5.Complete installation sections D through E, Pages 5-7. Checking for proper cooktop burner and oven flame is very important.

The small inner cone should have a very distinct blue flame 1/4" to 1/2" long. The outer cone is not as distinct as the inner cone. L.P. gas flames may have a slightly yellow tip.

A brass orifice spud is located in the center of each burner throat about 2" below the cooktop. Apply masking tape to the end of a 5/16" nut driver to fit snugly over the orifice spud. Press driver down onto the spud of the left front burner and remove by turning spud counter-clockwise and lifting it out. Replace the Natural gas spud with the appropriate L.P. gas spud shown in the table.

Continue to replace the remaining orifice spuds, one at a time. Place the Natural gas spuds on the spud card on the back of the range for future use. Replace burners, screws and caps.
