where do differential gas pressure like 500mbar (half a bar) come into the equation?
I don't see where you other figs come from either.
My guess is that the guy did just turn the gas off, (that's what he said) so the pressure in the pipe would go to about atmospheric + maybe a few mbar, and then only weather variations would be the driving force.
We're talking 6 weeks, not 6 months, too.
nam - 100% gas burns in air perfectly well!
Still not convinced.
