If installed, remove the burner grates. 2. Remove burner cap. 3. Remove the burner base. A Large Dual Burner A. Burner cap B B. Burner base 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. A B A Medium Burner A. Burner cap C B B.

Apply masking tape to the end of a 7 mm nut driver to help hold the gas orifice spud in the nut driver while changing it. Insert nut driver into gas opening and press down onto the gas orifice spud and remove by turning the gas orifice spud counterclockwise and lifting out. Set gas orifice spud aside. 5. Replace with correct Natural gas orifice spud. See the "Natural Gas Orifice Spud/Hood Chart." Burner orifice spud A E D A. Access cap B. Gasket C. Gas pressure regulator C D. NAT position E. LP position 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). A. Size stamp or color Use the following chart to find the exact orifice spud placement. Remove choke from medium burner base.

Place LP gas orifice spuds in plastic parts bag for future use and keep with package containing literature. 7. Replace the burner base. 8. Replace burner cap. 9. Repeat steps 2 through 8 for the remaining burners. 13
