5. 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 4. 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 the 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." Use the following chart to find the exact orifice spud placement.

Tighten the gas pressure regulator cap by using a large flatblade screwdriver, turning the regulator cap clockwise. 7. 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" (35.6 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 range 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 range 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 from Propane to Natural Gas 1. If the burner grates are installed, remove them. 2. Remove burner cap. 3. Remove the burner base by first removing (2) T-20 screws.

Tighten screws only until burner is snug to cooktop, do not over-tighten. 8. Replace burner cap. 9. Repeat steps 2 through 8 for the remaining burners. Adjusting Simmer Low Setting on Surface Burners for Natural Gas 1. Unplug range or disconnect power. 2. Using the square bit screwdriver, remove the surface burner control knobs and bezels (Oven control knobs and griddle control knobs do not have to be removed). 18
