Gas bottles & bonding!

[sparks72]

Been to a customer on a farm, they have oil heating & two calor gas bottles outside feeding
the gas hob in copper, can't see anything in the regs regarding earth bonding gas bottles or am I not looking hard enough

Thanks.

I thought gas bottles were connected via rubber hoses?

If not, wont hurt bonding where it enters the building as per norm.

Thank's Jason.
The bottles have an isolator valve on the outside wall attached to them then
15mm copper pipe from the isolator, through the wall to the gas hob.
