For what it's worth....
Vera has a remote vent valve as well. Attached to the outlet of said valve is an air ejector. Something like this: https://www.mcmaster.com/#air-ejectors/=1a9bkx0. Anywho, the idea is to mix the (presumably explosive) mixture coming out of the gun with ambient air thus leaning out the mixture so that you don't have to worry about sources of ignition as anything coming out of the gun is no longer flamable.
On that note - especially since you're worried about mixing - Vera has another ejector (2 of them, actually) inside the combustion chamber. The inlet of the ejector is in one location of the chamber while the outlet is at another. The point being that the very act of injecting fuel or air (both get injected through the ejector) actively mixes the contents of the chamber.
