YOUR WRONG
This rolling eyes thing is a bit odd - does it arise from some kind of clique?
Regarding the idea of a flue system, this is stretching a point beyond the bounds of credibility. The MI says this:
[code:1]
1. Installation Requirements
(sections 1.1 to 1.6 omitted for clarity)
1.7 Flue Systems
Horizontal
• The flue/terminal assembly supplied is suitable for a wall thickness of between 150 mm and 400 mm.
• A flue/terminal assembly suitable for a wall thickness of up to 600 mm is also available.
• Both the flue/terminal assemblies are telescopic and the minimum lengths (150 mm/6 in) are achieved by cutting.
• 1 m flue extensions are available.
• Under no circumstances should the total flue length exceed - 3.4 m, 30 - 70 models.
- 2.4 m, 80 models.
Vertical
1. Twin Tube system. 30 - 80 models.
Maximum actual length 7 m (7 extensions) Maximum equivalent resistance = 7 m
2. Vertical Concentric system.
30 - 70 models - Maximum actual length 3.4 m, equivalent resistance = 3.4 m. 80 models - Maximum actual length 2.4 m, equivalent resistance = 2.4 m.
Vertex
• The maximum primary flue length is 3.4 m.
• The maximum secondary flue length is:
30 model 5 m
40 model 5.5 m
50 & 60 models 6 m
Note: The flue lengths quoted refer to straight lengths. For the effects of bends and offsets see Section 2.2 'Install the Flue' or the appropriate flue instructions.

Note that this description relates only to what everyone, at all other times, regards as the flue system. Just in case there was another meaning on the forum, I've searched for the words "flue system", but found nothing of relevance, so you haven't given any information that shows I'm wrong.
So that all readers can understand why you think you're right, can you quote the section from the relevant legislation that prohibits replacement of the PCB by a non-registered engineer? Also, can you give me any idea why you disagree with CORGI's interpretation of the law in this context?
