Tell him it's because it's the regs and he doesn't need to know why. He just needs to accept it. Plain and simple.

To engineer around it runs the risk of turning it into an illegal installation and one anyone in their right minds would be walking away from.

Baz. I need you to pm gas man or REDSAW with your gsr details please.
 
Some people in this world do not just accept that is the reg`s if we did then nothing would ever be designed or built that solved problems it would be a sad world to live in when you think about it !
As stated vaillant have a flue they say is ok at 50 mm from structual opening for combustion air but without a chat with technical not sure about that one !
The other thing is as said many will take the line Ooooh I have not seen that before and yes they will class it as an illegal installation when in reality it will not be ?
Always springs to mind when a client decided to have a timber ceiling with exposed beams Mr building inspector said it had to be removed ! His boss said we can sort this another way find me a product to fireproof it and all will be ok .
Was a specialist painted fancy ceiling costing thousands but we found a matt clear coating so job done .
 
Did anyone mention to you that you need to read the MI?

I think we all get that one it seems to be the favourite for question setters in all subjects to the point you get sick of answering with I would refer to the manufacturers instructions or operating manual etc !
My point is I do not want to trawl about if someone has a simple answer and says Oh yes we do a couple of those a week with this manufacturer and this flue kit .
At the end of the day I always try to help anyone out as I like to think they will do the same for me one day
 
I don't entirely disagree with you but every boiler has to be installed in accordance with the manufacturers instructions and the regs in place at the time. As a gsr you know that.

Each boiler is designed and tested to ensure safe operation. To jury rig something to get around the regs is not only foolhardy but downright dangerous.

However, should he get the say so from the manufacturer in writing that they're happy with any modifications then fill your boots.

But make sure you get a copy of said letter attached to your paperwork should gas safe come knocking on your door.

Yes I would do along with any calcs he has done for the opening that close to a structual opening and attach both to the boiler manufacturers instructions too ao he can wave them in the face of Mr Ooooh I am going to have to report this one .
