To Convert Grill Burner (on some models)
1.Remove grill grate, wave plate, flame spreader and burner assembly. See “Install Grill Grease Trays” section for removal instructions. Set parts aside.
2.Use a ½"

A. Grill orifice hood location
3.Turn LP gas orifice hood down tightly onto orifice base.
4.Place Natural gas orifice hoods in plastic parts bag for future use and keep with package containing literature.
5.Open shutoff valve in the gas supply line. The valve is open when the handle is parallel to the gas pipe.
REMEMBER: Once you have completed converting the grill, test the cooktop for leaks by brushing on an approved noncorrosive
6.Plug in cooktop or reconnect power.
Complete Installation
1.Refer to the “Make Gas Connection” section for properly connecting the cooktop to the gas supply.
2.Refer to the “Electronic Ignition System” section for proper burner ignition, operation, and burner flame adjustments.
IMPORTANT: You may have to adjust the “LO” setting for each cooktop burner.
Checking for proper cooktop burner flame is very important. The small inner cone should have a very distinct blue flame ¼" (0.64 cm) to ½" (1.3 cm) long. The outer cone is not as distinct as the inner cone. LP gas flames have a slightly yellow tip.
3.Refer to “Complete Installation” in the “Installation Instructions” section of this manual to complete this procedure.

1.Turn manual shutoff 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 flat 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 1" (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:
Natural Gas:
Minimum pressure: 6" (15.2 cm) WCP
Maximum pressure: 14" (35.5 cm) WCP
Gas Supply Pressure Testing
Gas supply pressure for testing regulator must be at least 1" water column pressure above the manifold pressure shown on the model/serial rating plate.
Line pressure testing above ½ psi gauge (14" WCP)
The cooktop and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of ½ psi (3.5 kPa).
Line pressure testing at ½ psi gauge (14" WCP) or lower
The cooktop must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than ½ psi (3.5 kPa).
To Convert Surface Burners
1.If installed, remove the burner grates.
2.Remove burner cap.
3.Remove the burner head.
NOTE: A ⁷⁄₈" socket must be used to remove the burner head of the large dual burners.
