I've got a "standard" flue outside my flat, see pic. The boiler was put in more than 10 years ago, the canopy was put in about 4 years ago. I've now trying to change the boiler but I've been told by one installer that I need to have a long flue that extends beyond the canopy to prevent any build-up of flue gases.
Another installer started saying the same but then measured the distance between the current flue and the top of the canopy, came to over 3 feet. He said that was enough to fit a new flue as it is now.
The canopy was put in by the LA and they say that it's all perfectly fine as they've put in boilers since the canopy went up. There's 25 flats in my block and they all have the same "standard" flue, as does all the other similar blocks.
Who's right? What Health and Safety rules is the 1st installer talking about?
