I'm recreating the original constructional hearth ready for new fireplace
and hearth...

And while I'm about it, how do I get the gas from under the (suspended)
floor to the back of the hearth for an inset living flame whilst keeping it
hidden from view?
Knock a brick corner of the side of the builders opening or fabricate a void
in the constructional hearth when I pour the concrete?

And is this to be copper or is it common to do some flexi something?

Yes Corgi registered fitter will do final connection.

TIA
