After the regulator has been converted the top burner bases require conversion:

1)To expose the burner base, remove the porcelain cap and aluminum flame spreader.

2)Find the 7 mm oriface removal tool, included with the kit. (The end of the tool is flattened to accept a standard slot screw driver to make the oriface removal easier) Insert the tool inside the burner base and turn the orifice out of the jet holder, COUNTER-CLOCKWISE. (Put the orifice in a safe place, in case you need to reconvert later.)

3)Find the appropriately numbered orifice for the burner.

4)Use the tool to screw the burner orifice into place in a clockwise motion.

Before proceeding with each step, check the orifice with a flashlight to make sure there is no debris blocking the opening of the orifice. Follow the same procedure for the the rest of the burners.

After converting the burners with new orifaces the burner valves need to be adjusted. The gas supply should be turned on for this step:

1)Remove the control knob only, the valve cover need not be removed.

2)Turn the burner on and set to low.

3)The flame size will have to be adjusted up or down depending on the gas you are converting to.

To adjust flame size insert the small slot screw driver (included with this kit) inside the valve stem (see valve illustration)

4)Turn the screw driver clock wise to decrease, counter clock wise to increase flame.

Adjust the flame size just so the flame curls around the porcelain cap. If the igniter starts or you have problems with the flame going out you have adjusted to low.

When converting to LP (liquid propane) the flame will have to be adjusted down

When converting to natural gas the flame will have to be adsjusted up.
