Have family members currently putting up a conservatory for me. Last week I noticed the boiler flue inside the conservatory. When I queried it, they told me they were putting attachments on so it comes out of the side.... I have queried 2 gas engineers who haven't been very helpful. Just wondering if anyone can advise me on what to do. What to not do. And the regulations. I have looked at the manual, but am pretty useless. Have uploaded photos of the area its stressing me out to the max
