I have discussed this query out with Gas Safe technical and they agree that the document is not that specific. They tend to agree that "turning off" a gas appliances/installation requires turning off the gas valve. The interpretation of "turning Off" will be put forward for discussion, at the next review of IUSP which will be sitting sortly. So watch this space.
so if an appliance has the potential to be dangerous should you not ideally cap it then?
