An open flame is not always necessary to ignite a gas. A hot surface - like a heating element or warm machine - will do for chemicals with more than high hazard.
See Autoignition temperature and flash point of different hydrocarbons and Flash Point - Fuels for measured values of flash point.
The Flash Point is not the same as the Auto-Ignition Temperature. The Auto-Ignition Temperature is the minimum temperature required to ignite a gas or vapor in air without a spark or flame present.
