What needs to be clarified
The examination would compare the installed item, agreed replacement and documents, separating a supported mismatch from assumptions about its consequences.
Materials to prepare
- Design documents, equipment manual and agreed replacement list.
- Repair record, supply documents and photographs of accessible markings.
- Replacement correspondence and inspection records from the specialist organisation.
What to compare
- Link each designation to its particular component and document.
- Compare the items’ functions and specifications against technical documentation.
- Identify questions that the available material cannot resolve.
Possible outcome of the analysis
A possible result is an opinion on consistency between installation and records, listing additional checks needed.
Limits of the conclusions
The examination does not include independently starting gas equipment, interfering with the network or authorising operation.
