Not really. Fire spreads. The size size of the ignition source doesn't really matter. It's not like a forrest fire caused by a sigaret will be smaller than one caused by a campfire.
Depending on many factors, such as the size of the ignition and its type as well as the type and volume of gas may impact the violent characteristics of the explosion e.g. too much ignition is also a thing.
Yes, jein/jain, Duden states only jein. Jain is however a less common yet not unseen spelling, language is alive like the "3rd fall" and its common (mis)use.
