Ive allways avoided fires when I can but for a CP12 you are required to do exactly the same checks and tests as when installing. For example you may perform a spillage test which passes fine but without removing the fire how can you tell the flue is clear? If there is no liner how can you tell that no mortar is missing from the brickwork? or that any gas pipe inside the builders entrance is taped up?
In reality as soon as you do any work on a gas appliance you are then from that point responsible for it, so a lack of identification should mean you disconnect it and make it safe until it can be identified and tests performed on it to the MI.
