Can anyone clarify the building regs regards whether a modern condensing combi boiler flue oulet can be over a public pavement? I was told by a B&Q asistant: "Yes, as long as it is 3 mtrs above the pavement". Is that correct?
Also, he said that the flue itself cannot be more than 3 mtrs in length and that a 90-degree bend counts as 1mtr. Is that correct?
What about the drain pipe for the boiler? Can that spill out onto a public pavement? The B&Q guy said 'yes', but can someone confirm?
Many thanks,
Rich W
