Checking for proper cooktop burner flame is very important.
The small inner cone should have a very distinct blue flame
¼" to ½" long. The outer cone is not as distinct as the inner
cone. LP gas flames have a slightly yellow tip.
IMPORTANT: You may have to adjust the “LO” setting for
each cooktop burner.
