Checking for proper cooktop burner flame is very important.
The small inner cone should have a very distinct blue flame
V4" to V2" long. The outer cone is not as distinct as the inner
cone. Natural gas flames do not have yellow tips.
IMPORTANT: You may have to adjust the "LO" setting for each
cooktop burner.
