Currently my gas pipe runs along the outside wall, from the external meter
to where it enters the kitchen (about a 4m run). The pipe is earth-bonded
inside the kitchen near where it passes through the wall.
I'm thinking of installing a (natural gas) CH boiler in the kitchen (the
house has an old propane cylinder based system).
The new boiler's position means that its gas supply would need to be 'Teed'
off the external pipe about half way along.
As I understand them, the regs say that earth bonding to the gas pipe must
be where the pipe enters the house (for an external meter) and before any
So, my question is will I have to redo the earth bonding - replacing a
perfectly good one for one that connects to just before the new 'T' in the
If the answer is 'yes', this means the connection will need to be on the
outside of the pipe (before the T); I don't like the idea unless proper
weather proof connection boxes are available - are they?
