It was previously 500mm D1 maximum length to tundish, but recent years was changed to 600mm.
The instructions and regulations description and drawings can be a bit confusing I must admit.
This was the original wording: "..The tundish shall be located not more than 500mm horizontally from any valve discharging to it" which taken together with the diagram makes me think it was installed correctly at the time.
The wording has now changed to: "..with no more than 600mm of pipe between the valve outlet and the tundish"
