold on the cooktop and must remain in series with
the supply line.
For proper operation, the maximum inlet pressure to
the regulator must be no more than 14" (35.6 cm) of
water column (W.C.) pressure.
For checking the regulator, the inlet pressure must be at
least 1" (2.5 cm) (or 2.5 kPa) greater than the regulator
manifold pressure setting. The regulator is set for 4"
(10.2 cm) of manifold pressure, the inlet pressure must
be at least 5" (12.7 cm).
The gas supply line to the cooktop should be ½" (1.3
cm) or ¾" (7.9 cm) pipe.

5. LP/Propane Gas Conversion

This appliance can be used with Natural gas or LP/
Propane gas. It is shipped from the factory for use with
natural gas.
If you wish to convert your cooktop for use with LP/
Propane gas, use the supplied fixed orifices in the
package containing the installation Instructions Manual,
Follow the installation instructions packaged with the
The conversion must be performed by a qualified service
technician in accordance with the manufacturer's
instructions and all local codes and requirements of
the authority having jurisdiction. Failure to follow
instructions could result in serious injury or property
damage. The qualified agency performing this work
assumes responsibility for the conversion.
Failure to make the appropriate conversion
can result in personal injury and property damage.
Remove all packing material and literature
from cooktop before connecting gas and electrical
supply to cooktop.

6. Install Pressure Regulator

Install the pressure regulator with the arrow on the
regulator pointing up toward the unit in a position
where you can reach the access cap.
FIRE HAZARD. Do not make the
connection too tight. The regulator is die cast.
Overtightening may crack the regulator resulting in a gas
leak and possible fire or explosion.
Assemble the flexible connector from the gas supply pipe
to the pressure regulator in order: 1- manual shutoff
valve, 2- ½" nipple, 3- ½" flare union adapter, 4- flexible
connector, 5- ½" flare union adapter, 6- ½" nipple,
pressure regulator.
Flexible Connector
All connections must be wrench-tightened
Use pipe-joint compound made for use with Natural and
LP/Propane gas to seal all gas connections. If flexible
connectors are used, be certain connectors are not
The supply line should be equipped with an approved
shutoff valve. This valve should be located in the same
room as the cooktop and should be in a location that
allows ease of opening and closing. Do not block access
to the shutoff valve. The valve is for turning on or
shutting off gas to the appliance.
To Appliance
Shutoff Valve
Open the shutoff valve in the gas supply line. Wait a few
minutes for gas to move through the gas line.
Check for leaks. Leak testing of the appliance shall be
conducted according to the manufacturer's instructions.
After connecting the cooktop to the gas supply, check
the system for leaks with a manometer. If a manometer
is not available, turn on the gas supply and use a liquid
leak detector (or soap and water) at all joints and
connections to check for leaks.
Do not use a flame to check for leaks from
gas connections. Checking for leaks with a flame may
result in a fire or explosion.
Tighten all connections if necessary to prevent gas
leakage in the cooktop or supply line.
