Installation Instruction

Natural Gas Conversion
1. Turn the manual shut-off valve to the closed position.
2. Unplug cooktop or disconnect power.
To Convert Gas Pressure Regulator
1. Remove the access cap by using a wrench, turning the
access cap counterclockwise.
2. Remove spring retainer from the cap by pushing against the
at side of the spring retainer. Look at the spring retainer to
locate the “LP” or “NAT” position. Turn over the spring
retainer so the “NAT” is showing on the bottom. Snap the
spring retainer back into the cap. Reinstall the cap onto the
regulator.
3. Test the gas pressure regulator and gas supply line.
The regulator must be checked at a minimum 2.5 cm water
column above the set pressure. The inlet pressure tothe
regulator should be as follows for operation and checking
the regulator setting:
Propane Gas:
Minimum pressure: 15.2 cm WCP
Maximum pressure: 35.6 cm WCP
Gas Supply Pressure Testing
Gas supply pressure for testing regulator must be at least
2.5 cm water column pressure above the manifold pressure
shown on the model/serial/rating plate.
Line pressure testing above 1/2 psi (3.5 kPa) gauge
(35.6cm WCP)
The cooktop and its individual shut-off valve must be
disconnected from the gas supply piping system during
anypressure testing of that system at test pressures in
excess of 1/2 psi (3.5 kPa).
Line pressure testing at 1/2 psi (3.5 kPa) gauge
(35.6cmWCP) or lower
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
pressures equal to or less than 1/2 psi (3.5 kPa).
To Convert Surface Burners
1. If installed, remove the burner grates.
2. Remove burner cap.
3. Remove the burner base.

4. Apply masking tape to the end of a 7 mm nut driver to help
hold the gas orice spud in the nut driver while changing it.
Insert nut driver into gas opening and press down onto the
gas orice spud and remove by turning the gas orice spud
counterclockwise and lifting out. Set gas orice spud aside.
5. Replace with correct Natural gas orice spud. See the
“Natural Gas Orice Spud/Hood Chart.”
Use the following chart to nd the exact orice spud
placement.
Remove choke from medium burner base.
