I assume you meant the piece of metal support that ensures the centre exhaust tube stays central and prevents it from not conecting correctly on the boiler thus allowing cross cirulation of exhaust and intake ?
Thats the only thing the corgi helpline told me to observe.
No, you've missed it, so we don't know whether your flue is correct or not. Flues have Flue Restrictor(s) which you have to get right so the gas to air mixture is right, ensuring the boiler doesn't produce carbon monoxide. If there's a leak somewhere, the CO gets into the room and the owner (
and the dog, as recently reported in S Wales) dies.
Why should there be a leak? Well
you won't have tested for one, for a start. Then if the boiler's burning incorrectly it can soot up, overheat, all sorts - a leak would be likely. Probably not this week, no.
If a competent installer was doing it he'd know about it, but it's easy to forget if you're just checking a boiler. No need to check it when, say, doing a Landlords Gas Safety "Certificate".
You may have got it right, but you clearly didn't realise its significance, or you would have said. If you'd seen it and understood it, you would have not fitted the flue so the corgi could check it. I wonder what else is wrong that nobody's pointed out. Your corgi went through the commissioning procedure, he did not check every point of the installation.
I'm not anti-diy, but there are dangers. If you're relying on a phone call to get things right, mistakes are likely.
The guy at corgi would have wondered how the hell you could have been trained, to be asking such basic questions, and will have that recorded against the poor installer's name. So you've made his life a bit more difficult. He can expect an inspector on his back going through what you should have done.

Are you admitting that corgi registration is no guarantee of competence?
Mistakes are made, certainly. Gas Safety is covered in the training. One of the things that does is tell you why such things as flue restrictors are required. But you are told many times to do absolutely everything which is in the instructions - something our diy'er above didn't see the importance of. But the instructions alone are never sufficient.

Reading through this forum it seems that there are a lot of well informed DIYers out there
A lot are very bright, can read instructions, and understand perfectly well if something is explained. But if they don't know there's a hole in their knowledge, their confidence is misplaced. Nobody who hasn't been trained, for example, would do a gas leak test properly - and that's just one of the basics he'd get wrong.
