I am thinking of having a new boiler fitted, in a new position, within my 
home.

I am in an end-of-terrace and I would like have it fitted to this outside 
wall. However, there is a public footpath running directly alongside this 
wall. I have tried to find if there are any regulation on the positioning of 
boiler flues in relation to public footpaths but can't find anything - can 
anyone advise on this?

I am aware that if a flue is below, I think, 2m it must have a "cage" 
covering it to stop anyone being burnt by touching the flue.

Thanks for any advice.
