Natural Gas Conversion 1. Turn the manual shut-off valve to the closed position. B A C A. To cooktop B. Shut-off valve (closed position) C. Gas supply line 2. Unplug cooktop or disconnect power. To Convert Gas Pressure Regulator 1. Remove the gas pressure regulator cap by using a large flat-blade screwdriver, turning the regulator cap counterclockwise. When the cap is removed, do not lose the metal seal. 2. Remove spring retainer from the cap by turning the spring retainer counterclockwise. Locate the "LP" and "NAT" position on the spring retainer. Turn over the spring retainer so the "NAT" arrow is pointing toward the cap. A LP NAT B C LP D LP NAT LP NAT E NAT A. Regulator cap B. Metal seal C. Gas pressure regulator D. Spring retainer in LP position E. Spring retainer in NAT position 3. Tighten the gas pressure regulator cap by using a large flat-blade screwdriver, turning the regulator cap clockwise. 4. 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: 5" (12.7 cm) WCP Maximum pressure: 14" (35.6 cm) WCP Gas Supply Pressure Testing Gas supply pressure for testing regulator must be at least 1" (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 (14" [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 (14" [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. A Burner B A. Burner cap B. Screws C C. Burner base 4. Apply masking tape to the end of a 1/4" (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 B A. Size stamp B. Fuel type stamp (L for Propane or N for Natural gas) 16
