I am installing a flue, straight out of an oil boiler, through an external wall and the distance from flue to fence is just short of the Regulations 600mm, as on picture A below. Are the inspectors going to be so tough that, if they spot it, they will get me for 35mm short of the spec?
Alternatively, I could pull the flue back a bit by carving the brick wall around it to make room for the air to flow into the vents as on picture B.
Otherwise I need to install a high level flue to go over the fence which will cost money (credit crunch), will complicate my internal installation and I may get trouble from the neighbour.
It looks like they don't let put links to image websites directly so here is the link to the image. Sorry
