Can anyone quote chapter and verse on the requirements to bond the gas
supply to earth.
I recently removed a Baxi back boiler and demolished the false chimney
breast that hid it. The was a green earth wire connected to the final
15 mm copper pipe that came out of the 3/4 inch iron pipe that runs
under the floor beneath where the boiler was and parallel to the
skirting (in the screed).
Presumably I need to reconnect this somewhere but is it OK to extend
it outside and into the garage, then attach it to the outlet of the gas
meter ?, or does it need to be connected to a copper pipe ?.
All new houses seem to have an earth strap coming out the outside wall
and connected to the copper gas pipe where it enters the wall.
