Rob, I don't understand your message.
Your quoted dictionary passage confirms what I said.
Flash point is the temperature at which the fuel produces flammable vapors.
These vapors can then be ignited by something that is at, or above, the
Ignition temperature (much higher than the Flash point temperature), such as
a spark or flame.
