To Convert Surface Burners 1. Remove Natural gas orifice hoods. Locate the LP gas orifice hoods from the package attached to the outer plenum area of this appliance. 2. To convert from Natural gas to LP gas, apply a ½" open-end wrench to hex section of orifice hood. Turn counterclockwise to remove. 3. Replace with correct color-coded orifice hoods (supplied). See the "LP Gas Orifice Hood Chart." Turn clockwise to install. Screw down the orifice hood so that the outer end of the orifice hood is from the face of the mounting spud. See the following illustration. A C Turn counterclockwise to remove Turn clockwise to tighten B A. ½" open-end wrench B. Orifice hood C.

Place Natural gas orifice in plastic parts bag for future use and keep with package containing literature. 5. Repeat for the remaining burners. Complete Installation 1. Refer to the "Make Gas Connection" section for properly connecting the cooktop to the gas supply. 2. Refer to the "Burner Ignition" 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 cooktop "low" burner flame should be a steady blue flame approximately ¼" (0.64 cm) high. 3. Refer to the "Complete Installation" section of this manual to complete this procedure. Natural Gas Conversion 1. Turn manual shutoff valve to the closed position. B A C A. To cooktop B.

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 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). 13
