- Remove the hexagon shaped cap from the regulator making sure not to dislodge the gasket on the cap or the spring inside the regulator.
- Grasp the plastic button stem firmly and pull it forcefully from the metal cap. The stem snaps snugly into an indent in the cap and may require a strong pull to remove. (Hint: it may be helpful to gently “rock” the plastic stem while pulling it from the metal cap.)
A Spring B Plastic button stem C Gasket - After removing the stem from the cap, rotate the stem 180° so the button end of the stem is away from the cap and the letters “LP” on the stem are upside down when the cap is set flat on its head. Snap the stem back in place in this position inserting it into the indent in the metal cap.The stem should snap into place.
- Important: Attach the metallic sticker (included with this conversion kit) to the bottom of the appliance as shown, placing it near the appliance data plate (shows model number and information about the appliance). This sticker provides notice that the appliance has been converted for use with LP gas.
- Remove all burner grates, burner caps and burner bases.
- To replace the nozzles, use a 7 mm socket wrench. See table. It is important to make sure that the nozzles do not become detached during removal or fastening. They must be properly tightened to ensure that there are no leaks.
With these burners, there is no need to adjust the primary air. - Fasten the nozzles and attach the burner caps to the corresponding burners. Put the burner grates in place on the corresponding burners.
- Attach the sticker indicating the new gas type close to the rating label.
Save the nozzles removed from the appliance for future use. If you change the type of gas back to Natural Gas at a later point, remove the sticker. - Turn the control knobs to the lowest setting.
- Remove the control knobs from the gas valves and remove the white ring that is underneath. A flexible black rubber sealing ring will be visible. Below the left upper position of that seal, there is a visible black Star T10 screw, partly hidden by the seal. Press the rubber seal aside a bit to meet the screw with a long thin T10 screwdriver. The dual-flame burner has 2 setting screws.
Never remove the sealing ring. Sealing rings prevent liquids and dirt from finding their way into the appliance and impairing its ability to function properly. - See the following chart for the setting of the gas valve’s setting screws (M):
A: LP Gas- The gas valve’s setting screws must be tightened properly.
B: Natural Gas- The gas valve’s setting screws must finish flush with the fitting.
Make sure the flame does not go out and there are no flashbacks when you turn the control knob between the highest and lowest setting.
Never remove the valve stem. In the event of damage, the gas valve must be completely replaced.
