Gas heavier than air might result in stratification if there is nothing to distrub the gas and / or air. Bottom half of the room the match goes out. Upper half of the room the match burns away. Anyway near the boundary layer. Good bye room.
You are worrying about nothing, as I said before two battens, something to protect the pipe from damage and cover the channel and forget about it, if its not leaking gas when you cover why would it suddenly develop a dangerous leak ?

Yes, but natural Gas is lighter than air and in any case at some point in the room the mixture will be between the LEL and UEL and thus very flammable!
Those who were talking about space between battens seem to have forgotten that if there was a gas leak then as the gas comes out and mixes with the air there will be a point where the mix will be between the LEL and HEL and thus flammable!

I wondered how long it would be before the discussion degenerates into what makes someone competent to work on gas / DIY, I think we will be getting there any moment.
As far as I can tell the OP is working with an existing pipe. Tony is off on one of his tangents and Bernard is trying to free think his way around pretty simple and clear cut rules.
